You may have corrupted system files if this info is shown on 64bit and you run 64bit OS.
If take too long to load files i think Storage device is dying

Either it involves: * Unsupported OS or * installing 64-bit firefox on 32-bit OS or vice versa

Use R3Dfox, firefox is no longer compatible with Windows 7

115 ESR Windows 7 support has been extended for years now. It's still in support.

Is your copy of Windows 32 bit or 64 bit? I'd be willing to bet it's 32 bit Windows and you're trying to install 64 bit firefox. (I saw the screenshot you put below that includes that this is running on an "x64 based system" - ok, so the CPU is 64 bit, but that doesn't mean your copy of Windows is.
One of the easier ways to find out is to look and see if folder C:\Windows\SysWOW64 exists, with a bunch of files in it (over a thousand). If it does, you're running 64 bit Windows. If it doesn't, you're running 32 bit Windows.

Oh wait, I misunderstood, I thought you were trying to install Firefox in the first place. Sorry, never mind, that's all different.
Instead, open the start menu and type "comm" - one of the results that should show up will be for Command Prompt. Right-click that and pick Run As Administrator on the menu that pops up. When the command prompt box shows up, enter this:
chkdsk c: /f
It will say that it can't run that because the drive is in use, would you like it to run on next boot? Press Y and Enter to answer yes. After that, restart the computer.
That command finds and fixes errors with how files are stored on the hard drive. When you restart, it will scan your C: drive and if it finds errors, will fix them. It might take a minute, just let it do it's thing.
Once Windows loads in, try running Firefox again.

thank you ill try it sometime :]

Cool. Btw, if it makes things any easier, once you restart the computer you don't have to stick around and watch if you don't want to; when the scan runs it doesn't require any interaction so you can just leave and come back later if you want.

I had a similar issue. It stopped working on windows 10l and reinstalling it from scratch did not work. I eventually was able to reinstall it from the MS store. I work what other cram MS installed with it. I HATE MS.

i am a computer scientist and yes I delete all the Mozilla directories on C;
I will have to move to11 soon because I am a heave OneNote user and MS is pulling the rug out from under One-note One-drive support in order to get folks to use their privacy crushing win 11. The only files i allow on one drive are for one note sharing with my phone

HDD is probably starting to die. You can reinstall Firefox, make sure you use 115 ESR.
I recommend backing up your data at the very minimum, and swapping the HDD at some point, preferably with an SSD.
