I don't know how to better file this bug, guidance would be appreciated.

After very little time, Firefox (Nightly, but I also experience this using Release) becomes barely usable for me, on my 3-year old i7 Dell XPS12 with 8gb memory and 256gb SSD, running Windows 10. By barely-usable, I mean it starts taking up about 75% of CPU (actually hovering between 50 and 90) and there are often long UI hitches. Watching videos and generally doing anything becomes painful.

My work-load is 6 pinned tabs of GMail, Facebook, Tweetdeck, GoDaddy mail, WhatsApp and IRCCloud. I then have an additional few tabs open that are usually short-lived. In the attached profile, I have 1 active tabs open,

I use LastPass (4.x) and uBlock Origin.

Attached is a profile taken while my browser is in this state - I'm doing nothing at this point, with the Facebook tab visible.

For the record, all other major browsers handle this workload more admirably, with the same add-ons.

I believe we should just close this out, as this bug was filed 6 months ago and nightly is in a very different state at the moment. Chris: If you can reproduce this using the latest 56 nightly, please feel to reopen and I will find someone to take a look at your profile. Thanks for filing it.
