I'm using Firefox 3.6.6 on Windows XP and had a strange problem now: I worked on many pages during the day which were still using interactive popups (i.e. user has to click on image to popup opened with
window.open) to display information (popups linking to bigger versions of images). So during the afternoon I opened like 60 of such popups but usually closed them immediately after verifying the content was there.
Before finishing work, I closed my last two normal browser windows (with their tabs, the other popups were long closed). Firefox was closed and that point and not running anymore (verified with task manager).
I had a reason do immediately start Firefox again when suddenly about 60 windows were opened:
I closed them all manually and after re-starting Firefox, they're still there.
Firefox opened all Popups again I had open during the afternoon, even though I closed them long before finally closing the last window.
My settings are to open my windows from the last session, but that case the windows weren't open anymore when I shut down FF.
I managed to fix this by setting When Firefox starts to Show a blank page , shut down Firefox, start it. No further windows were opened. I than set When Firefox starts to Show my windows and tabs from last time
But how's that possible, some kind of bug or an error on my side?
