It works great, but too heavy on my browser :(

Good

Much faster than other dark mode extensions, however it has a tendency to break icons and images.

loading fast than Dark Reader and work fine, good job
but sometime load "discard tabs" will break the web page

edit: After 2 year ago now I change rating to 4 star,
because even now it still easy to break the web,
When FF startup load "discard tabs" will not effect dark mode,
and whitelist sometimes not working(ex : reddit in wihtelist but this addon still blocking img)

Worked!

worked!!!

Truely fastest dark mode!. But I give 4 stars because dark mode is sometime not applied in case: back to previous page, some websites

Thank you for your work. Very promising, and an interesting underlying idea. Looking forward to see continued development!

Really nice and pratical add-on ! Even more so since last update patching reported website breakings.
My eyes can now keep gazing at the abyss.

if it handles accented letters and vharacters it'll get thwe 5 star! well done mate. Would be the best if those are okay. :) keep up!

THANK YOU! For creating this. I know that Dark Mode is purely aesthetic for some people, however because I am light sensitive. This is a freekin life-saver. Don't even care that I might have to whitelist some pages to keep them from breaking... This is worth it.

UltimaDark has the potential to be the best dark-theme add-on (ever). I'm using the word "potential" just because now UltimaDark is in "experimental stage". But the Dev is very active and responsive, and he is working very hard to improve the add-on, and to add new features. Progress can be followed at Dev' GitHub.

Yesterday the ON/OFF was included (among other improvements). And white-listing is already on the way. Other features are planned, and surely with time we're going to see great new stuff.

Most of the webpages work great with this add-on. And only few webpages have issues (but currently the Dev is working on it, trying to fix everything). It's worth mentioning that is impossible to build the perfect dark-theme add-on. Lot of webpages are badly programmed, and it's not easy to deal with them. Every dark-theme add-on has imperfections.

IMHO UltimaDark is great firstly because its browser performance (webpages have a good loading speed). And secondly, this add-on has very nice aesthetic results. In brief, this add-on is great for the relation: "Browser Performance" VS "Aesthetic results".

Thank you and congratulations to the Dev!
