Since I upgraded to Firefox 90.0, my RSS feeds can not longer be refreshed in my feed reader. I get a 403 error ("access denied"). When I check the debug information on the URL, it says: '''Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”).''' I am using Feedbro on Firefox 90 on Ubuntu 20.04 on two different computers, and getting same problem. Clearing the cache, trying other feed readers, deleting cookies etc do not help. A sample feed URL: https://news.google.com/rss/search?hl=en-US&gl=US&q=mozilla&ceid=US:en In Firefox, I can open a tab and see the text file. But Feedbro, or any other reader, cannot detect the feeds on this page any more. Any advice? I absolutely rely on RSS feeds for my work. Thank you kindly!
