*My 'Firefox for android' app's "User Data" has increasingly become 374MB only because it loses track of "Incognito sessions" each time when this app is abruptly closed by the Android System (due to low RAM / or for battery saving). This app is currently not smart enough to auto clear the junk data of private browsing sessions' abrupt closure. An update must be brought as soon as possible for this issue. So that our history & data retains, but only junk/old private sessions' data are cleared from storage.
* While editing Text in this browser the auto "Magnifier" setting toggle to turn it off should be provided in settings.
