Not that I know of, but it is quite feasible that your http request is failing to cleanup after itself somewhere along the line. > - Is there memory leak known when correclty using Prototype's Event mecanism ? Between page loads? Maybe. Within a page? Certainly. stopObservers currently does not remove the array containing [element,name,observer,useCapture] that was created during the observe call. I have no doubt your code calls Event.observe *many* times in just one page load (use Firebug's profiler to see), and this cache is just growing larger and larger. Even on unloadCache it just sets the element to null. As far as I can tell the function is still stored in the Event.observers array. Also, you may think you are stopping your observers correctly but I have seen many people do the following: Event.observe(element,'click',this.someFunction.bind(this)); Event.stopObserving(element,'click',this.someFunction.bind(this)); which does not work. Of course if you are getting rid of your element at the same time you'll never know because an error is never thrown. bind and bindAsEventListener return new functions with each call, so the arguments to observe and stopObserving above are not the same. And then there are all of the widgets we all love to use (like TinyMCE and SAU) but if they don't provide a cleanup method (usually "dispose") and you don't make use of it you can be sure you are leaking memory there as well. As Martin recently discovered there are plenty of other ways to leak memory, as subtle as overwriting variables (I guess inadvertently creating closures?). In my experience FF will consume as much memory as IE, maybe it's due to the plethora of extensions installed. The easiest solution is yet another extension, the "Restart Firefox" extension!
