I don’t think so - from how i understand it, everything where you upload a file to a server to edit it there wouldn’t work at all.
The flow looks like this:
You select a file for upload - the browser creates a file in OPFS storage representing the original file - any change you make serverside are replicated to the copy in OPFS storage - when you save the file, you don’t actually have to download it, but the file gets moved from OPFS to wherever you save the file. This prevents long downloads, and the file in OPFS storage is encrypted because of HTTPS.
I looked it up - Firefox does not allow OFPS storage in private mode since November 2022 , so that is an option at least.
I wonder if librewolf has this option on by default

But only in private mode?
