I'm not having any problems with any other sites, just our class website.

CC does not require Java - just javascript (not the same thing) that is already built into browser. So the key was the Flash.

FYI: It's recommended (for security) to disable java in plugins (ask to active). You can research this for why.

Haven't met a website in the last 5 years that required it.

I just checked your site in Firefox and had no issues. Have you tried from any other devices? Have you cleared your cache and history to see if that help? Have you loaded any new software / toolbars lately that might be causing the issue? Sorry these suggestions are random, but I don't have any idea since I can get there on my end.

I can get in there, Scott, but when I tried to navigate around the site it stopped responding. This computer is the only device I use to access the site. I will see how it does now and report back if the issue persists.

IE and Chrome work fine.

THanks

I'm seeing the same symptoms, at other web sites as well, and they started when FireFox updated to 41.0. Task manager shows FF's Plug-in-Container task hanging and taking 100% of one processor core. You can resolve the problem when it happens by opening Task Manager and ending the Plug-in-Container task.
Hoping that there will be a 41.0.1 coming quickly.

Make sure your Flash is up-to-date. If you have a bunch of "old" flash showing in addons, you have to manually delete them from the macromedia/flash directory. Current version is 19.0.0.185 (I was on 19 and just updated .. maybe that's a problem now )

P.S. plug-in-container only shows in task manager if there's a plugin active. And that's typically Flash for CC and a lot of other sites.

Joe, what version of FF are you using? That was a known issue with older versions.

(Your posts have been from Chrome, not FF)

Jack, I'm using Firefox version 41.0

Did you follow what Scott suggested? FF has an issue keeping old data around. It will often not load new versions (images, scripts, etc) unless I clear cache (Tools, Options, Advanced).

I've not had anything odd (yet) with 41 nor prior/latest Flash. If it persists, you can try disabling add-ons and then put them back to isolate. Or could be some other peripheral pgm here.

Can be a frustrating puzzle at times

Had enough of this. I went back to an older version.

Let us know if that keeps working. Pretty odd. So far, nothing yet here. But I do not use ANY flash, except the CC messenger stuff.

No issues with the older version (39.0).

Except you just posted using FF 40 (it was 39 last time though).

The last post was from work.

This annoying problem appears to have been resolved in FireFox 41.0.1 which was released today.
