When a window is open and I try to go to a new bookmark or a link in an existing site, the new window opens behind the old window.
It isn't every time, and sometimes doesn't happen for a long time, then I'll go to a bookmark or toolbar link and the new window opens behind the one I was on. Example: I just opened a second window (CTRL N) and clicked on a bookmark. It opened a new window behind the one I'm on as I type this. I did the same steps again and it opened the new window in front of this one. It doesn't seem to make any difference which site I start from or go to or if I use CTRL N or let the bookmark do the opening.

Do you have Options>Tabs>"Open new windows in a new tab instead" selected?
This can happen if you have a tab open in the main browsing window that uses the plugin-container process (e.g. Flash).
That wasn't the cause, but it's good to know it could happen then.
No it hasn't been selected. Should it?
