Firefox 87.0 (64-bit) on Ubuntu 20.10 is currently unusable as it won't open anything.

• Firefox opens with no page loaded.
• Clicking the single "getting started" bookmark does nothing.
• Entering a search term in the address bar and pressing 'enter' changes the url in the address bar but nothing is loaded and the page remains blank. There is no indication that anything is loading.
• Entering a url, such as "www.youtube.com", and pressing "enter" does nothing. There is no indication that anything is loading.
• Opening the menu by clicking on the burger icon, then on "preferences" does nothing except make the menu disappear (same with most of the options in the menu).

In the browser console I see some errors and no request info (see screenshot).

I've tried `sudo apt purge firefox` then installing again, which didn't help. The problem started with ubuntu 20.04 (I only updated to 20.10 to see if it might resolve this problem).

I've tried the "refresh firefox" option, starting in safe mode, and clearing the startup cache, which didn't help.

Any suggestions would be much appreciated.

Hello all, after reinstallation my Firefox 88.0.1 on Windows 10 64 Bit does not go online. I can't open the settings. Other browsers like Opera and Edge are ok on the computer. Does anybody have any hints ? Many thanks, Volker

(SECOND occurrence of this problem; not sure HOW previous instance resolved - my short-term memory ISN'T the best at present!)

Have taken all recommended steps short of completely refreshing (renamed a file titled 'config.json.old' as it was the ONLY one with a 'json' filepath suffix) because I don't want to have to relocate (another) existing session / configured profile by trial & error if avoidable - 'cookies' were removed along with history / cache cleared; reset / deleted related browser registry entries as directed, activated ' Troubleshooting / Safe Mode' contingency and STILL can't download anything (additionally, tried to do so with and without limited-time Malwarebytes web protections).....want to CONTINUE using Version 95 because by ALL indications and from what I'm seeing in Comments, my instincts about newer ones - were sound, WELL-informed.....please advise ASAP? Thanks!

After having installed the latest Firefox update Firefox starts but it does not react to any link inserted for display.

If have tried all three help solutions provided but it does not react, also a new installation changed nothing

The error message is: Starter process deactivated after error.

Could someone please help to make run it again

P.S. It was not possible to get the Troubleshooting information as I could not write this request on Firefox but had to use another browser

After closing firefox, 6 instances of the process keep running consuming 50% of the CPU (snapshot attached).

I haven´t any issues to restart firefox, however I have to kill the processes manually in order to completely close it.

I am using Windows 7.

Regards

Over the last couple of days we are seeing instances of Firefox just disappearing from Windows 10 and just today from a Windows 7 pc. When I say disappears, the desktop shortcut becomes dead, click on it and a prompt to search for firefox.exe comes up. Checking Add / Remove programs shows Firefox to be installed. Checking C:\Program Files\Mozilla Firefox reveals empty folders with the exception of a couple of text files. Trying to reinstall the Firefox app, we are prompted with a message that Firefox.exe can't be found, and there is a button to browse for it. The only solution we have found for this is to copy the C:\Program Files\Mozilla Firefox folder from a working pc, and we just received a call from a user we did this for telling us that it is gone again. Any ideas?

Thanks.....

We have checked for viruses.

FIX what seem to be CLEAR conflicts with relationship between platform and user's device (desktop, Dell Optiplex 790 in my case - that do NOT occur with Opera, otherwise) as WELL as aforementioned ATROCIOUS performance quality - BTW, this is the SECOND update / upgrade I've done in LESS than a WEEK.....

All of a sudden Firefox has ceased to react when I'm trying to download a file/save a page. When I click Cmd+S or File → Save page as…, nothing happens. When I try to open an upload dialogue, a solid gray window appears, and that's it. Uploading files through drag&drop interface works fine.

The problem seemingly appeared after migrating from a Mac Mini to a Macbook Air (both M1). I've already tried to restart the laptop and refresh Firefox — to no avail.

Is there anything else I could try to do?

