Hi, why is firefox opening multiple duplicate tabs when I open new tabs?

It is currently saying I have over 3,000 tabs open?! I know I do not have even nearly that many tabs open.

Consequently this is slowing down my online usage

Many thanks :)

Hi. One of your settings is probably causing the problem. Have you chosen Firefox to open certain files?

Hi Terry, thank you. I'm looking at the info you linked me to. Firefox is only chosen to open images.

I can't actually see the duplicate tabs, but I know they must be duplicating somehow because there is no way I have over 3,000 tabs open. I do often have multiple tabs open, but nowhere near even one thousand.
