Shows empty navigator.plugins and navigator.mimeTypes collections to selected websites
I'm not sure why this isn't working. I might have to ask the developer if the "run at document start" option is not currently available.
Thanx for reply, I´m using other scripts like https://adsbypasser.github.io/ and is working properly with Greasemonkey 4 and "run at document start" option
Update for Greasemonkey 4
Please, can you update this script to make it Greasemonkey 4 compatible too?
