I suggest to do it like Chrome does, show me the source. Maybe it caches the original source, I don't know, but I can't imagine that's expensive (given all that Firefox caches on each tabs ...).
Caching the original source can in fact be pretty expensive in a lot of cases. Which is why Firefox tries to put it on disk, not in memory. But, again, if the user then explicitly turns that off, then Firefox doesn't do it.
The key part here is that this bug report is about a situation in which the user explicitly changes the browser's default settings to not store stuff. And then the browser ... doesn't store stuff. Shocking, I know.
