This is typically something to report on the bug tracker, not valid review content as per AMO rules, so thanks for not weaponizing stars. But it's impossible to have a discussion here, so if you want follow-up, you'll need to go to gitlab.
A few other people have reported the same problem, but I can't reproduce it (and I use my addons myself, so...), but they all seem to do special things like running extremely old versions of firefox or using the tor browser. I really can't support cases outside the 99%, sorry.
