Hi, I am a mac user, on mac os x 10.9. I recently upgraded my firefox to ver. 25.0 and this problem occurred. After inserting a URL into the location bar, I am unable to hit the arrow (go to the location in the address bar). Hitting enter doesn't do anything as well. The only way that I am able to go to a website is through google, through the use of instantfox. I was hoping for an update from firefox that would solve this issue, but i'm not hearing anything, therefore I decided to post a question. My sister, who is also on mac 10.9, also has the same problem with firefox after upgrading. Any help would really be appreciated as I don't want to be forced to migrate to chrome... :( Thank you!!!
