Firefox Support Forum

With every update, Firefox becomes more and more unusable. It's been 20 minutes so far on this morning's session, but the tab won't open. And Options won't let me clear data as those tabs are dark. It's hard to be nice when I read these same complaints in forums all over the internet. It's only getting worse, and the recommendations are always the same -- clear your cache, remove extensions, blah, blah, blah. No, nothing works! It's time to blow it up and start over. Not to mention that it's always crashing or not responding. It's just about as useless as Edge and Chrome. What a pity. (Oh, I just noticed -- 27 minutes later -- that the Clear Cache tab is now active. Better late than never, I suppose.)

I re-installed Firefox (I had it installed previously) but it won't load any pages. Like nothing. I have Windows 10 (HP laptop). I'd appreciate help troubleshooting this so I can get it working.

For some reason all my toolbar bookmarks have disappeared from the toolbar line below the search box. View Bookmarks Toolbar is checked 'Always Show'. I tried customizing and restoring defaults but still don't show, although the toolbar line disappeared and option was changed from Always Show to 'Only Show In New Tab'

I am using Private Browsing, although it does same even if I don't. So frustrating

What happened? Was a new version released 4/12/2021?

This is really getting annoying. Again the 4k and 8k videos on Youtube are stutturing, saw some some improvement with Firefox 87 at least on the 4k videos. For example this video in 8k does not work at all, audio works fine and it stutters totally showing a single different frame every 10 secs. https://www.youtube.com/watch?v=5LxsViMm25o&t=54s&ab_channel=AroundTheWorld4K . My pc is running Win 10 64-bit, 8gb of ram and all with all drivers\os up to date. As usual no issue with Google Chrome while reproducing the above video in 8k.

CPU Intel(R) Core(TM) i5-2400S CPU @ 2.50GHz 4 Cores GPU - AMD Radeon R7 200 Series with 2gb.

Pls fix.

Im really lost... Tried to delete in safe mode and after i uninstalled firefox. No chance!

Any advice?

When I try to open Firefox on Debian Linux I get an XPCOM error XPCOMGlueLoad error for file /mnt/chromeos/removable/plus_slim/dev/linux/packages/firefox-87.0/firefox/libxul.so: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory Couldn't load XPCOM.

I included a screenshot of the message and my firefox file directory

The problems I've had with Firefox keep growing. First it was PNC Bank, then Unite Airlines, and now Winter Park Resort. Operating in Safe Mode long term is not an option. After years of using Firefox as my default browser it is no longer worth the hassle. Moving to Safari. If you all ever fix these issues let me know, and I will return. Thank you for your time and attention, Andy

My tabs are constantly - several times a day, every day - crashing. I'm not watching any videos, I've tried a clean (deleted profile folder) install, and turning off hardware acceleration. It's not anything attached to my profile, as I sync with a 2nd computer that has zero crash issues.

Dear all,

I am planning a move towards the Firefox ESR 78.6.x. Currently my customer is using the Firefox Rapid Release 84.x and need your help with the profile migration. The customer has a very isolated on-premises environment and does not allow the users to login into a Firefox-Account. Therefore the settings for Cookies, Cache, History and especially Bookmarks are not synched.

Environment details:

• Enterprise environment with several tausends of clients
• All clients on Windows 10 Enterprise between 1809 and 20H2
• All clients have always the newest Firefox installed currently 84.x

This creates a huge challenge to sync this stuff. Therefore I have now identified the following two options:

1. 1 Allow the downgrade by using the environment variable MOZ_ALLOW_DOWNGRADE on Windows. For this option I am trying to find the real reason why this "Downgrade-Stop" has been implemented in the first place? What risks in detail do I take to allow this downgrade? Has anybody done this before and do you mind to share your experience here? How many issues did you face and how did you remediate the issues?

1. 2 Hand over the migration to the users. Copy their current profile to their desktop and ask them to import their bookmarks manually. Not preferred by users and I can't even blame them for.

Is there any other way to automatically sync the profiles from 84.x to ESR 78.6.x without user interaction?

Thanks in advance Amir

I have noticed that if I leave an empty firefox tab open after sometime the empty tab somehow would start using a large amount of RAM. I don't know if it is expected behaviour or not. I came to know about this problem as I use a laptop and I very rarely put it to sleep, so my laptop would idle out on charging with a empty firefox tab open and it would start out with consuming reasonable amount of RAM but after I return mabye after 20 minutes and the RAM usage would skyrocket to about a gig for only firefox with that empty tab. I do have 4 add-ons installed but firefox behaves the same when I restart it in safe mode. Any help is very much appreciated.

I unstalled my old Firefox version without saving my bookmarks. I then installed the current Firefox version and realized that all my bookmarks are gone. I tried already to restore them, it finds the file, but then I cannot import them. The c:\windows.old thing does not work for me. Any other ideas where to look for my old bookmarks? Thanks, Daniela

Apparently Mozilla did an update and not it defaults to it's own printer dialog box. I hate it. There is a link to use the system print dialog box but it only works for that specific print job. I can't find a setting to force Firefox to always use the system printer dialog box. Anyone know how to fix this? It's enough to make me stop using the browser becasue thr Firefox dialog box sucks.

Called Wells Fargo and they told me to disable all password managers in order to log in!! WHAT???? I can get to my account using Edge WITHOUT LastPass, but something in 87 is wonky. Spouse has Firefox 86 with LastPass and he can get on with no trouble. Have started a trouble ticket with LastPass and will be contacting Wells Fargo tech support for their input. Please fix!!!!!

I have more than 100 tabs and more than 1k open in the background (the tab is downloaded from the previous session, but not open). When opening / closing the FF tabs, it gradually uses up to 18-20GB. When this limit is reached, friezes begin, the tabs open slowly. Memory busy FF is released ~2GB, after that it starts to load pages. According to symptoms, it looks like a shortage of RAM. But I have 64GB RAM, reserve (Win) 17GB, free 15GB. And more is 9GB SWOP on SSD, 136GB of free space on SSD and 1TB+ free space on HDD (RAID0), 200+ MB / sec internet . Where and what to change to ff used accessible resources? After all, they exist!

Typing the problem in the quote marks in the search box yields over 400 identical questions. So obviously this is a known problem with FF, and hopefully with Mozilla.

With me it happens on Facebook. Clicking "wait" basically does nothing, clicking "stop it" it basically stops the page from loading, so you can't post a message or have any interaction with the site whatsoever.

All along I'm watching the CPU at a constant 50%-60%, and memory for one tab of FB going up steadily from 400 MB to 1.2 GB (almost like a memory leak).

Now, my laptop has really limited specs, 3 GB RAM, Win 7, 10 years old. So I thought the laptop is probably to blame. Till I did the following experiment: Let's try Edge, with the exact same tabs, exact same sites.

So, one tab of the same FB page + one tab of Yahoo Mail -> FF: 60% of CPU, 1.5 GB of memory (and counting). Edge: 10%-15% of CPU, 500-600 MB of memory, and FB smooth as silk.

Any suggestions/solutions are welcome.

When i click on the google maps icon (google uk home page>dots in top right hand conrner>google maps icon)or type google maps into the search field then click on the google maps link I end up on the Sheffield Hallam University log in page (a bookmark from a while ago). This has started happening in the last few weeks.

If I use Edge then everything happens as expected and google maps opens.

I have tried refreshing firefox and disabling add-ons, neither works.

Using Windows 10 home V20H2, upto date firefox.
