Preference named layout.css.devPixelsPerPx
I wanted to make the standard zoom in Firefox a little smaller, so I went to the preference named layout.css.devPixelsPerPx in about:config and messed around with it a bit. I wanted to change it from -1.0 to 1.2, but I accidentally typed 12 or 102 instead of 1.2, and now the Firefox screen is so huge, I can't do ANYTHING on it, so I can't change the preference back to 1.0 or 1.2 or whatever.
Is there any way to fix this without having to completely uninstall firefox? I'm loath to lose my settings and favourites...

hello Japser, you can perform the following steps to change the value again "blindly":
- open firefox and press ctrl +L (this will put the focus into the location bar)
- type about:config
- press enter twice
- type devpix
- press the tab key
- press enter
- type 1.0
- press enter again & hopefully you should be back to normal visibility now
