Hi, is it possible to know that, if Firefox or any browser is opened, whats the amount of memory taken up by each TAB of web-browser ?
I am just curious to know.

Firefox, I've made an addon which displays tab memory usage in the corresponding tab's title.
Provides user with tab related stats and memory usage ..
You can use
about:memory. But, it does not look very well organized such as Google Chrome.
Project Electrolysis has been released! Now Firefox is also multi-process.
about:performance. It seems to give real-time data similar to Chrome's Task Manager.
The add-ons don't work in Firefox Quantum, since the add-on framework has been changed now.
about:memory?verbose in the url bar, and check each of window nodes. It should do the trick.
Unfortunately the way that Firefox tabs are implemented, and the way that
about:memory is structured, it is not trivial to determine the memory usage per-tab.
about:memory is really a tool for debugging and development purposes, and since tabs are still part of the same process, you cannot get the same per-tab stats you do in Chrome/Chromium.
You won't get a better answer from your bounty, because there's nothing anyone can do about that at this time.
In the latest nightly from the Mozilla nightly PPA, this is what
about:memory looks like (I've selected the section that shows you the open tabs):
As you can see it is possible to tell by the URL which tab is being referred to, but in reality there is memory being used in other aspects that cannot be illustrated accurately here because it is all one process, but many threads.

I use the other Firefox extension. It is called Tab Memory Usage, https://addons.mozilla.org/en-US/firefox/addon/tab-memory-usage/
