What are you using on your Chromebook?
For years I used AdBlocker Plus.
Until they stopped working in Boardhost.

I switched to uBlock and it has been wonderful everywhere on the internet.
Now they are saying it may go out of business because it isn't updating on Chrome.

So I just tried downloading three others from the Web Store to check out. And they won't install.
They just sit there spinning trying to install.

I haven't removed my uBlock, until I can try something else. I had it turned off while I was trying to download those others.
Not long ago I tested Ghostly Adblocker and it didn't work well for me.
