Downloading html file from file explorer opens file in new tab instead of downloading

[kevmk04]

I have an .html file that was generated by the plotly offline.iplot function. My typical workflow is to create the file from a notebook and download the html file to share with colleagues. On an existing jupyterhub/jupyterlab install this functionality works fine. It downloads directly to my local download folder.

I recently setup a TLJH install on a new server. When I try to download the same .html file (or any html file for that matter), it opens the file in a new browser tab instead of downloading it. It also seems to try to do this with other file extensions and then downloads them normally, but it does flash open a new tab briefly before downloading. The older install does not exhibit that same flash of a new tab for other files types.

I'm using Chrome as the browser.

Old jupyterhub/jupyterlab setup where download works:
jupyterhub version: 0.8.1
jupyterlab version: 0.35.4
notebook version: 5.4.1
Installed manually

New jupyterhub/jupyterlab setup where download does not work:
jupyterhub version: 1.0
jupyterlab version: 0.35.4
notebook version: 5.7.8
Installed with TLJH installer

I'm unsure if this is a jupyterlab issue, something with TLJH install, or something else entirely.

why you close this? @kevmk04
how to fix it?

[kevmk04]

@wqh17101 I closed the issue because the problem is actually a jupyterlab problem not a hub problem. I have an open issue in the jupyterlab GitHub for this problem.

@kevmk04 all right

@wqh17101 Release 1.0.5 of JupyterLab resolves this issue.
