I got an issue in the new version of Fennec(firefox) caused by the installation/removal of another banned web browser (for legal reasons let's not talk about the name of that other browser)...

Basically my system seems to have some components registered to this other web browser that i removed and i need to restore all the microB settings back to the default.

The other browser was un-installed in the normal faction.

The main problem surrounds the JS component.

I have tried the following:
- i have used dbus-switchboard utility to remove the JS file association but made no difference
- i have used browser switchboard utility and changed default browsers around and then back to MicroB, made some minor difference in the way that I'm now able to get into fennec, before it just locked up but still unable to use fennec due to file association being registered to this other un-wanted and banned browser


So resuming, how can I reset the microB default components?

I don't fancy re-flashing the phone!

Thank you
