I was trying to use Firefox in at least 20 minutes or so, but then something went wrong. The CPU usage was going high to 90% to 100% after usage. I'm using the dual core processor (Intel Pentium Dual Core @2.00 GHz) and my PC was super slow. And I'm too scared what's going to happen, so I immediately restart my computer and everything was back to normal without opening Firefox. It happened last night (yesterday at 9:00 PM Greenwich Mean Time +6:30) Is this an issue or is that a bug? I wanted to get this fixed. Thank you!

Best regards, Wai Min Soe

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

Start Firefox using Troubleshoot(Safe) Mode {web link}

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