I open many tabs on firefox, many times when I close the first tab, the entire window closes, and I have to reopen the browser. When I try that many times I get a message saying something like "Firefox is running Cannot open another window". When I checked the Task Manager I see firefox.exe and plugin-container.exe running. but the firefox is nowhere to be seen. Once I "End Task" these two, I can start firefox. This thing happens many times

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
