Hi, Currently, my Firefox 133.0's default behavior is to open bookmarks in the currently active tab when clicking on them. This is fine for some applications/websites but impractical for others. With webmail clients, IP surveillance cameras, or weather forecast sites this can become a real pain, especially if someone keeps multiple instances (windows) of Firefox open across multiple virtual desktops (as I do). I end up opening these sites over and over again in different tabs. I'd like specific bookmarks to be opened in a new tab/window if and only if that site is not already open; otherwise, bring that particular tab/window up instead of creating a new one. How could this be achieved? Thank you very much!
