From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0rc3) Gecko/20020523 BuildID: 2002052309 When you middle-click on a tab it closes and the tab that is visible/becomes visible will be loaded with some random (sometimes invalid) url. Reproducible: Always Steps to Reproduce: 1.Open a few tabs 2.middle-click on any of them Actual Results: 1. Tab 1 closes (as expected?) 2. The tab that is visible (was or became visible) is loaded with some new/old/ivalid url Expected Results: This is unclear, but I suppose only tab 1 should close an nothing else. I have "middle click to open in new window" enabled.

I am also seeing this bug in conjunction with Bug 117681. After some intensive (and annoyingly involuntary) "testing" I noticed that at least for me the result is the same. This is how it works: When I middle-click on a tab and close it, my current tab gets to thinking: - "hey someone middle-clicked so we better load that url" - "hey, there is no url there! let's check if anything is highlighted and then check the clipboard" - "Something is highlighted, we'll just stupidly asume it's an url and load it" OR - "We found some stuff on the clipboard, we'll try to load that as an url!"

workaround: user_pref("middlemouse.contentLoadURL", false); *** This bug has been marked as a duplicate of 107147 ***
