How to Add SpellCheck to Mozilla

If you’ve ever spent the better part of a half hour filling in a commercial Web site’s required information fields, you know how frustrating a few missed letters or keystrokes can be. When you add spellcheck to Mozilla applications like Firefox or Thunderbird, you can check the spelling of field entries and save yourself a lot of aggravation.

Instructions

Difficulty: Moderately Easy

Things You’ll Need:

• Internet access
• Computer

1. Find out what version of Mozilla you have. Open the browser and click on the "Help" tab, and then drag down to "About Mozilla." You should get a page which lists the current version of Mozilla.
2. Go to the Mozilla support site. You can find a quick link to this free site in the Resources section below.
3. Find your version of Mozilla. Underneath the name of each version of Mozilla is a list of supported operating systems.
4. Choose your operating system. Find the name of your operating system and click on the Install link. You may choose to download the spellchecker first and install it later.
5. Confirm the spellcheck version. Read the filename in the download window and make sure that it is compatible with your version of Mozilla. Click "Install Now."
6. Wait for the download and install to finish. This may take some time.
7. Restart your browser for the spellchecker to take effect.

Tips & Warnings

• You may need to use the "Edit Options" button in the browser dialog window to allow the Mozilla spellchecker to be installed. If so, remember to refresh your browser page after you have given the site permission before trying to install.
• As newer releases of Mozilla Firefox and Thunderbird come out, features like spellcheck are being incorporated into the source code. If you have Mozilla 1.5b or higher, you do not need to add spellchecker, because this feature is already part of the code.
• Do not close your browser while the installation is happening. You may disrupt the installation and have to add spellcheck to Mozilla again.
