Old, incorrect comment

I can replicate this as well on Firefox, although with a different error:

GET
https://matrix-client.matrix.org/_matrix/client/v1/media/thumbnail/t2bot.io/5a3a2939f12126d8ce106385831867d1d6cdc8161771316280532402176?width=100&height=100&method=crop&allow_redirect=true
NS_BINDING_ABORTED

I'm actually having a hard time replicating this error. After turning off uBlock Origin and Firefox's Enhanced Tracking Protection, everything works fine now.

@diamondburned btw the Firefox instance that I tried here (alongside LibreWolf) was a fresh install, with all the vanilla settings.

Can not reproduce on the Firefox.
