Kaggle versions page takes minutes to load in new Firefox profile, not on Chrome
I'm using a kaggle "kernels" (code notebooks). When I click the number of notebook versions (to view the past code runs and results) in the top right corner of the page (https://www.kaggle.com/<user>/<notebook>/edit -- I unfortunately can't share my own notebook), the page very often takes at least 30 seconds to respond to most clicks (like clicking a particular run to cancel it or see its results). Sometimes I give up before it loads. I think it might get worse if the number of code runs is close to 100. The issue remains even in a fresh Firefox profile, even after a reload. Chrome has no trouble with the same exact page.
macOS, Firefox 101.0.1 (64-bit)
