317965 - Firefox hangs when loading a web page from a slow site

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[vexx01011]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7 (ax)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7 (ax)

If a website had poor bandwidth or is under a heavy load causing web pages to load slow due to the lack of bandwidth, firefox will hang until that page is finished loading

it happens on many websites. forums.g4tv.com  www.tigerdirect.com all sites that have limited bandwidth.



Reproducible: Always

Steps to Reproduce:
1.go to www.demonoid.com, or http://torrentreactor.net/
2.search for anything 
3.using the mousewheel to open in new tab, open a few tabs
4.firefox will hang (not responding to any clicks or anything) until those pages are finished loading

Actual Results:  
after doing the steps, you will see that firefox will become inresponsive to anything (hang) until the pages are finished loading. and if the pages don't load due to the site dropping a packet or crashing, then firefox will stay hung until you  ctrl alt delete and close it

Expected Results:  
 What should the software have done instead of hanging? it should have waited to load the pages with out hanging so i can do other work while the pages are loading.

i have a 18Mbit/s dsl fios connection

amd athlon xp 2600+ 1 gig ram, in windows xp pro, i am fully msconfig tweaked only 13 running processes when firefox is opened. (the tweak gives me a major speed bost in all areas of computer use  and best of all, it will greatly increase your FPS when gaming.

WFM

Can't reproduce this on the pages you quote. Can you try with a more recent version of FF?

I see a similar behaviour very often. Just like bug 159672 says: "If the user is loading the tabs in the background, they would like to continue to browse the foreground tab. By becoming unresponsive chimera is preventing the user's desired behavior." Although, this applies to Firefox 1.5.0.6 too. And has for a long time.

Reporter, do you still see this problem with the latest Firefox 2? If not, can you please close this bug as WORKSFORME. Thanks!

Comment 4

[Roman R.]

I am not the reporter, but I can confirm that this behavior still happens often... never stopped, and I'd really like it to be fixed. But I suspect it will never be done until each tab works in its own thread.

WFM with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b5) Gecko/2008032620 Firefox/3.0b5.  I opened 9 tabs from torrentreactor.net in the background as quickly as I could, and I was always able to scroll around on the first torrentreactor page, as well as switch to other open tabs as the 9 pages were loading in the background.

Reporter or Roman, do you still see this problem with the latest Firefox 3 beta?  If so, are the STR above still valid?

this problem was actually fixed with firefox 2

it can still happen with excessive use of tabs but thats more of a limitation with firefox not making good use of all 2 cores.

Comment 7

[Samuel Sidler (old account; do not CC)]

Resolving as WFM per comment 6.

Comment 8

[Roman R.]

It seems better now. I'll keep an eye for this problem.

inuyasha6332, is there a bug issue in which fixing this problem is documented?

Comment 9

[Roman R.]

It still happens. Here's a good example (for now, at least): go to http://forums.expression.microsoft.com/en/web/threads/ and choose a thread with a large number of messages and open it in a background tab. And while it's loading, try scrolling content in the current tab. I see it hang all time. Now, I don't have to kill Firefox to start using it again. I just have to wait for the background tab to finish loading/rendering.

So, Samuel, you were to quick to mark this as resolved.

opened like over 100 tabs and it did cause firefox to hang for a while 

i recorded a video of it and uploaded it to youtube

IS on the old 2600+ firefox 2 had less lag than with 1.5

i am now on a dual core opteron 170 system

the lag problem is mainly due to firefox not being able to use both cores

here is the youtube link

That's an interesting observation about the multicore support, but what I described was just with ONE background tab loading the page, and no more than 4 total tabs open. And I also have a dual core processor with 2 GB of RAM.
