User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050421 Firefox/1.0.3 (Debian package 1.0.3-2) Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050421 Firefox/1.0.3 (Debian package 1.0.3-2) When creating new tabs, memory is allocated. It grows as you navigate, but when closing tabs, memory consumption does not decreases. It looks like some "free" are missing! Let Firefox running an entire day, and you'll have you memory filled with garbage! Reproducible: Always Steps to Reproduce: 1. open say 8 tabs and open some pages in them 2. check memory consumption 3. close some tabs 4. check memory consumption again, it did not grow Actual Results: Memory consumption grows and grows... Expected Results: ...after closing tabs, the memory occupied by that tab should be freed!

i have experienced this bug also, sometimes have my Firefox [Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7] running for a couple of days at a time and several tabs open (could be more than 50 open/close over a weekend). when i eventually close the app it might take upto (or more!) 30 mins for firefox to close down whilst consuming nearly 100% processing power and over 100MB memory. I generally follow steps as previously reported and observe similar results.
