Very very great for low visionusers!!!

It makes pages dark, but yet readable. It does slow FF down a bit loading pages as it has to parse them, but it does a GREAT job on pages. Love it!!!

You can take care of eyes.
You can save mobile phone's battery.

Installed it last evening, and it worked well except for the occasional popup saying that it was slowing down my browser. I turned it off this afternoon, and tonight I reactivated it. Immediately my whole browser freezes, and then even windows hangs and it becomes completely unresponsive. Not even CTRL+ALT+DEL worked, and I let it chug for 5 to 10 minutes. Had to kill the power.

Never had a browser add-on crash my whole computer, so unfortunately I have to give this 1/5 stars. If it had only had the few but noticeable slowdowns it would've been a 3½ / 5, and if no slow-down warnings at all, 5/5.

your add on is very intresting and very good. I like it and i start to use it, for now ,,,
as you already know, sometimes the code become heavy,
in some weak devices, or
in sites that are already heavy, by inject too much js code to the user.
Because of this last, and because most of the sites, start to become like this ( i mean put the
user to build the page, and not the server => thats why our browsers seems so incapable some times,
and take the CPU/Memory and create big swaps (but this is another discussion),
i want to share some ideas.

1. there you have your tabs background / images / texts /.... ,
give an option to disable any of them. So later your js to have less work.

2. This will work, In sites that have somehow very similar CSS selectors across their pages.
instead to inject class to query selectors through JS, compile a CSS by the 1st page of the site,
and then just inject the style, after the page load. I believe in facebook, youtube this will work
quiet well, and give an option to the user (maybe in Common section) to use this mode.

sorry, for my big review. Nice work !

Cooool!

This app is insanely useful, and works on every website i've tested. My only complaint is that it's a hard to use at first, and when changing values, it'll take a few seconds after pressing apply for your results to show up which is annoying when you want to fine tune a page to your liking.

Excelente Extensão

So great for my visual impairments and easily readable and convenient to locate information even at night in the car. I love Mozilla Firefox!! Best browser EVER!!

Thank you
it is One of the best dark mode add-on.
Please add right click context menu command to enable/disable it.

Thanks a lot, this was much needed

Incrível como deixa as paginas pesadas, não vale a pena.
