Re:Mozilla is a great browser if...

[jacoplane]

If the only part of mozilla you like is Gecko, then use only gecko with a simplified interface.

For linux, try Galeon

For windows, try K-Meleon

Re:Mozilla is a great browser if...

Well lets look at the system requirements, which as we all know are very conservative

Windows
* Intel Pentium-class 233 MHz (or faster)
* 64 MB RAM
* 26 MB of free hard disk space

Linux
* Intel Pentium-class 233 MHz (or faster)
* 64 MB of RAM
* 26 MB of free hard disk space

Since you probably can't upgrade your processor on your board maybe you should try and bump your RAM to 128MB or so? That would definitely help out. Otherwise I recommend you give Opera a shot. It's right up your alley and it works on Linux and Windows :)

These are the days

[Sludge]

I'm going to miss these days. My favourite browser gets massive improvements every couple of months.

Idea wishlist:

• Ability to bring up my $EDITOR when typing in a textarea
• Plugin missing popup isn't so annoying (I refuse to install flash)
• A clean looking theme that isn't netscape 4-ish
• More usability based around the tab feature. That thing is wonderful!
• A way to delete the contents of the URL bar without destroying the contents of my clipboard. Right now, I copy a URL from somewhere else, then click in the URL bar and hit delete, just to have the contents of the URL bar copied to my clipboard.

I'm a very busy person who does some good for the community already in his free time, so don't ask me to implement these features. I just don't have the time.

Perhaps this would be a good time to ask... does anyone know of a proxy that allows you to rewrite packets on the fly? I think the web's got to the point where I want to start overriding some HTML arbitrarily. I know regular expressions, so some sort of regex interpreter would be quite handy.

Already done: Highlight the URL you want in some other application and then middle-click in a blank spot on any Mozilla page. You can even set this up to open a new tab with the tabbed browser by going to the new tab preferences under 'Navigator'.

Re:Cross-platform performance.

[Anonymous Coward]

Er, nice try.

The main reason is that Mozilla makes pretty heavy use of pthreads, and pthreads don't exactly fly on Linux. Windows threading performance is definitely superior to Linux's pthread performance, at least on single processor systems. Why?

Windows is absolutely useless at process creation. Windows threads are about as heavyweight as Linux processes, and Windows processes are hopelessly heavyweight. So, the traditional Unix model of using many processes to complete complicated tasks completely fails on Win32. Microsoft's answer to this failing was to make threading as fast as possible, and to push multithreaded programming as a hack around a fundemental OS problem.

Back in Linux land, the relatively low demand for mutlithreaded apps (because the Unix model really works quite well if you have fast process build up/tear down) finally pushes Linus and friends to implement clone(). The clone() system call was based on Plan9's thread model, and is actually much faster and more advanced than Win32 threads, totally beating out of almost all standard OS kernels at thread performance.

So, now Linux has both faster processes and threads, but thread performance still sucks. Note that I said pthread performance on Linux isn't very fast. Pthreads are POSIX threads, and have very different semantics from clone(), mostly to support implementing multithreading in userspace (ick). So, the standard is a hack to say the least. Unfortunately, it's still a standard, and Linux must map pthread behaviour to clone() in userspace, which is painfully slow. It requires multiple context switches just to created a pthread on Linux. So, pthread-heavy programs like Mozilla just crawl.

So, the moral of the story is that Linux has a much better core, but seeing that the Linux community actually cares about standards, performance isn't quite up to snuff.

Re:Cross-platform performance.

[anthony_baxter]

I find that building with mondo optimisation makes quite a difference to how fast mozilla "feels". I also turn off mail/news - I don't care, I don't need it :)

From my .mozconfig:

ac_add_options --disable-mailnews
ac_add_options --enable-optimize="-O4 -finline -fno-omit-frame-pointer -march=pentiumpro -mcpu=pentiumpro"

I don't know what build options are used for the milestone builds...

Re:Cross-platform performance.

