Hello! I can't figure out what setting to fix this: every time I click to open a new window, about 35 tabs automatically open up that I have closed several times in the past. I simply want one new window without any previously opened tabs. I've tried: * clearing my entire search history several times * shutting down Firefox and reopening (which opens up all those tabs) * uninstalling Firefox and reinstalling it * initiating the latest Firefox updates * restarting my computer * turning my computer on and off * looking through every single preference in my Firefox settings (I've unchecked anywhere it talks about opening tabs) * reading various articles on Firefox's support page and on other support websites to try to figure this out (there's little info on this problem; the support is mostly about how to save previously opened tabs Please help! I'm tired of having to close down all these tabs every single time I have to restart my computer or have to shut down Firefox. It slows down everything I'm trying to do. Thank you!
