Two clicks change that, and those two clicks remove most of the ways a page can attack a browser.
The shield icon next to the address bar. Open it, choose settings, pick a level. That is the whole operation and it survives restarts.
| Level | Scripts | Suits |
|---|---|---|
| Standard | Everything runs | General browsing where nothing much is at stake |
| Safer | Scripts off on plain connections, some media blocked | A compromise, and the least useful of the three |
| Safest | Scripts off everywhere, most media blocked | Anything you actually care about, including this |
Nearly every serious browser problem in the last decade came through scripting. Turning it off removes that surface entirely rather than reducing it. A marketplace worth being careful about is exactly the case where you accept a plainer page in exchange for that.
When a page misbehaves the instinct is to lower the level until it works. That trades the protection for a cosmetic improvement, permanently, because people rarely put it back. If a page will not work on Safest, decide deliberately whether that page is worth it rather than changing the setting out of habit.
Nearly every phishing story starts with somebody looking for an address during an outage. Saving them properly is the cheapest defence there is.
