keyboard shortcut doesn't work in zooming in
basically, the keyboard shortcut or navigation enhancement for zooming in on a page or window stopped working, not long ago . . .
when i press ctrl plus the + key on the digital keypad at the right end of the keyboard, the text stopped becoming larger . . . and the browser doesn't zoom in . . .
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
You can also try "Reset all user preferences to Firefox defaults" on the Diagnose Firefox issues using Troubleshoot Mode start window.
The DEFAULT theme was already selected (Tools > Add-ons > Themes)
Trying to locate the "Safe mode start window," I was unable to see or notice the "Safe mode start window."
If I were able to see it, I would try the above "reset all user preferences to Firefox defaults" suggestion.
Does anyone know how I could find the "Safe mode start window"? I assume it displays after the Advanced Options menu appears.
