Android phones feature some pretty neat predictive text features for typing with the software keyboard, but sometimes they don't contain words you need (or they add words you don't want). Here's how to edit your phone's predictive text dictionary.

Firefox's integrated spell checker is extremely handy for avoiding an embarrassing typo in an email, blog post or Twitter update, but after a while, the light red underline is easy to ignore. Fix that with a quick about:config tweak.

Firefox only: Firefox has long had a handy built in spellchecker, great for proof reading emails, blog posts and other communications. What if you want to use the built-in spellchecker on a static web page however? Use this bookmarklet.

Windows only: Freeware application Enso Words adds an always-accessible universal spell checker and dictionary to Windows. Enso Words is very similar to the much-maligned (by me, mainly) Enso Launcher, but focuses on, obviously enough, words. Highlight any text on your computer, invoke Enso Words, and type the spellcheck command for a quick spell check and autosuggest corrections. Enso Words also integrates with web searches at Answers.com to provide definitions or synonyms of either selected words or words you type into the define command.
