Awesome, it's better than most dark mode extensions.

Breaks Spotify and changes my Google Sheets font color to white for some reason while keeping the background white.
Otherwise works pretty well

Had this dark background for years. It the only one I use that's easy and does what its supposed to. I especially like that it highlights text. I like to go through videos from channels I like on YouTube. With this extension if I have seen this video it highlights the video title so I know I have seen this video. It does it in other areas also but that helps alot and helps me keep my place in different sites and areas. The only problem is that ESPN.com doesn't work well with this extension. It screws the page up unless I do some maneuvering and even then it doesn't always work. If it could work well with ESPN it would be perfect but I have to disable it on there. Great extension though. If the ESPN situation changes then I can give it 5 stars. It looks good and works almost as good.

Very easy to use addon with some minor customization. I'd like to be able to whitelist/blacklist websites to auto-apply (or not) the filter to, instead of having to do it by visiting each site in turn (it also more often than not breaks the website's formatting if you enable/disable the addon, forcing you to refresh the page).
There's also some flickering between the light/dark themes I've noticed in Google Sheets specifically when you enter a tab, but it only happens a couple times. Does exactly what I need in there (darkening the background but leaving the document whatever color it should be) and works well so 4/5. Just a few bugs to iron out and some more QoL features for the options page.
EDIT: I've noticed that it lags some sites, especially noticeable when scrolling. Disabling the dark mode entirely resolves it. I may end up removing this addon as it's proving more annoying than helpful.

Liking it! Does what it says. Looking forward to seeing upgrades that help with sites that display multiple text styles. Interestingly, social media sites - specifically, TikTok and the site formerly known as Twitter (to which Musk only has a lease on - not ownership of - its current domain name) get even more radicalized when using DBaLT. Frankly, that's not a bad thing. While Tiktok can be useful for getting messages out, anything that dissuades users from hanging around either site is a good thing for our species!

Great addon, though for some reason it gets disabled every once in a while on some pages where I have configured a specific theme

Faster but less flash than DarkReader. If you have a really old, low-end machine like I do, use this instead.
