Every now and then (maybe once a week on average), Firefox suddenly freezes, and checking 'top' shows that the plugin-container is using 90%+ of both CPU and RAM (I have 12 GB of RAM). So I kill firefox, and when I restart, it is running as normal again.

For extensions, I only have LeechBlock (and Ubuntu Modifications). For plugins I have Flash, Java, OpenH264 Video Codec, and iTunes application detector (apparently). Flash and Java are both up-to-date.


Since the problem happens somewhat rarely, I haven't been able to reproduce it or track down any kind of cause, but I thought it merited reporting anyway; a web search didn't seem to show anyone else reporting the same problem.

I was looking at images in an email, (PDF) and firefox was running 339,600K and froze my system. Is this typical? It just kept happening I waited, however the screen turned gray (with the email showing beneath) and after about 15 min I decided that was long enough and refreshed the browser (or the little circle arrow). Then I was able to begin again, but it kept happening about every third image. Thanks in advance for your advise

If I click on a blank field no cursor appears. If I click on another window eg. a safari window and then come back to firefox, the cursor is now in the field I clicked on. Then I type in e.g. a dollar amount, but no numbers appear then I go to safari and comeback to firefox and the numbers are there. Then I try to scroll down using my trackpad and nothing moves then go to safari and come back and the screen has scrolled. The same happens if I go to another window e.g. open office and then return. This began after installing el capitan. At first I may have had a lack of RAM, but I have taken care of this. Ideas? Is there any way to reinstall Firefox completely, preferably without losing my bookmarks to see if this helps? I'm on version 43.0.2.

Dear all,

The problem: I am accessing a webmail server (Outlook) located at a British university. Either when I log in or log out there, Firefox stops responding. I have to close the window and then restore the session to get my tabs back (which has led me to open very few tabs these days).

The diagnosis: I thought it might be malware, especially because sometimes tabs opened with the name "prosperent", but were not fully loaded. I think whenever I used CCleaner just before logging in, the log in was smooth.

Attempted fixes: - First of all, I reset Firefox internally - to no avail. - Next, I uninstalled and reinstalled Firefox, but the settings were remembered for some reason. So I uninstalled again, deleted all personal Firefox setting folders and reinstalled it again. Firefox was now pure in start mode - the problem persisted. - Then, I installed a malware programme to check for hidden viruses in addition to my normal anti-virus programme. The malware programme found a few cookies and deleted - the problem persisted.

I would be happy to know what else you might recommend here.

Best wishes, Matt

I had been having problems with firefox since a few months ago. When I opened it, it worked really good, but two or three hours later it got reeeally slow, and when checking the Windows Task Manager it said that Firefox was using about 2.5 RAM GB and I had to restart Firefox. The real problem started when I got sick of the previous issue and tried to fix it. and what kind of fixed that problem was refreshing Firefox (reinstall it didn't worked and I say "kind of fixed it" because only made the problem to take a bit longer).

I was so happy that I got like 5 hours on Firefox but then it got slow again and tried to restart it but... Firefox didn't do anything, just kind of freezd in the start (see image below). In this stage, won't even try to load anything, if I type an address and press enter, it won’t do anything, I can open the menu and open tabs, windows and private windows but all of them are the same. The only way to close firefox is by this menu (the X button in the top right corner doesn’t work). I can’t even load the add-ons page, nor the settings page. I have access to the help menu to refresh firefox but that fixes the problem only for one session (if I close and/or restart firefox, the problem returns).

I tried all what is said here: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems but didn’t work or worked just for one session (reinstall, refresh and new profile solutions work for a single session, but the problem with the RAM persists, doesn't even work with safe mode).

I tried the solution given here: https://support.mozilla.org/en-US/questions/1021896 but won’t work not even for a single session. I neeeeeed help! Thanks!
