Firefox Community Forum

I am using a mac 2018 Intel. When I upgraded from Sequoia 15.3 to 15.4 Firefox quit working. I turned the firewall off and it worked for awhile. But has not continued.

I found this reference on-line. https://support.mozilla.org/en-US/kb/firefox-blocked-macos-15-sequoia-firewall-what-you

So I am assuming some additional information may be available.

Anything new on this issue. I have been a Firefox user for multiple years. It is my primary browser.

Thank you

I received an Firefix update notification and was unable to install it desoite several attempts. I disabled my anti-virus and still not successful, worse, I lost my old Firefox browser which disappeared from laptop. I am unable to acdess the web unless I try anither browser intalled with my Windows 11 OS. I need your help please to restore Firefix in my laptop whatever version it is.

Thank you in advance.

My computer downloads your updates over and over again, tying up my computer--none of the downloads ever loads This problem is can only be fixed by pull the plug restarts as these downloads will not stop until I do this

Update 136.0.3 AND 136.0.4 - Updated, but each time the browser is closed (even after a system shut-down), it sticks with 'Being updated in another instance'. There is no other instance. Single user, Windows11-Pro, local user (not connected to one-drive or MS account). Just started this morning (27-Mar-25).

It eventually shows that it has updated, but still comes back the next time with message.

Successfully changed from 003 to 0.4, but the new 0.4 does the same thing.

Would really like to know what's going on, and fix it.

Hello, - Computer Nec Versa One P/N NNAN1700202 (32-bit) - XUbuntu 18.04.2LTS (i386), no upgrade possible to 19 LTS

- Message asking for an update of Firefox (expired root certificate, extensions disconnection) - Proposed download completed (Firefox 135.0)

- Firefox/ Help/ "About Firefox": 113.0.2 (32 bits), no update proposal - Launch the . exe file from previous download In the "About Firefox" window, version 135.0 appears well during installation When the computer is restarted, this panel has returned to version 113

The computer works normally and perfectly meets my needs (emails and internet searches), so it is out of the question to change it (it would be scandalous from an environmental point of view)

What should I do? Thank you for giving me the precise instructions on how to proceed. Sincerely, FC

For the last several updates to Firefox I receive the following NSIS Error: Error writing temporary file. Make sure your temp folder is valid. Nearly every time the update completes successfully. My disk is 90% full and perhaps that is the problem although 20 GB remain. I have run disk cleanup to remove files, especially W10 Update files. Clear Disk Info doesn't identify any problem areas (all green).

Any other likely sources of the message? Thoughts?

I recently updated my wife's computer to an Apple Mac Mini M4 running iOS 15.4. Everything seemed to be working fine including Firefox until yesterday when Firefox update box popped up. She did as she normally has for years of using Firefox and clicked the restart for update button . FF restarted and popped up with 2 dialog boxes one asking to check network for there devices which she click "Don't Allow", she only uses that computer no smart phone etc. Then a second dialog box asking for an admin login and password to install something else I put in my admin login and password clicked continue it doesn't seem to do anything except lock up Firefox to the point I have had to re-install her user from a time machine backup 2 times in 2 days. I tried installing a new copy of Firefox that will launch the issue is she's used Firefox for probably 10 yrs so there are ten years of bookmarks and logins and passwords saved in the original copy of Firefox that will no longer boot unless I do a complete user re-install from a time machine backup.

Please help, how can I fix this problem?

I have only one instance of Firefox to run.

How can I correct my installation so it does not think something else is running/updating Firefox?

Thanks,

Craig

I've been using Firefox since Windows first came out and NEVER had this problem (or any other) until about a month ago. After an update, my bookmarks sidebar failed to work. I tried to update again, but got the message "Secure Connection Failed". After many tries, I was able to load a 32 bit ( V 1390.1) which was offered from Mozilla. This despite the fact that my PC is a 64 bit machine. This 32 bit version works poorly! I've repeatedly tried to load a 64 bit version, hoping that it would work as Firefox has in the past. I am still getting the the message "Secure Connection Failed", Error Code Mozilla_pkix_error_key_pinning_failure. What is going on??? I like Firefox and I'm reluctant to change browsers, but it may become necessary. Operating systwm: windows 10. Bob N

All I have is an older windows 7 dell laptop and firefox was working ok but then it said firefox must be updated by march 14 so i clicked on the update but it has been over 24 hours and the little circle is still going around with 0 results why

Hallo zusammen,

ich kann meinen Firefox nicht mehr aufrufen, weil er wohl nicht kompatibel mit 133 ist. Es wird empfohlen zu deinstallieren und neu zu installieren. Aber dann sind meine Favoriten, Lesezeichen und Passwörter weg. Ich kann sie nicht sichern, weil ich keinen Zugriff auf die alte Version habe. Wie löse ich das Problem?

Viele Grüße Annette

Hello everyone,

I can no longer access my Firefox because it is probably not compatible with 133 (see screenshot). It is recommended to uninstall and reinstall. But then my favorites, bookmarks and passwords are gone. I can't save them because I don't have access to the old version. How do I solve the problem?

Best regards Annette

A new issue with Firefox. I download updates myself, not automatically. This morning after updating, I clicked to restart Firefox, and it restarts, but still shows that it needs to restart. Even after multiple attempts. How to resolve? Thanks
