Hi Flash, Just some info to correct yours. First, not everyone is having a problem with FP 10.1 and there are solutions and reverting to FP 10.0 would not be the first choice. If that was for you, that's fine. If you would read the many many threads here, you would find correct information for users that want to revert back to FP10.
Also may I suggest you read up on Firefox version 3.6.6 as this is involved sometimes with FP 10.1.
Lastly, I think it is always better to find out what a user's issues are before offering a solution. Reverting back to FP 10.0 is not for everyone that is having a problem nor should it be.
If your instructions solved whatever problem you were having, that's great. However, to recommend this to other users that come here for help without knowing what their problems are may not be the best advice, in my opinion.
There are many other details in the Uninstall Instructions and also the Install Instructions that need to be followed.
That is why it is better for each user to have their own thread and receive help for their individual issues. This is also based on their computer system configuration.
Believe me, if there was one fix for all FP 10.1 or any other version issues, it would be posted
