in some linux (arch 32 bit) I have problem executing firefox, Is there a version for CPU without request from SSE3 Flag?

thanks

I have downoloaed Firefox offline installer (a .xz file) from here:

https://download-installer.cdn.mozilla.net/pub/firefox/releases/139.0b9/linux-x86_64/en-GB/

I have also downloaded a .asc file, presumably a pgp signature.

Now both files are saved locally in my computer.

Assuming Linux latest release, how do I verify the contents of the offline installer file (.xz) from the Linux Terminal? I have install gpg tools. And commands like ```gpg``` are available.

What I did so far:

 gpg --show-keys --with-fingerprint firefox-139.0b9.tar.xz.asc

with this output:

 gpg: no valid OpenPGP data found.

Do you really want us to verify the contents of the installers you provide? A sha256 sum would be great, though not as secure, for when the GPG predictably fails for the ordinary user due to its huge and useless complexity and bureaucracy.

I have been having trouble with my Windows 11 laptop. In my efforts to resolve these issues I noticed that I now have two installs of Firefox in my Control Panel. Both installed during my time of dealing with my Windows issue. Five days apart Feb 5 and 10, 2026. Both show the same version number 147.0.3, and same size 322MB. I have used FF for many years so these seem to have been installed sometime during my efforts to repair Windows. My FF was never a part of the Windows issue AFAIK.

Anyway I have FF working as I like with my Session Manager and various AddOns and personal settings, so I do not want to have to start over with FF. So how do I choose which instance of FF to uninstall in Control Panel?

My issue with Windows was my Outlook would not connect to the server. I assume Microsoft Exchange server, my internet connectivity was fine. And FF was fne as well. I eventually was able to repair my M365 connectivity. Major PITA from out of nowhere.

No FireFox icon on desktop. How do I access the search engine? I DO have the icon for Adobe Acrobat, which I got for FREE at Firefox. When clicked on only gives Adobe site.

I use Firefox on Windows. I like it. But I also have an HP Chromrbook and I would rather use Firefox than Chrome. But I really don't want to do the entire Linux dance. Is there an easier way to get Firefox for my HP Chromebook?

I installed the msix package from Microsoft Store. We can't add our autoconfig to the msix version? We don't have access to C:\Program Files\WindowsApps\Mozilla.Firefox_xxx.x.x.x_x64__n80bbvh6b1yt2\VFS\ProgramFiles\Firefox Package Root so we can't put the needed files there. So were are we supposed to put the autoconfig files? Firefox seems to have added support for the similar situation on linux with flatpak and snap. https://bugzilla.mozilla.org/show_bug.cgi?id=1785278 There isn't a way to use autoconfig on Windows if we choose to install Firefox from the store of the OS?

I've noticed that I've got both the 32 bit (../Program Files (86)/..) and 64 bit versions (../Program Files/..) of Firefox installed on my pc. I didn't install both and both appear to be the current version. Is this normal behaviour? Only one instance appears in add/remove programs, but if I go to default apps, Firefox appears twice (presumably the 32 & 64 bit versions). If this is not normal, does anyone have a suggestion as to how to remove the 32 bit version without damaging the 64 bit one?

Noticed 3 entries for various versions of Firefox in the Windows Settings > Apps > Installed apps. There is one Firefox record in the Start menu. 1. I have unistalled all the entries through the Windows Settings, deleted all folders for Moxilla and Firefox, cleaned the registry of every mention of Mozilla or Firefox. 2. Installed newly downloaded Firefox 137.0 three days ago. 3. After today update to v. 137.0.1 - I again have 2 entries in the Settings > Apps > Installed apps: v. 137.0 and v. 137.0.1. The same problem was with Thunderbird. I also cleaned all the folders and the Registry, then fresh installed it again. Thunderbird was not updated, so I don't know if the problem has returned. Maybe something is wrong with the Mozilla installer? What should I do to have just one Mozilla Firefox entry in the Windows Settings > Apps > Installed apps after update as it was years before? (My system is: Windows 11 Pro 24H2 English US, Firefox 64-bit English US)

Additional information: I found that the Uninstall registry entries are stored in different hives: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Mozilla Firefox 137.0 (x64 en-US) HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall\Mozilla Firefox 137.0.1 (x64 en-US)
