Downloaded the Extension, restarted FF, and all is back to normal! I will have to think about where I go from here, as I know I am up against a lot of limitations between Win 7, the 4meg limit on my computer memory, and FF… Part of the on-going problem is the number of old programs I need to keep using.

I am sorry I have been slow to reply to the most recent posters. My 16.5 year old cat has been very ill for the last week and has been in hospital (he has had another tooth extracted and a nasty lump removed - this surgery on top of last year’s tooth extraction, treatment for over-active thyroid, and his ongoing battle with kidney failure has been very stressful and I haven’t been on the computer much as a consequence. I really want to personally thank everyone who contributed to trying to help me out.
