Laptop, mobile, bad line; it’s annoying if the page (which should already be in cache since i opened it hours ago) says “No internet :(” just because it got unloaded.

And yes, “save webpage” solves that but

1. i have to think of it beforehand
2. the site is already there, in the freaking cache.

In short, i want to use Firefox as the document viewer and downloader it is, instead of a webapp platform or whatever it wants to be.
