I had read on Barry's blog that he had made another tweak to the Foxfire pet.I have re-uploaded the FF PET, think it should fix the problem:

Finally got around to testing it on my machine this morning. After downloading the new pet from the link posted on his blog, I now have Foxfire(Namoroka 3.6.13) and SM browser and mail client all working together.
Had to move back to Wary 5.0 from Lupu 5.2.0 where I've been quite happily using Firefox and Thunderbird for a couple of weeks now, but figured I had better test the tweak since I was one of the ones 'complaining' about it..
Thanks again for all your work on this issue and Puppy in general.
