When trying to send a link, firefox will start opening new blank tabs and continue until I shutdown my computer.
This started about a month ago. When try to send a link from a page Firefox will start opening untitled tabs this continues even though I try to close Firefox. It just keeps going until I'm forced to shut down my computer. Just today the same thing happened just clicking a link within Firefox. It seems to have become very unstable.

See Firefox repeatedly opens empty tabs or windows after you click on a link
You can have infinite tabs opening if you have selected Firefox as the application to handle a file if you get an Open with download window.
Firefox should not be selected as the application to handle a file and you have to remove the action that is associated with that file type.

Set that action in Tools > Options > Applications to 'Always Ask' or delete the file mimeTypes.rdf in the Profile Folder to reset all actions.
