Firefox Community Forum

Hi Team, Hope you are doing well. I am not able to install firefox on my win 11 laptop Because of the error shown below. I tried to delete all temp files, I also, restarted my laptop several times and I did the scan to check corrupted files too. Please advice on the further steps.

Thank you.

i have payed ma donation for Firexfox and reached to upload a Window 10 version but was unable to install it because it was a 64 bit and my pc is 32 bit.

May i be refund or can you send me the 32 bit version ?

Cordially.

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.

my firefox keeps getting completely deleted from my system after repeatedly reinstalling and having it get delited from my windows 11 system i installed with administrator permission and the installation lasted for two days now this morning after working for about an hour it crashed twice on the third attempt to open it i found that it had been deleted what do reckon i do

I am installing Firefox (Latest from website) on a windows11 laptop. I had firefox many years ago and uninstalled it. I am reinstalling and I get a pop up that states: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window:"

I have uninstalled and went through my laptop to remove all references from firefox. Task manager shows no sign of mozilla or firefox running processes.

A check of the crash log is empty.

After being hacked, I removed my Firefox browser and tried to reinstall. However, what I got no longer uses Firefox but instead I can only browse using Google, which I don’t want.

Please help me install the Firefox browser!

Thanks

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.

How do I reinstall Firefox FROM SCRATCH when older settings (but not the .exe itself) is still on a Windows PC? Will deleting all entries in Windows Registry fix it?

Background is that I switched Sata cables for some hard drives (for an unrelated experiment), of which one contained the Firefox installation on D:. Then I ran Firefox, and somehow it seemed to work and I also was promted to install an update which I did. After some days I switched back Sata cables. Now I cannot uninstall old instances of Firefox that I can see in Win Settings -> Apps. Worse, I cannot install Firefox anywhere AND also make Firefox running without a crash after a few seconds. To remove all info in registry and hard drives might be the way to solve this?

my wife's copy of Firefox picked up a virus. After trying several other things, I saved the profile, uninstalled FF, and installed the latest version. But when I tried starting FF I got an error message: Your Frefox profile cannot be loaded. It may be missing or inaccessible.

I'm trying to install version 52.9.0 of Firefox on windows XP. The file available here does nothing when I run it. Windows doesn't show any dialogues or give errors. Nothing happens. When I check on Taskar, I can see the CPU activity go up, but the installer doesn't appear as a process. This is where I'm downloading the setup file from: [http:// https://archive.mozilla.org/pub/firefox/releases/52.9.0esr/win32/en-US https://archive.mozilla.org/pub/firefox/releases/52.9.0esr/win32/en-US
