Is Internet Explorer disabling my Mozilla Firefox?

[OhioGuy]

Earlier this week, I couldn't get a car rental page to load properly. I
remembered that occasionally, I'll run into something that will work in IE,
but not Firefox, evidently due to poor website implementation or design.
So, I tried loading the page in IE. Still wouldn't work.

However, after doing this, Firefox would no longer run. Instead, I got
the message:

"This application has failed to start because js3250.dll was not found.
Re-installing this application may fix this problem."

I have since had the same thing come up 3 times, including again this
morning. It appears that by running Internet Explorer, I am always causing
some sort of problem that forces me to uninstall, then reinstall Mozilla
Firefox before it will work again. It is always this same dll message.

Anyone know why in the world running IE would do something like this? Are
other folks running into this? Is Microsoft somehow purposefully trying to
disable firefox?

Thanks!

Try making the js3250.dll read-only.

Then make a copy of it and store it somewhere else. Copy it to your Firefox
folder when it happens again. If you put it in your \Windows\System32 folder,
it may solve the problem altogether.

Dunno what's killing it... Does the file actually go missing, or is it a Path
problem?
