I have the spell check box checked on the addons page. I have the US English dictionary enabled. The spell checker will underline the miss-spelled words but when I right click to correct it no longer offers suggestions. Everything was working fine until the last update. How do I fix this?

First, check these settings: Type about:config<enter> in the address bar. If a warning screen comes up, press the I Accept the Risk button. At the top of the screen is a search bar.

Type: layout.spellcheckDefault Its values are; 0 Spell Checker Off 1 Check Only Multi-Line Input Boxes. 2 Check Multi And Single Line Input Boxes.

Also, check the spellchecker.dictionary entry.

Are you using the spell checker built into Firefox, or an add-on?

Do you have a dictionary installed and selected?

You can see which dictionary is selected if you right-click in a text area and open the Languages sub menu. At least one dictionary should be installed and have a check mark to indicate that it is selected.

  • open the "Add Dictionaries" link to install a dictionary if you do not have one.

The spelling checker is enabled if [X] "Check Spelling" in the right-click context menu has a checkmark.

You can enable or disable spell checking globally:

  • Options/Preferences -> General: Language and Appearance: "Check your spelling as you type"

You can look here for dictionaries:

Note that for spell check you need a dictionary. A language pack provides string translations for the user interface.

You can check the layout.spellcheckDefault pref on the about:config page.


Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