Hi there,

I have a brand new Win 10 MS Surface 4 Laptop, and have tried downloading and installing various versions of Firefox:

From the the Windows Store Direct downloads (via MS Edge): Mozilla FF Win 64 Mozilla FF Win 64 MSI Mozilla FF Win 32

I have completely uninstalled and attempted to re-install each in turn. Attempts to open FF through desktop shortcut, Start Menu and Win-R FF.exe all seem to start but only ever get the briefest flash of a blue line along the Taskbar then nothing. Same happens starting Shift-Shortcut.

Nothing shows in Task Manager either after any start method. I'm pretty sure I'm not in 'S Mode' as I've been able to download, install and run WhatsApp Web, but I'm not wholly convinced I've cleared that up fully.

Thanks! E

I work on computers without admin rights, and i can't install add-ons,

how to make a true portable Firefox without using registry at all

I really don't understand that a free software allows such a blocking, even if chrome doesn't pose any problem with add-ons.

is there a way to lanuch firefox with a option to not use registry or to redirect registry in file or in a not locked custom registry like

hkey_local_machine/software/policies/Mozilla_portable/Firefox

or something like that ?

I HAVE COMPLAINED BEFORE ABOUT THIS- \bing-ebay-google-wikipedia-amazon - CONSTANTLY -- DOWNLOADING ONTO MY FIREFOX - AND I DID REMOVE ANY THING CLOSE TO bing-ebay-google-wikipedia-amazon- I NOTICE SEVERAL PEOPLE ARE COMPLAINING ABOUT THIS PROBLEM- SO REMOVE THAT CRAP ADS OR I'LL FILE A FORMAL COMPLAINT- I WILL MAKE SURE THAT PEOPLE SEARCH THEIR FIRE FOX. THANK GOD FOE UNINSTALL TOOLS THAT CAN TRACK AND FIND YOUR SECRET AD ONS- NO ONE SHOULD HAVE TO SEARCH OR WORRY ABOUT FIREFOX PUTTING JUNK ON THEIR BROWSER- YOUR STATEMENT OF TRUST STATES THAT FIREFOX WILL NOT AD JUNK OR UNWANTED ADS.

latest version 88.0b6 still gives "can't load xpcom" message why is this still happening after 3 years of the problem in the history of upgrades. Don't tell me to check profile as I can't even start FF. I have done all the deletions as instructed by various experts but still get the message "can't load xpcom". Samuel Santos said download "83" to see if that fixes it I don't know if it did cause I then got "CAN'T FIND ENTRY POINT"

I need to reload Firefox from a disk image after every reboot on my mac. This doesn't take much time but its an exercise after every boot up...Need to run the image, punch in credentials and then wait for the sync-up to see all the browsing history and bookmarks...Is there a fix to resolve this challenge?

hello since update of newtest version of firefox 89.0 (64-Bit) the browser is freeze and i receive message "do you will wait or close the browser". When i press wait so the windows is reload and ask if i will do wait or close firefox. I have only possibility to close firefox. The problem is all time.

My System: Ubuntu 18.04.5 LTS with 89.0 (64-Bit) Firefox.

Hi there, I've downloaded Firefox but I only seem to have the disc image, how to I get the app to open? It's in my applications file. I have a MacBook Pro with High Sierra version 10.13.6 OS. Many thanks in advance. Best regards, Anna Daley

I just recently updated my Macbook Air to Big Sur and downloaded Firefox to use as my default browser. Installation went smoothly and I am able to use the program as intended. When I click on an external link, an window pops up and tells I do not have permission to open the app and to contact my computer or network administrator for support.

I am not computer savvy when it comes to programming and would love any help anyone has to offer.

Most appreciative.

Hi All! Need some help for a client please :) iMac 27in (late 2013) Processor = 3.2Ghz Quad Core Intel Core i5 Memory = 8GB DDR3 MacOS Catalina = 10.15.7 1TB HDD Not sure if this is a MacOS thing or a Firefox thing. My client would prefer to use Firefox, currently using Chrome. However - whenever they close Chrome or shutdown / restart the computer, Firefox looses everything and they have to re-import all the data from Chrome. This is happening on a continual basis. It's simply not saving any data / settings that are imported from Chrome.

Thanks!
