Login Page Not Loading Due to CSP Issue in Firefox
Published
I am experiencing an issue when trying to log in at login.mailbox.org using Firefox. The page gets stuck on the loading screen (.fullpage-loader), preventing access to the mailbox.
After inspecting the developer console, I found a Content-Security-Policy (CSP) error, which blocks inline event handlers (script-src-attr). The error message in the console is:
Content-Security-Policy: The page’s settings blocked the execution of an event handler (script-src-attr) because it violates the following directive: “script-src 'self' 'unsafe-inline' 'unsafe-eval' 'nonce-...'” Source: history.back();return false;This issue does not occur in other browsers (e.g., Chrome, Edge), suggesting that Firefox enforces CSP more strictly. It appears that JavaScript required to hide the full-page loader is not executing due to this restriction, leaving the page unusable.
The same problem 
No connection
Real-time notifications may not work
I'm also having problems with the settings page. I can't create aliases because the settings are in English one minute and German the next.
Reloading the page doesn't solve anything, and I can't use Deepl to translate it.

There is a problem when you logged out and later try to login again without closing the tab/window/browser. Not sure if this is what you experience. And the language issue is another bug.

I had a similar problem; that is I could not get to the mailbox.org log on page in Firefox but I could do so in Edge and Chrome. After some trial and error, in my case I found that the Mozilla VPN extension for Firefox which I was using was a key to the problem. More correctly, I think there was a clash between the Mozilla VPN extension for Firefox and the Firefox browser. The last time I had a similar problem, it went away when a Firefox update was installed. This suggested that the problem was with Firefox, not the Mozilla VPN. Anyway, this latest time (with the mailbox.org log on page), the problem went away when I disabled the exception for mailbox.org in the VPN Firefox browser extension. In summary, I think that sometimes when Firefox is updated, it introduces a clash with Mozilla VPN which is often corrected with the next Firefox update. The clash can sometimes stop you from accessing the mailbox.org log on page if you are using Mozilla VPN and the Firefox browser together.

Couldn't login the first time I tried using Firefox on opensuse Linux (neverending 3 dot sequence). Double-checked with Chrome, login via Chrome worked. Disabled all Firefox extensions, login worked. Re-enabled the extensions, one at a time, logging in each time in the process. When all Firefox extensions were enabled again the login magically worked.
