Todoist in Firefox will not load beyond starting screen
I tried to log into Todoist both via the web interface using firefox and via the firefox plugin. In both alternative it does not progress after the screen with the TD logo and the 3 little squares beneath. I disabled all possibly blocking add-ons in firefox (like noscript, request policy etc.) but with no success. However Todoist runs on a different firefox profile without problems but this is no alternative for me to use.
Do you have any ideas to help me solve this issue?
