Please tell me how to find out the memory leak in browser and what is the best way to solve the problem. Is there any guideline for writing javascript to avoid memory leak?
And also if you can tell me some problem which you experienced related to memory leak and how did you debug and find out the solution would provide a great understanding to me.
Thanks
Look at this IBM article on Memory leak patterns in JavaScript
For Internet Explorer you can try sIEve or the JavaScript Memory Leak Detector from Microsoft (The link to the documentation seems to be broken). In Firefox there is the Leak Monitor Add-on. There is also a list of tools for Firefox here.
UPDATE:
There is a new version of the Microsoft memory leak detector at the link below.

I am trying to debug memory leaks in my application and while searching I came accross memory devtool option.
While ramping over it i am getting confused regarding use cases of "Heap snapshot" and "allocation profiller" inside memory devtool.
Documentation is also making term confusing
Can anyone explain them or share link explaining in much simpler form
Is there any good tool that helps with troubleshooting and debugging memory leaks in Internet Explorer?
Take a look at IE-Sieve
Chrome inspector have capabilities to take memory snapshots under profiles tab.
DynaTrace may help.
Hey -- not sure about analyzing tools, but I know with my mac I can take a snapshot of a process and view it's trace of virtual addresses.
I don't know how much use this would be to you, but perhaps some?
Are there any add-ons for Firefox that I can use to find out with part of the JavaScript causes memory leaks?
I've got nothing for firefox, but the webkit inspector in Chrome has a profiler built in that is great for that kind of thing.
As an added bonus it also shows you all browser events such as repaints, so you can engineer your code to have the least impact on the browser.
Use Drip.exe / IEleak, I used it a lot to search for memory leaks!
Other hits:
jQuery itself prevents a lot of memory leaks!
Test your code with http://jslint.com
There is a tool by Microsoft itself, but I don't know it is up to date: http://blogs.msdn.com/b/askie/archive/2008/12/31/javascript-memory-leak-detector-for-internet-explorer.aspx
There is also integration with Visual Studio: http://berniesumption.com/software/how-to-debug-javascript-in-internet-explorer/
There is a good article about mem leaks http://www.ibm.com/developerworks/web/library/wa-memleak/

The best memory profiler I've found is for IE (supports even IE6 ;-). Give it a go - you will be surprised how good it is:

Memory Leak Patterns in Javascript
http://www.ibm.com/developerworks/web/library/wa-memleak/
Plugging memory leaks in JavaScript is easy enough when you know what
causes them. In this article authors Kiran Sundar and Abhijeet
Bhattacharya walk you through the basics of circular references in
JavaScript and explain why they can cause problems in certain
browsers, especially when combined with closures. After seeing some of
the common memory leak patterns you should watch out for, you'll learn
a variety of easy ways to work around them.
Google Chrome has the ability to take heap snapshots and compare them, which can be used to detect memory leaks and analyse memory consumption in general. There is an article about heap profiling at Google Developers that explains everything.
Debug.js does global leak detection and type checking.
I am looking for an IE 6 / 7 plug-in or something like Firebug_Lite thing that can show the memory usage in runtime, as well as the allocation of memory of each object or variable. Anyone know what tool has this functionality? Thanks.
You could try Drip for memory leaks but in my experience that's pretty much it for IE. Let's wait for better responses :)
Well. i found out there is a tool called Javascript Memory Validator. BUt it is expensive and seems like only work for Firefox. And it is hard to use.
Still looking for a good IE tool for checking the javascript performance & memory allocation.
