- tried to access the page in safe mode (all plug-ins disabled).

Since a recent update of Firefox (38.0.5) I have been unable to access my gmail inbox using the AJAX web client. The HTML simplified web client works. The behaviour I can see is like this: Firefox seems to be stuck in an eternal loop of redirections and the loading bar, once it has reached 75%, bounces left and right -- never going beyond 75%. In the Console log tool in Firefox, I can see the following error message when trying to resolve "gmail.com": "Content Security Policy: [my translation from French] The page settings have prevented a ressource from loading at[/my translation] https://s.rfnd.me/covus_wrapp.js («script-src https://*.talkgadget.google.com https://mail.google.com 'unsafe-inline' 'unsafe-eval' https://talkgadget.google.com https://www.googleapis.com https://www-gm-opensocial.googleusercontent.com https://docs.google.com https://www.google.com https://s.ytimg.com https://www.youtube.com https://ssl.google-analytics.com https://apis.google.com https://clients1.google.com https://ssl.gstatic.com https://www.gstatic.com blob: » ) Here are the actions I have tried in order to circumvent the issue: - cleared all cookies & cache; - repaired Firefox using the "Repair" function; - uninstalled, delete profile folders, reinstalled a newly downloaded version; - tried to access the page in safe mode (all plug-ins disabled). Not to avail. I am pulling my hair. Any help would be highly appreciated.
