Do you by any know an extension for Firefox based browsers that doesn’t slow them so much as original extension?
One of my devices is really slow (5 yo tablet with eMMC 
) and using Fennec or Ironfox is pain on it. Two smartphones are bit better, but noticeably faster. UFS, better SoCs…
Is there a faster extension for dark mode than Dark Reader?

El hecho es tal y como lo percibes: el add-on Dark Reader es eficaz, pero ralentiza demasiado la experiencia de navegación con cualquier «Firefox».
Prueba con el add-on Super Dark Mode 5.0.2.5 a ver qué tal. Es el que uso, sobretodo, para tratar de leer textos en pantalla de forma más relajada. Funciona bastante bien y, aunque no sea perfecto, considero que no frena la navegación (admitiendo la comparación con Dark Reader).

The fact is exactly as you perceive it: the Dark Reader add-on is effective, but it slows down the browsing experience too much with any Firefox.
Try the Super Dark Mode 5.0.2.5 add-on and see how it goes. It’s the one I use, especially to try to read text on the screen more comfortably. It works quite well, and while it’s not perfect, I don’t think it slows down browsing (allowing for a comparison with Dark Reader).

I second it. I used it very often and even on newer phones or high resource phones too it slows down the scrolling or switching. Moreover, at times it freezes FF & forks if there are number of tabs open.

Tried Super Dark Reader, Dark Mode,Turn off the lights, Night eye, but UltimaDark seems really work fastest and reliable of all of them.
Tested on browserbench.org, speedometer, where the order of speed was: Iceraven, Fennec, Ironfox - from fastest to slowest.
What worked really fastest was DDG with it’s built in dark mode. What you think about moving to that browser?
All Fennec, Iceraven, Ironfox were 2-4 slower in that test.
DDG Lite if you want to use, okay, but do not go for full ddg. It is not safe. You can find more about it on this forum as well as several other places.
Haven’t found anything of DDG lite browser, only of their ddg lite search engine.
Ahh yes. My bad. I confused between the browser & engine.
BTW, you can use Lightning Browser (by Anthony) or any other lighter browser tbvh. You can even use a scraper as an engine and not just DDG Lite in itself.
My little but time consuming inquiry about the speed of browsers with dark mode on 5yo tablet Lenovo Yoga Tab with Android 13, LineageOS.
All *fox had only uBlock and UltimaDark enabled, except DDG, which doesn’t need it.
In order from slowest to fastest.
Ironfox
Fennec
Iceraven
DDG.
Ironfox is so “secure” that it didn’t even let me install extension and run the test without disabling some hardening features.
My conclusion is that securing browsers goes towards some like locking up oneself in home jail, because going out you may hurt yourself, when you slip on the ice, stumble and fall…

Lo siento, no puedo confiar en los «Test de Velocidad» que has hecho. No porque los hayas hecho tú y dichos test puedan estar bien o mal realizados. Si no porque los «Test de Velocidad» por si solos no me dicen nada de nada. Ya que la velocidad de transmisión de Internet está comprometida por varios factores de instante en instante.
El comportamiento y la eficacia de una aplicación (con o sin add-ons o extensiones) también se ve comprometido por diversos factores… Así que, la mejor prueba definitiva de lo bien o mal que funciona una aplicación, sólo la tendrás observando el resultado de su uso en tu dispositivo.
Otra cosa bien distinta pero relacionada, es la manifestación de un «Fallo de Funcionamiento Universal». Es decir, cuando en una aplicación se da un fallo concreto que puede ser observado en cualquier dispositivo Android, con cualquier Sistema Operativo y bajo idénticas circunstancias de configuración. El caso tan reciente que me trajo hasta el Foro da buena prueba de ello (ningún “Fox” actual interactúa eficazmente con los add-ons para descargar contenido web).
Sobre los add-ons para oscurecer las pantallas que has probado: los probé todos en su momento y el más eficaz está claro que es Dark Reader en cualquiera de sus dos versiones. A cambio, eso sí, como ya hemos hablado, de pagar el precio de una evidente (¡e insoportable! 
) ralentización de la navegación.
De todos esos add-ons que has descubierto, sólo me funcionaron Dark Reader/Dark Mode y Super Dark Mode (by Arturito Roman). Así que me alegra que hayas encontrado la eficacia que buscas en el add-on UltimaDark (by ThomazPom) o en el add-on Dark Mode Ultimate (by Cool Addons).
Aún tengo que darle otra oportunidad a todos los Oscurecedores que llaman mi atención, para ver si han mejorado y debo sustituir ya a SDM por otro más eficaz.

Sorry, I can’t trust the «Speed Tests» you performed. Not because you performed them yourself and said tests could be correct or incorrect. But because «Speed Tests» alone don’t tell me anything. Internet transmission speed is compromised by several factors from moment to moment.
The performance and effectiveness of an application (with or without add-ons or extensions) is also compromised by various factors… So, the best definitive proof of how well or poorly an application works, will only be obtained by observing the results of its use on your device.
Another very different but related issue, is the manifestation of a “Universal Functional Failure.” That is, when an application experiences a specific error that can be observed on any Android device, with any Operating System and under identical configuration circumstances. The very recent case that brought me to the Forum is a good example of this (no current “Fox” interacts effectively with add-ons to download web content).
Regarding the screen-darkening add-ons you’ve tried: I’ve tried them all long ago and the most effective is clearly Dark Reader in either version. The price, however, as we’ve already discussed, is a clear (¡and unbearable! ) slowdown in browsing.
Of all the add-ons you’ve discovered, only Dark Reader/Dark Mode and Super Dark Mode (by Arturito Roman) worked for me. So I’m glad you found the effectiveness you’re looking for in the UltimaDark add-on (by ThomazPom) or in the Dark Mode Ultimate add-on (by Cool Addons).
I still need to give all the Darkening add-ons that caught my eye another try, to see if they’ve improved and I should replace SDM with something more effective.

Please notice 2 things:
- You’ve misunderstood what I exactly did
I didn’t post internet speed tests, but browser benchmarks. You can read how Speedometer works on browserbench.org. Everything is described there. In general Speedometer simulates browser usage by automating some things to be done on browsers by people, and that overall scores is much of a data for me. We’ve been comparing them with few friends of mine, regarding different devices, and results were… Interesting. - Those tests are much more valuable than opinions to be read on the “internets”, like “this browser is slow, that is fast”. If i meet those opinions repeatedly many times, I may take them to account too, but as never more important than raw data you can show others or just my own experience.
I’ve performed Speedometer dozens and dozens times during last months since last autumn.
I’ve done them for curiosity and learning purpose, for proving something and for choosing best browser for me as well.
Also, I’ve done them on many, many browsers that I’ve considered worthy (leaving Mi browser thrash or opera thrash behind), even the ones that died soon later (Kiwi, Mull etc…) including Brave, Vivaldi, Edge to compare Blink based to Gecko based.
Conclusion, that might have been obvious for some people was just that: all Blink based are faster that Gecko based, but… to hell with that! 
I WILL NOT drop Firefox (or rather it’s clones) 
Btw. Just a mention that in the meantime I’ve found very interesting alternative for Waterfox on PC, that I’ve been using before autumn 2024 - Zen-browser. It was developed really fast and came with so many features that it was even too much for me.
Give it a try 
I’ll probably do it too in the spare time, if UltimaDark fails, but Dark Reader failed on speed too much.
Thx for pointing me the names, some rankings and opinions on Mozilla add-on site are just unreliable.
I’m sure I’ll be back in this thread
