Every time you open a new Firefox window a new tab appears pointing to http://interclue.com/1.5.4-update.html
Firstly, we here at Interclue are unable to re-create this problem. We think we know what the problem is but we cannot be sure without a complete copy of a users profile to test.
We know the problem can occur if the Interclue preference set is missing or corrupted. If this is that case then Interclue will think it has just been installed for the first time, and then it will show the first install page.
We believe the problem comes down to the interclue preference set not being saved in the users prefs.js file. We have only received two copies of the prefs file from people suffering this problem. In one copy the Interclue preferences were corrupted. Any attempt to load the preferences resulted in an error and the entire set of preferences had to be discarded. In the other prefs file the entire preference set was missing! No extension preferences had been saved at all. We also noted that many preferences where missing.
The problem now splits into two distinct parts.
If your preference set is being corrupted then installing the latest beta should work
For some unknown reason your preferences are not being saved to the prefs.js file when Firefox closes. There is a simple test you can do to check if this is the case.
Interclue does nothing unusual with your prefs.js file. We urge you to uninstall Interclue and run the test again to make sure this has nothing to do with Interclue.
Try installing the latest beta version of Interclue and restarting your browser, and tell us if this works. If it doesn't work then send us a copy of your prefs.js file. The file is located one of the following places
C:\Documents and Settings\{Windows login or user name}\Application
Data\Mozilla\
C:\Users\{Windows login or user name}\AppData\Roaming\Mozilla\
~/.mozilla/
~/Library/Mozilla/
