We will not fix this in Firefox 68, but if you can confirm that his same issue happens in Firefox 79 or 80 (Fenix) then please let us know and we will move it to that project for assessment. You can try by downloading Firefox Beta, which is Fenix 80.

My experience was different from the reporter's:

• on Fennec (Firefox for Android 68.x) I can easily hit the "X" to stop the page reloading -- it flickers between loads
• on Chrome the browser is locked up solid
• on Fenix (Firefox for Android 79+) the browser is locked up solid (like chrome)

I couldn't find "Safari" on Android to compare :-P

Moved to https://github.com/mozilla-mobile/android-components/issues/8166 but it may move back to the GeckoView component.
