Firefox Community Forum

bold text I am booting up an older Windows 7 tower computer and wish to know how to update both Firefox and Thunderbird? The update popup seems to be stuck in download phase.

Hello,

When I attempt to open Firefox, I am getting a pop-up screen saying:

135.0.1 not compatible with min version >= 135.0 max version <=135.0

Also, I am being advised to reinstall Firefox. Do I need to uninstall Firefox first?

Windows10, Dell Laptop

Thank you,

I read there is a need to immediately update Firefox. I down;loaded it, but got a message that a newer version exists...? Also, it shows my latest update was 11/24. I use auto updates and recall one much more recently.(in fact I found the new tabs annoying) I am perplexed.

I'm running Firefox 139.0.1 on Mac Sonoma 14.7.1.

Since FF V138, I've had this extremely frustrating problem where, approximately once a day and while the application is still running, Firefox seems to either auto-revert to an older version' 'or otherwise mess up the installation files. I don't get any notice this is happening until I try to open a new tab and it brings up the "You must restart Firefox" notice. When I click Restart, it pops up with "You've launched an older version of Firefox, so you won't keep any of your bookmarks because that would be unstable" error.

The only way I've found to fix it is to redownload the most recent install files, which, after the fresh install, will allow me to keep using Firefox with my bookmarks for the next 5-6 hours, before the whole process starts again.

I theoretically have auto-updates off; my settings are set to the other option, "Check for updates but let you choose to install them". Doesn't seem to make a difference. It only does this on my Mac; the FF install on my Windows machine works fine.

I really want to keep using FF. It's my preferred personal browser. But this is really messing with me! I was hopeful that 139.1 would fix it but same issue, so far.

Help! All my bookmarks have disappeared from the Firefox browser. I believe there has been a browser update done by Firefox. I found various ways to recover bookmarks and found a folder named 'old Firefox Data' on my desktop. But all files I try to import give me an error message stating that this file doesn't contain any bookmark data. I tried to import bookmark files and favicons.sqlite files. No luck. I now cannot access bookmarks accumulated for about 10 years. Really need to get them back into this new browser. Any advice highly appreciated.

Good Morning! :)

I have a note book HP, which windows operating system was erased back in the past, I happily use mozilla. This device I use it exclusively as a monitor to watch TV.

I got the notification of the Mozilla update, I have downloaded many times in the laptop: firefox-136.0.1-tar.xz However does not run or execute the file and update the system and laptop. I am able to open the file, but that is all.

Please let me know what I am doing wrong to fix it.

Thank you very much for your attention

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

After the last update a couple days ago Firefox does not come up correctly. Search doesn't work. Duck Duck Go seems to be the default search engine and Google is missing from the selection list when the left mouse button is pushed. I really don't know how to describe the problem. It does come up in troubleshoot mode more-or-less correctly. Something odd happened during the update. A screen came up with some sort of message about having run into some sort of odd problem and that it would have to stop and restart the process, which it did. Hasn't worked properly since.

So I know this question has been asked and answered in various scenarios but so far I've not found one matching mine.

Personal PC. I'm on V 131.0.2 since a reinstall last year but only now realised no updates have been done since because of this msg. I've worked through the various fixes others used re policies, but I can't locate any policy files in the various locations suggested; registry editor (HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox key (don't have it) & others, about:config (nothing showing on a search), Program Files/Policies (don't have it), C:\Program Files\Mozilla Firefox\Distribution folder (don't have it). So I could not find the offending poicy DisableAppUpdate anywhere in locations offered by other posters etc.

Rather than taking forever to pin down the culprit, can I not just manually update to the latest version or will that delete all my settings/extensions etc?? Given how often it's crashing I'm almost tempted down that road except that I like to have my History intact as I often want to find a site I've not bookmarked.

Thanks.

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
