Mozilla works too slow when many tabs (~50) are opened.
Hello, my Mozilla Firefox is hanging when I have about 50 tabs opened. So I have to kill the browser and restart it. After a few hours of work I have to do that again. Any ideas/suggestions?

Having more that 50 tabs shouldn't be a problem.
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 or userChrome.css 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
@cor-el thanks. Did not help. After one hour of browsing the same problem occured
Just curious, but what are the specs of your computer? Could you also include a screenshot from the task manager showing the performance when you have the 50 tabs open?
@ jonzn4SUSE jonzn4SUSE Hope this would be enough, I will also send my memory/cpu usage when it stuck again (just killed and restarted it)
btw google chrome works fine even if I browse 100 tabs
You can check the Firefox Task Manager (about:performance) and about:memory pages.
