Permission review
Read/change all data on all websites means the extension sits next to webmail, banks, work portals and password forms. Treat that permission like a little account-access grant, not like a harmless toolbar preference.
Devices
Phones, browsers, laptops and extensions are where people actually type secrets. Boring, patched and official beats exciting and infected.
Nigel version
Update quickly, remove mystery extensions, avoid cracked tools, and keep experiments away from work/tax/banking devices.


Device shelf
The browser, phone and laptop are where real sessions live. The goal is not to ban curiosity. It is to stop coupon add-ons, fake installers and weekend experiments sharing a shelf with banking, tax, passwords and work.
One add-on that can read every site sits beside webmail, banks, work portals and password forms.
The serious browser or laptop still has avoidable clutter beside valuable sessions.
Explain the jargon
Tap a term for the plain-English version and the practical move. No fake mystique, just the bit that changes what you do at home.
A browser-extension permission that can put the extension beside webmail, banking, work portals and password forms.
Do this: Keep only extensions you trust and use. Remove broad-permission add-ons from serious browser profiles.
A download that pretends to be a real app, update, codec, mod or driver but runs something else as well.
Do this: Use the official store or vendor site. Be especially suspicious of search ads and download mirrors.
Pirated software, keygens, cheats and mod loaders often ask for the exact thing malware wants: trust, admin rights and a user willing to ignore warnings.
Do this: Keep them off serious devices. If you must experiment, use a disposable profile, VM or spare machine with no saved sessions.
A browser or OS user profile reserved for banking, tax, work and password-manager use. No experiments, cheats, coupon tools or mystery add-ons.
Do this: Create a separate tinkering profile or VM so curiosity does not share a room with your most valuable sessions.
Full guidance
A practical device shelf for deciding what belongs on sensitive computers.
Read/change all data on all websites means the extension sits next to webmail, banks, work portals and password forms. Treat that permission like a little account-access grant, not like a harmless toolbar preference.
Vendor site or official store is not perfect, but it removes a large amount of fake-installer theatre: sponsored-download traps, lookalike update pages, cracked-app bundles and fake driver utilities.
If someone wants mods, experiments, cheat tools, coupon extensions or unsupported apps, keep that away from the machine used for work, tax, banking and passwords.
The boring device rule exists because these stories keep rhyming: a browser add-on gets broad permissions, a fake installer arrives through search or a forum, a cracked tool wants admin rights, then the user's normal sessions become the prize. You do not need to scare a family with every malware name. Just make the serious shelf boring.
Scenario
It saves two dollars and can read every site.
Better response
Worse habit
Keeping it on the banking/work browser because it is convenient.
A driver, meeting app, game mod or PDF tool is downloaded from a lookalike page or sponsored result.
Better response
Worse habit
Clicking through because the app appears to work after the installer finishes.
A keygen or cheat asks for admin rights on the same machine used for banking, tax and work email.
Better response
Worse habit
Treating malware warnings as the price of getting the app free.
