Error appeared while working on Mozilla Firefox

Asked By 20 points N/A Posted on -


Just the other day, one of my users was working on Mozilla Firefox. Everything was running smoothly, but all of a sudden, the following error appeared on my screen:

Mozilla Firefox error-Ih2hS19bXnpycHhe2Pq4


An error occurred

The error was reported with the following id: 'Ih2hS19bXnpycHhe2Pq4'

Please send this error message to us:

'Errorld: In2hS19bXnpycHhe2Pq4 UserAgent: Mozilla/5.0 (Windows NT 6.1; rv:9.0.1) Gecko/20100101 Firefox/9.0.1 io is not defined in at line 9'

This is a very strange kind of an error I have ever seen. Anybody has any idea as to what went wrong in my system? Your helpful suggestions are needed please. I have searched a lot about this error, but I couldn’t find anything useful.

Looking forward to your replies.

As you have said in your post, I think it’s a registry problem due to long term windows use. There are many ways to solve this problem by editing the registry of your windows.
This may take long and you may not able to fix this error properly with all of your expectations. So, I think you should use the windows registry fixing tools to overcome from this problem. Here you need to just download a simple registry resolver like:
1. Tune Up utilities.
2. Advance System care.
This software is available in the internet. Just download and install it. Check your system registry and fix it.

Hi Rodriguezscotte,

You said that it is strange error, yes, you are right. This error occurs when some exe file removed from the installation software. I think you should download Firefox new version from this link:

Thank you.
