Freshly installed Firefox runs very slow and stucks often

Hi, so I thought I should try and install FireFox. But I noticed that it's super slow although I just installed it. All Add-Ons I'm using are PrivacyBadger, EnhandedYouTube and AdBlock. Disabling any did not fix my issue. I often encounter super long loading times or FF freezes for a couple of seconds. RAM and CPU usage are ok, 200mb RAM and +-5% CPU. Doesn't matter if a game is running or not, it's always the same with the "lags" and long loading times. In between it's super fast for a brief moment but then it's slow again. Since I'm no expert I have no real idea what could cause the issue, so if you need any more info just ask and I try to provide it.

Oh and I forgot to add: whenever I open a YT Video and change tab, it plays not even 1 second and then automatically pauses.

Try to uninstall Adblock Plus and use uBlock Origin instead. Adblock Plus has been reported to cause issues like you reported.

Well thanks, the slow performance issue is resolved, but the video thing is still there. Any idea on that?

When multi-process windows in Firefox is enabled then Firefox will use more memory and may be less responsive.

You can try to modify multi-process settings to see if this has effect.

  • set dom.ipc.processCount to 1 if it is currently set to a higher value (4)
  • disable multi-process windows in Firefox

You can disable multi-process windows in Firefox by setting these prefs to false on the about:config page.

  • browser.tabs.remote.autostart = false
  • browser.tabs.remote.autostart.2 = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
