249320 - Mem usage is not recovered - Goto 10 sites in many tabs - close all tabs - mem usage huge

Status: VERIFIED DUPLICATE of bug 131456

(Firefox :: General, defect)

Description

[Greg Blank]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040626 Firefox/0.9.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040626 Firefox/0.9.1

This is the exact same unbelievably horrible memory performance as in Mozilla. 
When tabs close up memory is NOT released - I often have 300 to 400MB of usage
from Mozilla and now I see firefox doing the exact same thing - I thought you
guys would fix this - Its frankly pretty outrageous.  I am checking the memory
in the task manager both by the Mem Usage and VM Size columns, and both are
ridiculous.
The more pages you continue to open and close - the worse it gets over time.

Reproducible: Always
Steps to Reproduce:
1. open about 10-12 rich web pages in multiple tabs and/or windows - cnn,
nytimes, etc etc
2. Close tabs/windows up - and just goto 1 measly bare page
3. Look at memory - i got about 80MB of usage, then I got close to 100MB, - you
can keep doing this

Actual Results:  
Mem Usage and VM Size columns in task Manager are both ridiculously high. This
causes eventual memory loss and over time the product EVENTUALLY freezes and is
unusable!  I then LOSE all the pages that I had open (if I hadnt bookmarked them
up to that point)

Expected Results:  
Go back to original memory foot print - or close to that since you still have a
page loaded.  I understand there is a mem cache by the product - but you should
be able to set that to what you want - like you could all the way back in
Netscape 3 - like 10 some odd years ago.

This causes eventual memory loss and over time the product EVENTUALLY freezes
and is unusable!  I then LOSE all the pages that I had open (if I hadnt
bookmarked them up to that point).

[Greg Blank]

Its very similiar BUT basically you are saying this bug HASN'T BEEN FIXED in TWO
YEARS across the general product line???  OMG!!!  The 1st reporting was 2 years
ago!  That's quite scary.

As an experiment, does IE behave the same way?

Comment 5

[Greg Blank]

No it behaves decent.  I loaded up about 30 windows with web sites - killed them
all off except one and went from about 135MB of usage back to 70MB, then I
opened 25 more (off the original one window) - it went back up to 135MB, and
then I killed them off again, except one, and it went back down to 70MB.  This
is fine with me.  If IE imlpements tabs then I would start using it again. 
Tabbed browsing is really the killer feature for me.  (Google toolbar, a hosts
file and spybot protects against popups and spyware).

I expected IE to behave well, after all, they know and understand the Win32 API
and the horrendous GDI.

Next experiment. How does Opera behave. It does have tabbed browsing (not that
I've used it much on Opera).
