Getting rid an add-ons and pluging in browsers

If you have browser extensions you're not using, they can slow down your Mac and sluggish web browsing. Moreover, you can have extensions and plugins you never installed. They just appeared in your browser at some point and you would be lucky if they’re not malware or bloatware. How did it happen? When you browse the web and download stuff from unknown websites, some of them get paid to add extensions to their download items. That’s how you end up with weird add-ons, search bars, ad stripes, trackers, and other useless additions. If you need to quickly disable or remove all the sluggish extensions from all browsers, use CleanMyMac 3. It’s a safe Mac cleaner that lets you remove all add-ons a few clicks.

The difference between add ons, extensions and plugins

Add-ons, extensions, and plugins - what is the difference

While often used interchangeably, these terms are quite different. Let’s make clear what they are first. All of them are pieces of software created to extend the functionality of your browsers. All of them are installed onto a browser and run with it, providing you with additional tools. And all of them don’t come as part of the browser initially because they’re not essential. Now, let’s assess the differences.

Plug-ins or plugins can only change something in the web pages you’re seeing. They cannot install toolbars or provide additional menus in the browser itself.

Extensions are the same as add-ons and they can do all sorts of things, like add stuff into the browser, process and change web pages, etc.

To make it even clearer: an extension can have a plugin inside of it, but not vice versa.

For the most part, extensions (or addons) do a good job of enhancing your browsers or apps in the way you need them to. However, when there’s a too much of them, they are poorly mare or even malicious, you can have troubles.

Quickly remove add-ons and adware from browser

How to quickly remove add-ons and adware from browser

If you tried to remove extensions manually but your Mac still have troubles working or loading web pages, we suggest using a Mac utility like CleanMyMac. This is the one app you really need if you want to save time. Just upload it and you are ready to go!

CleanMyMac 3's Extensions allows to remove not only plugins and add-ons that we’ve talked about, but also Widgets, Application Plugins, Preference Panes, Dictionaries, Screen Savers, and Login Items easily.

Apart from ordinary applications, there are quite a lot of other software components on your system, that can be generally described as extensions. This module of CleanMyMac automatically sorts these items into the corresponding groups for you to work with:

  • Widgets

Your small Dashboard apps can be easily disabled or completely removed along with all related data.

  • Login Items

Manage the list of applications that will be automatically launched every time you log in. Sometimes small adware programs also sneak into your startup items without your approval. Preference Panes All of your Preference Panes come with tons of support files spread over the system, which are hard to locate without CleanMyMac.

  • Screen Savers

Removing an unnecessary screen saver correctly is easy with CleanMyMac. However, you can also disable one to make it temporarily unavailable for System Preferences.

  • Dictionaries

Not all the inbuilt Mac OS dictionaries are of any use for you, but they do waste space. You can easily remove unnecessary dictionaries or disable them temporarily.

Check and edit extensions with CleanMyMac

After you have reviewed the lists, you can click the ‘Disable’ button next to virtually any item to isolate it from your system:

Or, you can select items for complete removal using their corresponding checkboxes.

Remember that disabling an extension is an easily-reversible operation, however, if you decide on removing an item completely, you will not be able to undo this action.

If needed, any of the listed items can be added to CleanMyMac’s Ignore List so that it never offers to remove them later.

After you have looked through the sections you found interesting and selected the unwanted items, you can go ahead and use the main Remove button to finalize your work.

Now you know everything there is to know about extensions on Mac and how to deal with them. We hope this guide has been of help.
