After updating to Firefox 27 all webpages take a few dozen seconds to several minutes to load. When loading a webpage Firefox's status displays "connecting" and the CPU gets maxed out with 95 to 100% of its cycles taking by Firefox.

The computer is older so it is a little slow but Internet Explorer 8 has no trouble opening the webpages and neither do other computers on the LAN so it is not a network issue. I have tried restarting Firefox, disabling add-ons, deleting add-ons, disabling hardware acceleration, restarting the computer, and reinstalling Firefox after wiping every trace of it and its user data from the hard drive and registry.

CPU: AMD Athlon 2800+ 2.08GHz RAM: 1GB OS: Windows XP Home Edition Service Pack 3 32bit

I just checked task manager, since my computer was running a bit slow, and found firefox to be using nearly 1.2 GIGABYTES of RAM, with only 4 tabs open + Chatzilla for IRC. I have Skyrim running at the same time, and it is using LESS RAM than Firefox is!

I've tried disabling plugins, to the point where I only have the Flash and Adobe PDF ones running, I had to disable the plugin container since it crashes repeatedly (Usually at least once every couple of days). I tried using the "Free Memory" options in about:memory, and they do literally nothing to reduce the RAM usage. It's normally between 400 and 600 MB (Which is still insanely excessive for a browser). Closing Chatzilla only reduces the RAM usage by about 10-15 MB, so it doesn't seem to be the problem.

How in the name of all that's sacred is a browser using more RAM than a modded version of Skyrim?

I have the latest version of Firefox (26.0). I'm not sure if a Flash or Java update caused this issue.

Vine videos were playing fine in my browser. This was AFTER I changed the about:config settings for media.windows-media-foundation.enabled to "false" - They never seemed to load when this was set to "true"

But now, the problem is back. Vine videos will not play. I recently updated to Firefox 26.0 and this issue came back. Additionally, I did install a Java update. I have tried EVERYTHING to restore my browser to the way it was but nothing works. I have reinstalled Firefox. I have done clean installs of both Flash and Java. I have tried starting Firefox in safe mode, but the problem remains.

If I go to a Vine page (https://vine.co/v/heXdnb0m3dm) for example, all I see is a static image. I can't click on anything. It's just a static frozen image. On Twitter, the same Vine video appears as a black screen where it previously used to load just fine. Even on Tweetdeck, which uses Firefox as the default browser, the videos will no longer load. This is all when media.windows-media-foundation.enabled is set to "false"

If I change the settings so media.windows-media-foundation.enabled is set back to "true" then the video plays but I have no control over sound. There is, in fact, no sound. The video plays on a loop. No sound. In fact, I can not even control the sound icon. Clicking the icon does nothing. It doesn't change to signify that the sound is on or muted. It remains the same muted icon.

So, basically if I try to play Vines by forcing them into flash, I get nothing at all. I get a static image. No video. No sound. No function.

If I leave the defaults the same and play them via HTML5, the video plays, but there is no sound and no control.

Please help! I have tried everything at this point!

UPDATE: I temporarily set security.csp.enable to "false" and the pages load up perfectly. Is this safe, though?

I've cleared cookies multiple times

I've emptied the cache

I cleared my download history, and a majority of my browsing history

I've tried having hardware acceleration for both flash and firefox on and off

I turned off all my apps and plugins and when that did nothing I turned back on the ones I need. I never had a lot of apps to begin with. only a max of 5. I had quite a few plugins, but i disabled all but quicktime, flash, and silverlight. I have those three set on "ask to activate" so none are "always active" anymore.

I also tried a couple things from the FAQ and forums here about changing a few settings in the "about:config" setup.

A few of the above things initially worked, but after a day or two it'd be back to sucking up my CPU and memory. I would then try the same thing again, and this second time there would be no improvement. The real memory will fluctuate between 200 MB and 1.7 GB, and has done so for quite a while.

Even after I've left streaming sites, and sites with lots of images, and I'm not downloading anything, the memory and the CPU will still do that. I only have a handful of tabs open at a timeusually, and all of them are mostly text. I'll quit and reopen firefox, which will initially bring the memory and CPU usage down, but it inevitably climbs up quite quickly, regardless of my tab usage. It'll be the same if I'm playing a flash game or scrolling through blogs.

