Firefox Community Forum

I want to re-install Firefox after having re-installed Windows 11. But the installation keeps freezing or I get a message that it's already installed and just needs to be refreshed, which doesn't work either. I tried removing the Mozilla program files from File Explorer but that froze at 99% complete, although the files did show in the Recycle Bin. I definitely need help.

Trying to install Firefox (even though the icon is on my dektop at the left) it keeps askiing for authentication ,I have tried entering different passwords, but there seems to be no link if one has forgotten a password. Will this be updated?

Trying to install Firefox through ChromeOS Linux from the official Mozilla Page. I'm following all the steps, but the terminal is telling me that the key is missing and there is no PGP data available for it. If anybody could help me out, I'd really appreciate it. I attached a screenshot of the code when I try to install it.

firefox set up won't load. I have completed all of the required steps but I am still being asked to finish the set up. Anybody else have this issue? If so what do I do?

google blocking Firefox download. What do I do? When I open the downloaded browser app icon from Google store the browser changes to Google and Firefox is not in the drop down list either.

I can't get my Firefox icon to go to my desktop and become active. I also cannot uninstall Mozilla - it just allows me to attempt to repair it. My icon also shows Firefox 2 for some reason.

Win10 desktop: Boot-up forces selecting Firefox as default, then goes to default apps screen. Selections are correct. No save function (thought they auto-saved) . Then have two Firefox icons on taskbar: first is far left (normal) select and calendar & email launch. The second Firefox icon is far right on taskbar: Select and the system repeats the select browser & default apps Shown in the first line above.

Resolved Update: apparently cat cannot write to /etc. Resolved by using:

sudo tee /etc/apt/sources.list.d/mozilla.sources <<eof types: deb uris: https: packages.mozilla.org apt suites: mozilla components: main signed-by: etc keyrings packages.mozilla.org.asc eof p></eof>

The instructions need updating!

_________________original problem (in case some one else needs the information)

I am following the instructions in section "Install Firefox from Mozilla Repository (Recommended)" at https://support.mozilla.org/en-US/kb/run-firefox-chromeos At step 4 I am receiving a permission denied error: "-bash: /etc/apt/sources.list.d/mozilla.sources: Permission denied" I am not sure how to resolve or continue.

Last command and output:

username@penguin:~ cat <<EOF > /etc/apt/sources.list.d/mozilla.sources Types: deb URIs: https://packages.mozilla.org/apt Suites: mozilla Components: main Signed-By: /etc/apt/keyrings/packages.mozilla.org.asc EOF -bash: /etc/apt/sources.list.d/mozilla.sources: Permission denied

I followed the advise and removed all the profiles from my laptop. (Copies are on an external hard drive.) And I used the download file from the Mozilla community site which is 490 KB versus the 375 KB download file from firefox.com just in case the smaller file was corrupted. But I still got the Profile Missing error message.

I am trying to simulate a laptop that has never used Firefox and so can't say that "Your Firefox profile cannot be loaded.  It may be missing or inaccessible."  I uninstalled Firefox using the Installed Apps page. Can there be fragments of Firefox that I need to hunt down and remove? I also removed the Old Firefox Data folder from the desktop.

How can I successfully install Firefox? Then I will use my old profiles that contain all my bookmarks.
