Several issues:
1. I agree with one of the posters who said that installing software on a person's computer without consent is NOT acceptable.
2. Firefox allows a setting which AUTOMATICALLY erases ALL browser history (not just cookies) upon exit. Safezone requires a manual action to accomplish the same task.
3. The bookmarks which were imported from Firefox do not show up on the toolbar (which they have whenever I have imported from Firefox to any other browser (IE, Opera, Chrome). There may be a way that I have failed to find which can accomplish this, but at this point, it is not done. Interestingly, Chrome did it automatically.
While #1 is profoundly disturbing, it is not a deal killer for me, although I fully respect that it could be for others. However, #'s 2&3 are deal killers. If Avast wishes to make a modern browser, it need to do what the other current browsers do with regard to ease of use.
At this point, it is staying on the computer as it does have a very convenient way to download videos from YouTube, but until the above issues are fixed, that is its only value to me.
