Doesn't Work in FF 50!!!! Rated 5 out of 5 stars

This was a beautiful addon (hence the 5 stars), but currently it makes FF 50 unusable :(

Specifically, it makes everything in the hamburger menu unclickable, everything in a single column, sprites not rendering correctly, and generally a huge mess, which makes firefox want to be so wide it stretches off the screen.

Please fix soon~ thanks.

How to activate the add-on in the newer FF versions (48, 50, etc.) Rated 5 out of 5 stars

To enable the add-on in any unsupported Firefox version download the XPI file by right clicking on the "Add to Firefox" button and choosing "Save link as..." Open the downloaded file with an Archiving utility. Edit the install.rdf file inside the archive. Change the text of the em:maxVersion XML tag under em:targetApplication to 48.* or 50.* or any other version. Save the file and update the archive. Drag the XPI file into the browser window. Restart and enjoy.

Workaround for Firefox 48+ Rated 5 out of 5 stars

If you want to use it in Firefox 48+
Use this extension:
https://addons.mozilla.org/de/firefox/addon/checkcompatibility/

It deactivates the compatibility check so you can activate the Theme. I just tested it and it works.

Please please make it default in firefox Rated 5 out of 5 stars

Firefox looked crappy without this for too long in gnome3. Now it looks audacious !!!!!

I never knew this addon existed. Please try to promote this to the user during / after installation. Users should somehow know that this exists.

No scroll bar Rated 4 out of 5 stars

It looks nice especially with tweak add-on but scroll bar very often disappears. For example when I use Twitter and many other sites.

Scrollbars missing on Firefox 47 Rated 3 out of 5 stars

Almost perfect! With some web sites the main vertical scrollbar is not always shown though (I'm using it on Linux). For example: http://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeAvailabilityZones.html

Great Theme, nice customizability, please in dark Rated 5 out of 5 stars

This theme fits really well with the gnome shell.
I would just wish to have a dark version to match the gnome global-dark theme.
I hope options like these will be implemented via Gnome Theme Tweaker oder just as a second theme from the same developers.
