Switch Proxy Tool

[wbav]

If you have the Switch Proxy Tool, I strongly suggest you disable it. Caused all sort of issues when upgrading. If you've already upgraded, right click on the shortcut and run in safe mode, there you can disable it. YMMV.

I used someones firefox with these persona things already installed...it was awful, I couldn't see which tab was what.

It was like giving myspace page designers control over your browser

See? This is what happens when the Mozilla people come up with their own ideas instead of just implementing the features from the previous version of Opera.

I keed, I keed!

[zullnero]

Awesome. I love having as much freedom to make my browser as irritating to use to my jerk friends who don't ask for permission to use my machine as possible. It's just a thing I like to do.

This is why people complain about bloat...what is the point of this junk? Weren't there already addons/themes that let you do this kind of stuff?

It's the first step toward replacing Firefox's old theme system with a better one, where themes are smaller and easier to create. (It's not there yet, since you can't replace buttons, only backgrounds.)

While we have both systems in place, it might seem like "bloat", but in the long term it will allow Firefox to use significantly less memory and have a simpler user interface around installing themes. It's a fight against bloat.

I hope that mouseover to change style stuff only works on mozilla domains

Correct, it only works on sites that are whitelisted for extension installation. By default, the only whitelisted sites are the mozilla sites for extensions and themes.

Pretty neat.

[jayminer]

Tried on Windows, performance improvements are immediately noticeable. Wastes less screen space by default. For those who are used to the old look-and-feel can feel a little awkward at first.

Set extensions.checkCompatibility to false and you're good to go.

Javascript performance

[mallumax]

My javascript performance comparison between Firefox 3.6 and Chrome and Safari http://www.manu-j.com/blog/firefox-3-6-vs-chrome-vs-safari-javascript-performance/432/

As usual, Firefox performance on the v8 benchmark is pathetic where Chrome is more than 10 times faster.It is 24% faster than version 3.5.4 in V8 but it is clearly not enough. In the sunspider test, chrome is 2 times as fast as firefox. In this test, 3.6 is 17% faster than 3.5.4. Safari too comfortably beats Firefox in both these benchmarks

Re:Javascript performance

[Skratchez]

It's an improvement. That's what counts, some of us don't want to trade our lovely open-source browser for a product from Google or Apple, or MS for that matter. I can wait on javascript performance, TYVM.

Re:Javascript performance

[Dan667]

The problem is there are just not the plugins for other browsers. Even though some folks are obsessing over rendering times, the extensions add to block flash, malware, adblock, etc make Firefox faster and the web more usable for me.

Re:Javascript performance

[Zocalo]

That delay is nothing to do with your browser - that's Slashdot scanning of a bunch of ports on your IP address. I spotted this a few weeks back when I made a post to Slashdot while running a "tail -f" on my firewall logs, although I've been aware of the lag a lot longer than that. It seems that if your firewall just DROPs the packets you get a delay while it retries a couple of times, whereas if you REJECT then it's a good deal quicker. There's some caching going on as well, once you've gone through this the lag disappears for a day or two, then re-starts. As it says in my .sig - WTF?

Re:Javascript performance

[Anonymous Coward]

They are checking to see if you are an open proxy, and will ban you if so.

Re:Javascript performance

[shutdown -p now]

These tests are mostly pointless anyway. They measure raw JS performance, which would matter if you'd be doing, say, number crunching. In practice, the most heavyweight operation that is likely to be done by scripts in a browser is DOM manipulation, and that's an entirely different thing. What does it matter if your super-efficient JS AOT compiler based on quantum branch prediction can call a method on a DOM object as fast as a plain native JMP, if the implementation of said method causes reflow and redraw of most of the page?

Coincidentally, it's why Opera feels so fast for actual browsing while still using an interpreter for JS (and consequently sucking in any synthetic JS perf tests) - its interpreter is an order of magnitude slower than e.g. Chrome, yes, but it's got an extremely fast layout engine and renderer, so DOM updates are instantaneous.

Re:Javascript performance

[mrdoogee]

Chrome is open source in the same way that OS X is open source.

Sure they're both based on a open source project (Chromium/Webkit and Darwin/BSD) does not mean they are truly open source. Try to modify and redistribute either and see how long before either of their "parents" get all lawyer-ey.

