Here is a quick tip to decrease Firefox memory consumption on Windows, when Firefox is 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 box that pops up enter config.trim_on_minimize. Press Enter.
4. Now select True and then press Enter.
5. Restart Firefox.
When I first tried it, I had 12 open tabs, using about 62 Megabytes of memory, and it did not change when minimized. After applying the above instructions, the ~61 Megabytes of memory shrunk to ~11 Megabytes when minimized. These numbers were all obtained through the Task Manager, and the same tabs were all used thanks to SessionSaver. If you want to conduct this test using my described method, make sure that you have SessionSaver installed first, and also note that the installation of SessionSaver requires Firefox to be restarted. Have fun…
