Freezes on Firefox Android

[davidchoo12]

Opening busrouter.sg on Firefox Android will work for a few seconds before the tab stops responding. Opening new tabs will only show a black screen and will not load any webpage entered in the address bar. Even killing and restarting Firefox does not fix it. Only after some indefinite duration of not using Firefox after that, then Firefox can work again. It happened to me at least 5 times already but I did not investigate further what causes it or what fixes it. The website works fine on Chrome Android.

Firefox 84.1.4
Android 7.0

I've tried it on my phone (Firefox 84.1.4 on Android 11, Pixel 3), seems to work okay so far.

From your description of the bug, it seems likely a Firefox issue. Tabs stop responding and opening new tabs showing black screen etc are bugs that are outside the scope of what a web site can do. Especially when the site works on Chrome Android but not Firefox Android, makes it more obvious.

Few solutions that I could think of:

• Try out Firefox beta and see if the issue persists?
• Report the bug to Firefox devs?
• Maybe try out other browsers besides Chrome and Firefox, to further check if this is just a Firefox problem.
