Hi all, I'm having an odd problem. For some time now, whenever I look at a list of programs on my computer, Firefox shows up twice. In the last week or so, a new problem has cropped up. When I click on a link in Thunderbird, Firefox opens, but it's like I'm in a totally new instance of Firefox. My browsing history doesn't exist, it will not remember that I have already told Firefox to always open Zoom when I click on a Zoom link, and if I'm streaming a radio station, that tab will be in a separate window rather than in a new tab as it was before. What's going on here?
