Avoiding Firefox Page Loading Errors
In some versions of
Firefox, a known issue with the browser console can trigger
HTTP 401 errors that cause
Service Board to freeze. When the
Developer Tools tab group (
Inspector,
Style Editor, and
Debugger) is visited,
Firefox tries to load source maps for CSS/JavaScript files that return a
401 error and reset the
JSESSIONID(httpOnly cookie, SameSite=Lax) value. This known issue is reported in
Bug 1630773 at
https://bugzilla.mozilla.org. Until the bug is fixed, you can use any of the following workarounds to avoid this issue.
Workarounds
• Do not open the Firefox Developer Tools tab group while using Service Board.
• Before you log into Service Board, in the Developer Tools tab group, do the following:
◦ On the context menu, click Settings, and then under Advanced Settings, clear the Enable Source Maps check box.
◦ On the Console tab, disable the CSS tab.
