When i checked two weeks ago, there was a bug that when opened a notebook with large number of cells(~200), in firefox, it would freeze for about 10 seconds if the window was resized. The problem, as i know, only occurs in Firefox, not in Chrome.

This was problematic, especially for me, as I open documentation on other side of the window and keep resizing the window as part of my habit. But, overall JupyterLab was great. You can work on the same notebook side by side too and has a file manager/viewer panel.

Please try it again. In the last few weeks we've made some changes that drastically sped up things in Firefox, and we have plans for more changes in the pipeline.

See https://github.com/jupyterlab/jupyterlab/pull/3805 and https://github.com/jupyterlab/jupyterlab/pull/3802 for more details.
