When editing a previously composed message the pop-up doesn't show the old values

A user reported this issue via email. I am able to reproduce it:

Since the update to 10.4.0, "Send later" forgets the selected sending time (default time now "5 minutes") for scheduled messages already placed in "Drafts".

Previously, I could make changes afterwards (e.g. correct typos) and simply click on "Send later" again without having to re-enter the originally scheduled time.

This issue should be fixed in release 10.4.3 of Send Later.

To check what version of Send Later you have:

• Open the Add-ons page in Thunderbird ("Add-ons and Themes" from the corner "hamburger" menu).
• Click on Extensions on the left if you're not already on the left if you're not already there.
• Find Send Later in the list of extensions and click on it to open its details page.
• The version number should be displayed there next to "Version".

This release is not yet available for download from addons.thunderbird.net, but you can download and install it from its GitHub release page as follows:

• Download send_later_10.4.3.xpi to your computer. (If you are using Firefox, make sure to right click on the link and select "Save Link As..." rather than just clicking on it, because otherwise Firefox will try to install it as a Firefox add-on.)
• Open the Add-ons page in Thunderbird ("Add-ons and Themes" from the corner "hamburger" menu).
• Click the gear icon at the top and select "Install Add-on From File...".
• Browse to and select the downloaded file.
• Click through the installation pop-ups.
• You can delete the downloaded file once you've installed it into Thunderbird.

To subscribe to future beta releases (we love beta testers!), download and install send_later_beta_10.4.3.xpi instead. The advantage is that if there's a bug that affects your workflow you'll help find it and get it fixed quickly. The disadvantage is that bugs are a bit more likely in beta releases. You can unsubscribe from beta releases at any time by downloading and installing send_later.xpi or installing from addons.thunderbird.net.

Note that this is a prerelease. While we make every effort to ensure that prereleases are stable, they are a bit more likely to have bugs, so proceed with caution.

If you prefer to wait, the release will eventually be available on addons.thunderbird.net, and unless you've turned off automatic add-on updates, Thunderbird will eventually update to the new version automatically. To update immediately once it's available:

• Go to addons.thunderbird.net and confirm that release 10.4.3 is available for download there.
• Open the Add-ons page in Thunderbird ("Add-ons and Themes" from the corner "hamburger" menu).
• Click on Send later.
• Click the gear icon and select "Check for Updates".
• The add-on should update and then you should see the message, "Your add-ons have been updated," next to the gear icon.

Please let me know if you still see this issue in this release.
