Switch to Firefox
Mozilla Firefox is available for almost every platform you can think of: Windows, Mac, Linux, Android and iOS. You can download the browser from Mozilla's website and then follow the instructions to install it.
When you start Firefox for the first time, it will ask you if you want to import data from another browser. This will allow you to download favourites and bookmarks from almost any other browser. From Chrome and Internet Explorer, you can also bring cookies, history, and saved passwords.
Switching to Chrome
Google Chrome is available for the same platforms as Firefox: Windows, Mac, Linux, Android (where it is often the default browser) and iOS. You can download the browser from Google's website and then follow the instructions to install it.
When you first start Chrome, you'll be asked if you want to transfer data from another browser. From Firefox, you can take favourites, history, saved passwords, search engine preferences and form data. Internet Explorer allows you to transfer favourites, history and saved passwords, and Edge and Safari only allow you to transfer favourites.
Switching to Edge
Switching to Microsoft Edge is easiest if you already use Internet Explorer, Microsoft's previous and now obsolete browser. You can take almost all data with you. You do this by clicking on the menu button at the top right and then on 'Settings'. Then select "import and export". Now you can select which browser you want to import data from.
Note: For Chrome, you can take along favourites, history, cookies, passwords and settings. Firefox only has favourites.
