Import not working (both import and copy/paste)

[suga...@gmail.com]

See attached screenshot. I have tried importing multiple times using both file import and copy paste methods. It just gets stuck and no progress is made, even after waiting for 15 minutes (I made a new facebook edit today and it only takes about 10 seconds to load that)

This was my favorite look for facebook for a long time and for some reason all of my add-ons disappeared today after starting in safe mode and then starting in normal mode after closing everything. I know add-ons are disabled in safe mode but it looks like it also completely removed them from firefox even when not starting in safe mode now. 

this is the contents of the text file I'm loading:

Style 'purpleandteal' for facebook.com

The following part is for use by the Firefox Add-on 'Color That Site!'

Thanks for any advice you can give. I've enjoyed this add-on for a long time, it's unfortunate it was removed somehow today for me and I lost all my edits after reinstalling.
