Install spell checker in Firefox

Typing and spelling mistakes don't make a good impression on the Internet either. Installing a spell checker in Firefox takes just a few seconds and indicates errors in the familiar Word design. This is especially helpful when it comes to emails. We'll show you how to install such a tool.

How to install a spell checker in Firefox

• The free add-on "German Dictionary" is one of the best spell checkers for Mozilla Firefox.
• Click "Add to Firefox" and start the installation process.
• After restarting your browser, the add-on is active and all errors are underlined in red.

An alternative is the LanguageToolFx add-on, which also detects duplications in the text.
