Does Mozilla come with a spellchecker?
A spellchecker is being developed by the Spellchecker project. This is early beta-quality software, and should not be expected to work flawlessly. Testing builds are currently available for Windows and Linux (Macintosh help is wanted). Expect bugs, and please report new ones to the Spellchecker project. Help in programming for the spellchecker is also welcomed. If you download the spellchecker for testing: Make sure that ‘Check spelling before sending’ is checked under Edit | Preferences | Mail & Newsgroups | Composition. When you first run the spellchecker, select a dictionary from the drop-down list on the bottom left of the pop-up panel (it defaults to ‘Download More’). If the spellchecker does not save your user dictionary, add this line to user.
