How can I see seconds in browsing history
I need to figure out how to see seconds in the timestamp in browsing history. e.g. "9:34:45AM"
Although possibly not related to your problem, I have to remind you that the version of Firefox you are using at the moment has been discontinued and is no longer supported. On top of this, it has known unpatched bugs and security problems. I urge you to update to the latest version of Firefox, for maximum security, stability, performance and usability. You can get it for free, as always, at getfirefox.com.
As for your question, I doubt seconds are saved to begin with. I can't help you with that, I'm sorry.
The time is saved in 64 bit EPOCH format in micro seconds: 1279839326979821 , that is Thu Jul 22 2010 22:55:26:979 GMT in Milliseconds. So seconds shouldn't be a problem with a program that can decode them.
