Firefox 2.0+ and JRE 1.6.0

[Tomcat76]

Firefox 2.0.0.1 (and up) spits out an error message every time you start it up if you have Sun's JRE 1.6.0 installed.

The information file for the "Java Console" extension for Firefox (installed when you installed Sun's JRE) lists "2.0" as the maximum version it is compatible with. This excludes "2.0.0.1" and up as being "too new." That's why you get the error message, and the Java Console is disabled if you continue.

Here's a script that ups the maximum version setting to "5.0", allowing you to startup Firefox normally again until it hits version 5.0.0.1.

The script checks your registry for the various Firefox installation paths on your system and updates the Java Console information files it finds in those.

A backup of the original information files is created as well. If you run the script a second time, it will ask if you want to restore the backup.

USE AT YOUR OWN RISK!

Really? Since when?

I have no issues with mine. JRE 1.6.0.1 and FF 2.0.0.3

It may depend on the setup. I've just prepared a system for someone with only FF2 and JRE 1.6.0_1 and the error message did not appear. The Java Console was disabled automatically, though, and, after applying the patch, the Java Console would appear again.

On my own PC, I have the following folders in Program Files:

Mozilla\Firefox 2.0

Mozilla\Firefox 3.0

Mozilla\Seamonkey 1.1

Mozilla\Seamonkey 1.5

It may be that something in this setup is causing the error message to appear.

It's definitely not a "default browser" setting since Opera 9.20 is set to default on my PC.

This is a known issue, though. Check this thread on the MozillaZine forums.
