> What are you doing in the interim? icecat with a set of extensions?
I run `tor' from the command line. It opens up a SOCKS proxy at port 9050. I set that proxy in Icecat and use it along with Private Browsing mode. I use the extension "MM3-ProxySwitch" to make switching proxies convenient. I use an old version of uMatrix to block javascript. When last I checked (many months back), the latest version of uMatrix wasn't working in our Icecat. I also use the extension "Self-Destructing Cookies" to automatically cleanup cookies once I don't need them (after I close the tab of a website).
