After some months of non-use I can’t start up the program
Running MacOS 15.5. Former Firefox user, have not used Firefox for many months. Recently (last few months) when trying to startup Firefox it has not run successfully; always fails with an error message something like “Unable to load user profile …” and then Firefox immediately exits. Today downloaded newest Firefox v139.0. Now the same thing happens; but the failure message comes in Icelandic and Firefox exits immediately. How can I get past this ?
