Hey @Tinnyx, I've been using this plugin for years now and I'm not planning to stop doing so despite it no longer works with the current version of TB.
Fortunately it turns out it is enough the update the plugin's metadata as described here: https://developer.thunderbird.net/add-ons/updates/overlays

I took a stab at it and here is a manifest.json which works for me (please note that I've added some icon sizes):
{
"manifest_version": 2,
"applications": {
"gecko": {
"id": "keepintaskbar@zilak.sk",
"strict_min_version": "68.0"
}
},
"name": "Keep in Taskbar",
"description": "A simple plugin that makes the Close button behave exactly like the Minimize one.",
"version": "2.0",
"author": "Martin Žilák",
"icons": {
"32": "chrome/content/icon32x32.png",
"48": "chrome/content/icon48x48.png"
},
"legacy": {
"type": "xul"
}
}
Would you care to release a new version, using the above manifest? (I hereby give up any rights to it, so please use it as you see fit.)
Thank you,
