As much as I love this extension, it occasionally loses it's functionality. Now this usually occurs after a Ff version update. To the developers credit, he updates quickly. However, yesterday was an example of how it sometimes fails for no apparent reason. Ff v 50.0.1 wasn't even released to the software sites like MajorGeeks and I still had the version of T F & S C that had been working flawlessly. I first checked to see if there was a Ff update. Then I tried updating the extension, which indeed was up to date. The most bewildering thing, and it has happened before, image restoration does not fix the issue. It's like the Ff profile is in another world. So, can I set my current toolbar font sizes and remove the extension? Thank you!
