I wish these three bugs were debugged. Rated 3 out of 5 stars

1. When I set the minimum font size to a bigger font, I can't see the toggled on counter fully.

Edit -> Preferences -> Content -> under Font Color & Size, Advanced... -> set Minimum Font Size to 16

2. When I visit about:addons, I see a weird looking icon in the address bar.

3. When I toggle on the counter, a big empty right-margin appears.
