This is one of the must need Extension on my Firefox but the way it just stops working on few sites in completely unacceptable when it works quite fine on Chrome. LinkedIn, Facebook and even Instagram and Gmail doesn't work properly with this one where it doesn't make elements dark somewhere and sometime takes the entire site down with it just like Gmail.

Tried Dark Reader for a couple of weeks and had to uninstall. Keep getting script errors in conflict with regular Firefox use. Otherwise I like the features and controls. Script errors just became a nuisance.

Works fine so far, better than alternatives.

Is quite good when it works, but far too often Videos or Images are also completely 'blacked out' on websites, for instance on BBC or Amazon sites, thus making those pages/sites virtually unusable - shame

Nice Danke

All I see is "Loading please wait"

Pretty great, this plus f.lux == happy eyes

I recommend users set the behavior to only activate the add-on on the listed websites though.

I have an i7 8700 and 16Gb of ram, and still some of the more complex websites (robertsspacesindustries.com to name one) will bring firefox to a crawl when trying to do the dynamic theme thing to them.
