Most of you must be aware that setting config.trim_on_minimize’s value to TRUE would minimize RAM usage of Firefox when minimized.
1. Open Firefox and go to the Address Bar. Type in about:config and then press Enter.
2. Right Click in the page and select New -> Boolean.
3. In the dialog box that pops up, enter config.trim_on_minimize and hit Enter.
4. Now set value to True.
5. Restart Firefox.
Now, FF would use very less memory, which is very evident from the Task Manager too.
However, when you restore Firefox again, it takes more time as everything needs to be brought back status quo. This can make your surfing experiences a lot slower, having to wait for FF to regain virility again.
So, it’s better not to enable trim_on_minimize if you have a decent enough system.
