Why do I get Mozilla Firefox not responding when I have Adobe Flash Player

Up until both Adobe and Mozilla Firefox updated I had full use of my computer. Now, with with both Mozilla Firefox and Adobe Flash player I get the response "Mozilla Firefox not responding" I have eliminated all my plug ins and the computer is just fine until I enable Adobe Flash Player.

Some added toolbar and anti-virus add-ons are known to cause
Firefox issues. '''Disable All of them.'''
Open the options of your anti-virus, and tell it to leave the browsers alone.
Start '''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Firefox in Safe Mode]''' {web Link} by holding down the '''<Shift> ''(Mac Options)'' ''' key, and then starting Firefox. Is the problem still there?

Regularly get Mozilla Firefox (Not responding) message

After leaving computer idle but logged in to our website back pages when I return and try to click in I get the message Mozilla Firefox (Not Responding) this tends to happen more in the afternoon. Sometimes the only way to clear it is to turn the computer off.
Why does this keep happening?
Do I need a different browser of is it the age of my computer Dell Inspiron 1100 approx. 4 years onld.

'''Try the Firefox SafeMode''' to see how it works there. 
''A troubleshooting mode, which disables most Add-ons.'' 
''(If you're not using it, switch to the Default Theme.)''
* You can open the Firefox 4.0+ SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. 
''Don't select anything right now, just use "Continue in SafeMode."''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
'''''If it is good in the Firefox SafeMode''''', your problem is probably caused by an extension, and you need to figure out which one.

System running slowly and keeps locking up. I get "Mozilla Firefox not responding" message until system catches up and strts operating again. Ideas?

When I boot system it takes forever to open. Once it is up and running I can move through some pages easily but if I try to open news sites or sites with a lot of information the system locks up as it is loading (sometimes for several minutes at a time) and will not let me get out until the system catches up. In some instances I get a "Mozilla Firefox not responding" message in the upper tool bar and the screen gets a milky color until the system catches up and allows me to continue. Any ideas?

According to everymac.com, your Mac came with Tiger, 10.4.x and can't go any higher than Lion, 10.7.x.
It would have come with gray, machine specific disks. Since there's no reason to install 10.4.x first, and then Snow Leopard over that, just purchase a retail copy of Snow Leopard for $20. What you won't get with the retail version of SL is the iLife suite (Garage Band, iDVD, etc.) that were on the original bundled disks, but you can purchase iLife on Amazon pretty cheap, and get newer versions besides.
When you get Snow Leopard, you can boot to the DVD, erase the drive and install everything clean. Hopefully, you issue is only software, and not hardware related.

Keep getting Mozilla Firefox (not responding) arrow takes 40 sec. to move same with scrolling....tried safe mode...still not working

zzxc suggested safe mode....tried it but still get the same not responding and SLOW arrow commands...loading circle showing before moving arrow.
== This happened ==
Every time Firefox opened
== a week or so

me too !
but it only started happening just after the latest update,
and of course firefox can not expect people to remove their security, windows defender nor firewalls in order to use their products - that's silly.
so now,when i finally get frustrated, i have to use chrome or IE
... actually it just happened right now so I am off to chrome
hooroo

Every since the June 22 security update, I get Mozilla Firefox (not responding) at any page I go to. Have to sit and wait several minutes for it to load each page. Getting all kinds of errors in arsing values. Declartion dropped. Etc.

Just a few of the types of errors collected.
It is getting to be a pain to have to sit and wait until it is responding again. At that point the cursor is locked on to what ever it is sitting over. You have to click on it to release it.
Anyone have any ideas.

Glad it is fixed. Thanks for posting back, (even if we are not sure exactly what happened).

I get many Mozilla Firefox Not Responding messages I have the 4.0 what do I do to correct this irritation I need step by step HELP!!! Done what little I know how to do. Thanks

It locks up where I can do nothing except wait and wait for response. I get end program messages, it loads slow when initializing. I have run AVG, Windows Defender, defragged etc. I am not that computer savvy to figure this out. Need assistance from one of you experienced users out there. Sometimes it runs fairly smooth, BUT THEN!!!!!! Thanks!! PS Is this considered CRASHING???

hello Guido077, does it make a difference when you keep the real plugins disabled under ''firefox > addons >plugins''?
please also [https://www.mozilla.org/firefox/update/ update firefox to the latest version] as soon as possible and keep your [https://www.mozilla.org/en-US/plugincheck/ plugins on the latest level] too...

