Aargh! Firefox 3.6 is adding tabs in the middle!
I , presumably along with a lot of other people upgraded to FireFox 3.6 this week. Most of the changes are 'under the bonnet' so to speak; but there are a few differences in the UI as well.
Now, when you open a link as a 'new tab', the tab appears next to the one you currently have open; instead of at the far right hand end of the bar as before.
If, like me, this gets your goat then there is an easy solution.
Type about:config into the address bar, click "I'll be careful, I promise" on the nanny screen and filter the results for browser.tabs.insertRelatedAfterCurrent . Double-click the entry to flip it from 'true' to 'false', and you're done.
