Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.5) Gecko/2008121622 Ubuntu/8.10 (intrepid) Firefox/3.0.5
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.5) Gecko/2008121622 Ubuntu/8.10 (intrepid) Firefox/3.0.5

There is an apparently memory leak when viewing Best Buy's website (http://www.bestbuy.com/) in Firefox.  When I load this website and then leave Firefox alone, memory usage grows indefinitely.  This occurs in version 3.0.5 (both Windows and Linux versions) as well as in the latest nightly Windows build.  This appears to be JavaScript related, as the memory usage does not appear to grow if I disable JavaScript and load bestbuy.com.

Reproducible: Always

Steps to Reproduce:
1. Access http://www.bestbuy.com/
2. Watch memory usage grow.
3.
Actual Results:  
Memory usage grows indefinitely.

Expected Results:  
Memory usage is stable.

Can't reproduce this. Have you tried this in safe mode http://support.mozilla.com/en-US/kb/Safe+Mode and with a new profile http://support.mozilla.com/en-US/kb/Basic+Troubleshooting#Make_a_new_profile ?

I still appear to be able to reproduce this with the Windows trunk version in safe mode and with a new profile.  I did the following:

1. Ran 'firefox.exe -ProfileManager' and created a new profile, 'NewProfile'.
2. Ran 'firefox.exe -safe-mode -P NewProfile'.
3. Entered 'http://www.bestbuy.com/' in the address bar.
4. Watched firefox.exe in task manager.  It started at around 43MB and grew to approximately 78MB after 5 minutes.

Natch, did you have JavaScript enabled when you tried to reproduce this?

Yes but I didn't wait for 5 minutes :/, I'll test this again later.

I'd say this is result of the flash image and is bascially WFM. If you instsall flashblock extension, with the one flash image running you should see memory fluctuate 30-40MB which would not be unusual.  With flashblock and the flash image not running I see no fluctuation.  If you agree, please close WORKSFORME

my testing was with  http://www.mozilla.com/en-US/firefox/all-beta.html
and flashplayer v10

I no longer am able to re-create this problem.  I suspect Best Buy changed something on their website, as I went back to Firefox 3.0.5 and was unable to re-create the problem with that version either.
