Watchlist item ends up in cart?

[danasty_stl]

Just what the subject reads. When I add or remove items from my watchlist, they often end up in my cart. I have tried to play around with it to figure out if there is some sort of trigger, but it seems completely random. I think that it may be an issue with Firefox, but wanted to see if anyone else had experienced this before?

I have the same problem, it is very annoying that in the end you have a dozen products in your shopping basket and after that the same number of incomplete purchase emails appear, I have called ebay three times I was told that they could not see anything in their system and that it was probably a virus on my computer, I did a cleaning on my computer and it keeps happening again and again, I think this is a issue that should be solved by the ebay technical team (I think they made that system to boost their sales)
