本文介绍了Firefox浏览器内存分配的设置方法。先打开新标签，在地址栏输入“about:config”并回车；右键选“New”再选“Integer”，输入“browser.cache.memory.capacity”；根据电脑内存情况在对话框设置分配值，如16MB输入16384；最后关闭对话框，重启Firefox，若无效可尝试重启系统。

I noticed a few Firefox threads here have people complaining about how much memory Firefox takes up. This is a known memory leak, and the Mozilla guys haven't gotten around to fixing it for whatever reason. But there's no reason your Firefox should take up 70,000K in memory, so here's how to fix that memory leak and keep Firefox from bloating up.

1. Open a new tab. Type "about:config" without quotes into the address bar and hit enter/click Go.

2. Right-click anywhere, select New, then Integer. In the dialog prompt that appears, type:

browser.cache.memory.capacity

3. Click OK. Another dialog prompt will appear. This is where you decide how much memory to allocate to Firefox. This depends on how much RAM your computer has, but generally you don't want to allocate too little (under 8MB), but if you allocate too much, you might as well not do this. A good recommended setting is 16MB. If you want 16MB, enter this value into the dialog prompt:

16384

(Why 16384 instead of 16000? Because computers use base-12 counting. Thus 16 megabytes = 16384 bytes. Likewise, if you want to double that and allocate 32MB, you'd enter 32768.)

4. Click OK to close the dialog box, then close all instances of Firefox and restart. If your Firefox still uses the same amount of memory, give it a few minutes and it should slowly clear up. If that fails, try a system reboot.

Hope I did a service to some FReepers today.
