Windows cannot find C:\Program Files\Mozilla Firefox\firefox.exe I have tried all of the solutions I can find on this forum (downloading all of the free antimalware kits and scanning for malware and allowing my firewall to make an exception for FF) but these have not worked. Strangely I also cannot open any MS Office files either. Use Avast.

when i tried to open firefox today, it said that it could not find c:/program files/mozilla firefox/firefox.exe. when i go to the file location it is there, but is listed as a .sig file? is that right? i have tried registry editor, uninstalling and reinstalling, etc. i have not done windows update 1909 because i did it before and things went all wonky so i went back to 1809. i don't know if that could have anything to do with it? is there a difference between just downloading firefox and i keep seeing "full version"...i am very confused. and fairly tech savvy. help, please. thank you.

Windows Cannot Find Firefox.exe

Hi,

I've been using firefox for a while on this computer now, but this morning I was hit with a popup saying: "Windows cannot find 'C:\Program Files\Mozilla Firefox\firefox.exe'. Make sure you typed the name correctly, and then try again."

I have so far tried every fix I can find (which aren't many for this glitch), and none have worked. I have tried uninstalling and deleting all folders related to Firefox, and the new install still gives me the same error. My OS is Windows 10, and I have not had any problems with Firefox before this morning, nor have I made any changes to the files or anything of the sort. Just tried to run it and it gave me this.

I am at my wits end a bit with this. Help!

Ever since a random point in the middle of the afternoon today, Windows 10 has become completely incapable of running firefox.exe. I have done a complete reinstall multiple times, wiping any and all traces of Mozilla from my system before running the installer again. I have run antivirus scans, and attempted to start Firefox with my antivirus (Avast!) completely disabled. I even tried starting firefox.exe from the command line, using tab completion to ensure that the file existed. No matter what I do, I get an error message from Windows claiming that it can't find firefox.exe, even when this is the result of double-clicking that exact file. This does not happen for any other software, including the portable version of Firefox (which is useless, since nothing is saved and I need my addons). I'm beginning to think that this is the result of either an absurd mistake or deliberate action from Microsoft, as there has been more than one Windows update within the day, and I have noticed other weird issues like my desktop background occasionally just being removed from existence for no reason.

This morning, when I tried to open Firefox I got a message saying that Windows couldn't locate the file.

I originally just clicked on the icon on my screen.

I then tried going to the program file folder and opening by clicking on the exe file. Same message.

I tried downloading a new copy of Firefox.

The same message came up when I tried to open it.

I made Firefox an exception on my security software. No change.

Any ideas what to do next?
