I recently completed a Remove Cookies and Trackers disk cleanup and now I am unable to access Tumblr sites with the error "Unable to Connect" this occurs in both Firefox and Edge. All other sites work fine and I an access the site from other devices. Any help would be great.
You might check out this thread on the same issue. It seems to be McAfee Netguard blocking all Tumblr blogs as of this past week, rather than anything you did- https://community.mcafee.com/t5/LiveSafe/Blocking-Tumblr-Blogs/m-p/614507
