Is there any way to force the Javascript Garbage Collector in webkit based browsers?

In internet explorer we can force the Javascript garbage collection to execute with this method: CollectGarbage();

That method is undefined on Firefox. Do you know if there is some kind of equivalent?

Thanks.

(Not just limiting this answer to WebKit-based browsers...)

--js-flags="--expose-gc"

window.gc()

about:memory

window.opera.collect()

window.CollectGarbage()

Note that you shouldn't be manually running the GC. I've only posted this because it's useful for development testing.

I've been just trying to force GC and it seems that regardless of the actual browser relatively good way of doing so is to run following piece of code:

function gc(max)
var arr = ;
for (var i = 0; i < max; i++)
arr.push(i);

return arr.length;

for (var i = 0; ; i++)
// repeat until you have enough:
gc(Math.pow(2, i));



Of course, one issue is to know when to stop calling gc(...): for that one needs some external way to detect the GC is successfully over. In my case I was using embedded WebView and I could really check before forcing next round with bigger array.

I'm not sure if this is not off topic but there is add-on for firefox called FreeMemory (https://addons.mozilla.org/en-US/firefox/addon/freememory/) to run garbage or cycle collection without visiting about:memory pane, with configurable timer. I believe there are alternatives for other browsers out there.

Visit about:memory.

about:memory

From page's documentation on MDN:

about:memory is a special page within Firefox that lets you view, save,
load, and diff detailed measurements of Firefox's memory usage. It also
lets you do other memory-related operations like trigger GC and CC
