WFM with a clean profile on FF 23.0.1 (Build ID: 20130814063812) and latest Nightly (Build ID: 20130819030205) with the URLs from comment 0.

Naveen, could you please test in safe mode: and with a new profile ?

Same issue?

Yes the same result. There is lag/freeze and micro freezes when loading multiple google forum link.

Here is the profiler screenshot

here is for dota 2 store
Works for me too from MacOSX. Naveen, are you still seeing with the Firefox 24 release?  I'm tagging this bug with "hang", but I'm not sure how to proceed any further without being able to confirm the bug.

I am currently on FF23 stable and no plans in moving to other channels.

I am not the only here i guess 

Anyway to post any logs during this hang ?

Naveen, now I am seeing it in Firefox 24. I hadn't realized I needed to load all the tabs at once. When I did that the issue was easy to see.  At first, switching tabs doesn't work while the Forum tabs seem to be loading or re-loading their content. After a minute or two, the "stutter" stops happening. 

I can't replicate the problem in Nightly (26.0a1)

thanks . I did mention it in my FP to open all these at once. If you try opening dota 2 also while trying to open google forum , the browser almost comes to an halt. Sorry for comparing , but this doesnt seem to happen on chrome. anyway good to know its reproducible.

Liz, I also can't reproduce today's nightly 64bit build on win7
(not a clean profile)

I suggest this is WFM

Naveen, you don't need to "install" firefox to test it (and thus mess up your current install).  You can download and unzip and run it from the unzipped directory

same issue. 

Opening dota 2 store alone was very responsive. But when i try to open google forum , the problem occurs again.

Also is there a way to run your FF 26 without add-ons ? it seems to take all the add-ons , config of the current installation. I unzipped and ran from desktop .

Started a fresh profile and opened multiple links (dota store , google forum) with nightly and still it has the issue.

The browser starts to hang when you open multiple tabs (4-5 google forum links) + dota store site and try moving through tabs quickly. It will hang and come to an halt.

Hope its reproducible for you too.
It was reproducible in FF23 and 24. I will look for a regression window to see if we can usefully narrow down where the issue was fixed between the 24 and 26 versions.

That's a lot of work, and only needed if your are desperate to find what fixed it.
At minimum, based on liz's testing it is likely that it will work for Naveen if a current version is used (you could test it yourself by downloading a zip)
