Since I installed Ubuntu (fresh install on a new machine), and set Google Chrome as default browser, whenever I open links from external apps these are open as blank tabs in new browser window (no actual redirection to site, just a blank tab).
I switched to Firefox and this behavior doesn't persist. If I switch back to Chrome as default browser (via default apps) it happens again.
I noticed that both in Unity Launcher and from the default app settings, Chrome isn't called just 'Google Chome' but 'New Tab - Google Chrome'. Not sure if this is related or how to fix it. I made some searches that suggest to look for mimeapps.list or check that the google-chrome-stable.desktop contains a %U value, but none of these helped.
This is an extract of the .desktop entry by the way:
this is mimeapps.list
