This is a regression since Firefix38.

Steps to reproduce:
1. Open web page
  (e.g http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/ )
2. Right click on the page and choose "View Page Info"
3. Remember Modified time
4. Close Page Info dialog window
5. Repeat Step 2 and 4

Actual Results:
The Modified time change every time of opening the Page info dialog.

Expected Results:
The Modified time should not change every time of opening the Page info dialog.

I think the best thing here might be to simply Omit the "Modified" field if there's no Last-Modified header.

Although Firefox is obliged to follow the idiotic specification at the JavaScript level, that doesn't to me mean that the Firefox UI should report invalid data to the user. If there's no Last-Modified header, the interface should surely decline to show the modified date. The Referring URL line is omitted when not relevant, so could the Modified field also be simply omitted when not relevant?

Personally I'd prefer to see Access time (i.e. how long has this tab been open) but that's just me :) That's what I've always looked at this field for, but nothing useful has appeared in that field for a long time. (The front page of my own site does, however, set Last-Modified.)
