I am not sure if this bug has already been filed, there are a lot of "view source" bugs but it doesn't seem to match the ones I looked at in a quick search. If I have a .html page "A" that generates a new window "B" via Javascript (vs. one that originates from a server), then the "URL" of the new window "B" is the same as the original web page "A", and: 1) If I choose "Save As" from window B, I get the HTML source of window A. (This has been the case in FF2 & is not what I am reporting) 2) If I choose "View Source" from window B, then Save As from the view source window, I get this message: "[filename] could not be saved, because the source file could not be read. Try again later, or contact the server administrator" I use (2) to get around the issue of (1) when I am trying to save a copy of autogenerated windows. Please fix. :( Reproducible: Always Steps to Reproduce: 1. 2. 3.

Could you attach a testcase to this bug?

Sorry :). Regression range (when it just stopped working): http://bonsai.mozilla.org/cvsquery.cgi?module=PhoenixTinderbox&date=explicit&mindate=1169784900&maxdate=1169786519 Caused by Bug 368160 ?

After it stopped working the behaviour changed a few times over time.

I guess View Source isn't giving its cache key to the Save function?

I'm assuming the issue Tantek is seeing is the same as the original issue (which involved document.write / wysiwyg URLs). Maybe it's not, since the wysiwyg thing seems to kinda work now.

No idea; someone would have to step through exactly what "save" in the view-source window does....
