Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Went into safe mode, Well, started at 200M and went to over 700M. with 5 tabs. Why in gods name does it need so much memory? That's ridiculous! Granted I'm running an older computer, ,but it's always been fine for web surfing and basic stuff, but now the cursor freezes constantly, and then I restart and it's just fine for about 5 minutes.

I think they need to get back to Firefox's roots. A simpler, better, faster browser. I remember when it first came out. It was blazing fast from IE, with a very small foot print. Now it's just another piece of bloat ware. Arrgh. Please fix it!

More than one process is normal for the current Firefox. http://www.ghacks.net/2016/07/22/multi-process-firefox/

Multi-process Firefox is codenamed "e10s". https://wiki.mozilla.org/Firefox/multiprocess


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

Type about:config<enter> in the address bar. If a warning screen comes up, press the Be Careful button. At the top of the screen is a search bar.
