I inadvertently installed 142.0 for Mojave 10.14.6- by mistake and now it starts up in the version 142.0 (which is not for Mojave 10.14.6) when I click on a link - I get an error and a log. I just open the correct version 115.26 everything works fine and I just have to copy and paste the url. I trashed everything my Library - Firefox folder and Mozilla folder- emptied the cache, history and cookies. Reinstalled Firefox from the Mozilla site, but to no avail. Hitting a link starts up in V. 142 and Firefox quits and throws an error log. What do I need to trash so this does not happen. Thanks
