What exactly is A SAFARI EXTE NSI ON?
You may have heard about extensions for Safari before without really knowing what they do or how they work. To put it simply, an extension is a small piece of code that enables Safari (or your web browser of choice) to do extra tasks that it ordinarily would not be able to do.
For example, you might install one that enables you to save pages to read later (with extra features beyond Safari’s Reading List) — something that can be particularly useful if you expect to struggle to get online later.
Extensions aren’t just limited to Safari, or just to your Mac. Other web browsers such as Chrome and Firefox have extensive extension (or add-on) libraries on offer, so if you prefer those browsers then you’re not missing out.
You can also install extensions for Safari via the App Store on your iPhone or iPad — just search for the extension you want and download it to get started. Some iOS extensions are enabled from the Share sheet. Open that sheet, tap More at the right end of a row, then turn on the extension in the list provided. Other iOS extensions may require a different setup process — make sure you read the instructions on the App Store or the extension’s website so you’re in the know.
Are they safe?
You might be wondering whether it’s a good idea to install third-party code onto your Mac, especially when that’s combined with going online. In almost all cases, though, extensions are safe.
When looking for extensions, it’s a good idea to take the same approach you may well take with Mac apps and stick to the official source. It’s called the Safari Extensions Gallery, and every extension there is signed and hosted by Apple, so you know what you think you’re installing is what you’re getting. Those extensions are updated automatically, so you’ll get the latest fixes without having to lift a finger.
You can download extensions directly from third-party developers on their own websites, but it’s worth noting that these come without the security guarantee that you get with those hosted on Apple’s website. As such, you should ensure that you trust the developer before you download and install an extension this way.
