It would seem on computer reboot that Norton deletes the extensions.rdf file in Firefox !!

This is interesting, because on firefox startup, Firefox recreates the rdf file from what is installed in Firefox, (if the extensions.rdf has been deleted)

So Norton is installing norton files and then deleting old rdf (or is the other way round), so that firefox, when it opens, makes a new rdf which includes the norton extensions..

I have been looking at the rdf file
not so easy to edit as I thought.

So maybe knowing the above, load (and maybe remove) the extensions you want (don't want) in firefox.

close firefox

delete extensions.rdf file

restart firefox

make extensios.rdf read only.

(do NOT restart the computer when doing these things)

(doing this saves editing the rdf)
(If Norton can do it, so can you !)

This should keep Norton's from deleting the rdf file again.

However I would not do all these things this without a Full Proflle backup in FEBE for safety.....

Nope it aint me,..

I changed the rdf file to read only but on re-boot fast dial was incompatable, so changed it back again and, you guessed it, reinstaled fast dial!!

.....ooh my brain hurts!

but it would seem I am not alone.

Not saying it will work.

Saw this in relation to another question

But maybe give it a try

Install Fast Dial
But do not restart firefox to complete the install.

Close computer

reboot...

Is fast dial there ??

Ah very interesting..

That was lucky !

Thanks for the feedback..

Please keep me posted either way...

Big shame....

Keep a watch on that Norton site..
