New tab does not work after 14-15 tabs.
Recently, if I have 14-15 tabs open, attempting to open a new tab using the new tab button, ctrl-t, or choosing to open a link in a new tab does not open any tabs. Choosing the add-ins menu, the preferences menu or the like from the hamburger menu still opens a new tab as normal even when the new tab functions are no longer working for browsing.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Safe Mode start window

Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.

Apparently restarting in safe mode fixed the issue permanently even after switching back to normal mode with the same addons and extensions still installed and activated.
