From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.4) Gecko/20011019 Netscape6/6.2 BuildID: When quick-launch is enabled, the memory usage of the minimized browser is lower than when the browser is closed. - tried with NS6.2 and Mozilla 0.9.7 - tried on Win2K Reproducible: Always Steps to Reproduce: 0. Enable quick-launch! 1. Start Moz., and then use TaskManager to note memory usage. 2. Minimize Moz. and note memory usage. 3. Restore Moz., then close it and note memory usage. Actual Results: Value from 2. is lesser than 3. Expected Results: 3. should be lesser than 2. My guess is that some memory clean-up happens when moz. is minimized (I would guess some form of a garbage-collector). This memory clean-up does not happen when moz. is closed.
