I tried this a few months back, I liked the visual effect and the configuration flexibility, but it ate at my CPU waaay too much. Anybody else have this? Was meaning to look for a lightweight alternative. Maybe I'll try this extension again to see if it's still a resource hog.
Bad performance in Firefox is a known issue and I'm working on improving it. It's not an issue in Chrome and Safari. Low performance can be noticeable in new GMail design, but the reason is their heavy stylesheets full of unused code and images, that Dark Reader tries to analyze. Some day it will be fixed by adding some static themes for popular websites.
I've tried it just a few hours ago, at the moment it's my goto alternative, cheers! The only downside to your extension is that I can't regulate the visual contrast, so some text, like HN content text, is a bit too glaringly bright.
Also, I'm not sure why, but the monospace text in the HN reply box is quite unpleasant to read when inverted.
Just added the extension to give it a whirl. My CPU usage is 3% to 4%, memory is ~37%, on an i7 wih 16 GB RAM (and about 100 tabs open in Firefox).
I like it. I was looking for something like that for a while. Nighttime browsing on LED monitors seriously hurts my eyes, even with night light settings on. This looks like it'll do the job. I'll know tonight :)
Wish you luck. The resource usage spikes I was experiencing were happening sporadically and some sites were more prone to it than others. I've just installed it again, we'll see how it goes.
I just bought for Safari and immediately uninstalled because CPU usage was too heavy and didn't come down. Also, permissions are way too intrusive, why does the extension need to have access to all of my browsing history?
The browser doesn't separate what injected script can do and what it can't. Regarding Dark Reader, it needs to know page URL to determine if it is blacklisted by your settings or not.
Note: I'm on Firefox.
