User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0 (Beta/Release) Build ID: 20140428193813 Steps to reproduce: Open a Firefox browser on ubuntu Open 2 tabs, tab1 and tab2 Take a WheelClick on tab1 and Quickly move cursor to tab2 Actual results: tab2 is closed Expected results: tab1 must be closed
Mozilla/5.0 (Windows NT 6.3; WOW64; rv:30.0) Gecko/20100101 Firefox/30.0 I was able to reproduce this myself on Windows, it's easy and you can move rather slowly and surprisingly still see the effect.
Can't reproduce with firefox-30.0.en-US.linux64 or 29.0.1. This must be a duplicate, see: * bug 997681 * bug 1001362 * bug 1015756 * bug 1019615

After reviewing those bugs, I don't think this isn't a dupe of any of them, and I have reproduced on two alternate linux systems (Arch and Ubuntu), I can follow-up with sysinfo and moz user agent as required. The closest bug is 1015756 as it may be related to the timing of the close animation, but ultimately this is a different problem as the issue here is the tab 'clicked' needs to be tracked instead of the tab under the cursor at the time the middle-click is actually processed.
User Agent Mozilla/5.0 (X11; Linux x86_64; rv:46.0) Gecko/20100101 Firefox/46.0 Build ID 20160106030225 Works for me on Firefox 43 and Nightly 46. @Reporter,are you still experiencing the issue on latest Firefox versions? - Firefox 43: https://www.mozilla.org/en-US/firefox/new/ - Nightly 46: https://nightly.mozilla.org/
Is the same effect for 'Mozilla Firefox 43.0' on Ubuntu.
Thanks for responding. I assigned this to Firefox: Tabbed Browser so people with more experience on this matter to be involved.
