happened to me too more than twice …

yandex Browser which also support every Chrome desktop extensions(looking at you ublock …) on Android has this feature glad to hear I’m not the only one I use it.

unfortunately dark reader makes Firefox too slow let’s use stylus or https://github.com/m-khvoinitsky/dark-background-light-text-extension

give nighlty I try on my second old phone were Firefox was not usable is now working quite well (for the old hardware snapdragon 660 and 4 giga of ram )the only sad part is opening or focusing url bar (which still show home )is painfully laggy and slow
