5. Strip away the metadata of your photos and documents when sharing them

Is underrated and extremely useful. Good post

Good advices but an easier solution to point 3 is using an e2e encrypted password manager or a offline only one.

9. Silo ALL online accounts. All online accounts should have a separate name, avatar, email alias, etc, and be opened in assigned Firefox containers. Burner email aliases will be your friend here. Do not link these accounts, or if you must, link one or two but have them dead end there. The last thing you want is someone hopscotching all the way to your front door.

In reference to #5, daily use of BleachBit at the end of each computer session. Tick the 'Free Disk Space' box under the System options. Takes about an hour and a half for my system, so I run BleachBit in the evening. It won't free up disk space, nor will it make your computer run faster, but it's certainly good for security aspects. PrivaZer is also a good piece of software but it's windows based.

#3 is a pretty good tip although Bitwarden's track record of breaches that resulted in password leaks, is fairly substantial.

#6 makes me giggle because I do that for rare pictures I post online. Sometimes, I'll inject something like 'The music is reversible but time is not. Turn back, turn back, turn back' in one of the exif slots, just to see if someone is paying attention. BTW, the phrase is from an ELO instrumental that was laced with a backwards message. IIRC, the same song was used by NBC for an intro to one of their sports broadcasts back in the 70s.

firefox makes #1, #4 & #5 easy with tabs & profile manager and #3 sounds clever; thanks for that.
