Firefox is slow to load and view pages and repeated "Firefox is not responding" message

Firefox is quite slow to load and view pages with and I keep getting the "Firefox is not responding" message.
I have the latest version, plus the latest Adobe Flash Player, Shockwave Player, etc.

Note that Firefox 36 has been released officially.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to install for Firefox and the plugin-container process and the updater process.

is this normal, and how do i fix it?

can you try restarting Firefox in safe mode.

When loading ANY web page, it take firefox 3sec to load a blank page. No matter what website I try to load, it just loads a blank page

When loading ANY web page, it take firefox 3sec to load a blank page. I have tried everything, starting firefox in safe mode and dissabling all add ons, turning 6v on and off, turnig proxy on and off, reinstalling firefox, restarting my computer, and reinstalling drivers. I can use another browser to surf the internet but finding one that is as capable to firefox isn't easy.
ps. Firefox did start at one point and then just stoped.
I use Linux Ubuntu 11.04 single boot

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Is there a quick way to view pages in Safari, Firefox, Opera (not Live Preview)?

Is there a quick way to view pages in Safari, Firefox, Opera (not Live Preview)?

Currently, no, but we have an item in our backlog to research this.

Just bought a Macbook air. Isn't it supposed to come loaded with Numbers, Pages and other basic software?

Just bought a MacBook Air. Isn't is supposed to come loaded with Numbers, Pages and other basic software? I can't find these. Can anyone help?

It comes with iPhoto, iMovie and GarageBand, but not with Pages, Numbers and Keynote. You have to download them from the Mac App Store.
Open the Mac App Store, go to Purchases and accept all these apps, so they will be downloaded and installed free of charge.
If you cannot download them, see > http://www.apple.com/creativity-apps/mac/up-to-date/

Flash slows FF with hangs and 'not responding' messages.

Shockwave flash is causing hangs giving 'firefox is not responding' message and slows my internet experience. I know its the flash add-on because when i disable it, firefox performs much better. I've tried all the suggestions concerning flash problems on this site and nothing has worked. I am running win 7 64 bit (home premium). plus Firefox 36.0.1. All drivers appear to be up to date but i will double check.
my question is.... is there a way to easily disable/enable flash w/o going into the add-ons manager? Depending on what i'm doing, i'm in add-ons manager to either enable it when i need it or to disable it when firefox is slow and hangs.
I've gotten to the point where i just open add-ons manager in a tab and leave it open because i know i'll probably be in there turning flash on or off depending on how its effecting my machine.
Also, i tried running flash in 'ask to activate' mode, but you have to reload the page so it can find the add-on.
This problem has been ongoing for a couple of months now; Firefox performance used to be so much better but this problem doesn't seem to be getting resolved. I like firefox, I really don't want to go to another browser.
Thanks,
Duke

Hi Duke, your bookmarks and other Firefox data actually are in the C:\Users folder so it's safe to delete the folder under C:\Program Files (or C:\Program Files (x86) on 64-bit systems).
When you run the installer again, it should detect and use your previous settings folder. To get a clean start on that as well, you can:
'''Create a new Firefox profile'''
A new profile will have your system-installed plugins (e.g., Flash) and extensions (e.g., security suite toolbars), but no themes, other extensions, or other customizations. It also should come with completely fresh settings databases and a fresh cache folder.
''This does not replace your existing setup; the new folder exists in parallel with your current settings.''
Exit Firefox and start up in the Profile Manager using Start > search box (or Run):
firefox.exe -P
''Don't delete anything here.''
Any time you want to switch profiles, exit Firefox and return to this dialog.
Click the Create Profile button, assign a name like March29, and ignore the option to change the folder location. Then start Firefox in the new profile you created.
Does that work any better?
Note: When returning to the Profile Manager to switch back to your normal profile, you might be tempted to use the Delete Profile button. But... it's a bit too easy to accidentally delete your "real" profile, so I recommend resisting the temptation. If you do want to clean up later, I suggest making a backup of all your profiles first in case something were to go wrong.

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.

I am getting "Not Responding" message. The fix in the Help is confusing and doesn't seem to match my setup. Using Windows 7 & firefox 7.0.1

The problem started after last update. I tried following the directions in firefox Help without success. They were confusing and the instructions did not match what I was seeing on my screen. I need a simple quick fix thank you.

There could be more than one reason for such messages.
There is a problem sometimes with the database file used for history and bookmarks see
* http://blog.bonardo.net/2011/09/30/is-your-firefor-freezing-at-regular-intervals
There was a change made which seems to affect some Windows users, and has a workaround, but tends to result in images etc not loading rather than a not responding message see
* [[firefox never finishes loading certain websites#w_lower-the-max-number-of-http-connections]]_lower-the-max-number-of-http-connections
Are you getting any other error messages, or indications of problems ?
* not directly related to an update but also see [[firefox hangs]]
* and [[Firefox is already running but is not responding]]
P.S. I note you have BrowserPlus, that has sometimes, recently, been associated with firefox problems, it would certainly be worth trying temporarily disabling that.

