Hi Guys i need to customize the file name format while saving the E-mail.Please let me know if there is any Add-on to do the same..Thnxx

The error text"Import/export too;s could not be installed because it is not compatble with thunderbird 60.0." Please help

If you choose to run a pre-release beta then you must expect mainstream add-ons not to work.

It may work if you tweak the "max version" limit set within the add-on's xpi file.

Setting extensions.strictCompatibility = false should be enough.
