downloadable font: kern: Too large subtable error with Osimis Viewer and FireFox Browser (Recommended Browser ?)

This does not seem to be a big problem, but kind of annoying. I have the regular version of the Osimis Viewer Installed, and I have an Orthanc server running on the web behind a proxy with an UBUNTU OS (Orthanc 1.7.x) , but also a local version running on localhost on the MacOS (Orthanc 1.5.7). In both configurations I’m getting the following errors in the console when using FireFox and viewing a study with the Osimis viewer.

Sample URL:

http://localhost:8042/osimis-viewer/app/index.html?study=79de0218-30258875-1adaa569-f71944db-a88eef7c

Errors in console:

Same errors using the proxy and FireFox. There do not appear to be errors in the console when using Chrome.

Just wondering if that is a known issue. Looks like it might be something related to FireFox itself.

Is Chrome the recommended browser for Explorer and the Osimis Viewer ?

Thanks.

This is just a warning from Firefox that does not prevent from using the Osimis Web viewer. The issue is tagged as “WONTFIX” in the link you posted (https://bugzilla.mozilla.org/show_bug.cgi?id=1185685), so this is unrelated to Orthanc and there is nothing we can do.
