裡面只有兩項以前沒見過,因此只修改這兩項設定
1.Fetch only what you click
2.Limit RAM usageFx .6 and up: Firefox has this wacky little feature that downloads pages from links it thinks you may click on pages you view, like the top result on a page of Google results. This means you use up bandwidth and CPU cycles and store history for web pages you may not have ever viewed. Creepy, eh? To stop that madness, set the network.prefetch-next key to false.
- Key: network.prefetch-next
- Modified Value: false
All versions: Goodness knows I've done a good amount of belly-aching about Firefox's voracious appetite for RAM. (It's consistently the most memory-intensive process on both my PC and Mac.) Happily a simple config tweak got Mem Use right back down to a more comfortable number. Along with the previous prefetch mod, set your
browser.cache.disk.capacitybrowser.cache.memory.capacity to a value that fits your total RAM.
- Key: browser.cache.memory.capacity
- Modified Value: Depends on your system's total memory. According to Computerworld:
For RAM sizes between 512BM and 1GB, start with 15000. For RAM sizes between 128MB and 512M, try 5000.
