Safari IS fast, isn't it?
In order of their frequency of use my Safari extensions are…
- AdBlock Pro (which installs as 8 different blockers that can be individually tuned on or off in Safari > Preferences > Extensions. It is also compliant Safari's ability to switch ad-blocking off or on on a website by website basis.
- WIPR an additional level of ad blocking.
- 1Password that provides an in-app link to the password manager of the same name.
- InstaZoom link to Zoom meetings.
