Blue Ball just under the cursor is spinning for no reason when using Facebook (not the app). Is there a fix for this? Seems to only happen when resting. If cursor is on a link then the cursor returns to normal.

Same here. With Mountain Lion. Only with facebook and Firefox.

I have had this issue for the last 3 days as well.

Firefox 39.0

Yosemite 10.10.4

I upgraded from Mavericks late last night and it still didn't change it. Was kind of hoping my planned upgrade to the OS would fix this thing.

I need to go out for a few hours today and my last ditch to fix this will be to force an IP change, but from the posts in this thread, I don't think that's going to fix anything. My belief is it's a Firefox issue since it only started happening on the last update to FF. Facebook has always had script issues for me because they have so much crap running in the background and their trackers embedded into everyone elses cookies on your browser from other sites you visit I'm not surprised Firefox is ******** about this. JMO

I'll report back when I find out if the IP change fixes things.

EDIT TO ADD:

I just found this on the Firefox support area: https://support.mozilla.org/en-US/questions/1070199

No answers yet but if you give them an email after clicking "i have this issue too" you will get an email of any fixes or answers to the question.

Just tried the update in Firefox and it didn't make a difference. 😕

I updated Firefox and so far the problem has been fixed.

What version of FF are you using now?

I am using Version 39.0 of Firefox.

yes, I updated to FF 39.0 and that fixed it. Thanks!

Whoops--I spoke to soon. It's BAAACK!

I spoke too soon too. It's back. 😠

That's why I asked what version. I've the same one and it's still there.

I'm pretty sure it's a Firefox issue. see the link to the FF discussion on their site.

Just for grins I switched to Safari browser on my iMac, logged into Facebook, and no spinning blue ball!

So, I switched back to Firefox, logged into Facebook, and ... no spinning ball there either.

Hmmmmm...

It's back!

I have this issue, too. And it started a few days ago. I'm running 10.6.8 and using Firefox 39.0. I tried loging out of Facebook and shuting down. Rebooted, logged in. No joy.

I switch between FF and Safari and there's no problem on Safari. Maybe FF thinks it's an enhancement. 😉

OS 10.9.5
FF 39.0

Suffering from spinning blue ball(s). Yes...VERY annoying.
