Thunderbird FileLink extension

There were several issues requesting this feature: https://github.com/mozilla/send/issues/847, https://github.com/mozilla/send/issues/496 and https://github.com/mozilla/send/issues/1353 and also BMO bug 1516252.

I have wanted this feature for years and since no one else has implemented it yet*, I decided to create a Thunderbird add-on/extension myself. It allows users to enter the URL of the Send instance they want to use, along with other info. It will then encrypt and upload the files to that Send server. It requires at least Thunderbird 78** and should support all v3 Send service instances. See my repository for more info. Here is an example of what the account management pages looks like:

I wanted to get permission to use the icon from this repository for the add-on. My repository is also MPL-2.0 licensed, so I believe there should not be any issues, but I wanted to check anyway, as I saw you had issues using the Firefox Send logo in this repository.

I also wanted to thank you for continuing to maintain this after Mozilla discontinued it! 🙏

At some point, I may submit the add-on to Addons.thunderbird.net (ATN), although I am currently still testing it. Feedback is welcome! If anyone wants to try it in the meantime, you can download it with this command:

git clone --recurse-submodules https://github.com/tdulcet/Thunderbird-Send.git

Then follow these instructions to install it in Thunderbird.

* Someone attempted to create a TB add-on here, but it uses the /share endpoint and thus does not actually encrypt the files before uploading them, which of course defeats the primary purpose of this service. It also is hardcoded to the discontinued Firefox Send service. ** The options page does not currently work in TB 78 because of bug 1641577, although the account management pages work fine. It only has a single minor option, which is not necessary to use the add-on. The bug was fixed in TB 86 Beta and should be included in TB 91.

Fantastic! Great work.

If you would like to close this issue, could it please be added on the Clients section of your README?

Sure. I can’t easily add this right now. Feel free to submit a PR for this in the mean time.

I published the add-on to ATN: https://addons.thunderbird.net/en-US/thunderbird/addon/filelink-provider-for-send/. It requires Thunderbird 91, which was released earlier this month. Feedback is welcome.

I also recently added a popup to extension so users can specify the download and time limits for each file before it is uploaded.
