Dear support-team,
we have the follow problem. The follow Session-Timeout messages occures sometimes, if we try to add a picture or file to a article.

The message says something like: "Your Session is terminated. Maybe you need to send the form again or reload the page."
We try it by the follow way. We enter into the edit-mode and try to add it by using the upload-function for files and pictures, like this picture shows.

We need to close the upload-dialog. We leave the edit-Mode. And try it again. Sometimes it works by the second try and sometimes not... We need to try it again and again. The user-session isnt timeout out. The user is not logged out and there is not much time left between the actions. We are doing the described actions continuous without breaks.
We are using:
- Confluence 6.0.3
- Browser: FireFox Quantum 59.0.3
I liked to upload the current support.zip. But i dont find a possibility to upload a file.
However, how can we aviod this behaviour?
I`m looking forward to get your help.
Kind Regards
-Knut
