Cannot open PDF file in Jupyter Notebook (Chrome)

Question

I usually run my Jupyter Notebook on Chrome and can directly open PDF files by clicking on the file name.

However after updating my Google Chrome browser, I noticed that I cannot open my PDF files using Jupyter Notebook anymore, and I get error message:

localhost is blocked
Requests to the server have been blocked by an extension.
Try disabling your extensions.
ERR_BLOCKED_BY_CLIENT

I have removed all extensions, browsing data, cookies etc. in my Chrome browser but the error still exists.

I have reinstalled my Chrome and my Anaconda several times.

I tried to debug this issue by using the inspect function by right clicking on the error page, and get 304 Not Modified

I am not sure if it is something wrong with my chrome://flags/, and I have reset all to default.

I also tried Notebook in Microsoft Edge and Mozilla Firefox, all works fine with PDFs.

However, when I rollback my Chrome version, Chrome+Jupyter is able to open PDF files.

Finally, I can simply opening a PDF file using Chrome without using Jupyter Notebook. Still, I wish to figure out why I can't open it in Jupyter anymore.

My Chrome version is: Version 88.0.4324.146 (Official Build) (64-bit)

My solution to this is that you should try to open it with jupyterLab. It works fine even in chrome.
