    How about that memory leak?

    1. Re:So... by kripkenstein · · Score: 4, Interesting

      High memory usage is different from memory leaks - every time you open a new tab it stores in ram some of the previous and next pages in ram. So if you do a lot of surfing on different tabs it very quickly goes up to 100MB in ram. You can disable that from the settings but you lose the ultra-quick back and forward capability. Yes, that's true, but it isn't the entire issue.

      I'm running Firefox 3 (the previous beta, not the latest), and I set max_total_viewers to 1, which should in theory do what you said. Yet I routinely see ~200MB used by Firefox, and on my 512MB machine I need to restart Firefox once a day or so, since a web browser taking up half of my RAM doesn't make for good responsiveness of everything else.

      One issue might be memory fragmentation in Firefox, or so I've been told. Perhaps someone who understands this stuff can clarify.

    I remember when Firefox first started it was meant to be a faster and more secure replacement for IE. Well, the longer I have been running it (many of you know that I was probably the last Slashdot IE6 holdout for various reasons) the more I realize how slow and awful it can be -- especially the last few versions.

    Now, I haven't run the new beta but I looked through the article and some of the past ones that have come up and noticed all this crap about theming, new features, etc, etc, etc but nothing really talks about how much faster it is and how much less memory the program consumes -- especially when it's been open for more than 24 hours on XP.

    So, are they going to go back to light, tight, and fast instead of this feature bloat that seems to have prevailed? Yes, it's nice to have bells and whistles but I think that it's just as important to have a browser that doesn't require me to close it and reopen it so that my machine doesn't grind to a halt every other day if I don't.

      Actually, the perceived performance issues of Firefox mostly stem from the fact it's a single-threaded architecture running on a JavaScript+XML interpreter (XULRunner).

      Extensions, which basically "patch" themselves into this single-threaded synchronous engine, often exacerbate the problem too.

      All XUL applications seem to share this slow response / performance problem, other popular ones exhibiting the same issue being Joost, Miro, SunBird.

      However this issue is so deeply ingrained in XULRunner, that I hear misguided excuses all the time, such as "it's about the RAM cache / CPU usage balance", which, oddly enough, no other major browser suffers from (I use all on a daily basis as a developer myself).

      About when we'll see improvements: most likely starting with Firefox 4, which is to completely replace the current JS engine, SpiderMonkey, with the one in Flash 9 (codenamed Tamarin), which compiles to machine code before execution, instead of being interpreted from opcodes.

      We'll hopefully see some threading too (one thread for the main UI and one per tab at least), although the lead Mozilla developers have some quite irrational fears of multi-threaded architectures.

Terrible memory leaks on OS X, sluggish performance, and a slowdown of innovative features. All that has been rectified. On top of that, 3 adds some real innovation to the browser space, such as the location bar "search-as-you-type" feature.

      Beta 3 has one new feature that I've been waiting years for - you can now type shortcuts in the location bar to reference installed search engines. For instance, if you've set up "g" as the shortcut for google, then type "g vegan restaurants" and you'll get the results immediately. Mozilla had this, but it never made it over to Firefox until now. Thanks to the dev who implemented this feature; I owe you a beer.

      So please, definitely try out the Firefox 3 beta. I think you'll be pleasantly surprised.

  12. usability by ceroklis · · Score: 2, Interesting
    Will this release be "usable" ? Seriously, for all the so called usability experts that they have this is one of the worst application in this department. (and it was supposed to be simple to use).
    A few examples:
    • Take the whole logic behind confirmation dialogs for the installation of extensions. The basic idea is that you do not want a simple click to trigger the install because you want to warn the user of the implications. Fine. The proper way is to do what explorer 6 does: ask for confirmation, have a little checkbox to bypass the confirmation for this site in the future if you want to, and if confirmed perform the action. Instead, firefox got it completely wrong. First, I can't authorize *just* this extension. I have to authorize every extensions from the site, which is generally not what I want. Most of the time, you don't known and trust the site sufficiently to blindly authorize everything. So to achieve this, after installation, you have to dive in the preferences menu and try to remove the authorization. Fucking morons. The second problem is even worse. Instead of having the sequence 1. click 2. accept 3. the action is performed, you actually have to retrigger the action ! You have to find the installation link a *second* time, and re-click on it. This is totally brain-damaged. To sum up: to install one (and only one) extension requires 2 (or 3) clicks in explorer 6, *14* in firefox (I just tried it). double fucking morons.
    • Another thing concerns the update to extensions. Do you really need this "do you want to update your extensions" dialog right when you start the program ? The average user, who might have had an extension installed by a techie friend, shouldn't even know what an extension is. Way to scare him away. Fucking morons. This thing should happen automatically, or maybe with a little thing in the statusbar (à la windows update notification in windows). This way the average user, who by principle, doesn't touch what he doesn't understand, won't be confused.
    • About the update thing again. The great thing is that if you say ok, I'll please you, do your updating stuff, firefox conveniently blocks until the update is done. Which is great for unsuspecting users who are in a hurry to check their emails and expect this stuff to be done in the background. Fucking morons. I guess they will just fire iexplore to get the job done while firefox is blocked. What are they thinking ?
    • Can we talk about plugins ? Is there any reason why firefox should freeze for 30 seconds while a page loads java ? Or even crash ? Ever heard of the idea of loading in a separate process ? Don't tell me it is the fault of the plugin writer, it isn't. This should have been fixed years ago. For an example of an application that does this right, look no further than the gimp. Plugins are loaded as separate processes and cannot bring the app done.
    I'll stop there before I break my blood pressure monitor. But seriously, usability wise (I am not speaking of the underlying engine), this is a piece of crap. And to think that firefox was supposed, among other things, to fix usability issues in mozilla suite. sigh. So please, use your millions to create a usable program and shove your themes,tag,semantic crap you know where.

