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?

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?

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.

Hi, I have been experiencing issues lately with Firefox. Attempting to install it often comes up with errors suggesting file corruption but I eventually got it to install. However, now it crashes as soon as I open it and in the past before a system reboot on my PC, Firefox tabs crashed very often. I'm trying to diagnose the issue. I have completely uninstalled and reinstalled Firefox multiple times.

As my laptop is currently experiencing other issues, if there's a specific driver that is causing trouble, it'd be great to figure out what's wrong and what is causing Firefox to not function.

My specs are: Asus Rog Strix G614JIR - (GPU: 4070RTX, CPU: IntelCore i9, SSD 1TB, 32GB RAM).

I have attached the most recent crash. Any help is much appreciated. Thanks.

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 have been a long time user of FF and have been puzzled by it's recent failure (to both start, and subsequently re-install) For the last 18 months I have been running Win 12 without problems. That is until last week, when I can only assume the Tuesday udates ( MS) has created havoc. I would appreciate any assistance as I am not fond of MS Edge, or Google Chrome. Dave Hickman.

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/.

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.

I am trying to install firefox on my new work laptop. The OS is Windows 11 Pro. It came with an ARM CPU. Specifically: Snapdragon(R) X Elite - X1E80100 - Qualcomm(R) Oryon(TM) CPU. Everytime I try and install Firefox, which is probably over 10 tries by now, it fails with generic errors. I have tried cleaning everything Firefox related off the PC before subsequent attempts and still get the same errors. I am including a screenshot of what I see shortly after starting the install process.

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.

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.

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
