I feel naked as I've had to uninstall Sandboxie 5.12 on x64 W10 desktop. Sandboxie would not "keep" Firefox v47.0.1. I tried upgrading with Sandboxie enabled and disabled. Every new session would revert to v47, then a warning about T F & S C, even if I disabled it, and then render my Firefox bars and drop down menus with large thin fonts in the bars and drop down menu fonts so small you could hardly read them. Anyone else experiencing this? I'll post this on Firefox and Sandboxie forums too! Thank you!
