I want Firefox to use the same tab for all URLs in a single domain. In other words, if I already have Bugzilla open in one tab, and I click a new Bugzilla link from an email, the new link will open in that existing tab (or in a new tab while closing the old tab).
Is there a way to do this?
I tried the "Close other tabs" add-on for Firefox, which has an option for "Close tabs with this domain". That's almost it, but no, it closes ALL tabs with the current domain. And I don't want to close them all, I want to close the old ones.
Basically, like a desktop application, I want ONE instance of each web application running at all times. It seems like such an obvious desire, especially for those that work on software, that I'm surprised I can't find anybody saying anything about it anywhere.
Is it possible?
