with so many better licensed options closer to fupl/agpl3 (the only good license), i still see zero reasons to try this (immediate zero stars, as failing with this most basic reason to even write software only do harm, in my opinion, and create useless jobs) even if it tries to fill the "hole of what other similar extensions do not do (if one of them had the right license and according mindset, all devs would work together to make 1 simple and good solution for users, rather than create a new babylon).

{i also understand this review might feel on the border of the guidelines, and not so easy to read, but i do what i can and i feel mozilla might understand the importance of promoting free software and paying attention to the license}

very interesting it has such a huge support from mozilla. perhaps it helped to pioneer this whole branch of allowing scripts on browsers, even if greasemonkey actually came first? still i keep it with 1 star because can't give it zero, and because i would give it 1 anyway if it really did help to bring this important job (browser scripting) to life. ~acauema

The latest update makes every page, regardless of whether I have scripts enabled for them or not, completely unable to load

It freezes Firefox when using YouTube.

an update just completely deleted about 15 years' worth of scripts i have been collecting and configuring. im Very impressed and full of praise for the developer.

Horrible addon. It randomly deleted all the userscripts I had installed. Use any other userscript manager but this

Sorry but this is not free and open source, it was a sad surprise for me.
