64-Bit Firefox Builds
Official x64 builds with equal or better performance to the 32-bit builds will be available starting with Firefox 41 42?
Note: Don't use special snowflake third-party builds (Waterfox, Pale Moon), you miss out on security updates and add-on compatibility due to the lovely changes.

Firefox is crashing/being slow/acting weird/using a lot of memory. How do I fix it?
  1. Make sure you have the latest version of Firefox and all extensions.
  2. Use https://www.mozilla.org/en-US/plugincheck/ to make sure all plugins are up to date (specifically, ensure Flash is current).
  3. Ensure that you have the latest graphics drivers. You may need to use beta drivers on AMD cards.
  4. If it's still weird, disable all extensions. If Firefox acts normal with all extensions disabled, re-enable extensions one by one until you determine the culprit.
  5. If it's still weird, try disabling 3rd party plugins (VLC, Flash, Java, etc.) (plugins are different from extensions!).
  6. If it's still weird, try recreating a new profile using the built-in Refresh Firefox feature. Test extensions one by one again.
  7. If it's still weird, manually create a new profile. Test extensions one by one again.
  8. If it's still weird with a new profile, uninstall and reinstall Firefox.
  9. If it's still weird after doing all of these things, post in this thread.

I want Firefox to prompt me to save my tabs when I exit!
Set browser.showQuitWarning in about :config to true.

Firefox 7+ no longer shows http:// or https:// in the address bar. How can I get this back?
Set browser.urlbar.trimURLs in about :config to false.

I don't get the "interface" issues people have with Firefox. With just a few clicks, version 4/5/6 (and probably 7 and beyond) can look just like Firefox 3, 2, or whatever.
Put the tabs on bottom, put the status bar back, etc.

Yeah, I feel the same way. You can still get the performance/under-the-hood improvements by customizing the theme/userChrome.css if you really don't like the interface. But then again, I still don't understand how you can't like the interface. 4/5/6 is so much cleaner than 3.x.

This doesn't seem to affect vertical space use. Even if you move the Firefox button, the tabs aren't inline with the minimize/maximize/close buttons except when Firefox is maximized.

Ah, you're right. So the problem seems to be that while the Firefox button is moving, the minimize/maximize/close buttons aren't moving because the tab groups dropdown shows up below them. http://support.mozilla.com/en-US/questions/782562 looks like a good place to start because they are messing with the minimize/maximize/close buttons in userChrome.css.

http://www.mozilla.com/en-US/mobile/sync/

Basically:
  • All communications between you and Mozilla are encrypted.
  • All your stuff is encrypted on their servers with a 32-character (including dashes) key. They don't keep a record of this key, and if you ever lose it, you can't ever access your data again.

I upgraded to version 6 on my windows 7 desktop and macbook pro laptop. I have fireftp on both computers and it no longer seems to work on either computer. What's weird is that the add-ons menu says Fireftp works but there's no firestp option in the tools menu.

I've uninstalled and reinstalled (restarting Firefox) but that didn't work.

Uninstalling and reinstalling FF itself rarely fixes the problem because the problem is usually your FF profile (which doesn't get removed when uninstalling). Try creating a new profile. Something is probably fubar.

Just installed Waterfox, and i don't notice any difference between it and the Firefox Beta. Are there any, besides it being "supposedly" faster?

The whole point of the 3rd party builds is to enable support for SSE, SSE2, x64, and possibly some other instruction sets while also turning on some compiler optimization flags that Mozilla doesn't enable when they compile for whatever reason. I don't believe there are any other differences (but I may be wrong). There probably isn't a noticeable difference except maybe on really JavaScript-heavy sites.

Does anyone know of any comparisons done between vanilla FF and Pale Moon or Waterfox?

Pale moon makes a few additional changes, which he details here. Notably, he makes some UI changes in Palemoon 4.0+, to bring back a few features from 3.x (status bar, tab location I think). I run Pale Moon, but I actually went through the trouble to revert the look to stock Firefox.

Also, third party builds are not compatible with Firefox Sync (Mozilla's restriction). I suppose if you found a third party sync server, that would do, but I didn't think it was worth it.

