My firefox started to get really sluggish, crashing sometimes and CPU usage was way too high. It was at 30-55% the last time I checked. I have a Thinkpad T450s, so there shouldn't be any issues with performance and resources. The T450s got an i7, 12GB RAM and a 512GB SSD. I just uninstalled Firefox, downloaded the newest version and installed it. The first thing to greet me were my old tabs. Everything was like nothing happened! Every bookmark, the history and all cookies are still present. What happened?
21The easiest way to 'speed it up' a bit would be to navigate to
about:support
and click theRefresh Firefox
button up the top right. – Bob – 2017-03-28T00:29:38.293I definitely concur with @Bob's good advice. Although I rarely encounter any issues with Firefox either at work or at home, the built-in Refresh Firefox capability always seems to alleviate any lingering problems.

The Refresh option always works for me, although I also had speed improvements by using SpeedyFox, which is less drastic and just optimizes the profile database.
– r41n – 2017-03-28T13:47:28.623"Refresh Firefox" seems badly named. It should be "Reset Firefox". – JAB – 2017-03-28T17:28:57.567
1I've been using Firefox since before it was called Firefox and I never saw this option. Cool. – Joe – 2017-04-04T02:50:04.850
