I've been using Firefox on Android for about a year now, and it is great, except one major problem. Google news site (news.google.com). News I believe uses my entire phone's RAM and starts swapping (I am totally guessing, does Android use swap?) because the app will become unresponsive for about 2 full minutes while the page is rendering. Closing and re-opening a tab in this state actually breaks the app FYI (all other tabs freeze as well). Scrolling will give low resolution visuals below the fold. Horrible experience on google news. Actually all google properties are PAINFULLY slow. Is that on purpose Google? I got around it by installing Firefox Focus, and that seems to load google news quite fast, but Focus is like a permanent incognito mode, so that is quite inconvenient in itself. So now I just use Focus for google news and regular Firefox for everything else. Hopefully there will be performance improvements to come. My phone is an older Huawei Honor 8 so maybe I should just buy a new one... but the infrared on it is so great!