This is probably the dumbest question ever, but I'm a relatively simple user of Firefox and have been for years. The newest version makes me livid, however, because it made the idea of keeping certain tabs open for days a pain in the rear end or unsuccessful with this "restore previous session" bullshit. Is there any way around this? I liked it when it prompted me to save tabs or not and that was that. I keep losing like 8 tabs that I never got around to and it's enough to make me want to jump ship or something, but I like the few extensions I do use and I'm pretty used to the new interface anyway.

Go to about :config, and enable browser.showQuitWarning.

Zhentar posted:

Multi-threading can be (and typically is) done within a single process. Splitting processes as in Electrolysis carries some significant benefits (reduce the scope of what's affected by crashes, improved security from restrictions on what can cross processes), but it also adds a lot of complexity to the development and adds a lot of overhead when things in different processes have to communicate with each other.

Mozilla could, with comparative ease, distribute more work onto background threads within the same process, and allow greater responsiveness from the main UI thread. In my experience/opinion, Firefox's only significant remaining disadvantage compared to a certain other browser is the smoothness; even after many years of supposed improvements Firefox still stutters very frequently.

Yeah, same thing. I really really want tabs as separate processes. In fact, if I had it my way, I'd tell the FF dev team to stop everything they're doing, and only work on tabs as separate processes. I think it's that important. Web pages are getting more and more JS-heavy, and a really complicated page can lock up the entire browser for a second or 2. Looking at individual tabs, I don't think there's really a speed difference anymore between Chrome and FF, but looking at the browser as a whole, Chrome is definitely faster since one tab loading won't hold up the others.

Is there any public discussion on the progression of tabs as separate processes? I know this was talked about as a big priority several years ago, and they got everyone all excited with plugin-container.exe, but then they just seemed to have stopped working towards splitting tabs into separate processes. The Electrolysis wiki page is extremely outdated.

To a large extent, it won't in Firefox either. Relatively few things require blocking the main thread, and those still won't necessarily block other tabs from continuing to load in the background. I think that now the most noticeable thing that will block the main thread is garbage collection, which can really stutter things up if it's working too hard.

This is a very example, but http://www.myfreecams.com/ locks up the entire browser when it loads. It happens as it's downloading all of the pictures (I do have pipelining enabled), but while it's downloading those images, I can't switch tabs or do anything else in FF except wait for them to load. Contrast this with Chrome which will allow you switch tabs at your heart's content while the page is loading. I've noticed similar behavior on really image-heavy tumblr sites.

With ALL extensions disabled (no Themes, no userChrome.css), it still performs like crap.
However, when I start Firefox in "Safe mode", Gmail performs way better. It says Safe mode disables all extensions, but it's obviously doing something more than that for Gmail to work so differently compared to a non-safe mode that also has all extensions disabled.

This isn't a profile issue, as it happens on multiple profiles and even on multiple systems (Windows, Mac).

I wonder if it has something to do with hardware acceleration. I bet safe mode doesn't have hardware acceleration enabled. Try disabling that to see if it fixes your issue (options -> advanced -> uncheck hardware acceleration). If it does, maybe try updating your graphics drivers (do that anyway).

Mozilla has run into an interesting problem: The Firefox codebase is now large enough that it can't be built on 32-bit machines because linking needs more than 3GB of RAM. They discovered this when a large patch suddenly broke compilation, and they've had to do a panicked backout of several features (including SPDY ) to get things building again. The solution is to switch all their build machines to 64-bit operating systems, but this is going to take awhile. In the meantime people are frantically scouring for old code that can be removed to buy time while they get 64-bit boxes up.

Keep in mind a few things on this: that includes tests and other things that aren't part of libxul (which is the library that until about 10 minutes ago was causing VS2005's linker to crap out on PGO builds). That does NOT include C++ code generated from the .idl and .ipdl files during the build, much (all? not sure) of which DOES become part of libxul.

If you want an ACTUAL LOC count, you have to include other file types, but none of those (unless I'm forgetting something) matter for the current issue, since they don't get linked into libxul.

Do the usual - disable all extensions, see if it still crashes, and if not, re-enable your extensions one by one until you determine the culprit. If it crashes with all extensions disabled, create a new profile. Also, make sure you're running the latest version of FF with the latest version of Flash.
