i installed the latest version of ubuntu on another hard drive, and ever since i started working on it, especially with an internet connection i had strange issues coming up. for firefox the upper right google search box doesnt work, when i hit enter nothing appears. when i go to the system, places and applications bar above, it dissappears and reappears when i click on it or any of the tabs. also firefox has this strange issue of shutting down randomly. I also cant seem to download anything through firefox, can someone please help me?
