Firefox Support Forum

Fire Fox no longer appears on the menu bar. I have to go to programs and open it each time I want to use Fire Fox. It will appear on the menu bar as long as I have it open but leaves the bar if I close it.

Hours after exiting firefox, the application continues to run processes and hold on to the memory it was using when I exited the application. The only way to free the memory is to key the processes via Task Manager

In the past week or so, Firefox has unexpectedly "frozen" and does not respond. I have not loaded any new programs during this period. The only way I can get Firefox to run is to end all the Firefox processes in Task Manager and restart it. I also noticed that there are usually 9 firefox processes running in Task Manager.

Hi. I've been having this problem with my iMac for sometime, but now it's affecting my Macbook Pro, as well. Both machines are 2015, running OS 10.15.7.

They have problems loading webfonts (I get the annoying question marks). I tried creating a new test user, and the issue persisted. Any ideas on what I should do?

Thanks!

Hi My browser updated to latest version 100.0.1 but all my opened tabs are missing. And what is more important all my sync bookmarks are also gone. I can note restore any of sync data.

Is Firefox will support this feature ? Or at which version will support ?

File System Access API

My picture-in-picture remains in full screen, even if I double click with my mouse. When I click the ESC button it just closes completely. I have restarted both Firefox and my computer, but I keep getting the same problem. Not just in YouTube either, also on other websites.

I have tried to get help regarding the 2 problems that I feel are related. I use Norton as my security system, they say that Firefox is up to day. When I try to start Firefox it takes two or three times clicking on the icon before it stays open. Then when I need to open a new tab to go to a website that I have opened a hundred times, sometimes it will not even open the website and other times it will open but not let me sign in. On the sign in page to error this morning said: Bad Request - "Your browser sent a request that this server could not understand. Size of request header field exceeds server limit."

It will often just say it can't start that page, try again.

The "try again" has been going on for awhile, the Bad Request is new. Please help me with this problem! It is beginning to get annoying.

Thanks for your help. [email and phone# removed from public view]

I could not pay my bills at handelsbanken.se today... so they adviced me to try another browser and I had to use Edge for the first time ever... and that worked. Why coud I not pay my bills with firefox as usual?

Since updating to Firefox 100.0.1 cannot print any web pages. Cannot print to a printer, or to FoxIt pdf printer. Printing in MS Edge works with no problems. I have cleared saved print settings - did not fix problem. Please advise. Thank you.

Hello, I recently migrated to a new MAC and now when I download a file and click on "show all downloads", it opens the about:downloads tab and not the downloads list from the library. Is there any way to force Firefox to open the Library when I click on see all download please? Thanks

I can no longer print from firefox. The final print always comes out 1/5 +- size and is unreadable. It doesnt matter what king of a document it is and if I go to chrome or edge it prints fine. This began occurring I believe after the last version.

Up to today if I click on a link in Outlook email it would open in Firefox (both set as default) If I change browser default to Chrome, links work. I'm at latest update in Firefox. If I right click on email link, copy, paste into Firefox, links work OK. Mouse icon will spin for a few seconds and there are no error messages. Not aware of any changes. Restarts of PC, Outlook, and Firefox (even tried troubleshoot mode) = no help.
