Ability to change the security level directly from the toolbar and also set per-site levels
Currently changing the Security Level in the Tor Browser requires clicking on the "Security Level" toolbar icon, going to "Advanced Security Settings", selecting the security level preset and closing the new Preferences tab which has been opened. This is not an intuitive process in my opinion, compared to when you can directly change the preset directly from the "Security Level" toolbar icon. This will allow quickly changing the preset and reloading the page. With TBB 10.5, there are already some UX changes, and I would like to see if this feature is implemented as well.
Also, there is no option to change the security level preset for a single domain only while in a session. Changing the preset in Preferences changes the security level for all the sites that are open, and will be opened in the future. Sometimes, a person would want greater anonymity and security on one site (which may be considered potentially harmful), and less security on one site which either doesn't work well with greater security, or one trusts the site. In this case, one would finer control over the security presets. Such a feature can be implemented in the toolbar menu as well, with an option to "Change the preset for this domain only".
Hope the team considers my opinion. Thank you.
