Good job so far.
As a practical matter, use of Sandboxie should prevent issues with AIS, as a similar issues can occur with Internet Explorer and Windows. Both the sandbox within AIS and Internet Explorer are integrated within each environment, so corruption in IE can adversely affect Windows operation, as can the sandbox feature if it is not working correctly within AIS. As the SafeZone Browser enables secure and protected financial transactions when it is working properly, this main feature is what AIS is really all about. So, as with IE/Windows operation, use AIS sandbox for what you really want to use it for.
Sandboxie will allow you to safely do everything else.
Sandboxie does not need to be run within AIS to be effective; it works just fine by itself. You can run your browser(s) of choice within it, and it will keep any changes to that browser from becoming permanent in nature. It is possible to set the sandbox to auto-delete on close of your browser sessions.
It seems there may be some issues with the browsers you are running; the version in AIS is Google Chrome modified to not have any add-ons running or enabled when in SafeZone and the AIS Sandbox is what one uses to run FF or other. So, with your permission, I'd like to have one of our malware experts to have a look at your system and see if, (if you think this may help you,) when he asks to run a certain program and a log is attached by you, to see if there is anything amiss with either your browsers, system, or AIS.
A certified malware expert will only be contacted if you say OK to do so.
Final resolution for now, may be one needs to wait until a fix is made for your specific issues in a later upcoming update, and run with AIS 8.0.1497 until that is done. Just be sure to use aswclear.exe as instructed when you move up one version number, from 8.0 to 9.0, so you get a clean install without the issues that happen sometimes from updating within the program gui.
BTW, to prevent auto-updating of your AIS program see the following .jpeg setting noted below:
