Fixed some punctuation issues.
(For developer information about Thunderbird 61 and beyond visit the [[Thunderbird/Add-ons Guide 63|Add-ons Guide 63]]. Note: Thunderbird 61 and 62 betas were skipped. The next beta after 60 is 63.)
'''Ask Questions, Get Help''': Developers are encouraged to ask for help and advice in the mozilla.dev.apps.thunderbird newsgroup. (, see [[Thunderbird/CommunicationChannels#If_you.27re_a_developer|Communication Channels]] . Please check this document and ask questions in a forum before filing a bug report. Also, if you target version is 60, test and fix your add-on using [https://getthunderbird.com version 60 release], not nightly builds or beta.
'''Legacy, pre-version 57 add-ons''' - '''Thunderbird 57-60 (and Seamonkey) <u>still support</u> legacy add-ons''' (except binary add-ons, see [[#Removed_in_mozilla53|below]]), but all add-on authors must check to see whether code changes are needed. The complexity of the add-on determines how it is affected - many add-ons are not heavily affected, some not affected at all. '''Some add-ons do not need any code changes, and some only trivial or minor refactoring or name changes. Some need to adapt to changed interfaces. Some only need changes to startup and intialization, others may need more extensive changes.''' A non-exhaustive list of of things to be modified is below. Every beta from 57 to 60 delivered changes. So for example if your add-on is compatible with beta 58 you may still need to make further changes. Example changes to version 59 involve {{bug|1414398}} default preferences, and {{Bug|1419145}} menu to access add-on options and tab options.
