HI.. I'm running Xubuntu 18.04.4 LTS & recently switched from waterfox to Firefox 73.0.1. I have been bugged by two problems that I haven't been able to fix myself & was hoping that someone here could possibly help. [ Problem_1. Sync has stopped working.... ] Whenever I open the synced tabs sidebar all I see is "Connect Another Device". On android I'm running Firefox Nightly version 75.0a1 & I've signed out & then re-signed in, but still nothing. The sidebar stays the same as the screenshot above. Both devices show under devices & apps & I can send tabs between both browsers. I just cannot use the synced tabs sidebar. I use sync daily & hope to find a fix soon. Here is the most recent sync log from about:sync-log. >> https://paste.mozilla.org/cXGtysBQ << [ Problem_2. Cannot fully use Instagram.... ] I can access instagram.com & browse through the site without any problems. However if I try to like, comment, share or follow I constantly get "Action Blocked" popping up & whatever I've just tried to do has been unsucessful. I can confirm that instagram works perfectly on both chromium & brave desktop browsers & also the official android app. I have attached two screenshots relating to both my problems & can confirm that uninstalling & reinstalling firefox did nothing. Many thanks in advanced for replying & helping me :)
