Description

Some people report black boxes occurring when the page is scrolled. They obscure part of the screen and make the site (almost) unusable.

One account is from the forum, with a video of the issue included:

So if everyone who is having this issue could post a little note about what kind of hardware they are using and which version of Android, I would really appreciate it. I'm trying to replicate the issue but am not able to.

Nexus 4, Android 4.2.1. I can easily reproduce this on Firefox 17, but not Nightly.

HTC Desire HD, Android 2.3.3 and Firefox 17.0.1

Nexus 4, Android 4.2.1, Cyanogenmod 10.1 20121231-NIGHTLY-mako:

Firefox (17.0) - Reproducible every time.
Firefox Beta (18.0) - Not reproducible.
Aurora (19.0) - Not reproducible.
Nightly (20.0) - Not reproducible.
Chrome (18.0.1025469) - Not reproducible.
Browser (Native) - Not reproducible.

This feels like a browser bug to me, but one that we should look into. If nothing else, it should get better when beta become stable.

Firefox 18 came out today and doesn't have the issue.

Swarnava, could you please verify if updating to Firefox 18 solved it for you?

If anyone is still interested, this seems to be an issue related to physical memory and how much is available, or rather how much is lacking. Other browsers just crash, like Opera or Chrome.
