NoSquint is a Firefox add-on that allows you to adjust the text-only and full-page zoom levels as well as color settings both globally (for all sites) and per site.
Just installed Firefox 42 on Windows 10 Home. It has your add-on along with Forecast Fox .. for some reason, the Zoom Magnifier is now part of the Forecast Fox toolbar and I can not seperate it. It was working fine in Firefox 39, not sure which Firefox broke it or if the issue is with No Squint or Forecast Fox or the lack of normal Classic Themes in Windows 10 .. Please see if this can be resolved.
