Summary
▶ Update:
This extension no longer works as of December 16th, 2020. Messenger made extensive changes to their user interface, including disabling KaTeX. Since the KaTeX preview was my main motivation for making this, I have no intentions to fix this extension.
However, the number of users has tripled (~30 to 100) since it broke, so I'm leaving this published on the off-chance that it still works for some people.
———————————————————————— ————————————————————————
Messenger has many different formatting options, such as bold, italics, strikethrough, monospaced code, and math formatting through KaTeX (a subset of LaTeX). It can be hard to know what a message will look like without sending it once, so this extension shows a preview of how each message will appear before you send it.
Note: the formatting only renders properly on web Messenger. Mobile Messenger does not show any of the formatting.
All previews are performed client-side. None of your information is sent to any third-party server.
