With jupyterlab-3 I don’t manage to open HTML or PDF file in my extension with openOrReveal.
The problem occur with firefox but not with google-chrome.
for HTML I tried:
this._docmanager.openOrReveal(path);
and
this._docmanager.openOrReveal(path, "HTML Viewer");
If the filepath is a notebook file: ok (With the first test of course)
If the filepath is an HTML or PDF file:
The page is refresh and the file is note open.
If anybody had an idea…
Regards
