Sorry, there was an error in my post. `~/.mozilla/abrowser/` contains all of
your Abrowser profiles, which are directories of the form
`$RANDOMSTRING.$PROFILENAME`. Each profile has contains its own `prefs.js`
(and optionally `user.js`). In your case, the only profile is
`rwjebu0c.default`, so look for `prefs.js` there.

consider switching to 9.0 repos and running a system update/ upgrade, to see
if that would fix it.
Trisquel 8 and Trisquel 9 have the same version of Abrowser, so upgrading
will not fix this particular issue.
