Рейтинг 3 из 5 звёзд

I use this instead: "User Agent RG". Seems to do what this add-on does but with more options.

Works, but could be a lot better due to:
1. Needs to remember it's previous state between startups.
2. The UI button doesn't get treated the same as other addon buttons. I.e. It doesn't get that 'raised' effect like e.g. ABP or NoScript will.
