Hiya. Since I upgraded to Firefox 36 my MacBook Air battery has been draining horrendously quickly. Is there anything I can do to fix this?
Since I upgraded to Firefox 36 a few days ago my MacBook Air's battery has been draining at a horrendous rate when I've got Firefox open. For instance, just now when I'd not got Firefox open, my activity monitor told me I've got two hours usage, but as soon as I opened Firefox (even with not having a window open) my usage was instantly downgraded to about 50 minutes. I'm having to recharge the lappy every four hours, which is ridiculous - and wasn't happening until I installed the upgrade.
On top of that, since I installed the upgrade, Firefox has crashed at least once a day, which hasn't happened at all in the nine months I've had this MacBook Air.
This isn't like you guys! What's happened?

Hi Cathy, it is mysterious why Firefox is so busy. Often Firefox has cache maintenance and other tasks that make a lot of disk accesses, but they shouldn't run continuously.
Could you try operating Firefox in its Safe Mode for a while to see whether that makes any difference? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: Troubleshoot Firefox issues using Safe Mode.
You can restart Firefox in Safe Mode using either:
- "3-bar" menu button > "?" button > Restart with Add-ons Disabled
- Help menu > Restart with Add-ons Disabled
Not all add-ons are disabled: Flash and other plugins still run
After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (not Reset).
Thank you jscher. It seems to have sorted itself out in the meantime, but I'll keep your suggested fixes in case it happens again.
Being a bit of a Luddite, though, what is "3-bar" menu button > "?" button >?
Hi Cathy, I'm thinking of the button at the right end of the main toolbar with has 3 horizontal lines. Some people call it the hamburger. It calls up the graphical menu.
Thank you so much. I did that, now what do I do to get my toolbar items back?
Hmm, I'm not sure what you mean. What did you do exactly?
