Heads up for custom installs: running tbird and firefox on linux, I install both in my home directory for my own ease of updates and portability. I get releases from https://ftp.mozilla.org/pub/ in tarball formats which install in 30 seconds. I recently ran into a problem which I've not seen before. recent d/l of firefox-136.0.tar.xz for linux-x86_64. It crashed immediately with err 126. The ff.exe and ff.bin files were for ARM arch. This wasn't easy to locate and I think it was caught but anyone still headscratching may want to see if this is an issue - I had a good 136 on a laptop and overwrote bad install on desktop.

Thank you for considering a new feature. However, this feature of a new sidebar is in the way on my screen. I have it setup for use in a very specific way. Adding a sidebar that I cannot turn off without going into "about:config" is a very bad idea. It made a mess of my space. Yes, even that 1/2 inch of space messed up my spacing. Please ask in the future before making any changes that alter the size and width of my screen space. It's already jammed for work.

I saw an option for donations here. If you ask before making anything that alters the screen layout, I'd be willing to make a donation. But this was just upsetting and has stolen over 20 minutes of my work day. I don't have that kind of time, especially with my colleague out on medical leave for possibly months.

1. I downloaded the latest Firefox from Mozilla official website, installed the app, made sure I can see the Firefox app in my applications. I start using the app. 2. Everything will be fine for a few days (say 1 week or 10 days) and one fine day, the browser stops working. Even google.com doesn't open. 3. I quit Firefox and try to re-start it. I cannot find Firefox in my system. It just disappeared. I cannot find in my applications. The search doesn't show Firefox.

I re-install by going back to step #1

This has happened not one time but many times. I searched if others have this issue but did not find anything that i could use. Hence posting this question here.

I have Firefox installed on a lot of other Macbook pros in my home, no other system has this issue. I don'ty understand what is happening. Just wanted to get some guidance in resolving this issue.

Thanks _Krishna

Have an old computer and running Ubuntu

Want to keep Firefox but old man and don’t understand certain aspects

Could somebody email me a link that help? Is there such an animal?

That is the first line in the Hippocratic Oath. All doctors have to swear to it. All software developers should too.

I made the mistake of letting Firefox on KUbuntu update. It obliterated all my tabs and all my history. There's nothing left. I had a lot of tabs open with intent to use them to update some astronomy instructional activities. I don't know if I'll be able to find them again.

I don't really have a question except to ask: What fresh hell is this? Is it really that hard to just leave things the hell alone? I'm afraid to ever update Firefox again. If everything else wasn't based on Chromium, I'd be out of here.

Also, it looks like something out of Windows 7.

It's all gone. It's a wonder you didn't delete all my bookmarks while you were at it.

Please indulge this silly question. What possible benefit is there for Mozilla continuing to list this page with the very first, oldest Firefox release at the the top, requiring the user, every time they visit, to scroll to the middle of the page to search out the current latest version instead of having the chronological order from latest to oldest instead?

After upgrading Firefox, i cannot connect to internet. My internet is working fine, but none of the websites can connect. I restarted Firefox twice. I restarted my laptop (windows11), can you help me? Email removed for privacy

I have just completed a new installation of Ubuntu 22.04 and opened Firefox. On the Settings page, I'm seeing a message that says, "Your browser is being managed by your organization." My device is a personal home desktop not connected with any organization. Why am I seeing this message on a brand new installation?

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 CANNOT find a way to restore Cut/copy/paste, Zoom, and numerous other toolbar items since your last night's updates. Please make it possible to easily restore, and impossible to remove through updating..

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.

Ever since a few weeks ago, some of my add-ons as well as every new add-on I added after that are unavailable at the start of Firefox. I then have to click into the application menu, click on the warning message for that add-on and enable it again. Since this is quite tedious and frustrating, I tried looking online for any info. I tried updating everything, disabling and enabling manually and removed and re-added some if the add-ons that cause issues.

I am loath to set up a fresh profile or reset all add-ons as that would cost a lot of time to configure everything again. In hopes of a solution that avoids that I am asking here now.
