I'm having a really hard time trying to put proper terms into my request. Please bear with me. I believe it's a version or two ago that Firefox started imposing an arbitrary limit on how long I could explore in a pulldown bookmarks menu before it disappeared. I believe that earlier this wasn't the case: that once I was searching around among bookmarks they would be available to me to mouse around in for as long as I needed. Now they self-retract after a few seconds. Is there a hidden pref to remove or greatly increase the time before the automatic withdrawal of bookmark menus while in use occurs? I hope I'm being clear about this. I'm sure my terminology is less than accurate. Thanks
