Firefox startup error

Hello, I'm trying to install Firefox (had it installed and running before). The installer works fine, both the downloader and the full installer, but when Firefox starts, all that I get is that empty dialog shown in the image. Tried uninstalling, restarting, deleting AppData folders, registry entries, etc. But no luck. Any suggestions? Thanks!

PS: Running Win 10 64-bit fully updated
