Thanks for more replies. to sum up.....my post about m.mask security is partly because ive had trouble linking it to my ledger for extra security [ did a seperate post on this ] . My computer is clean ,as i dont open links/ connect to dodgy sites etc . Also my keys are offline .   I close meta mask when not using it . So , are people saying that i should UNCONNECT from  connected sites to m.mask , then re connect when i need to use them ?
