Would like to test nightly builds of Firefox - how best to get started?

I am a user of Ubuntu and interested in testing the Firefox Nightly via snapstore.

Any pointers helpful.

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?

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.

Hello Firefox team,

I downloaded firefox-142.0.tar.xz and copied the necessary files to the appropriate directories. Unfortunately, I am missing the 24x24 and 256x256 icons. Could you please add these resources?

I would be very grateful if you could help me with this.

Best regards Chris
