After installing update for Windows 11 23H2, Firefox would run but could not display pages. I tried re-installing Firefox with the online installer but it can't complete the installation and no Firefox.exe can't be found. I then tried downloading and installing the offline version. The installation appears to complete but Firefox doesn't launch and Firefox.Exe can't be found in C:/Program File/Mozilla/.

Good morning, today I downloaded Debian 13 Mate version and to install Firefox I entered the following commands taken from https://support.mozilla.org/it/kb/installare-firefox-linux#w_installare-firefox-tramite-il-pacchetto-deb-per-le-distribuzioni-basate-su-debian-consigliato and the commands were


sudo install -d -m 0755 /etc/apt/keyrings

wget -q https://packages.mozilla.org/apt/repo-signing-key.gpg -O- | sudo tee /etc/apt/keyrings/packages.mozilla.org.asc > /dev/null

echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null

echo ' Package: * Pin: origin packages.mozilla.org Pin-Priority: 1000 ' | sudo tee /etc/apt/preferences.d/mozilla

sudo apt-get update && sudo apt-get install firefox firefox-l10n-it

but I get this result OpenPGP signature verification failed: https://packages.mozilla.org/apt mozilla InRelease: Sub-process /usr/bin/sqv returned an error code (1), error message is: Signature by 35BAA0B33E9EB396F59CA838C0BA5CE6DC6315A3 was created after the --not-after date.Il repository "https://packages.mozilla.org/apt mozilla InRelease" non è firmato.

What mistake could I have made? Apart from the fact that now we use sudo apt update && sudo apt install Thank you in advance for your response.

I’m trying to install the latest version of Firefox on Debian, as described at https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions. I’ve tried twice, several days apart, but both times things fail at the third step, with the fingerprint not matching. Can I do anything besides try again later? I’m using Firefox ESR, as packaged by Debian, in the meantime.

duplicate of /questions/1495342 thread

I try to install Firefox directly from the Mozilla repository.

For that, I read the article "Install Firefox on Linux" and followed the install instructions in first chapter "Debian-based distributions" step-by-step. (article https://support.mozilla.org/en-US/kb/install-firefox-linux)

Unfortunately, with every attempt to install Firefox, the Firefox LinuxMint (Ubundu) package will be still installed. The command to priorise the Mozilla repository seems to have no influenace.

How can I prevent/avoid using the LinuxMint/Ubundu repository? I wan't to install and update Firefox direct from Mozilla source.

I'm using Linux Mint 22.1 Xia base (Ubuntu 24.04 noble)

On my Lenovo Tab 11 Android tablet Android version 11. I was having problems with Firefox stalling and freezing up when opening a single web page (any web page) I uninstalled Firefox and went to the Playstore to reinstall. Android Playstore on Tab 11 no longer lists any Mozilla web browser as available? So I used another tablet with FFox and emailed playstore link. On Tab 11 Playstore will not let me install it on Lenovo Tab 11. Is there an incompatibility or is Android blocking Firefox?

Recently, I re-format my old Chromebook, then found that Firefox web browser is no longer available in Google Play(10 months ago still OK).

Also, can't install the APK in the Chromebook directly, after followed some methods via YouTube.

We would like to appeal Mozilla team, if possible, Firefox is highly available in Google Play, even the old Chromebook, PC or Android system.
