Ah, gotcha.

Could a grease monkey script do something similar? I'm probably just talking out of my butt, but it seems like GM can sometimes do things easier or better (or just at all) that extensions can't or won't do.

Reminds me of the episode of The Office where Jim tricks Dwight into being his own assistant.

Baby bitch. That's poetry.

The Notebook, but it's on the moon.

Since I'm able to share gif, jpg, png files with no problem, then, yeah, I'm going to say this is webp's fault. Yes, I'm blaming a file format. /s(?)

No, I don't hate a file format, I hate its lack of support.

Can you recommend a good one?

FB Messenger Lite is one of those that doesn't.

I know, and it's bullcrap.

I'm using FB Messenger Lite. Telegram may have the same problem, but I'm 100% on that.

Hadn't even thought of that. From what I've seen, changing the file extension just makes the file unusable.