Mozilla Firefox (not responding) Why does this keep happing? It keeps timing out on anything I do its so fustrating

I could be on a website or visiting a any webpage or just enjoy different sites on firefox and all of a sudden it stops me form doing any. it says Mozilla firefox (not responding) and I have to wait and then it comes back on its happens a great deal

What worked for me instantly today after several days of pain: I cleared all my history.

Repeatedly get this message and have this happen - mozilla firefox not responding - and then everything is frozen. why and how can this be prevented?n. g

repeatedly get the above message - mozilla firefox not responding - happens on no particular website - often happens on my aol home page. i would like a simple, easy to understand explanation or solution.
also, often get this message - Problem Loading Page. problem appears to be with firefox as i can access the sites through my mobile device.
and one other problem - a site i could accesss but was not allowed to register - after thinking i must be out of my mind going round and round in circles - i called the site's 800 number and was told there is always a problem registering using mozilla firefox. so what did i do, i registered on my mobile.
i don't think any of this should be happening.
please help and/or advise. thanks.

Many, many times in a session, I get this: Mozilla Firefox (Not Responding). Frustration is setting in when I have to kill the computer, and start all over again. Anger is beginning a slow burn, too.

Since the latest version (don't even ask me) was downloaded and installed, many times in a session when I am browsing the net, or opening a text document or a spreadsheet, flipping back and forth, I'll have to stop and sit for an indeterminate amount of time because up on the header, I'll get the message Mozilla Firefox (Not Responding). When looking down toward the front of the laptop, I note the hard drive is going full bore, whole hog, whatever you want to call it. Sometimes after repeated hitting the "enter" key, the program will catch up, and begin functioning again. Other times, because the program is stuck, the laptop will overheat, causing me to manually shut down, wait a while while the hard drive cools, then restarting. When I have to manually kill the session, I cannot, repeat CANNOT get the machine shutdown programs to work.
What the hell is wrong with Firefox with this crap?

Hello jesterabk, '''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Once you get the pop-up, just select "'Start in Safe Mode"''
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
Thank you.

Mozilla firefox (not responding) 27

I have recently changed to mozilla firefox 27. to update my windows 7 vista and constantly it keeps freezing and saying not responding and i have to wait to carry on, I am not great on computers and need help as simple as possible so i understand please someone help.

I have same. Vista 7 and er...sometimes Firefox.
I have the latest Firefox installed hoping that it wold stop that
Mozilla Firefox (not responding) cropping up...
My mistake. Since up(lol)grading to the latest that error is almost permanantly etched into my screen. It is DREADFUL.
Even at launch I can get that message.
I can NEVER get past 35-40 mins before it will crop up and hang the PC.
I get that and its oft companion "Plug in busy stopping you having fun" etc
I have written to Mozilla twice3 (only to be ignored) that this is not OUR error, but THEIRS. Basically your browser falls over.
As for solutions - sorry - I will not be fobbed off with FAQs (which never cover one's particular prob) and the "solution" of "Oh, just RESET Firefox" does NOT work. It won't work because all I am doing is rebooting a faulty browser.
So whilst having to go back to IE will Firefox be actually FIXING their software so that the NEXT upgrade can actually SUSTAIN a browsing session that could ooo maybe go over an hour?
Currently I have the Task Manager open permanantly so as to flag "END TASK" next to "firefox is not running...."

Mozilla Firefox (Not Responding)

http://www.mozilla.org/en-US/plugincheck/?
go here and it will check if your plug ins are up to date...If they aren't, it will give you a direct link on how to update them. It will most likely be your shockwave player that you have to update. If this was your problem, it will stop the freezing/not responding problem.

Mozilla Firefox (not responding) happens every 9 minutes.

In Windows 7, every 9 minutes Firefox hangs for about a minute with the message "Mozilla Firefox (not responding)". After about a minute it will work just fine. It happens on all webs sites.
I've tried various things to no avail. (Disabled add-ons, etc.) I'm not even sure it's Firefox. I have a feeling it's some program checking for updates or something every nine minutes.
Does anyone have a clue what runs every 9 minutes?
