I tried to give feedback to say how horrible the changes are. This has totally messed up the performance of my computer and I have removed myself and found a new browser. I really didn't want to do that since there are many Firefox features that I found very helpful and I also felt comfortable with. You made it virtually impossible for me to express my concerns by making it a laborious task. I am recommending to all the people I work with helping them with their computer issues that they remove your product. Let me know when you roll out a version that works again.