I never had any of these problems with Firefox 23, and my internet usage habits haven't changed at all. I had some of this slowness a few times with version 24, but nowhere near as bad as this, or as constant. Almost everyday I end up googling for other ways to speed things up. Everything I do never slowed down Firefox on earlier versions.

I've tried all my usual tasks on Safari which will never climb above 30-40 MB of memory, even on netflix streaming, or flash games, and the CPU will average around 8 and 11%.

A few days ago I set up my laptop from scratch after a long time of not using it. In the process, I set up Firefox Sync to link it to my desktop's browser. This is the only thing I have changed recently. However, after rebooting my laptop, I noticed that whenever I closed the browser and reopened it, it would not restore my previous tabs. Of course the options are set to restore my tabs from last time. Even the manual options to restore my previous session from the history menu are greyed out. And perhaps more bizarre of all, when I click the 'x' button to close the browser, I have to click it twice to close it - clicking it once does nothing. Firefox is the only application experiencing this odd issue.

I thought it was just my laptop and decided it was too much of a headache to worry about for now, since I rarely use that. I've been going about my business as usual on my desktop for the past few days with no issue...until I booted up my computer this morning and found the same situation. None of my tabs (and I had numerous tabs across multiple tab groups that I've been using with no problems for months!!), when I close and reopen the browser it still doesn't remember what was open when I closed it, and once again I have to click the close button twice for it to take. The 'restore session' options in the history menu are once again greyed out.

Everything else appears fine - all my add-ons are still there, and it's still recording my history when I open new pages and close the browser. It's just not restoring the tabs. This is extremely frustrating to me as someone who ALWAYS has several tabs open at any given time. At least on my desktop, Firefox says it's up to date, so that shouldn't be an issue (I thought maybe a browser update could fix it). Is there anything I can do to fix this, preferably recovering my previous sessions in the process? I lost quite a bit and I'm not too happy about that...but even if recovery is impossible, can I at least fix it so it retains my session history going forward? Any help would be greatly appreciated.

So recently my Firefox browser has been leaking memory like crazy going up to 1.7 GB in used RAM. It starts off fine when I first open it, but progressively gets worse over time, making scrolling a choppy and painful task. This started with version 28.0 but I've since upgraded to 29.0 and the problem persisted. I've done hours of research on the problem and have tried all the following solutions, to no avail:

- Turning off hardware acceleration/smooth scrolling/auto scrolling - Creating a new profile - Completely uninstalling and reinstalling Firefox - Running it in safe mode (still lagged, even in safe mode!)

Has anyone found any real solution to this problem?

As of around 1 week ago, I can no longer access facebook, any mozilla/google related page however I can still access the google search engine by entering the 197.1.1 code thing (not very pc literate).

My problem is whenever I type google.com or facebook.com into the url, nothing actually happens, the url looks like it seeking than it just revert back to whatever url I was on before. I can access youtube but the comments section is just loading but thing actually shows up. If I try to open firefox help page a new window would open but it is just blank even though I can see the see the address in the url. I can however open trouble shooting page and about firefox but none of the others page in the help option.

I have tried reverting firefox to default and restart firefox with no addon without any changes. I have tried ipconfig /flushdns and also resetting my host file from mrfixit as well as scanning for malware from malbytes, adaware and spybot and none of them made a difference at all.

I am currently using firefox 26, OS Windows 7 64bit.

Whenever I use Facebook dynamic search, Firefox stops responding. This issue also involves writing a new post/comment using the at-sign, which starts dynamic user search.

  • Before update from FF27 to FF28 it did not happen. (I use Windows 7.)
  • Safe mode does not help.
  • Clearing cache and deleting Facebook cookies does not help. Neither new profile nor clean install helps.
  • There are no crash reports within Firefox as well as no Windows error logs generated.
  • Other browsers on this computer do not have this problem, another computer with FF28 that I use works well. Firefox 28 on this computer with Ubuntu Linux works.

Edit: I got Firefox not responding even at going through conversations (messages). So I can generalize that any operation at Facebook, during which three "waiting" bars appear, can lead to the not-responding state of Firefox.
