<p>Thunderbird 77 beta 1 is here. There's not many changes for
WebExtensions in this version, but there is a significant one.</p>
<ul>
<li>Several improvements to tab handling and events.</li>
<li>Content scripts in the compose window. This allows you to
interact directly with the message being composed, and should
solve a range of problems.</li>
</ul>
<p>Here are the details:<br>

<p>Looking ahead, with Thunderbird 78 being the next release, I
won't be working on any new additions for a while (other than the
compose attachments API, which is already finished). Instead, any
time I have for WebExtensions work will be spent making sure
existing things work as they should – like the changes to tab
events mentioned above. I already have a long list of bugs, so
I'll be focussing on the ones that make the most difference to the
most people. Sorry if your pet problem doesn't get fixed.</p>
<p>Lastly, thank you to those who have tested new additions and
pointed out problems or things that have been missed. Thank you
especially to those people who have contributed fixes to the
issues they see. You know who you are.</p>
