Just bought a new iMac. Firefox will not run on it. Any attempts to dump and reload have failed. Apparently the software does not ask for permission to access the network. Is this something that will be fixed soon, maybe it's something to do with Apple? Anyway, should I try to download an older version of Firefox? Firefox is my preferred browser. I don't want to be forced to use another.

Hi, I want to move my FF profile(bookmarks, passwords, login in's, CC info, preferences, etc) from my old computer to my new computer. I did a quick google search and found all I have to do is it copy the Appdata/roaming/mozilla/profile directory to the new computer. I had closed FF on the old system before I copied it to a USB drive. On the new computer I installed FF. opened it, closed it, copied the file/directory to the new system. There were already to profile subdirectories present. I just added mine. Now FF crashes. I can't have both computers on at the same time so I do not think 'Sync' will work. What did I do wrong? Any help would be appreciated.

Multiple installs of Firefox - how to tell which is safe to remove (not being used).

I need to reclaim space on my hard drive so I was looking for apps to remove. I noticed that I have two installs of FIrefox. One is listed as "Mozilla Firefox (x64 en-US) (261MB) (2/7/2026)"; in the description area (when you expand the app panel) it says "135.0"; the "Modify" button is grayed out - all I can do is click "uninstall". The other install is listed as "Mozilla Firefox 72.0.2 (x64 en-US) (188MB) (2/23/2024)"; in its description area is lists the version again "72.0.2"; the "Modify" button for it is also grayed out - I can only uninstall.

How do I tell, from the Firefox that I launch from my taskbar or start menu, which one I'm running and which install I can remove?

I'm on a Windows 10 Lenovo Flex 3 laptop.

I received a message from Mozilla saying i had to update my version of firefox or certificates would be invalid and things would run slowly or worse. The deadline was today so I followed the update instructions, installing the update. Then all my tabs crashed (over 100) in 7 active windows AND the Restore crashed tabs button did nothing either for individual tabs or the restore all tabs button.

Helllllp? Please.

I want to update Firefox but also version Firefox-134 causes the same problem as all previous versions newer than Firefox-95: GUI is not started in my Linux system despite all the requirements noted on the Mozilla pages with the release are satisfied. Basing on that I have read and experimented as well as on response to my bug report, https://bugzilla.mozilla.org/show_bug.cgi?id=1938497 I suppose that the new versions of Firefox are not able to start GUI using libGL backend GLX and they require LibGL backend EGL only. This requires libEGL version and other associated libraries that are present only in newest versions of Linux distributions like Fedora-41. These new versions are for new hardware and it is pointless to install them on older hardware because they would work probably ineffectively and cause problems. Linux is very customizable and users introduce adjustments and install software created by themselves, for years. That is why an update to radically new version of the Linux distribution is justified after buying a new computer. This would be required for making the Firefox-134 binary provided to run with GUI as well as for possible compiling it from source.

That is why I would like to ask for consideretion of submitting a new version of Firefox binary statically linked (at least the libraries that are required for GUI) so that it will work with GUI on older Linux systems obeying the requirements noted on mozilla pages with Firefox releases, assuming 4-8 GB RAM is available.

In the beginning of January 2025 I have had to set a virtual machine on my host Fedora 20 with Live-Fedora-41 that contained Firefox-131 upadted subsequently to Firefox-134. This way I can use Firefox-134 but having 8 GB RAM that is maximal value of RAM allowed by my computer I had to declare only 4 GB for the virtual machine to enable host Fedora-20 to work normally. However, the 4 GB of RAM is actually a minimum required for effective using of the new versions of Firefox and additionaly, 20 GB of disk space for the virtual machine had to be reserved.

This solution is far not optimal, the VM is mainly for test purposes. Therefore I remain my suggestion noted to above.

I kindly ask all NOT to place here irrelevant, nontechnical comments like the three below from one user; they have their place in general social media.

Hello there, Firefox for Linux aarch64 has been supported for a while in nightly version. I wonder if that will move to beta or maybe stable release of Firefox? AARCH64 SBCs, comuter or laptops are becoming in current years. I just want to ask if there is a plan from Mozilla to add aarch64 architecture support in Linux for stable release?

Thank you
