Firefox Permissions

[buster2209]

When I run firefox as a superuser (sudo su), it works fine

When I run it as a normal user, the bookmarks and the back button wont work

I assume this is just a permissions problem with the firefox folder where it is installed

Can anyone tell me where it would be and what command I have to run?

somewhere here I've noticed solution for that:

sudo chown -R usname:usname ~/.mozilla

(disclaimer:I havent' tried it ... )
