Rated 4 out of 5 stars

Still a problem with file not found with html help pages even at version 3.0.0. (en-GB locale) Will check in your GitHub for updates. ;)

This review is for a previous version of the add-on (3.0.0).

Thanks for the review!
I already have a beta with this fix. There are a few other patches as well.
