Like someone else mentioned, I looked at some other similar extensions with weird permissions and some of them deobfuscate their code so it is very hard to check it and see what it actually does. I like that this code is really clean and easy to understand, even for someone who isn't an expert. Thanks!

Just what I need. Other similar extensions declare many suspicious permissions (such as access or access to all tabs, or even just the current tab) which to me just seems very suspicious and puts me off.