Mozilla hangs (not responding)message. I have loaded the latest version and still have the same problem, why?

Firefox hangs (not Responding message) I tried refreshing Firefox. I tried deleting history. I deleted Firefox and reinstalled the latest version which I already had running before and the same problem occurs. It starts hanging after a few minute when I start the computer mostly on my email page or ebay page and continues to hang for about 5 to 10 minutes then it starts to function normally. It is most annoying and I cannot figure what is causing the problem? Please help if you can?
Thank you,

Hello Fred McD,
If I was unclear I am sorry, I can not start Firefox normally after starting the computer in safe mode with or without the network because my USB internet modem will not allow me access to the internet in the safe mode. the USB modem will not work when the computer is in safe mode. The only thing I can do is start the computer normally then enter Firefox in the safe mode by holding down the shift key and pressing the icon for Foxfire at the same time. This will put Foxfire in the safe mode but the computer is operating in the normal mode Because I can not get access to the internet when I use the computer in the safe mode The USB modem will not connect to the internet when the computer is in the safe mode.
Thank you,
aleggert

I have a Windows Vista desktop and an old XP laptop, both run Firefox perfectly. However, my Toshiba Satellite T135 laptop will not run ANY version of Firefox--constant "not responding" messages. Chrome and IE9 work perfectly. Help!!

To mostly repeat my question, I am a longtime Firefox user on both an XP laptop and a Vista desktop. So here I get the most "capable" computer of all, a Toshiba Satellite T135 laptop, 64-bit Windows 7, 4G RAM...and it won't run Firefox at all! I have installed an uninstalled both Firefox 3, and just now, Firefox 4. No changes. When I open the software, it usually just locks up for a minute or so, and I finally get a "not responding" message at the top of the screen.
Obviously there is something corrupt in the guts of my laptop. But both IE9 and Chrome work very well--Chrome is blazing fast. I still prefer Firefox because it works best with some particular software I use for work...but I have to go to one of my older computers to do it!
ANY solutions out there? This seems like a very odd problem.
Posting from the Firefox website...using Google Chrome!

I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

HT4623 The update to iOS 7 is frozen at the Terms and Conditions page and will not move no matter what I click on. I cannot access my iPad as it is frozen on this screen.

The update to iOS 7 is frozen at the Terms and Conditions page and will not move, no matter what I click on. I cannot access my iPad as it is frozen on this screen. How do I remedy this nightmare?

Reset the device:
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
Then try updating the software again.
If that doesn't help, tap Settings > General > Reset > Reset All Settings
No data is lost due to a reset.

My Firefox won't quit and gives a "not responding" message after I use Google Mail. I have tried starting in "safe" mode and the problem still occurs.

I have an issue where Firefox wont' quit and gives a "not responding" message after I have been using Google Mail. It works fine when I am not using that program. I have tried Safe Mode and the problem still happens when I go to Google Mail, so it is not connected with add-ons, extensions, etc.

Many site issues can be caused by corrupt cookies or cache. 
Clear the Cache 
'''''Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"'''''
 and 
Remove Cookies '''''Firefox/Tools > Options > Privacy.''''' 
Under '''History''', select Firefox will '''Use Custom Settings'''. 
There is a button on the right side called '''Show Cookies'''. 
If there is still a problem,
'''''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]'''''
 While you are in safe mode; '''''Firefox Options > Advanced > General'''''. 
Look for and turn off '''Use Hardware Acceleration'''. 
Poke around safe web sites and see if there is still a problem. Then restart.

Keep getting "not responding" message, extremely slow, have tried rebuilding data base, tried removing and re-installing. Still the same

Do you use McAfee anti-virus software?
If yes, please read:
* https://wiki.mozilla.org/Thunderbird:Testing:Antivirus_Related_Performance_Issues#McAfee
Is this an Imap mail account?
if yes, you can choose to only synchronize the most recent of emails instead of a whole folder.
see info :
* https://support.mozilla.org/en-US/kb/imap-synchronization#w_configuring-synchronization-and-disk-space-usage
Make sure you compact folders on a regular basis to remove all 'marked as deleted' emails.
Tools -> Account Settings -> Server Settings -> Clean up ("Expunge") Inbox on Exit will compact the Inbox folder when you exit Thunderbird. If you check "Empty Trash on Exit" it will also empty and compact the Trash folder when you exit.

How do I make Firefox stop crashing and giving "not responding" messages. I don't want to reset it because I've got lots of extensions. Other browsers work fine

Every few minutes it gives me a "not responding" message and/or it crashes. I've checked all my add-ons, they're all updated. I've tried accessing the same websites that crash on Firefox with other browsers and it works really well. I don't want to reset it as one of the troubleshooting solutions suggest because I'd rather change to another browser than having to re-install all my add-ons. Please, is there anything that can be done to fix this?

Hello,
'''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.''
Also try to disable hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.
