We knew that Firefox has problem with the memory usage. Sometimes it can reach to hundreds of megabytes. But here is a tricks on how to reduce the memory usage when you minimize your Firefox.
- Type about:config in Firefox address bar and press Enter.
- Right click in the page and select New > Boolean.
- Type config.trim_on_minimize in the box that pops up. Press Enter.
- Select True and then press Enter.
- Restart Firefox.
What it will do is, when each time you minimize your Firefox, the memory usage will dramatically drop down to 10Mb (this is what happen on my PC) but then it will slowly increase up to 50Mb. When you maximize it back, it will stay on 50Mb or maybe 70Mb.
Note: This is only to reduce the Firefox memory usage when you minimize it. Not to fix them. 🙂
