Can not add attachments

[alexandergrein]

I just started with the free jira cloud account and created some projects, boards, tasks and stories.

All this worked without problems.

After this I tried to add some screenshot to a task, but it's not working.

The sceenshots are about 1 MB and I already checked the max. attachment site inside system settings. Even files with some kb do not work.

After dragging the image into the attachent dialog, the images first appear in a light transparent look.

After pressing the "insert x files" button, some seconds later an error message appear in the lower left corner:

We couldn't save your attachment
Reload the issue then try adding it again.

I aready tried to roload the issue, but it's always the same.

Try clearing your browser's cache and cookies in your Firefox or run in Firefox private mode to see if it is caused by the browser's extension.

The problem only exists under Firefox (I use version 74.0)

With Chrome (80.0.3987.149) it works.

Do you have any plugins running? If so turn them off and try again?

You got it!

It was a plugin ("Cross Domain - CORS") who made the problems.

After deactivating upload works fine also in firefox :-)

Thanks, for your help!