[rmathew]

"JayPee" has made available Navigator-only optimised builds for Linux that you might find useful.

Re:Better and Better

[pthisis]

- You can disable Mozilla's JS window.open()
A nice feature, true, but what happens when you go to click on a "help" icon and it can't open a new window?

The mozilla anti-popup feature disables popups on window open, page load, and window close (and timers). So obnoxious auto-pops don't happen, but e.g. The Onion's horoscopes still work.

Re:Cross-platform performance.

[Simm0]

Unfortunately this high optimization (>= -O3) will not work while compiling with GCC 3.0 which currently has a strange bug which will cause mozilla to crash on startup. A patch was checked in early today that fixes this problem on the mozilla trunk.

Re:Better and Better

[nathanh]

[Re: Open Source nature of Mozilla] Zealots aside, why is this better? Have you modified any of the source code? Have you contributed? Have you searched through it to make sure there are no back doors that mail out your keystrokes? Or are you karma whoring?

• No single entity (person or company) can control the distribution or ownership of the browser. This neatly avoids the problem of a single vendor trying to control standards.
• No product lock-in: "must have" features can always be lifted and used in another piece of software, if the mozilla monster turns out to be an unwanted burden.
• The software is not rushed to completion (2 years of delays proves this!) so I have faith that the quality is better than most other browsers.
• Development is driven by demand not money. This means the engine implements features that people wanted, not just feature "checklists".
• The GECKO engine is portable and has been ported widely. This means I'm not locked into a single operating system or hardware platform.
• There is no limits on how the engine is used. This means I see the same engine rendering my help files, my email, my webpages, etc.
• Though I might never read the code, I know somebody else can, will, and has.

Build Options

[Simm0]

Here are a couple of build options that I frequently use in my .mozconfig when building mozilla to keep it running extreemely well also cutting alot of the cruft out.

These build options are for all the people that are complaining about shoddy mozilla performance under linux and people that would like to have a look at some really new features.

ac_add_options --with-extensions=all
Enables such things as the Chatzilla IRC client and the dom inspector(which I think is extreemely neat for debugging and viewing dynamicly changing html object model) also contains some very experimental things such as xmlterm.

ac_add_options --enable-mathml
Very neat standard for displaying math of all types and sizes in xml.

ac_add_options --enable-crypto
Great option, about a year ago this option wasnt even possible due to netscape not realeasing it's code due to US laws afaik. Now everyone that want to compile the lizard can get ssl support built right into the browser.

ac_add_options --enable-optimize="-O3 -march=i686 -mcpu=i686"
The main optimization part. This option has the biggest leaverage affect on the actual quickness of the browsre itself.

ac_add_options --disable-tests
Get rid of the unneccesary tests.

ac_add_options --disable-debug
We don't need any debuging symbols in th build if where not a developer do we.

ac_add_options --disable-shared
ac_add_options --enable-static
A nice new enhancement of the moz build system which links all of the modules in statically, im experiencing a big speed increase and a decrease of startup times with this option probably because it doesnt need to read each individual shared object from the hard disk.

Re:Threads and Processes

[bgarcia]

This statement puzzles me greatly. How can Linux threads be faster yet their performance still sucks?

I think he meant to say that the linux kernel threads (clone()) are faster, but the *pthread* calls are slower.

This statement implies that Linux has POSIX compliant threads which the last time I checked is not true especially since the primary kernel hackers (Alan Cox, Linus, etc) are against it.

Linux does have POSIX-compliant threads. The kernel does not, but there is a pthread library that implements the pthread functions to work with linux kernel threads.

Better cookie viewing before accept/refuse

[weave]

IE 6 now tops Moz in the cookie/privacy area because you can set IE to prompt before each cookie and remember the accept or refuse action for later (as you can with Moz), but it also allows you to see the cookie contents to help you decide what to do with it as well.

Opera and Konq also have this nice feature.

I'm hoping Moz steps up to that plate soon....
