It's handy sometimes, but lately it's been far more annoying than helpful. It does this thing to prevent clipboard hijacking where it gives a popup whenever I copy something, and then prepends "[SUSPICIOUS CONTENT]" to the start of the clipboard, and I do a lot of copy-pasting; so the only thing hijacking my clipboard is this extension.
I removed its clipboard permission to stop this, and now once or twice a day it will hijack my browsing session (usually in the middle of watching a video) to open a new tab and ask for permission back.
