Firefox won't open at all on MacOS Mojave V. 10.14.6
It bounces in the Dock once, looks like it tries to open, and then quits. I've uninstalled it thoroughly including all the system files then re-installed, won't help. Restrated the Mac still no good. Please help.
Odd. Perchance, are you using the Facebook plug in? I ran a quick Google search and found this post https://support.mozilla.org/en-US/questions/1240674. Hope this helps.
I've come across thru this post before. After running searches I couldn't locate any fbplugin anywhere :/ I am clueless why this is happening...