Remember kids, free doesn't always mean open source, and open source doesn't always mean free.

Re:Javascript performance

[Zocalo]

Not SMTP; HTTP. The ports scanned are all common default ports for web proxy applications like Squid's :3128, various ":8080" type combinations and such like. I'd have to go digging through my logs to get the complete list, but I'd guess there are about a dozen ports checked in total.

What's so irksome about it is that it's a straight SYN scan done very slowly that impacts any users that have a firewall that DROPs packets with an apparently inexplicable delay of several seconds. If you really feel the need to do this, which the Slashdot team obviously does, it would be much quicker and less annoying for users do the scan at a faster rate without the two or three retries currently used. Better yet, kick the scan off in the background while the data is being entered data into the form and reject the post if necessary when the "Preview" or "Submit" button is clicked. Even if a post is submitted through an open proxy before the scan completes, Slashdot's delay between posts from the same IP will ensure that only one post can get through before the ban hammer comes down.

Re:Javascript performance

[amRadioHed]

That delay is really annoying. If they need to do it they should start it in the background when you preview and then by the time you post it should be done and they wouldn't need to make anyone wait.

The analogy Chrome : Chromium :: OS X : Darwin/BSD is nonsense. You can't build an almost identical replica of OS X from open-source code, or anywhere close. Chromium is fully open-source, and it's essentially identical to Chrome. It's what the Chrome developers themselves use for development and testing.

The competition is heating up!!

[igadget78]

Microsoft's patch vs. Mozilla's release. I can't wait. The Excitement is almost too much.

Re:Speed Kills (play it safe - buy a Chevy)

[Anonymous Coward]

Firefox 3.6 does beat the newest Chrome on some Javascript benchmarks (and Chrome beats Firefox on others). I think it's safe to say they're in the same ballpark. http://www.fudzilla.com/content/view/17199/1/

Personas, lightweight themes?

[Anonymous Coward]

Proof that Firefox is heading for doom. Stop wasting time on making the browser look different than the fucking OS you idiots.

Re:Personas, lightweight themes?

[Stormwatch]

Stop wasting time on making the browser look different than the fucking OS you idiots.

Hear, hear, goddamnit, HEAR! Consistency is an essential quality of a good user interface. That's why I could never really stand Opera: you can make it look like anything, but good luck making it look like it belongs. And that's why I love Safari on the Mac, yet hate it on Windows: it looks alien to the system around it.

Here's a tip -- go to the themes page and look for something that fits your OS. Looks like custom themes are immune to this Persona shit.

Re:Speed Kills (play it safe - buy a Chevy)

[Cheburator-2]

Just downloaded it - it's just as fast as Chrome or even faster. Typing this from shiny new browser.

GPU accelerated Firefox?

[Anonymous Coward]

One of the goals mentioned in the article was to improve garbage collection performance to make pauses shorter and animations smoother. Why not just use the video card to accelerate the graphical operations (plus any other GPGPU operations)? Flash and PDF readers have already done it. For that matter, Windows Vista or later UIs have already do the same. This will give performance edges over contemporary browsers.

It's extensions.checkCompatibility.3.6

[wiredog]

Seethis for details.

Scrolling

[Majix]

It seems the mouse wheel scrolling has been changed in 3.6. It's moving a much larger distance with each "click" of the wheel than before and if you scroll continuously it seems to accelerate even faster. My first impression is that I don't like it at all. It feels a lot more like Chrome, which isn't a good thing in my opinion, the annoying jumpy scrolling is one of the primary reasons I prefer not to use Chrome.

Re:Scrolling

[ddegirmenci]

about:config
set mousewheel.withnokey.sysnumlines to false
set mousewheel.withnokey.numlines to 3

As good as new... Wait a second.

Re:How can I upgrade on Ubuntu?

[Hatta]

Wait until the maintainers put a package in the repository, then update like usual. It's generally not worth installing unofficial packages if an official one is forthcoming.

Open Link in New Tab changed

[bughunter]

The new tab now appears to the right of the current tab when you right click on a link and select "Open Link in New Tab."

I just discovered that after about 5 seconds of "Hey, where'd my new tab go??"

Re:Open Link in New Tab changed

[shutdown -p now]

Good, because that's how everyone else (i.e. IE, Chrome, Opera) have been doing it for a while now.

