I installed Firefox ESR today since the website said I should use it on my older operating system (10.14.6/Mojave).

Unfortunately, it fails to fully launch - the menu bar is grayed out.

I re-installed. No help.

I restarted. No help here either.

I stupidly trashed my older version - the one that actually worked, so now I am searching for an older Firefox that actually WILL work. Any suggestions?

Thanks.

The last version of Firefox for macOS 10.14 is ESR 115.28.

Official download page should suggest it for you.
