Feature for multi threading

[varuneranki]

I'm interested in this feature as most websites have ad pop-ups as a result not not so easy to inspect the page i wanted. There's a specific newer ad pop-ups that load underside existing page as well as over the page (this can be seen in a desktop browser) but when it comes to Android existing page is discarded and log continues in the underside ad page. So whenever it happens another instance has to be created. This will lead to issues if there are continuing ad pop-ups. To scale down the threading we can specify the limit of threads.