Re:Open Link in New Tab changed

[Paradigm_Complex]

I prefered Firefox's older way of dealing with this. To revert, go to about:config and change

browser.tabs.insertRelatedAfterCurrent true

to

browser.tabs.insertRelatedAfterCurrent false

Re:Speed Kills (play it safe - buy a Chevy)

[headkase]

I ignore all moderation here, especially down moderation as that is always disagreement. There should only be positive mods and they should not be limited to 5. Set your threshold wherever you like with that. There are no consequences to moderation any more either as the only thing it used to affect, order of comments if you used that no longer really exists.

Personas...?

[Stan Vassilev]

Mozilla has released Firefox 3.6 today, which adds support for Personas, lightweight themes that can be installed without restarting the browser

I think someone just jumped the shark.

I can't explain to myself how adding a theme engine on top of another theme engine was somehow near the top of their todo list.

Re:How can I upgrade on Ubuntu?

[Knuckles]

How can I upgrade on Ubuntu?

It won't appear in the main distribution until the new distro release 10.04 (current Codename Lucid Lynx). Possibly someone will stick it into the backports repository (which you would have to enable) or into a PPA (likewise).

If you can't wait, install into /usr/local from mozilla.com (use checkinstall to create a basic deb package so that the package manager knows about it).

Re:Speed Kills (play it safe - buy a Chevy)

[zullnero]

Ha, and you got tricked by a Opera or Chrome fanboy into replying. You know that's not going to make them change.

how about making FF fun again

[cinnamon colbert]

The GUI that pops up when you want to bookmark something - case study in bad design
How about a real editor for bookmarks, with some minimal feature like export this folder (when you need to send someone a bunch of stuff)
How about mozilla not being a jerk about extensions, and getting rid of the spam that makes it hard to see anything but the top 5 extensions big brother mozilla thinks you should have

How about a stable platform for extension developers

How about letting the world know how awesome FF+noscript+adblock is when you go to a site like YAHOO
I hadn't been to YAHOO wihtout my little protectors, noscript/adblock/flashblock for some time and was astonished at how much ads have taken over the front page - how can people stand it

how about giving the users some control over privacy, so we have the wipe things clean on exit menu again

how about giving some users an idea of how much info the SOBs of the web, like google, are collecting

I'm sorry but this is pure bloat.

[Requiem18th]

Personas could work AND WAS ALREADY WORKING as a lightweight theming replacement without being tied to the browser code as an addon.

REPEAT: It already works as an addon.

This is essentially an unremovable addon like that MS .NET addon that MS shoved down our throats.

Look, I have for the most time defended Firefox ever increasing features as progress. I already don't think they managed their "awesomebar" well at all, I like it but many loyal users didn't and instead of making it an option or an extension they gave it a hip name to add insult to injury.

But now they are taking an already working addon into the browser.

The thing I liked about FF was it's modularity, it's what caused the browser to split form the mozilla suit in the first place. This is a step into the wrong direction, into a more monolithic application.

Why do FF developers hate their own extension framework dammit!?

Re:I'm sorry but this is pure bloat.

[Ant P.]

Why do FF developers hate their own extension framework dammit!?

Be careful what you ask for...

Let's imagine for a second that you're writing a HTML web page with some scripting. If this were Chrom(e|ium) you could stop reading here; this is how their extensions work. But as a FF extension writer, you don't get the luxury of preserving your sanity.

Take away all the HTML you know and replace it with XUL, a completely different XML language with a different box model. Actually, you can keep the HTML in addition. You can keep your CSS too - along with getting to learn a metric assload of browser extensions to the syntax and creative ways to hack the existing vocabulary to get results. Want to display an image? XUL doesn't have the <img> tag, or a box model with sufficient control to embed a background image, but hey you can use "list-style-image"! Oh and since it's XUL you get to have fun with overlays, which are like includes except they work in an XML/XSLT way.

At this point, I'd like to mention the average human brain can only hold 7 items in short term memory at once. So far I've only named the bare minimum necessary to make a UI that does nothing. Now to make that clusterfuck do anything, you have to use a dialect of Javascript that makes COBOL look terse. Still not scared? Then you might survive extension-writing long enough to get around to the RDF stuff...

I really don't blame them for hating it.
