Thanks to Reviewer OldTabby Rated 5 out of 5 stars
I got my favorite theme, Red Cats - Green Flavor, to work with my updated Firefox browser. I had delayed upgrading from 13.x, but once I saw OldTabby's excellent instructions for changing the maxVersion, I upgraded. I have WinXP, and I was able to use the "Install Add-on from file" function with no problem using the jar file. I restarted FF, and I had my red cats back. I love this theme and have used it for years on all of my computers, and Firefox just wouldn't be Firefox without it!This review is for a previous version of the add-on (5.5.2). This user has a previous review of this add-on.
