I just got the same problem. I tried the following and was able to restart Firefox.

In C:\Program Files\Mozilla Firefox, you will find two instances of js3250.dll (the other one is named js3250.dll.moz-backup or something like that) . Rename js3250.dll to whatever you want, then rename the backup file one to js3250.dll.

Restart Firefox...

Edited in Message from the Mozilla Support Administrator

PLEASE do NOT do this. You should delete the C:\Program Files\Mozilla Firefox folder and reinstall Firefox from http://www.getfirefox.com. This solution doesn't give you all the security fixes of 3.5.4 and puts you at significant risk.

Read this article for the correct fix:

I had the same thing happen to me...

Anybody know why this happened?

It did not work right away after replacing the .dll file
I made a copy of the backup and renamed it with the date before simply replacing the file name...

firefox 3.5.4 downloaded after restarting the computer 4 times...

It only happened on my XP computer...
Hate to say it, but thank god I had Vista on the other

So.. problem can be fixed...

Why did it happen in the first place? Do programmers no longer test updates before releasing them?

Why is it that firefox used to be the best browser out there with little no problems.

Now they are releasing updates that crash the program.

Not to mention the fact I can no longer have more than 2 tabs open due to its memory usage.
Now, I have 4GB ram, it make NO difference to firefox, after the 3rd or 4th tab, I can barely move around firefox.

My speech is simple: Mozilla need to go back and do some re-thinking about their browser. Or they are going to continue along this downward spiral and i will have to make a permanent switch to Google Chrome.

@Drake

I'd say you have something else causing you problems. I have a an old computer that I built back in 2002 running XP and only 1GB of RAM with an Athlon XP 1800+ processor. It's pretty old by computer standards and at any given time I usually have between 10 and 15 tabs open at once and Firefox will be using between 150MB and 200MB.

If you've got 4GB of RAM and FF is running slow with only 3 or 4 tabs I'd say you got something else contributing to the problem.

On a side note: renaming the file fixed the problem for me too.
