PROTIP: To stop the G! login popup window from annoying the piss out of you when using Firefox, simply add what’s below to your uBlock filters:

||accounts.google.com/gsi/iframe

Worked great for me.

Full instructions:

1. Click the Ublock Origin icon (a shield like thing with a number in it in the upper right of desktop Firefox)
2. Click the gears to go to settings (almost at the bottom and on the right of the drop down)
3. Click the My Filters tab and paste what’s above into the next open row (for me this was my first filter).
4. Stop seeing the silly box to log into sites using G!.
