On ublock origins website about uncloaking canonical names they mention that your DNS address will be leaked if you use an extension based proxy. I have configured mine directly in the Firefox settings and i need to have my VPN enabled to access the proxy so i thought i would be ok. Later i stumbled upon this 2 year old post about DNS leaks. In the post they mention that they didn't use an extension based proxy. I also found this post about someone experiencing a similar issue as in the other post but he also had a VPN. I am wondering if my DNS will leak if i use firefox built in proxy configuration, a VPN and have uncloack canonical names enabled or have the problem been fixed. I have checked for DNS leaks on many different sites but i haven't found anything.

Using a browser- or system-wide proxy does not leak. Browser-wide used to leak with older Firefox versions but this was fixed in Firefox 80 (ref)
