From March 17th, 2018 to July 2nd, 2022, 50% user give 5-star rating, 50% user give 1-star rating. for Clipboard Permission Manager chrome extension.
It just doesn't work. The extension button shows up as a "?" icon (as opposed to what the screenshot shows, which is a green checkmark indicating that clipboard acces is allowed, and I presume some red sign of some sort when not), and the menu doesn't contain any option to allow/disallow clipboard access for the current website, nor are there any options anywhere to allow it globally or on a per-site basis. It just does nothing, it's obviously broken (but it doesn't show any error allowing you to diagnose the issue either). Basically garbage, I wasted my time trying it out.
I just now downloaded it and it seems to work just fine!
I works for Apache Guacamole
After installing in Chrome 65.0.3325.162, provided no option to allow website access to local clipboard. Tried after relaunch as well.
