Win10 and Firefox

[F2d5thCav]

I've been having issues with my laptop (Win10) suddenly having 100% load on the hard disk drive.  (As reported by Task Manager).

Tracked it down to Firefox.

Firefox doesn't do behave that way all the time, but there are instances where it somehow loads the drive access and really slows down the entire computer.

FYI for those who use Firefox.

If anyone knows of a good, secure browser that isn't a microsoft or google product, please advise.

Thanks and Cheers
