Henri - are you still on Firefox v28 or are you now on FF v29? [If you have set your computer for automatic updates you should be on v29 now on which the UI has changed]. If you are on v29 you can easily get the new Firefox interface to look the same as v28 by following the instructions on https://support.mozilla.org/en-US/k...ox#w_restore-tabs-on-bottom-and-other-options Which I have done and fiddled around according to the instructions until I have v29 looking exactly as I want! I originally had the Tab bar problem on v28 as I had forgotten to prop the keyboard up on end when I moved from the table and Pereg decided to put her paws on it to look at what was on the monitor... she also boogered up Thunderbird in the process... and I had just sorted that lot out when I changed to v29 and did not like it!
