When i use all of my internet limit it limits my internet, on firefox websites are unusable. Is there browser for android with following features:
Preferably on F-Droid
Just load text
Edit:
For now solution is firefox + ublock (adnauseum) and in settings of ublock check block JavaScript and block elements over 10kb


Thanks, I used it with adnauseum and it made internet slightly more bearable.
But I reduced max loading element size to 10KiB
Does anyone know how to make it load later these elements
For example load first elements with 1kb later 10 kb next 100kb etc.
Adnauseum is the opposite of bandwidth saving in your case. It sends a request to ad trackers reducing the impact of your the data usage reduction.
Remove Adnauseum and switch to Ublock-origin. 64kbps was a data speed I think I saw in 2010/2012 and maybe, 2014 when I used to exhaust my data limit.
You need every data saving measure you can get. I would block 3rd party requests if you haven’t already to reduce the bandwidth needed even further.
