199083 - Mozilla is less responsive under a tab that is loading a page than one that is not

Status: RESOLVED WORKSFORME

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Moti Nisenson]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3) Gecko/20030312
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3) Gecko/20030312

Mozilla is less responsive when using tabs, when the currently active tab is
"loading" than if it has completed loading.

Reproducible: Sometimes

Steps to Reproduce:
1. Open a page and let it finish loading.
2. Open another page (good example site:
http://stats.zerothelement.com/cgi-bin/distributed-folding/render-team-detailed.pl?Id=10)
2. Let the page finish loading.
3. Middle click/control click a few of the links in the menu on the right (e.g.
Current Teams User Stats, All Users Stats, and All Teams Stats). Do this in
rapid succession.
4. Close the current tab (quickly) by right-clicking on the tab.
5. The current tab should now be "loading" one of the pages.
6. Press CTRL-T to open a new tab.
Actual Results:  
Nothing

Expected Results:  
Opened a new tab.

Mozilla will open a new tab later, it's just unresponsive for a couple of
seconds. This doesn't seem to happen when the current tab isn't in the loading
state.

Reporter, do you still see this problem with the latest nightly (or even 1.7.3)?
If not, this bug has probably been fixed and can be closed. Thanks.
