I had Firefox but it's gone and I can't get it back; says something is missing.
One day I opened Firefox and it took me to Yahoo.ca. I tried an upgrade and a popup box asked me to choose between deleting one file or another. I guess I chose wrong because now, even though I uninstalled the browser, I cannot reinstall Firefox at all.
The pop-up says: Your Firefox cannot me loaded. It may be missing or inaccessible.

You can download the Firefox installer (currently 44) on a USB flash drive, then plug it into the computer and install it.

You need to locate the profiles.ini file and delete this file or use the Profile Manager to create a new profile.
See:
This issue can be caused by a problem with the profiles.ini file or with the permissions (owner) of involved folders.
You can use one of these to make Firefox create a new default profile or recover an existing profile:
- Delete the profiles.ini file to make Firefox create a new (default) profile
- Use the Profile Manager to create a new profile
If you still have an existing profile then click "Choose Folder" in the Profile Manager and browse to the location of a lost profile to recover this profile

You should find the profiles.ini file in this hidden location:
- Windows: %AppData%\Mozilla\Firefox\
*C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\ - Mac: *~/Library/Application Support/Firefox/
- Linux: *~/.mozilla/firefox/
If clearing the profiles.ini file isn't working then also check the location of the cache files.
- Windows: *C:\Users\<user>\AppData\Local\Mozilla\Firefox\Profiles\<profile>\
- Mac: *~/Library/Caches/Firefox/Profiles/
- Linux:*~/.cache/mozilla/firefox/
You can also try to rename/delete the Mozilla\Firefox\ folder in both above mentioned locations (main, cache).
