Same.

It doesn't work at all. "Discard all inactive tabs" has no effect either.

I reinstalled the addon and it still doesn't work. Are you sure you are using FF 60.0b7 or newer? It worked fine before this version.

What do you mean paired to another addon? Nothing has changed. FF Developer Edition got upgraded to 60.0b7 and this addon stopped working. Nothing else changed in my setup.

I figured out the problem. By default "Do not discard a tab if it can display desktop notifications" is checked. This didn't give me any issue until about a week...

Also, I'm using FF Dev edition, which should have newer builds than standard FF. Something might have changed that causes this feature to not work properly anymore. 

It will become an issue for everyone once FF catches up to this version, so the developer should be made aware.
