Browser freezes; doesn't display Unresponsive Script warning

Firefox 35.0a1 (2014-09-06) • Adblock Plus • EasyList Hebrew+EasyList • Adblock Warning Removal List

How to reproduce

  1. Go to any article page on, e.g.,7340,L-4567961,00.html
  2. Wait a few minutes (2–3 on my system).
  3. Since EasyList Hebrew may update by the time you read this, I'm including a list of all filters currently applied to the page:\.300x600\.1,,,\.top[style="width:300px; background: #000066;"] + .element.B3.ghcite + .element.B3.ghcite + .element.B3.ghcite + .element.B3.ghcite

Observed behavior

The browser freezes: the window is dimmed and "(Not responding)" is added to the end of the window title. Firefox doesn't display the "Unresponsive Script" warning at any point.

Expected behavior

Presumably, Firefox should've displayed the "Unresponsive Script" warning that would've allowed to continue browsing.


Please don't reflexively dismiss this is a filter problem. The issue here is that Adblock Plus should never cause Firefox to freeze, regardless of filters. If there's a different problem here than a script gone haywire, or some technical reason why the "Unresponsive Script" prompt can't show in this case, please explain.

  • Resolution set to rejected
  • Status changed from new to closed

Mass-closing all bugs in Adblock Plus for Firefox module, the codebase of Adblock Plus 3.0 belongs into Platform and User-Interface modules. Old bugs are unlikely to still apply.
