Firefox comes with a lot of features by default and the list grows tremendously if you look at the available extensions that provides extra features that is not found in Firefox. One of the useful Firefox feature is the spell check where it auto checks the word that you type and if found that the word does not include in the dictionary, the word will have be underlined with a red wavy line to indicate that the word might be wrong and offers a few suggestion.

If you are a blogger or writes emails in webmail, you might want to remove those technical terms or jargon that are not included in the dictionary. This saves you time when you are checking for any typing errors. One example of a word that is commonly used but not included in the Firefox dictionary spell check is the word “webmail”. When you type the word Webmail, Firefox offers a few suggestion such as Web mail, web-mail, webmaster, webmistress and seamail.

Firefox Spell Check Exclusion

To easily add the word to dictionary all you need to do is right click on the red wavy line and select “Add to Dictionary”. This is easy and you might have already noticed this and done this. However if you have added a wrong word to the dictionary, removing it might take slightly more steps. You will need to go to your Firefox profile folder by typing %appdata%\Mozilla\Firefox\Profiles in the Search programs and files bar in Start Menu. Then there should be a folder with random letter and number. Enter the directory and look for file name persdict.dat. Open it with a text editor such as Notepad and the words that you exclude from spell check are listed there. The entries in persdict.dat are one word per line.
