Status in “firefox” package in Ubuntu: Confirmed Bug description: I have to say that by far, this upgrade to 11.10 is the worse yet. Since upgrading from 11.04, which also had problems, I have had nothing but problems. It remindes me of the days with Windows when my computer was bogged down with spyware, cookies, viruses and what ever else was going on. My screen freezes repeatedely and my computer runs choppy. I have to reboot at least 3 times a day because I can't get a cursor. When I open Libre Office documents it takes more than 10 seconds to open and my computer sounds like it's on it's last leg struggling to open that document. I am experiencing delayed typing, screens fading in and out, the launcher sometimes not opening or not closing. I write papers everyday and my computer is making tedious work a lot more frustrating. I want to switch to another operating system, but I have no idea as to which system to switch to. I love Ubuntu, but this latest update makes me extremely frustrated and crying the way I did when I used Windows. Is this a problem that can be fixed or do I really have to find and switch to another operating system? Thank you.
