@dusky186 MD works well on my 2017 kindle fire, reload if I'm loading too many multiple pages at once, yes, but very rarely crashes. I'm not tech savvy but you should check on your phone's RAM, what kind of mobile browser, running any addon or auto utilities apps (they do interfere with apps' performance, back in 2012 I used this cleaner app and my games kept crashing, turned out the auto-maintenance feature messed up games run) etc. Might be a good idea to reinstall browser apps or at least fully clean it once in a while as sometimes updates can actually break the browser.
