Thanks for the positive review. I have tested and indeed confirmed that the UI is broken on Firefox when loading with tampermonkey (may be broken in other setups but violentmonkey seems to work correctly). Will fix as soon as possible. Another reply will be added when the update is out.
The bug has been fixed. Apparently TamperMonkey dos not fully support GreaseMonkey 4 so the script had to be changed to call GM3 functions instead.
Has some minor UI issues, but the main function works great!
