User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b8pre) Gecko/20101105 Firefox/4.0b8pre
Build Identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b8pre) Gecko/20101105 Firefox/4.0b8pre

I am noticing a performance degrade between today's Minefield build and yesterday's (11/4).  When I was filling out job forms on Indeed.com, I only had about ten tabs open and Firefox was becoming unresponsive as I was trying to copy and paste my resume in text boxes on the sites.  Also, when I searched for bugs in Bugzilla today, I noticed the animated dinosaur was not smooth and was stuttering (yesterday it was smooth with the 11/4 build).  I have 4 GB of RAM on my computer and Minefield is only using about 220 MB right now.  Also, Minefield froze when opening a PDF document (http://www.thinknts.com/uploadedFiles/Site_2.0/Careers/NJ2333.pdf).  Finally, I am just changing from one tab to another and Minefield will stop responding for up to ten seconds. 

Reproducible: Sometimes

Steps to Reproduce:
Difficult to reproduce - noticeable performance degrade.  Minefield would stop responding as I was entering information in job forms.
Actual Results:  
Noticeable performance degrade from yesterday's Minefield build (11/4).

Expected Results:  
Minefield should not stop responding and hesitate as I am copying and pasting text.

Concerning the Forms, there were some Checkins In Editor Component.
Can you narrow the Issue down further using Hourly Builds?

I just downloaded all nine of the hourly builds one-by-one for 11/5/10, ran Firefox and did not notice any performance drops.  I also downloaded and installed the latest Minefield again (11/5/10  05:38) and did not notice any issues.  Maybe it wasn't Firefox / Minefield that had the problem - maybe it was Windows.
