I posted a long comment on GitHub via Firefox on desktop. The next day I visited that page via GitHub Mobile, I saw that somehow it was duplicated. Thinking it was an issue with my network, I deleted one. Oops, both were deleted.
I later visited the page via Firefox desktop, and saw that comment again for a second before it was gone. So apparently Firefox saved its cache before checking the GitHub server. Is there a way to get that cache? I visit about:cache?storage=disk and search for the issue number. There are several results, but the content seems like only in hex.
