Firefox For Mac Force Refresh

I'm trying to update OS X, and haven't been able to Force Quit Firefox.It doesn't show up in the Force Quit dialog box, or in Activity Monitor. I've tried Killall in Terminal (killall -9 firefox-bin), and Terminal tells me there are no matching processes to be found. But when I try to restart my (mid-2015) Macbook to update, it tells me Firefox is preventing me from shutting down. I've tried to start Firefox from Finder and from the dock, and nothing happens, not even in Safe mode. Can someone please help?

Sorry I can't help, but yes, I'm having the same problem. Seems to have appeared since Firefox 41 came out (I'm running on OS X 10.11). Like you, I find it's just freezing up, but unable to Force Quit it, and it doesn't show up in any process lists, and it can't be relaunched either. I managed to clear it from the Dock, by using 'sudo killall launchservicesd', and then 'sudo killall Dock' in Terminal, but that gives varying degrees of 'fix'. Sometimes it's OK, and I can continue as normal, but often it still leaves something active that even prevents a restart/shutdown, and I have to use a hard (power button) shutdown. For now I have deleted all Firefox Mozilla stuff from my system. Hmm, interesting.

Safari on the Mac Step 1 First click on Safari and then click on Empty cache. Step 2 Click on the Empty button Stap 3 Click on the refresh icon Force Refresh Safari. Usually a 'force refresh' is enough.

I hadn't had this with anything else yet. However, I have found another little anomaly which might be a little pointer. I have been a user of BookMacster for some time, but have recently found it not running. After a bit more testing, I found that it had trouble because of Firefox's inability to open and close cleanly in the Dock (It's not just BookMacster though, it does this if you restart Firefox after changing and extension or installing an update). I deleted Firefox and gave Chrome a try instead, now that isn't having the same trouble, in that it gets stuck in the Dock, but it won't allow BookMacster to open and close it cleanly to run its extensions, and gives pretty much the same end result as Firefox does.

May be nothing in that, but you never know. The strange thing is that everything else is fine, it just seems to be these web browsers. The Firefox update goes fine and in fact, Firefox works fine. It's only when I Try to close Firefox or shut down (I usually close all apps before shutting down) that I have the problem. I have had a similar problem with Adobe CC Desktop and that was due to 2 copies (Old and New) of the App being in the system.

After the restart, the old Adobe app got cleaned up and everything worked fine. That is sort of like what is happening with Firefox. Once the system restarts clean with the updated Firefox, everything seems to work fine until the next update and then it has that hiccup on on the first program restart. Having said that, I am going to see if I can change the update setting from 'Automatic' to 'Notify me of Updates'. Then I can shut down FF, install the downloaded update and I don't have to worry about residual / conflicting program data being resident in memory when FF restarts. I have had the problem for some months. As discussed in the bugzilla link, at first I thought it was a one-time glitch which would clear up with the next release from either Apple or Firefox.

I am running OSX 10.11.4 and Firefox 45.0.2. In all I have 3 iMacs and 2 Macbook Pros in the house. It only seems to occur on my main iMac, even though all are up to date. My main iMac is mainly distinguished by having a 3Tb Fusion drive which caused a lot of problems back in the day. Lately Firefox has started quitting unexpectedly when I close one of the tabs.

Seems to be a random event so difficult to reproduce. But when it crashes I have the same problem of not being able to restart Firefox or shutdown the Mac -- again, not every time. Vmware vsphere client 5.1 for mac os x. As someone said, it is a very annoying bug.
