Great but with a minor bug Rated 4 out of 5 stars

This add-on is really great, makes you wonder why it's not in Firefox by default.

It works wonderfully with the exception of one problem, doesn't seem to work when on a private browsing window.

Really useful! What about Thunderbird? Rated 5 out of 5 stars

Been using it since discovering this add-on and now I'm missing its practicality in Thunderbird when viewing messages.

Any chance to also provide it for Thunderbird?

Thank you!
