Breaks half of all webpages and causes tons of lag

makes youtube video completely dark, same with other video pages, unable to select to only apply to specific pages

A great addon in theory but in practice it makes pages load 4-5x slower than normal firefox, or not load at all meaning you need to keep refreshing until the page works again. This extension would be a 5 if it didn't have any performance impact, however in its current state I would not recommend it.

This thing made my lapup sounds like AC outdoor unit when trying to adjust brightness

WTF? Didn't work

I removed hours after installing as it made my CPU utilisation jump from 7% to 97% all by itself. It has good features, but it is not worth it if my PC sounds like it is about to explode from it.

Suddenly installed when mozilla does its clusterfuck install when reinstalling mozilla. Dunno why it was installed, but it can fuck right off.

New update unfortunately breaks cookie popups leaving me unable to interact with any website that gives one. Half the time the cookie popup doesn't display properly, and the other half I can't click on anything on the page (including to accept/deny cookies). I've sadly uninstalled it for now.

As other users have mentioned, it's making firefox unusable. I've had to restart it numerous times because of this extension. Loved it when it worked.

Absolutely trashing performance on firefox. I think this is in theory a great add-on, and it has been in the past, but it is unusable in it's current state

Spammiest piece of garbage. Like 6 slide in attention grab popups. Almost threw my phone in the river.

Peddles Malware.

look good on some site and not so much on others but the deal breaker is it slows down fire fox sometimes so bad firefox tell me it turn it off yikes

reenabled itself without asking. absolutely unacceptable. uninstalled

It literally broke the first website I tried it on.

Functionary not

It's been at least a month since the extension ceased to be functional. If they can ever return it to when it functioned, I'd be happy to re-install, but it's worthless for now.

This extension used to work flawlessly... years ago. Now, it's a broken piece of junk that routinely breaks pages, causes major performance issues with FF and tabs to crash, and makes text/images so dark as to be unreadable. I'd rather suffer through the blinding light, thanks.
