Customizing Internet Explorer
Add-ons add different functionality to Internet Explorer. For example, add-ons can add new search engines to the address bar, block ads, and keep you updated on current events.
It's important to note that add-ons are not necessarily created or approved by Microsoft. Many are created by third-party providers or even individual users, so they may not always be safe to install. We recommend reading user reviews carefully before installing an add-on.
Accelerators and web slices are types of add-ons that are available for Internet Explorer. Accelerators allow you to translate, search for, or map text you've selected in the browser. Web slices give you real-time updates for specific websites in your Favorites bar. For example, you could use a web slice to get quick updates on sports scores or the weather forecast.
In our experience, web slices don't work consistently and aren't available for many websites, so their usefulness may be limited.
If you don't like an add-on, the Manage Add-ons feature allows you to disable or remove it from Internet Explorer.
