This extension will slow your browser down like hell...! At one point I almost switched to chrome thinking it was firefox that was the problem. Firefox would take nearly 10 minutes to start after a few days of installation of this extension. And even after the browser has started it would take decades to load the site. And suddenly every thing started working smoothly as soon as I uninstalled this piece of crap. A piece of garbage is what it is..! This should be removed from the add-on store all together if not improved.

An absolute must have. This extension does an incredible job of automatically converting the entire internet to dark mode, greatly reducing eye strain. Its styling rules are almost perfect, in most cases better than the websites' own custom-built dark themes. The keyboard shortcuts work well to quickly toggle Dark Reader for the occasional site that it doesn't play nicely with.

Looks great, but it causes frequent slowdown and hesitation on web pages. I know this extension is the problem because when I disable it, the issues go away. I prefer the "Dark Background and Light Text" extension.

I am giving only 4 stars although this extension is very usefull and user friendly from my experience for 3 years, i had no problem with it.The reason why i give 4 stars, it drains net, i have a slow network if we use so many tabs they shows like that this extension make tap to close. So no other problems,,, i prefred to my friends also...
Thank You...

this is my favorite add-on/extension, i love so much and it does it's job well helping your eyes out.

Thank you so much ma dude ;P

Normally, I use light theme.
When using the Dark Reader, it is correct that everything is dark.

But when off using the Dark Reader, my theme is still dark, although should return to light theme as before.

I really like the add-on, it does exactly what it says it does, and does it very well. It gives sufficient controls to configure, and selectively customise or disable the add-on on specific websites.

That said, I disabled it today after trying it for almost 4 months. Sometimes it slows down webpages too much, specially long pages (e.g. Github's webhook payload docs page), pages with visualisations (plots and figures, e.g. the coronavirus monitoring page by worldometers), and sometimes login pages.

I also have a hunch it's causing the memory footprint of my FF instance to bloat. I have a really beefy laptop (>13 gigs of RAM available), and it still starts paging after half a day. I do have a lot of tabs open, but I didn't have this issue before. If I continue to have my RAM issues after disabling the add-on, I'll come back and remove this paragraph.

Edit: now I have been running with the add-on disabled for half a day, with the same set of tabs, and my memory footprint is about 1/3-1/4 as before. Really sad that I can't use this add-on, back to being blinded on the Interwebs :(

Dark Reader works beautifully on Android, however I need to manually turn it on instead of relying on Auto button. My phone turns on dark theme at night and other apps do follow except for this one. I'm not quite sure if I'm missing something.

Thank you for making this.

Muy buena extensión
