An error started occuring yesterday when Google/Youtube disabled Flash completely, everywhere. Even though I'm on old OS (XP) and FF version (39.0.3) I'm able to play 99% of videos even in high quality and at 60 fps (which is another problem I asked about in separate question). Thing is - there's that 1%, usually the newest videos, that I cannot play whith the error message saying that "Your browser does not currently recognize any of the video formats available". Thing is - I can play 99% of videos in HTML5. I just don't get it...

Hello, I've installed various games onto my computer such as Garry's Mod, and several other 3D type games that work perfectly fine without Firefox on, no crashes no problems. Several of my games (exception is minecraft), whenever I have firefox just up and running, it will just crash my computer. Black screen instantly, no warnings, just instantly switches everything off. I've scanned several times, I have no viruses and the games work normally without firefox.

But what could firefox be doing to cause my computer to crash with them on? Is there a way to fix it?

Firefox was too large for my monitor screen. So, I typed about:config in the address bar. Then I went to layout.css.devPixelsPerPx. I then made the terrible mistake of putting 2.0 in the box and the text went so small I can't do a thing in Firefox. I can't see anything on the screen even with a magnify glass. I am using my laptop right now. The problem is on my desktop. Vista Home premium 32 bit. I just downloaded Firefox yesterday. I did have Chrome on. They stopped supporting Vista so I thought I would use Mozilla. Remember, I can't see anything on the screen to be able to fix it. Help ,someone please!!

Unfortunately last night Youtube forced crappy HTML5 on everyone (they disabled Flash, addons are not working) and now there's an issue. Even though I have old OS (WinXP), old Firefox 39.0.3 (never versions have performance and stability issues) I am able to play most youtube videos in 1080p. Thing is, those recorded on 60fps are playing in 60fps as well. And that's the problem - that's too much for my computer, even at 720p/60 CPU usage is between 88 and 97%. I have AMD GPU and AFAIK last drivers do not support 60fps either (there will be no newer ones). Is there any way to disable 60fps and play higher resolution videos in 30fps?

So the new tab page of Firefox, used to have 15 quicklink tiles. However at random last night, it decided to go to 10. I cannot find how to set it back to 15. This is quite annoying as I use these websites often, is there any way to fix or set how many are displayed? As currently they only appear when the zoom setting is set to 80%. Which I cannot read anything at.

Youtube (and a few other sites) are forcing me to enable the now blocked Flash Player to view video.

Currently unable to use previously installed h264 (i.e. Core AVC pro) codec in Firefox. .h264 and vp9 playback is not enabled in Firefox on WinXP but works fine on other browsers including Google's Chrome.

Screenshot: http://snag.gy/iaQMd.jpg

Would like a way to point Firefox to the proper codec so that HTML5 h264 video can be played.

Thanks..

I had to restore my operating system. I was able to recover places.sqlite to restore bookmarks (good!). I was able to find a key3.db (dated July 2013) that file won't be complete or up to date, but at least it puts me somewhere ahead.

I read that I need a signon3.txt file to go with the key3. I don't have one. I did find a signons.sqlite file dated Sept 2014. I moved both these files to my profiles folder but I don't get my old passwords back.

Is it possible for me to use the old key3? Do the key3 and signons have to be dated the same? Is there a way to recreate the signons.txt?

I do have the master password.

Thanks for help.

Hello, is there any possibility to disable the session restore (using about:config or any other means)? I am not interested at all in saving the previous session, and I would like the browser would not drain any computer resource to make something I consider utterly useless.

Some time ago I used the preference browser.sessionstore.enabled set to false to inhibit this behavior, but I think it works no more.

Thanks in advance.

I only have the one Crash Report listed in "about:crashes". I was about to completely shut down my PC and was at the minute closing down Firefox when it occurred. Had closed everything else with nothing else open at the minute. All tabs, windows, etc closed. No music apps/videos or anything running. The only thing open was the Firefox browser and I may have been in the home start window - can't recall now. I closed it by clicking on the "exit" button in the Firefox menu.

If the dialogue box to report a crash had not flashed up on my screen as Firefox closed, I would not have known that it have crashed. It opened normally again after I shut down and restarted my PC.

Firefox 39 gradually uses up an enormous amount memory by accumulating ghost windows (126 at last count). Most of the ghost windows appear to be ad-related sites. Running in safe mode. This is easily reproduced by listening to music on Live365.com (non-VIP, so that you get a constant rotation of ads). Closing the Live365 tab freed all the ghost windows and a lot of memory. But it continues to accumulate every time that site is used.

Is this a Firefox problem, or should I blame the web site?

Firefox 39 will not load chase.com after login

Firefox 39 (and 38 before update) suddenly refuses to load one website: after input of username and password, it refuses to go further on Chase.com. There is no error message. It is simply a completely blank page. FF does not even appear to attempt loading the page as there is on loading indicator.

This is on two Macs: iMac with Mac OS 10.9.5 and Macbook Pro OS 10.10.4. Current FF version: 39 (but started with v.38).

Have done all the troubleshooting from FF website including a complete reset, restart, checking Network settings, and every other suggestion under "some websites do not load".

Have spent an hour with Chase support including (again) clearing all cache, cookies, history, reset Firefox, and attempting to login with temporary identification codes; sometimes I get to the next page to enter that code, but the following page is - again - completely blank or, I am not even able to enter the code as I wind up with a completely blank page. No error message at all.

There is no malware evident. There is no AV software installed (it's a Mac!). There is no problem with any other website, including other financial sites requiring logins. And, there is no problem loading that website with Safari, so it does appear to be an FF problem.

I have recently started encountering a problem accessing Google news links from my browsers (Firefox 39.0) and IE11 that involve a particular website – telegraph.co.uk. I keep getting the message Server Not Found. The long initial browser links to all other sites (Guardian, Reuters, FT, Daily Mail etc.etc) all resolve very quickly and show the required page….but not those to telegraph.co.uk. I can, albeit very slowly, successfully connect to telegraph.co.uk links via anonymox add-on proxy server – not ideal. We have2 other laptops, another pc, 2 ipads and 4 iphones in the household and none of them have my issue. My PC runs Windows 7 Home Premium , running Norton Internet Security (22.5.0.124). I regularly run Norton Live updates and do full scans daily. I also run CCleaner daily and regularly perform Malwarebytes and Spybot scans (with browser immunisation updated). I recently updated to this version of Norton Internet Security from previous version and this may be part of the problem although another pc and laptop also updated to same version and do not experience my problem. No evidence, that I can see, of telegraph.co.uk being “blocked”.

I have tried various “fixes”, unsuccessfuly, as follows: 1) We upgraded to fibre yesterday from ADSL and had to move to new router. I had hoped that this would fix my problem, but no. Re-set new router as well, but didn’t fix. 2) In Firefox Options, Advanced, Network I have tried:

   a.	Clearing cached web content
   b.	Clearing Offline web content and data
   c.	Also tried Clear history, recent history, everything
   d.	Connection settings were same as other pc: Use system proxy settings. I did try auto detect option but this did not fix. Have,    for now, switched back to Use system proxy settings.
   e.	Tried Firefox reset, to no avail
   f.	Tried running Firefox in Safe mode with add-ons disabled, but did not resolve problem.

A fix to resolve this very frustrating issue would be gratefully appreciated. Many thanks in advance.
