Solution for Facebook chat cause the browser to lag (Anyone using Firefox 3.5.x)

Anyone using Firefox 3.5.x(yes, it happens in 3.5.7 as well) and experiencing the glitch where incoming messages in Facebook chat cause the browser to lag, I think I've got a solution for you. Enter "about:config" in the address bar, find the entry "javascript.options.jit.content" and change it from true to false by double clicking on it. Restart the browser, and the problem should be fixed. The problem seems to be the native-code compilation that Firefox recently added/enabled for JavaScript, under the name TraceMonkey.

·  1 Type "about:config" into the address bar and hit return.

·  2 Look for “network.http.keep-alive”. If it’s false, double-click that line and to change it to true.

·  3 Make sure “network.http.version” is set to “1.1″.

·  4 Look for “network.http.pipelining”. If it’s false, double-click that line and change it to true.

·  5 Set "network.http.proxy.pipelining" to true by double-clicking it.

·  6 Set "network.http.pipelining.maxrequests" to 8 by double-clicking it. This means it will make 8 requests at once. There is no point setting it higher then 8 as it is capped at 8 max. The default value for this setting is 4.

·  7 Optional: Right-click anywhere and select New-> Integer. Name it "nglayout.initialpaint.delay" and set its value to "0". This value is the amount of time the browser waits before it shows you the information it receives. This is particularly helpful on pages with search bars, however, it doesn't actually make the page load faster.
