and this is actually also a good suggestion, since you used that browser to set up different device model.
p.s. heh, that didn't even come to mind cos I use private tab in 99% cases and if I need to use regular tab (iirc, gos installation is only via regular tab(example)) I clear it immediately. same to js, I enable it only if needed)
