Today, Firefox showed me that a refresh can speed it up. So it took me to this website https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings?redirectlocale=en-US&redirectslug=reset-firefox-easily-fix-most-problems#, but the
refresh button is not working at all. Then the option 2 said that
about:support also has a
refresh button, but there was nothing like that in that page.
Second, I want to change my account pic for Mozilla account, but https://support.mozilla.org/en-US/users/edit has no option to change it. The bluish dummy avatar above
Display name is not clickable too.
Using Firefox(LTS) on Debian 10.
