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.

For the last few days, Firefox is being removed from my computer overnight and i have to re-intall the browser the next morning. Sometimes it's still there the next day, and sometimes it's gone again the next day. What i causing this and how can i prevent it from being removed? Jenny

I need/want to download Firefox Browser for Android. When I push the install, a pop-up says I have to sign in first! When I touch it, it goes back to Google Play! Is this requirement from Firefox? Google scares the AICH out of me!

I seem to be unable to install Firefox on my Windows 11 desktop because there is apparently an old version already on my computer. I wish to reinstall Firefox with your help

Present version of Firefox does not support my computer. Please help... I want to access Chase Bank R. Schnepf [edited email from public community support forum]
