Seems to be nothing of interest to me there (some is Firefox programmer stuff).
Now when a firefox add-on allows two or three or four "Find" fields (we had a thread on that) -- then I will be go right to town.
Good news. I will try the new release of Find All. Individualizes the Find for each tab, which is similar functionality. I may also look at Find Toolbar Tweaks and some others, however it looks like you generally have to decide on one Find extension for compatibility.
Oops .. check that. Find All does not seem to have that functionality, I think I read about it for one of these find search extensions.
