Thanks.

Great to see this being ported to WebExtensions. Maybe I just can't find it, but there is one thing I miss from the original extension: option to turn on auto-fit zoom *globally*, i.e. everything is zoomed to fit the width of the browser window (including new pages/tabs). This is extremely useful for using external monitors. But in any case, thanks for this addon!

For Per-Site zoom mode, 'browser.zoom.siteSpecific' must besetto 'true' in 'aboufcconfig' preferences

best add on to managae zoom and is a web extension!!

Much better for those just wanting text zoom functionality. Thanks for the hard work.

Other commentators already mentioned it's the best you can find.
Idi0t proof & just work.

The best since the old NoSquint. Web Extensions ready too.

This is the best text zooming addon you can find. It does the job easily without messing up functionality like zooming an image with a scroll wheel. It has per site text zoom and default text zoom. The only thing was that it required me to go into about:config to enable per site zooming.

Don't work on Firefox for Android 48.0, although for android.
