A "must have" Rated 5 out of 5 stars

This is always one of the first addons I install when I have to set up a fresh profile. Even though I don't ordinarily need it, it is worth having installed for those times I do need it. Awhile back, I was setting up a webapp, and it had a greyed out checkbox, forcing me to do something I did not want to do. RightToClick allowed me to uncheck that box.

This review is for a previous version of the add-on (2.9.4.1-signed).
