I visited gmail.com, google.com and www.mozilla.org/projects/minefield, however I don't think the webpages were the cause. Upon uninstalling weave and closing the browser, DOM leaks were gone. I DO NOT have user information entered into weave, that could be the cause but it probably shouldn't leak at this point anyway. 

This is my first time making a bug report, let alone a memory leak bug report, I'm re-reading DBarron's post on making good memory leak bug reports as I'm writing this but will update it if I realized I missed something. Be gentle and let me know if i need to include more info.

Heres the results of leak-gauge.pl analyzing the log:

Leaked inner window 1525070 (outer 14ad9c0) at address 1525070.
 ... with URI "about:blank".
Leaked outer window 14ad9c0 at address 14ad9c0.
Summary:
Leaked 2 out of 22 DOM Windows
Leaked 0 out of 64 documents
Leaked 0 out of 9 docshells



Reproducible: Always

Steps to Reproduce:
1. Install Weave
2. Start firefox in cmd using (make changes of course if your directory for firefox is different):
set NSPR_LOG_MODULES=DOMLeak:5,DocumentLeak:5,nsDocShellLeak:5
set NSPR_LOG_FILE=C:/Program Files/Minefield/nspr.log
start "Firefox" /wait "C:\Program Files\Minefield\firefox.exe"
3. Analyze using leak-gauge.pl after closing firefox using:
perl "C:\Program Files\Minefield\leak-gauge.pl" > "C:\Program Files\Minefield\nspr_leaks.log"
4. See results of memory leak
5. ...
6. Profit?
Actual Results:  
Leaked inner window 1525070 (outer 14ad9c0) at address 1525070.
 ... with URI "about:blank".
Leaked outer window 14ad9c0 at address 14ad9c0.
Summary:
Leaked 2 out of 22 DOM Windows
Leaked 0 out of 64 documents
Leaked 0 out of 9 docshells

Expected Results:  
Leaked 0 out of 22 DOM Windows

Does this still happen?  A lot has changed since december, could you re-test?

I turned on weave right after installing FF 3.0 release.  After doing the sync and going through 1-2 websites, FF grew from 80mb of memory usage to 120 and continued to climb until I had to kill the process.  It was also using 100% of the cpu.  

This is as of 2 days ago with 0.1.30 and 3.0 release.

The only thing different from default is, in configuring weave I did turn on all the sync options.  I had 3 clients all installed with weave and subscribed to the same account.
