Firefox quits unexpectedly--happens frequenly
Firefox crashes repeatedly. This has been happening for over a year. Usually beforehand the following message pops up: Error while installing Expecting value: line 1 column 1 (char 0) (I usually choose ok when this pops up so the pop up will go away) Then I have to restore the session. I have an older MacBook Pro (mid 2009) I prefer Firefox to Chrome, but this is so annoying, and I'm always worried that my whole computer will crash at some point...

Is that the whole error message? What is being installed?
Let’s do a full clean re-install;
Note: Firefox comes in three or more folders on all computers. They are;
Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And two folders in the profile of each user on the computer for each Firefox profile for that user.
If you remove the Firefox folder, the user profiles would not be affected.

Note that Firefox 78.15.0 is the last version for your Mac OS X platform (update channel: mozilla-mac-eol-esr1), so you will no longer receive updates.
You can create a new profile as a quick test to see if your current profile is causing the problem.
See "Creating a profile":
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
