Dear Swarnava,

Please install the file of that link and see the crashing just at the start! As you see it's not working :(

Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":

• https://support.mozilla.org/kb/Basic+Troubleshooting#w_8-make-a-new-profile

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

There are only official 64 bit builds for Linux.
The 64 bit builds for Windows are only compiled to check for compiler problems and aren't supported or guaranteed to work.

• http://nightly.mozilla.org/

So use the 32 bit version for Windows.

Dear cor-el

There was the 64bit builds of Nightly for Windows before the April,1st 2012. But I don't know why there is only 32bit build for Windows now.
