TST displays instead the generic gray globe icon. (When you add ublock to the mix it gets worse and will include sites like Amazon, Google, Bing, and Youtube.)\r\nHowever, the icons are showing fine in the Firefox tabs at the top and on bookmarks. I can also browse to the actual favicon.ico of these sites and see it displayed in the browser.\r\n\r\n## Steps to reproduce\r\n 1. Start Firefox with clean profile.\r\n 2. Install TST.\r\n 3. Turn on tracking protection in Firefox.\r\n 4. Browse to Twitter, Facebook or eBay.\r\n\r\n## Expected result\r\n Website's favicon to be displayed in TST tab.\r\n\r\n## Actual result\r\nGeneric gray globe icon displayed in TST tab.\r\n\r\n## Environment\r\n * Platform (OS): Win7 pro\r\n * Version of Firefox: 57.0.1\r\n * Version (or revision) of Tree Style Tab: 2.3.0\r\n"},"comment":{"url":"https://api.github.com/repos/piroor/treestyletab/issues/comments/351443808","html_url":"https://github.com/piroor/treestyletab/issues/1654#issuecomment-351443808","issue_url":"https://api.github.com/repos/piroor/treestyletab/issues/1654","id":351443808,"user":{"login":"piroor","id":70062,"avatar_url":"https://avatars2.githubusercontent.com/u/70062?v=4","gravatar_id":"","url":"https://api.github.com/users/piroor","html_url":"https://github.com/piroor","followers_url":"https://api.github.com/users/piroor/followers","following_url":"https://api.github.com/users/piroor/following{/other_user}","gists_url":"https://api.github.com/users/piroor/gists{/gist_id}","starred_url":"https://api.github.com/users/piroor/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/piroor/subscriptions","organizations_url":"https://api.github.com/users/piroor/orgs","repos_url":"https://api.github.com/users/piroor/repos","events_url":"https://api.github.com/users/piroor/events{/privacy}","received_events_url":"https://api.github.com/users/piroor/received_events","type":"User","site_admin":false},"created_at":"2017-12-13T16:26:56Z","updated_at":"2017-12-13T16:26:56Z","author_association":"OWNER","body":"Due to restrictions of WebExtensions APIs, addon must fetch favicons with actual HTTP(S) request, but those requests are blocked by Firefox itself.
