Program Management/Projects/DesktopHangs

This is a working page to track all activities and analysis related to hang issues in the Firefox Desktop.

Background

• Currently there are 2 classes of hangs
  • There are plugin hangs which we catch and receive a plugin and browser side crash report.
  • There are browser hangs which we really have no visibility into.

Plugin Hangs

There are a number of things we are doing to track plugin hangs.

Bugs

• bug 651192 - Implement new AsyncDrawing model for plugins. This involves removing support for windowed plugins since they are the thing causing us hangs. Hangs don't happen with windowless plugins and we'd like everything to be windowless for other reasons as well. We can't really remove windowed plugins until we have an alternative and this bug represents part #1 of that.
  • Status: Talking to Josh, we made some progress on this but not much. Work will probably resume in another month of so.

Browser Hangs

We know less about the extent of problems when the browser hangs but we have several activities in the works to investigate this further.

Analysis

• bug 429592 - We are working on a patch to catch these types of hangs.
• Release Management is working on a project to investigate winqual reports that are generated when the user kills the browser.
• There are a number of bugs that relate to hang issues that we are investigating.
