I'm currently looking for a job, and I keep my windows separated by category, so I have one that is job search related, and the other that is more general. In my job search window, I have many tabs open for different job postings that I want to hang on to /keep track of. When I want to jump to one of these tabs, I open a new tab and type in whatever its title would be, and then when it pops up in my history I click the "Switch to tab" shortcut to get to it. I find it saves time as opposed to sifting through 50 tabs. In this case, I was trying to find a tab that was opened to a sales job posting, and I clicked switch to tab. However, it took me to a what I think is an entirely separate window, one that I didn't even have open previously, and my jobs window disappeared. I tried to reopen it in History, but it didn't show up. Does anyone know what might have happened here, and how I can recover that window?
