Hello to everybody! My first question here and i am really hoping for an answer... So, here is the problem. I use Ubuntu 12.04 Kiosk with Firefox 28 (do not ask why and how, it just works) and what i wanna do is pretty simple: set 2 tabs as homepage. Pipe character would be the solution for me but here is the tricky part. When i set in user.prefs file the two url's, firefox starts normally with 2 tabs open (so far so good) but when session is killed, firefox reopens with this link in address bar http://www.mozilla.org|http://www.google.gr For some reason that i still can not understand, it reads those 2 url's as one and it tries to open them - with no success of course. So what i wanna do is pretty simple: Ubuntu Kiosk running firefox with 2 tabs as home page, even when session is resetted after 1 minute (that's the threshold i have stated). Any help???
