Hi,

Please check if this happens in Safe Mode.

Yes it is still a problem in safe mode.

You can try deleting the persdict.dat file if it exists in the profile folder: Help (Alt + H) > Troubleshooting Information > Open Containing Folder. The persdict.dat stores the manually added entries. Also try toggling the Check my spelling as I Type option on and off, restarting after each time.

Firefox Profile Folder & Files

Hi again

Thanks for your suggestions but they have not helped.

I deleted the persdict.dat file and un-ticked the 'spell check as you type' box, saved that, then opened options again and checked the box and saved that, then restarted firefox. The spell checker works manually but not as I type. I have an idea that this started with the latest update. Could this be?

Regards Colin

"The spell checker works manually but not as I type." Is there a chance that you have installed another spell checker? You can try to update that. Firefox has an in-built spell checker which works automatically once activated and perhaps there is a conflict after the Firefox update.

You have done it!!!

Thanks . . . I installed another dictionary (Australian) and now it works perfectly.

Thanks again for your time and assistance

Colin

You are welcome :)
