"Save Page As" should do something about colons in the page title on non-mac/windows/android

"Save Page As" takes a page's title as file name. The file name is also used to store extra resources.

So when you save a page with the title "Foo bar", you end up with a "Foo bar.html" file, and a "Foo bar files" directory containing the resources of the html page. Links in the html are written as relative paths starting with the directory name.

Now, here's how things can go badly:

  • Open about:memory. Its page title is "about:memory"
  • Save the page as, and keep the default file name, which is "about:memory.xhtml"
  • If you check the directory where the file was saved, you'll also notice a "about:memory_files" directory.
  • If you open the "about:memory.xhtml" file, it will be unstyled. Why? Because the link to the stylesheet is literally "about:memory_files/aboutMemory.css", so the browser is actually trying to open the corresponding about: url that doesn't exist, rather than the relatively situated file.

I don't think there are ways to exploit this, because of the addition of the _files suffix, but this can be an inconvenience for users saving pages, where the associated resources are not accessed as expected.

Colons could be transformed into underscores for the file name, or the links could be rewritten to start with "./". The latter would seem cleaner to me.

I think this should go under File Handling, please feel free to change it if you consider that a different component is more suitable for this issue.
Also reproducible on Nightly 69.0a1(2019-07-01) build.

Sigh. This isn't an issue on mac/windows/android.

(In reply to Mike Hommey [:glandium] from comment #0)

The links could be rewritten to start with "./". [that] would seem cleaner to me.

I dunno, it's not necessary for 99.99% of relative links so doing it everywhere seems overkill. Doing it only where necessary in the webbrowserpersist code (which is generating the broken links here when we're using platform-valid filenames that include colons on Linux/BSD/...) is tricky. If you feel strongly, please file another bug - in Core :: DOM (which is where that code lives, for better or worse).

I'm just going to fix the frontend suggested filename sanitization to exclude colons everywhere (replacing with a space because that's what we do on all the platforms that already exclude it) to avoid this issue.
