老眼で字が2重に見えたりしていたけどこれにしてから、ちゃんと見えるようになった。
サイトもキレイだし気に入りました。

I do not understand how this can be a recommended add-on. Yes, it does the job and it looks pretty and all that. But I have never had an add-on that made my pages freeze up and cause my browser to crash before this. It's almost impressive to see how they managed to mess up such a simple thing. Refreshing pages take forever and when I resize my windows all of my tabs lock up, stuck between the original width, to the new width and everything in-between. How do you manage to make something that is supposed to only change the appearance but somehow invents more problems??

Works ok but not with scanning QR-code. Therefor you got only 3 stars. I got the QR-code in the color GREEN. My bank-app did not recognize the QR-code. Maybe an option to change your code when there is an QR-code to be scanned.

it works perfect and I recommend it a lot if you like the dark themes

I like the addon very much, but the webpages are slowed down by a factor 2 or 3! So no thanks.. It's just too slow.

The functionality is great, but unfortunately it seems to slows down my browser, freeze Firefox & prevent it from shutting down properly, forcing me to restart my computer multiple times a day.
