Where is Firefox.exe located on WIndows 10?
I'd like to add Firefox to Adobe Dreamweaver for site design viewing. When searching Windows for Firefox.exe I don't see it in Program Files or Program Files (x86). Firefox is installed and used daily. Can someone tell me where it's located in Windows 10?
Chosen solution
Firefox would normally be installed in one of these locations:
- (64-bit Firefox) "C:\Program Files\Mozilla Firefox\"
- (32-bit Firefox) "C:\Program Files (x86)\Mozilla Firefox\"
How did you manage to get Firefox installed in "AppData\Local" and not remembering this ?
Edit: To clarify, the default Firefox installation location is usually one of the following:
C:\Program Files\Mozilla Firefox\
for 32-bit Firefox on 32-bit Windows or 64-bit Firefox on 64-bit WindowsC:\Program Files (x86)\Mozilla Firefox\
for 32-bit Firefox on 64-bit Windows

Right-click the desktop shortcut for Firefox and view the Properties. The Target line will show you where firefox.exe is located.
You should see the installation path on the "Help -> Troubleshooting Information" (about:support) page under "Application Basics -> Application Binary".

That's it. Thank you.

It looks like you installed Firefox in the /AppData/Local/MozillaFirefox/ folder rather than the more customary Program Files.

I'm not sure why it was installed there. I just installed Firefox on another machine with Windows 10. The Mozilla installer doesn't show any options for changing the directory. On that machine Firefox was installed in the usual directory C:\Program Files.
C:\Users\Justin\AppData\Local\Mozilla Firefox was the default directory on this machine when installing. Why would the installer point to C:\Users?

Sorry for posting to an archived thread but I thought this was worth documenting, since it happened to me today when testing out the Firefox Installer.
Firefox installs to C:\Users\<username>\AppData\Local\Mozilla Firefox\ when you run the installer as administrator and cancel the UAC prompt (or if you install Firefox in a non-administrator account).

Expected results: firefox should install to C:\Users\<username>\AppData\Local\Mozilla Firefox\ only for the administrator user, just like it does for normal (ie not administrator) users. it seems that administrators users can only install firefox "system wide" and sometimes I don't want to.

Actual behavior: The installer exits.

Just tested it's still fixed in Win10 x64 - AFAIK this has been fixed since 55. Works as intended: 1 User dismisses the UAC prompt 2 Installer launches and installs to the user's home directory
