Greasy Fork

I'm hesitant to try this script because it disables the browser's Trusted Types protection and requests GM_xmlhttpRequest permission without using it, creating a significant risk if the script ever receives a malicious update.

It also says "Save As PDF" but it saves as markdown...

Output is poorly formatted, too. It adds "bashCollapseWrapRunCopy" at the top of each code block, as if it's reading the HTML from the page and then back-converting it to markdown instead of getting the actual markdown of each message.
