OK, each time I've updated Firefox, it immediately locks up as much memory as it can grab. It apparently is not releasing memory after a website (especially a site like YouTube) has been visited. It is horribly slow to render webpages and most of the time won't connect without many tries (when same website will open in Internet Explorer without problem). Most recent experience is that after visiting two or three websites, closing those and opening only Horde webmail, over 900MB of memory is in use by Firefox.

Fix it or I send it to the scrap heap where it belongs. Free is free but not much worth if it doesn't work. At least be professional if you are going to release this stuff and test it before release!
