Description

8 years ago
User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1) Gecko/20090624 Firefox/3.5 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1) Gecko/20090624 Firefox/3.5 (.NET CLR 3.5.30729)

When viewing websites that very long vertically, the whole program tends to lock up for a bit.  This is happening particularly in Easynews.com with long lists of stuff shown on the page, but it's happened elsewhere

Reproducible: Sometimes

Steps to Reproduce:
1.Load up a long page with a lot of links.  I mean a really really long page.
2.Navigate in and out of links from that page
3.Profit?
Actual Results:  
After a couple of minutes of navigating in and out of links and returning to the main page, the program will lock up for some time

Expected Results:  
Not lock up

At this point it's more of an annoyance.  The program will recover, but it slows down my porn!  I'm setting severity as major since this is a pretty basic use of a web browser

It would help if you could provide publicly accessible URLs where you see this issue. Other things that can help:
 - try in safe mode to see if the issue is not addon-related.
 - compare with Firefox 3.0 (or older) to see if that's a performance regression. And also with Firefox 3.6 to see if that's fixed.

If the page has a large number of checkboxes or other form elements this is a dupe of bug 477564.

See also some notes in bug 500103.

Country pages in the Wikipedia are slow. This happens when you resize them too small (horizontally).

Especially:

http://en.wikipedia.org/wiki/Samoa

You can even hang the Samoa page, by resizing precisely the wrong size.

This is true on both Windows and Mac versions. I see no difference in safe mode on either platform. Performance is worse in 3.5.2 than in earlier versions - used to lock up for a number of seconds, but then recover. I've updated both Mac and Win to 3.5.2, and now I get a permanent hang (I run out of patience after 5 minutes of waiting, so that's my limit on "permanent". The hang will also happen if you force the app to quit, and then it tries to restore the session on the next startup - even if Easynews is just in a tab, not the open page
