if I open a mail compse windows and type "one" on a line and click the first two buttons immediately the text displayed changed. Obviously the other two will do nothing with out a whole paragraph of text to work with.

Have you tried restarting in Safe mode? Hold the shift key when clicking to start Thunderbird and continue in safe mode when prompted.

Thank you Matt, I did input text before trying to make a list and changing the indenting but it did not work. After your suggestion I did open Thunderbird in Safe mode and tried the same tests but it did not change the outcome.

Yes three ways

• Hold shift while starting Thunderbird
• Choose restart with add-ons disabled from the help menu.
• Start using the command line switch -safe-mode https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options

But this is all documented in the knowledge base https://support.mozilla.org/en-US/kb/safe-mode-thunderbird#thunderbird:mac:tb38

Dear Matt,

Thank you for replying. As I mentioned I did enter Safe Mode, however, this did not solve the issue nor produced any different results.

Thanks in advance for any further help.

Best regards,
