Try to disable multi-process tabs in Firefox. You can disable multi-process tabs in Firefox by setting the related 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.
You can inspect the about:memory page to see what takes up most of this memory usage.
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 -> Appearance
- Do NOT click the "Refresh Firefox" button on the Safe Mode start window
