Description

11 years ago
User-Agent:       Mozilla/5.0 (X11; U; Linux i686; nl; rv:1.9b5) Gecko/2008041514 Firefox/3.0b5
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; nl; rv:1.9b5) Gecko/2008041514 Firefox/3.0b5

When I load a web page containing much data during a couple of seconds firefox hangs en is unresponsive. Sometimes this happens when nothing is active but primary when something is loading. If I click the wrong hyperlink I can't correct it because firefox is hanging untill the new page is loaded. 

(tested on ubuntu hardy firefox 3 beta 5)

Reproducible: Sometimes

Steps to Reproduce:
1. Start firefox
2. Load a heavy webpage
3. Click the inteface or the document, unresponsive and slow. 
Actual Results:  
Firefox became slow for several seconds (very irritating and frustating) and buttons and hyperlinks didn't work. It seems that especially large images can break firefox 3's performance. 

Expected Results:  
unresponsive firfox

Have you been running any processes with lots of hard disk io (apt-get upgrade, trackerd, software compilation, ...)?
If so, this might be bug 421482.
You can check by calling
   strace -f -tt -T -e trace=fsync -p `pgrep firefox-bin`
The last number in each line shows the time firefox spends waiting for fsync.

@Reporter, we have not heard back from you in a while, so I am closing this bug as INCOMPLETE. You can reopen this bug if more information becomes available. Some helpful information you can provide us is found at http://quality.mozilla.org/bug-writing-guidelines. You should also use a recent version of Firefox, from http://www.getfirefox.com.
