Previously with older Firefox 3.x and TMP I did not have this issue, and I believe I'm using the same settings, although I know much has changed with FF and TMP so I now come to you for advice!
Anyway, the issue is when opening a new tab, focus is no longer automatcially on the URL bar, so when opening a new tab I must manually focus on the URL bar, previously I could open a new tab and start typing directly into the URL bar.
I want this functionality back, and I think it's my current TMP settings are what's causing it to not work for me because if I disable TMP this happens correctly.
Current TMP settings attached, thanks for your help!
Currently using latest version I believe - 0.4.0.3pre.120627a
