Ideally, all websites should be respectful of the limits and speed of bandwidth and processing power available for mobiles and limit ads. Unfortunately that's not true. And that's not in our control.
The next very best solution is to install Firefox. Then add UBlock Origin. Now all the websites are fat trimmed and lean. I often endup having 200 pr more open tabs on mobile and it has never been a problem (Open tabs double as ToBeRead list) . May be it has crashed twice in the past 2 years. I have never lost a tab during the crash, a power failure or a restart. Always quite fast.
Actually it makes a lot more sense to have Firefox on Mobile than the desktop as it is the only browser (as far as I know) that allows you to block ads.
I should have been more explicit. The ads redirect to a new page and continue to redirect when you hit the back button, making reading the site impossible unless you manage to tap “reader mode” in the ~1s before the ads kick in.
Happy to be of help. People behind works like Firefox and Ublock Origin have done so much. Using their work is just another form of recognition that they so richly deserve.
