I have just become introduced to Jupyterlab through the GoPiGo robot and I have seen some issues regarding Firefox and Chrome.
When I first loaded Jupyterlab from the robot as a total newbie having never seen JupyterLab, I was very frustrated to find that any attempt to create a new text file or notebook gave me a 403 forbidden error. My default browser is Firefox Developer Edition. After some research I found on github some discussion of others who had the 403 problem and one suggestion was to use Chrome instead of Firefox and once I did that everything was fine.
What I surmise happened is that when the jupyterlab server first launched on DexterOS, it was “in” some read-only folder – I don’t know what – but the file browser panel was showing me nothing but a couple of files whose names I think started with underscore. After opening with Chrome the file browser had me in the home folder and I could see all the files and folders that I should see and I could no longer find the two files I first saw. Subsequently Firefox also behaves properly.
My second issue has to do with installing JupyterLab on OS X. I have posted a separate issue about pip3 not installing /usr/local/bin/jupyterlab. But this issue has to do with ~/Library/Jupyter/runtime/nbserver-78747-open.html. With Firefox opening that html file after launching the JupyterLab server does not redirect me to the server and does not show me a link. With Chrome it does show me a link that takes me to the server.
So I am just getting started but already I have seen a couple of issues where Chrome works and Firefox does not and I am wondering why that might be the case and what other problems one might encounter in the future.