    You are warned of this as soon as you visit the site in an unrecognized browser. Luckily, they let you continue and try to log in anyway, but you soon discover the truth of their warning. Opera/Konqueror users are greeted with "We are experiencing technical difficulties. Please try again later."

    Don't even bother trying to view it in a mobile browser. Well, I suppose you can get through to a garbled version using the mozilla-based Minimo 0.2 if you can stand to wait long enough.

So I have my personal CSS forcing fonts to a minimum size... which makes some pages ugly, and other pages unreadable (depends on how much the page designer hard-coded with pixel sizes). I'm also using the ImageZoom extension to scale up images... which means the scaled images cover up lots of text on many web pages, and fancy graphical navigation buttons often don't match up with their clickable regions.

    And I have a 16:10 ratio monitor... which means that often I will read a web site and there will be a narrow strip of text in the center, and tons of wasted space to either side, again because some web designer hard-coded things with pixel counts.

    I used to wish that web designers would make sites that can adapt to unusual screen sizes. Well, the WYSIWYG tools aren't going away, so now I just want to zoom my pages.

It's one thing to have the browser use lots of memory while I've got all the tabs open - but when I've finished with them all, and just have the original page back, or even hit "Home" to get "about:blank", the browser typically *still* has over 100MB of RAM and is often burning 20-70% of CPU. That's a memory leak!. Firefox 2 isn't significantly better than later Firefox 1.x versions - I'm hoping 3 will be at least a bit better.


    Do you know which settings to disable? Usually I don't mind if moving from one tab to the next is a bit slow - I've got lots of CPU, except when Mozilla tries to burn it all, and it's often slow anyway because the machine's busy paging/swapping heavily.

  17. Threads are harder than you believe by Nicolas+MONNET · · Score: 5, Interesting

    Actually, the perceived performance issues of Firefox mostly stem from the fact it's a single-threaded architecture running on a JavaScript+XML interpreter (XULRunner).

    There is indeed only one thread handling the UI and DOM, but there are multiple threads. Network operations, file decoding and so on run in separate threads from the UI. MAking a multithreaded UI is quite hard; note that IE (at least 6, most likely 7 too) does that too, with the difference that you can have separate windows in different processes altogether; but then they can't talk to each other through JS.

    The only time this architecture is really a problem ATM is when JS from a page sucks up CPU: it bogs down the whole UI.

    Moving to a fully multithreaded architecture is a very hard problem, esp. for such a complicated application, with such complex interactions as a web browser. Every single little thing would have to be synchronised, with big deadlock risks at each turn.

    The only possible approach is to divide work among threads such as there is minimal, well understood interactions between them. You can't for example just have one thread per window, because HTML+DOM+JS expect to be able to touch other windows from the same domain. You could divide processes by originating domain; that's what Apprunner does.
    But then you have coordinate communication between the windows and the bookmarks, history and so on. Not too hard to do, but has to be weighed against the minimal gain.

    Eventually, we will have to take advantage of many-cores CPU. That means that even DOM parsing will have to be multithreaded, for use on ultra low power 256 cores mobile cpus. Robert O'Callahan is working on this. But what you have in this case is a number of related threads with a very limited scope, and precisely defined interactions.

Running javascript in it's own thread sound easy, until you realize that almost all javascript operations, modify the DOM and thus need to run as gui operations because they trigger gui callbacks.

      The correct, but also very costly(In code size and performance) way to do it is that all gui operations must
      be put in a object/struct which are then inserted in the gui queue, where the gui thread will then perform the actuelly gui operations.

      But that is much work(And quite diffucult to get right), because when a javascript changes the dom, insted of just performing the needed drawing operations by calling the drawing operations in the Gui toolkit, it need to save all needed information for the drawing operation to an object which are then put in the gui drawing queue. But now your javascript is running out of sync with the gui, because the javascript continues without knowing the status of the drawing operations it have started. (Which can be solved by the gui thread, calling back to the javascript, but then things get really complicated).

      Now if only the gui toolkits were allowing multi threading, things would be much more easy, but all known toolkits require that only a single thread is the gui thread, and only that thread, can send drawing/gui operations to the toolkit, and only that single thread can recieve callbacks from the gui.
