This is a page for tracking the work on improving the startup performance for Firefox 3. It should list the main items that are being researched or that need to be researched, names against those in progress and where we think we can make useful improvements, bugs tracking the fixes.
XBL Simplifications
Tabbrowser
- Kill off the theme specific bindings and control minor differences with CSS
- Kill the close button binding
- Try to use plain widgets where possible (eliminate extensions)
XUL Reduction
http://groups.google.com/group/mozilla.dev.apps.firefox/browse_frm/thread/6db1639b028850f5/
Toolbars
- Remove endcap stack hack - bug 387646
Searchbar
- Remove engine button stack hack (Ryan)
Tabbrowser
- <tab>s are 10 levels down from <tabbrowser>
CSS Optimizations
http://developer.mozilla.org/en/docs/Writing_Efficient_CSS
General Quick Gains
- Except in rare cases, any use of the universal selector is wrong!
- Many descendant selector uses are unnecessary and can be refactored to use the child selector or (if applicable) have the targeted element inherit attributes from its parent.
Tabbrowser
- Clean up leftovers from tabbrowser move - bug 393734
