Description

*Technical Specifications*
OS: Linux 32 bit (Debian)
Browser: Tor Browser Bundle 2.3.25-2
Browser Addons: Adblock Plus with Easyprivacy+Easylist

I noticed that starting from Tuesday, January 16 2013, I have been unable to scroll on any Twitter or its child pages using the arrow keys. The "Pgup/Pgdn" buttons do not work either.

NoScript shows that it is blocking a "java-vm" object on Twitter and its child pages. I am not sure if this is related to the scrolling issue because I have noticed that the "java-vm" object has been present for a few months now (while I was still able to scroll with no problems).

I logged into Twitter from Firefox 18.0 and was able to scroll without any issues. There was no indication of a "java-vm" object on NoScript either.

If you need any further details, I'll be glad to provide them.

Update: I tried this on a clean TBB install (no addons other than the ones installed by default) and the problem still persists.

A description of the weird scrolling behavior: When I press the "left" arrow key, the page scrolls to the bottom, then the "down" arrow key works until I reach the bottom of the page, at which point, it jumps to the top of the page.

Update as of Feb 17, 2013:

  1. I tested this on TBB Alpha F17 and the problem doesn't exist there. I am able to scroll using arrow keys and NoScript doesn't indicate a blocked "java-vm" object.
  1. On TBB Stable, I looked at the error console and this is what it shows:

Error: uncaught exception: Error: Permission denied for <https://twitter.com> to get property Proxy.InstallTrigger

Error: wouldMatch is not defined
Source File: chrome://https-everywhere/content/code/HTTPSRules.js
Line: 659

I guess when F17 becomes stable this problem goes away. I will keep it open until then, though, just so that you can see the messages in the error console if you find it interesting.

Twitter scrolling works for me. Try starting from a fresh TBB directory and adding things until it breaks.
