Hi there,
I hope that I’m right in this category with my issue. I’m runnning Jupyter Lab on my Mac (10.14) and have the problem, that whenever I’m editing a cell and hit SHIFT+ENTER the cell is not executed, only when I mark it. I’m using Firefox 73.0.1 (latest on Mac). Possible blockers like uOrigin are disabled for everything running on localhost.
Anyone else encountering such an issue?
Many thanks in advance, regards, Thomas
Hi @mosesontheweb, can you open the Javascript console in your browser and let us know if there are any errors or warnings ouput to it?
Hi,
this thing makes me crazy. I used only notebook for a while where this problem did not occur. Now I started Lab once more to provide you some information, but for some strange reason it works now. 
Whenever it occurs again, I’ll try to post a follow up.
Regards, Thomas
Thanks for following up @mosesontheweb, seems like this is likely the same issue as https://github.com/jupyterlab/jupyterlab/issues/7902 .
