Youtube Thumbnails in Thunderbird

Install

• Make .zip containing all the files in the zip root (downloading the project as zip creates a project dir which will prevent Thunderbird from reading the files)
• Rename with extension .xpi (appears to be optional)
• Add in Thunderbird as extension from file (Add-ons Manager -> Gear Icon -> Install Add On From File)

You should be able to see the thumbnails added to any feed coming from a YouTube channel.

Adding YouTube Feeds

You can add YouTube Feeds to Thunderbird with the following URL:

https://www.youtube.com/feeds/videos.xml?channel_id={CHANNEL_ID}

Where {CHANNEL_ID} is the unique id for a channel.

To get the channel ID, you can use the following command from cli:

curl -sfLS {CHANNEL_URL}  | grep channelId | sed  -n 's/.*<meta itemprop="channelId" content="\([^"]*\)".*/\1/p'

where {CHANNEL_URL} is the url for the channel you want to add in your feed.

I think there are more convenient ways to do this without command line but I'm not aware of them personally (you can suggest them here if you want).

About

I have no plans to make this an official extension, but I have interest in maintaning this in case there are bugs.
