Breaks my ability to login to and pay via PayPal from Ebay...i finally tracked the issue to TamperMonkey via disabling all addons, then enabling them one by one...bam...TamperMonkey...

Doesnt help that what you think is the disable button in the toolbar icon when pressed, does nothing ...you have to go all the way into Tools->Addons to turn the bloody thing off

Ill go back to Greasemonkey or another alternative for now...

Edit (after dev's reply): Appreciate the reply, and i may revist in future! In the meantime i installed ViolentMonkey, with the same scripts i had in TM, and had no issues - VM was left enabled, and i was able to get through Ebay with no issues. Whatever was mangling ebay/paypal was doing so internally in TM, and not via any of the 3 scripts i had installed, which are site centric and not global. Side note, VM was a LOT faster than TM. Added a star for a speedy reply from dev. I hope you managed to fix it, its GUI is by far the best of all script managers, if you get the backend sorted ill be back.

It can't work on mobile Firefox . (It doesn't have options menu and haven't install pattern on greasyfork websites.

No funciona.

Twitter videos not working for just having this installed.
It's impossible to see the icon on a dark theme.

i like TM, but TM does not support many script from userstyles.org

1. please optimize RAM usage. eating more than greasemonkey.
2. very slow when editing js-scripts
