I do not know, or just me, but when I turned on HTTPS filtering websites, after a few minutes after turning Cyberfox x64 browser crashes. After disabling HTTPS filtering is not present this problem. Secondly, there is a problem with uninstalling the current beta (I wanted to go back to the latest stable version). There is an error 1063 probably. I took advantage of AdGuard Uninstall Tool and after you restart the system, I can not install any version of the program. After cleaning the registry could arise a problem with the uninstall program?
