why is page info modified time stamp my system time
When I right click while in a tab, then select 'view page info', the 'modified' field shows what I believe to be my system time.
This also occurs if I do page info on a tab that was long ago loaded.
I'd really like to be able to determine if a tab I'm viewing is 'current'.

"Modified" usually is defined by a Last-Modified header sent with the page by the server. If the server did not send that header, Firefox appears to improvise a value. Ideally, Firefox would report the time the pages were retrieved/cached as the document.lastModified time, but it doesn't seem to do that. Is that a recent change? I don't know...
I couldn't come up with a replacement in a quick search (e.g., when was this tab last loaded/reloaded). But maybe that's not your exact question.
Thanks for your help.
Yes, I want to know when the page/tab landed in my browser, so I can better know if I might want to reload the page.
Guess I'll have to do without.
The roundabout way would be to look at the about:cache page, but that's inconvenient. Perhaps an add-on could surface the information more easily, but I haven't heard of one along these lines. There are extensions that automatically refresh pages at certain intervals, but they might keep their own timer rather than extracting information from Firefox. Hopefully someone else has a suggestion or you could search on the add-ons site.
