No problem, I hope it works out for you! Feel free to spread the word to others as well as provide sites that are causing issues for you so I can add fixes to the list.
Just want to say; I'm checking in after a few days of using it and... if i think about it, i guess i'm clicking that "killsticky" bookmark less and less.
its funny, suddenly i don't even have to think about it, which is what this is all about - reducing cognitive load.
re inclusion on ublock and the like: it should probably be an option that people can enable/disable; ublock is more about blocking ads/trackers, but i would wager that most people are annoyed with sticky stuff too.
ready for the next challenge?.... getting rid of sites that fuck with the default scroll behaviour ;)
Ironically, though, this will probably limit severely the quantity and quality of data I can feed back to this Mozilla project via this add-on...
