misterrobot says:This is fraud extension which adds CoinHive miner script to every page you visit! Who knows what it could else do. Be careful, don't install it.

I love this extension, however there seems to be a new bug.
It locked my computer up by opening around 1000 tabs. ( X299 system, 16 threads at 4.5GHz with 32GB memory at 3GHz and dual 1080s on SLI )...
It wouldn't stop opening tabs either, it got caught in a loop and kept on opening the tabs...
I had to close opera.exe from task manager ( so it didn't 'lock' the pc up completely, but 2 windows went black which clued me in to something going wrong and I noticed Opera opening a ton of tabs... ).
There were so many tabs being opened, I could no longer differentiate between individual tabs.
Then, as quickly as the issue started, when I relaunched opera, Tampermonkey closed all of the tabs, automatically.. without closing my tabs which is good.
Still, getting caught in a loop and opening hundreds / thousands of tabs is a problem.

Please note: The person who said that CoinHive miner script is added to every page because of this extension is lying.
I have used this for years and I am a computer scientist. I also monitor all of my traffic.
Something you can use is UMatrix - it'll tell you what sites the site is trying to access - none are CoinHive, and each website is opening a lot of crap for that particular website - nothing is the same across websites other that my framework running through this addon...
It is possible the user installed a script which added coinhive, but that isn't TamperMonkeys fault. It is your fault for installing a bad script into the extension - there is a warning before installing... Giving a bad review over something you did wrong is bad.
