  • (2021-09-21, v:1.2.0) UnluckyNinja: How about a toggle button
    I use it to develop userscript for other sites. Mainly to insert localhost to "script-src" etc. But for security purpose, when I'm done developing, I have to disable this ext or comment out all I added in browser ext settings. It will be very convenient to have a button toggling it by one click.
