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.

Hi, just tried to access Firefox via an existing PC desktop short cut and it said "The item "firefox.exe that this shortcut refers to has been changed or moved, so this shortcut will no longer work properly. Do you want to delete this shortcut?" Not sure why it's suddenly done this.Should I delete the app via "Add remove" and re-install.

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)

This article：https://support.mozilla.org/kb/install-firefox-linux. I want to install Firefox offline or use the deb package directly. My system is arm64.

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

I have a Windows 7 PC. IE no longer works. I would like to use Firefox to access the Internet. Firefox offers a version for download. I got it using my Windows 11 PC, however it fails saying that it can only be installed on Windows 10. Can this be fixed? I cannot access the Internet from my Windows 7 PC.

It appears my Firefox system is operating under Windows 10, which creates an issue with my email because, currently I'm running the Windows 11 operating system!!!?

  Is there a solution to this Problem?

I've used Firefox for year but this morning it would not open. so after trying everything else I uninstalled it and tried to re install but the new installation will not open

Due to a technical issue, I've deleted Firefox and re-downloaded it. However, the SHA hash doesn't match. shasum -a 256 [path]/Firefox 134.0.2.dmg shows a hash of:

c87eade89ddf5d1996766840809b5d415d91ecb696326b4f1f92210200978d21

but that hash doesn't show anywhere on https://releases.mozilla.org/pub/firefox/releases/134.0.2/SHA256SUMS

mac/en-US/Firefox 134.0.2.dmg shows a SHA sum of:

7832a8d1e1a13322dec1b52d32e1e64d2b6254de8348575f2d22af4975d56a85

which is completely different.

I re-downloaded it, this time from https://www.mozilla.org/en-US/firefox/all/desktop-release/osx/en-US/, and this time the SHA sum is:

47e1c3b84e79d331842ccf994be56cd423126eaca6acfd1664d668cf48f98de0

which is yet different, and is also not found on https://releases.mozilla.org/pub/firefox/releases/134.0.2/SHA256SUMS

What's going on? Why can't I get a matching SHA sum?

I want to download and install Firefox on my new iMac. As administrator it downloads but the instellation won't run. As a user it downloads and I can move the icon into the application folder. Firefox then opens but it won't run. Everything is frozen. What is going on??

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.

Hello, everyone,

I don't seem able to install Firefox on a Windows tablet (at least I think it's a tablet, it's an Asus Transformer Book, with a tablet screen and a detachable keyboard, anyway). Does anyone have any ideas why, please?

I should warn anyone before they read on that I am in no way techie, so helping me may be frustrating at times as I need advice/instructions etc spelled out really simply, as anything too technical is beyond me, I'm afraid.

So, anyone brave and/or patient enough to read on... I've bought the tablet secondhand, 'wiped' etc. It's an Asus T100HAN Processor: Intel(R) Atom(TM) x5-Z8500 CPU@ 1.44GHz 1.44GHz Installed memory: 2.00GB System type: 64-bit Operating System, 64-based processor Pen and touch: Full Windows Touch Support with 10 Touch Points

It's currently running Windows 10 Home, but I'm hoping to install Linux Mint on it, although it's only since I bought it that it's occurred to me that putting Linux on it might not be as straightforward as I thought, (ie I'm typing this on a laptop that came with Windows but on which I installed Linux Mint. "If Linux runs on this, it must run on anything that can handle Windows," I thought to myself before buying the tablet. But now I've realised that, eg, this laptop doesn't have a touchscreen, not does the screen have to rotate, which is the main reason for buying the tablet.)

That's sort of a digression, but might not be, as it explains why my priority right now is installing Firefox on the machine - so that even if it turns out I can't install Linux on it, at least I'll have Firefox rather than Edge or whatever.

So, in the Edge that came already on the machine, I accessed the official Mozilla page (despite getting several scary warnings from Edge about there being a problem with "this website's" security certificate, oh, and something about "Windows SmartScreen can't be reached at the moment") and downloaded Firefox. I went for the desktop version because that seemed more relevant than the Android or iOS versions. Then I've told it to "Run". The installer thing has come up and the little colour wave thing has happened with the icon in the taskbar (or whatever it's called). And then, after several minutes, I've got a message from Firefox Installer: "Hmm. For some reason, we could not install Firefox. Choose OK to start again." So I've clicked on OK, and the same thing has happened. Several times. And I've downloaded Firefox umpteen times as well, just in case there'd been an issue with that first download, only the same thing has happened, over and over again.

From the "about" thing, it looks like the 30GB or so of storage on the tablet, but about 10GB(!!!) is taken up by "system files to help Windows run properly. Your PC won't work without them."

Can anyone explain, please, what's going on, and what (if anything) I can do to get the wretched thing to allow me to install Firefox? I could just about cope if I can't get Linux, but no Firefox??? No, no no!

Thanks, Alice.
