64 & 32 bit versions appearing on pc

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?

How to verify offline Firefox installer using its .asc file

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.

Why can't I install Firefox on my firestick? I use it on all of my other devices and it's what I'm used to using.

ESR for Win 7

I have Firefox 115.0.3 on my Win 7 32bit. Do I still have to download the ESR or is 115.0.3 still in the okay range of 115?
