Thx a lot. I used Firefox 24 and the BFCache or normal cache is easy to figure out.
But this system is built on that old version of Firefox and depend on some constraints(just like IE6 in China).I can't update that system. However,if those grey request is from cache,the 160+ms grey column is also the time spent in execute js/css/dom, not just the gap? 在 2013年10月17日星期四UTC+8下午7时51分50秒，Sebastian Zartner写道： > > Hello.I'm using Firefox 4.0.1 and using firebug 1.7.3 to monitor >> js/css/img/etc download from my server. >> > This configuration is completely outdated.
