This update contains many small changes that are purely technical and shouldn't have any visible effect, and it adds support for Facebook "pfbid" URLs. If you do not care about or use Facebook, you can stop reading there.
Concerning Facebook, it has come to my attention that they have recently started obfuscating their URLs, encrypting them with an unspecified algorithm that generates a different value every time. According to
Facebook's public announcement, this change was effected to deter what they call "unauthorized scraping" and is meant to "protect people’s privacy". Cynics will be quick to remark that Facebook's business is based on monetizing its users' information, and that change just happens to interfere with Firefox's query parameter stripping,
a privacy-enhancing feature that had been released just a few weeks prior, casting doubt on whether encrypting a URL's identifier is meant to protect users or optimize Facebook's money maker.
Facebook/Meta denied via a spokeperson that this has anything to do with blocking privacy features.
Starting with this version, embedding content using Facebook "pfbid" URLs is now supported. The add-on will attempt to revert the encrypted value to its canonical ID whenever possible.
