Re: Can I keep firefox at a 125% zoom level? I use my HDTV as a monitor and would like the view to be larger without having to hit "ctrl +" on each web page.
The following Add-on will allow you to set whatever default %-age works best for you. After install, go to Add-ons > Extensions > Default FullZoom Level > Options, in the Options window, "Default FullZoom Level (percent)". That will set ALL pages at your choice.
