Have you ever noticed that in the task manager Firefox takes up so much memory. here is a little tip to put it in its place. PROCEED VERY CAREFULLY. 1 open firefox, type about:config and press enter 2 right click on the page and select new option then select Boolean 3 enter the following string config.trim_on_minimize press enter 4 find the value and make sure that it is set to true 5 restart firefox, what this has done is when the user minimizes firefox, it will reduce its memory consumption. Hope this helps -------------------- Regards Alan

In the box that opens, just paste this into it: config.trim_on_minimize Click the OK button. Now, look for the entry you created (config.trim_on_minimize), and make sure it says true, under the Value column. If it says false, just double-click the entry (config.trim_on_minimize), and it will change to true. Close the about:config window.

Guru at being a Newbie Group: HJT Team Posts: 5,715 Joined: 8-April 04 Member No.: 96	I used this tip for a while but have reversed it. Had no ill effects at first, but over time Firefox became unstable. Changing the value back to false fixed that. Your mileage may vary, depending on what extensions you have installed and how many tabs and windows you have open at one time and other factors. From what I've read, it is common for extension writers to fail to test for memory leaks before they post the extension. Altho i think Firefox 2.x still leaks on its own. Remember that this trick will only reduce Ff's memory consumption when you minimize the browser window(s). Whether left minimized or not, as long as the browser is open, memory consumption will steadily increase again until it is minimized again. -------------------- You know everybody is ignorant, only on different subjects.

Member Group: Members Posts: 38 Joined: 28-June 07 Member No.: 140,043	i tried this ... memory usage dropped from 60,000 K to 6,000 K but, i kept my task manager open and monitored Firefox.exe and i noticed it was steadily rising back up. Anyone know why this is? is it a leak from extensions ? I use FF 2.0.0.4 with a whole lot of add-ons like: NoScript ADblock Plus Redirect Remover Dom Inspector Download Statusbar Download Them All Fasterfox IETab Link Alert Yahoo Toolbar Bugmenot --------------------
