Re: No Classic Theme Restorer?
The new theme is at least better than Australis (burn rounded tabs, burn), and a few features are still possible through css, but most aren't.
It's SSLeuth that I'm going to miss. The developer has suggested that some functionality might be possible if an EFF proposal is implemented, but Mozilla has rejected every other proposal to expose TLS info. Firefox was the only browser in the world to allow you to see how strong a website's certificate was, now they want to be just as naff as everyone else.
