In my Windows 10 PC, I had 1 browser window, with all financial accounts bookmarked on the Fire Bookmarks Toolbar. This window had the extra security tab on the side that I believe added an extra layer of security around activities on those sites. Windows (11) forced me to purchase a new computer... Now I'm not sure how to set that up in this latest Firefox and Windows 11. If I select that secure level described here that warns it could cause breaks in activities on some sites, is that the same protection? Will it serve that purpose and can I again only have that level of protection on that one browser window, saving it apart from the main Firefox icon? Please know any answer will need some plain English - I'm not up to date on computer terminology after 18 years away from my days of understanding. (Windows 3.11 - 7 experience) Thank you for reading this. Hope someone can point me in the right direction!
