Je n'ai jamais eu rien à redire depuis que je l'utilise, c'est-à-dire + de 5 ans mais depuis la récente mise à jour je ne peux plus utilisé Dark Reader pour naviguer dans les menus, barre latéralle et personnelle de Firefox. Ça rend tout noir, seul les icônes reste visible.

Completely breaks Firefox and Firefox even tells me that the extension is slowing down my browser. It makes websites completely unusable for a few minutes each time a page loads.. Please fix this.

Cheers to the developer team for keeping us updated with the issues the latest FF update caused. Been using this extension for years both at home and at work and it's saved my eyes and sanity. Cheers, guys!

4.9.99 destroys Firefox more than it does good despite the tips cited below. I went back to 4.9.98 and everything is back to normal. You need to review your copy.

The best dark reader extension available - outstanding work! Ignore the recent 1-star reviews about Reddit's website - the bug was introduced by a recent update by Reddit itself, and the Dark Reader developers quickly worked to address the issue.
If you're a (long-time) user of this incredible tool, please consider supporting the developers through a donation to help them continue their fantastic work. It's discouraging (and counterproductive) to see users who have benefited from Dark Reader for years suddenly leaving negative reviews at the first sign of a problem, instead of reaching out to the developers or checking for updates first.

This is one of the most vital and effective add-ons I've ever installed. Not every website/browser/etc has a consistent dark mode, and none handle it as well as Dark Reader. Needing to constantly research, this add-on saves my eyes at night. Even with recent changes to FireFox which temporarily hampered performance, Dark Reader quickly pushed an update and is straightforward about addressing issues. Honestly, this is probably one of the best add-ons next to an ad-blocker out there.

This extension is a huge difference maker for me, and for so many people, reducing eyestrain and promoting eye health. The internet is always changing and squashing bugs is a constant battle. So thank you Dark Reader for your hard work!!!
I want to contribute some encouragement and I will contribute cash as soon as I'm able.
Edit: For users who may need to disable this on a specific website: First, go to the website where you're having issues, then open the extension menu (you should see only your active extensions). Select Dark Reader, then uncheck "Enabled for current website". The menus are different between desktop & mobile, but it's fairly easy to figure out.

really a must-have addon if you don't want your retinas to be burnt to a crisp on a daily basis. i'm rating it 4/5 because it has helped me for so long, but sadly the past days its been having issues with youtube to the point where i can't have it activated at all for it.
every time i try and activate it and refresh youtube homepage, the browser is about to crash and it asks me to stop this addon specifically. when i pause the addon, it works fine and i can refresh youtube without the browser almost collapsing.
were this to be fixed, then its an easy 5/5 for me.

Not works on Mozilla.org page. All other perfect

Thanks Dark Reader team for taking care of our eyes.

To those with v4.9.97 breaking Firefox: Just realized that the Developer's note applies to Settings on DarkReader, not Firefox. Go to the DR icon on the top of your window and choose "MORE". It is to the right of "Filter". Then choose "Default" below.

It was relatively good until today, when it was automatically updated, and now I cannot see the bookmarks in the bookmarks sidebar, nor the menu bar. All is just black, except for the icons for the bookmarks in the sidebar. It became useless. And your answer to Tikitaki makes no sense, as there is no "custom browser theme" option to be disabled in the "General" settings.
PS: I figured it out. I thought that in your response to Tikitaki, you were talking about the Settings in Firefox, when you were talking about those of Dark Reader itself.
So here is how it should be explained:

Open the settings of the Dark Reader > Click the "More" tab > Click "All Settings" > Click/toggle "Change Browser Theme" so that it says "Default browser theme is active".

If you want some custom browser theme, install it or enable it AFTER all this procedure through Firefox Themes settings. You actually may need to uninstall and reinstall the Dark Reader extension and revert to the default Firefox browser theme in the Firefox settings before all this.

I will leave the comment with one star for some time here, to help those who might have the same problem.

With last update I got blank black window and menus in firefox
Update: disabling custom theme solved my problem, thx!

It slows down Firefox now. So sad
