I have been using Firefox Portable for years, but I haven't had this happen before, and I couldn't find any solutions. I usually download each and every update using the normal Firefox update process. I did the same thing this time, closed the browser, and tried to open it again using the FirefoxPortable.exe, but I am getting this error:
Mozilla Firefox, Portable Edition, cannot be started. You may wish to reinstall to fix this issue. ERROR: firefox.exe could not be found
I do see the file exists in \FirefoxPortable\App\Firefox64\, and it does not appear to have any weird permissions or anything (I am running Windows 10).
My question is: where is it trying to find firefox.exe? Other than re-installing, is there anything else I can try to resolve the issue?
