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 submenu. You can open the "Add Dictionaries" link to install a dictionary if you do not have one. Make sure that [X] "Check Spelling" in the right-click context menu has a tick.

Thank you for your reply and got the dictionary and works now in some sites but not all, thanks again for your help.

Did you check the right-click context menu in the text area on pages where spell checking doesn't work and make sure that all settings are OK?

Cor-el I don't get a context menue when I right click all I get is cut copy paste delete or select all and since my last post to say it was working ok it's now stopped working urrr so don't know why, thanks again for your help with this.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

• Don't make any changes on the Safe mode start window.
