I realise that this is farily old, and that the person who posted the comment probably no longer cares, but it might help someone else to know that many different file types can be recovered.

That’s not actually a text post, that’s a PNG image – The IHDR IDAT and IEND are all chunks that make it up. It’s actually possible to recover that data, I did so by removing the non HEX parts, and copying the remainder into a HEX editor.

It turns out that the image is 6×6, and contains a grey, aliased, diamond / circle on a transparent background. Somehow I doubt that this is what you intended to recover.

This is a great tip, but it didn’t work for me: it turned out I had disabled my cache at some point, so all I got with “about:cache” was a page saying “cache disabled”. Well, I re-enabled it for next time… (about:config, and searching for cache turned up 2 non-default entries which were set to “false”; I reset them there).

Hi Trevor, yes, that is a great (and much easier) option if you happen to have the page still open in a browser window

The method described should work if followed correctly. Unfortunately, if it doesn’t work as described, it’s possible that you have some characters that are not being picked up in the regular expression. You’d need to write a different regular expression in that case.

Regular expressions can be complicated to write so it’s hard to say exactly how it would work in your situation.

For instance: How can you recover the original content of the following???

You’ve just saved me hours of re-writing a post that I idiotically deleted without thinking when tweaking my categories.

If you’re interested, I owe this post to you:

(Please do delete if you’d rather no links in comments!)

Thanks x10 — I aspire to write blogs posts this useful.
