Pre-quantum, this was one of my favourite extensions. Bringing in something Mozilla themselves forgot. Now, though, with the requirement to install a separate app from a random developer, just seems fishy. I certainly can't use it at work anymore. A real shame. I'm blaming Mozilla for this one, the whole extensions change is basically just "here's Chrome but with the name Firefox", which is crap. Sorry for the negative review, I just can't use this anymore, and I'm a little mythed, as I did like this extension.
