Firefox freezes when attempting to interact with a page.

Whenever I start up Firefox (4beta7 portable) it acts normally. I can visit web sites without a problem. However as soon as I click on any page (including about: pages) it freezes forever. I have to use Windows to manually close it with the program is not responding box. I have a feeling that it might be related to one of the plugins I installed immediately before restarting

Firefox freezes when I access my add-ons page.

Firefox freezes when I access my add-ons page. I must use Task Manager to unfreeze it. Some add-ons (AdBlock) still work. Others (NetVideoHunter) don't. I would like to remove all the add-ons and start fresh, see if it makes a difference, but when I access my add-ons page to press the "Remove" button, FireFox freezes--so what am I supposed to do? I like Firefox because it's simple and generally glitch-free--until now.

hey furdeal - if you'd like a fresh start, you can simply [[Reset Firefox – easily fix most problems|reset firefox]]. this will keep your bookmarks, passwords & history but will remove all extensions and custom preferences...

Firefox freezes when opening a window with PDF files, etc., yet it works perfectly when using explorer as browser.

I think Firefox mozilla is having issues with Adobe reader. It frequently crashes. I think this may be why my computer freezes when pulling up a PDF file or other text windows, yet, everything works perfect when using Explorer as my browser. It is so frustrating using Mozilla because it gets stuck when opening windows which require pulling up certain types of texts or applications, then I have to wait forever, or, reboot, and once in a while it gets so stuck that I have to take out battery and remove all power sources then start from scratch, and set my computer back to all settings previous to failure. Like I said, this only happens with Mozilla, all other browsers work perfectly well, but I love my Mozilla and it is my preferred browser. Please help. Thanks so much,
susan

Hi Susan,
The Adobe plugin in Internet Explorer is a bit different from the one in Firefox, however they're all made by Adobe and they usually come with Adobe Reader.
When you open a PDF file in Firefox, it "calls" Adobe Reader to help it read the file. In this case, the Adobe Reader takes over, and it is responsible for freezing your browser.
I suggest you try the last 4 solutions presented on the [[Opening PDF files within Firefox]] (start with "Re-install the plugin" through "Re-install Adobe Reader").
Good Luck :D

Firefox freezes when going to a site or page that requires Flash Player, such as YouTube. I have the most updated version of Flash. Is there a solution to this problem?

I'm having trouble visiting sites or pages that require Flash Player, Firefox will just freeze when they're partially loaded and it will stay frozen until I close Firefox. This will happen with any page that uses flash player. I can disable it, but then I can't access the content which requires Flash Player, have to use a different browser and I'd rather just use Firefox.

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

Firefox freezes when i visit websites with videos on the background or i watch videos.I have windows 7 and the laatest version of mozilla.

I have windows 7 and the latest version of firefox.When i watch videos on youtube or visit websites with videos on the background mozilla freezes. I tried to disable all the extensions and plugins but it had no result.I didn't had this problem with versions of mozilla previous to 4.

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.

Firefox has trouble initiating, and when it finally does, every time I attempt to interact with the application it stops responding.

Firefox won’t initialize: I can open any program on my computer except for Firefox so it isn't that my computer is slow. It doesn't open at all no matter how long I wait. I've left the room and let the computer run before and it still wasn’t running when I came back. After a few clicks it finally it comes up, and I have to wait because I’ve clicked multiple times so of course it's going to open multiple times. When I'm online after successfully closing all but one Firefox window so that I don't crash my poor laptop, every time I attempt to interact with the program via clicking a link, opening a new tab, or typing something into the URL bar, the program freezes and goes into the not responding stage. Rarely, an unresponsive script message will pop up.

See:
* http://kb.mozillazine.org/Preferences_not_saved
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.

Firefox freezes when opening an adobe acrobat (PDF) file from any website

Firefox freezes when opening an adobe acrobat (PDF) file from any website. This only started happening after the latest update of Firefox was installed. Do you have a fix?

Firefox freezes when saving, printing, or otherwise opening "sub-windows"

Firefox freezes when I open a window to save, print, etc. - not always, but far too often. If I dare try to choose another folder in which to save, I'm even more likely to make it freeze.
When it happens for the first time after opening Firefox, I can often wait several minutes, then it unfreezes, and I can then do one or two more clicks (e.g., scroll, save, etc.) before it freezes again. Otherwise (or the next time, if I didn't restart Firefox in the meantime), the program just gets completely unresponsive, and I have to close it via the Task Manager. So there's unfortunately no error message, crash ID, etc.
Possibly related: When I'm using Firefox for a while (with many Firefox windows open), I'm often not getting menus displayed anymore, just the outline of the menus. The program still reacts to clicks into the outline, but it's like driving blindfolded... Menus include those from the menu bar, those from right-clicking into a website, or those from Adblock Plus (icon in the bar, at the right bottom of each window).
I'm currently still using 3.6.13 (with Adblock Plus) on a Windows 7 (x64) machine. The problem has persisted long before I've updated to this or previous Firefox versions... possibly since I've been using it on this computer (= summer 2010), but I'm not sure. I should add that I *am* using Firefox with lots (!) of Firefox windows open simultaneously, and I often let my computer hibernate rather than shut it down every single time I walk away... but I've been doing that for at least 5 years now (using tons of Firefox windows even much longer, still with Windows 95 or 98), and the problem is new. And limited to Firefox. (Indeed I can even open pages, on which Firefox has just crashed, in Internet Explorer or Opera, and then peacefully save, print, etc. there.)
I'd prefer to keep Firefox as my standard browser, but the problem is getting too annoying! Thanks for your help!!

Safari & FireFox freeze when I try to upload a file from my hard drive.

Safari & FireFox freeze when I try to upload a file from my hard drive. This just started happening in the past couple of days. I haven't installed any software, or made any updates (that I can remember.) When the browser freezes I can't "force quit" them. I have to manually shut the computer down are restart it. I would appreciate any help you can provide.

HI and welcome to Apple Discussions...
Safari and Firefox box.... it could be a problem with the hard drive itself, not your browsers.
Just to make sure, boot from your install disc, run Disk Utility to Verify and if necessary, Repair any errors Disk Utility reports.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
(In Mac OS X 10.4 or later, you must select your language first from the installer menu)
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*

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.)
* On Windows you can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
* On Mac you can open Firefox 4.0+ in Safe Mode by holding the option key while starting Firefox.
* On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
* 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 [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
Please report back soon.

HT1692 iOS7 Calendar freezing when attempting to accept/decline/maybe a meeting request from Microsoft Outlook Exchange... (iPhone 5s)

My iOS7 calendar on my iPhone 5s continually freezes when I attempt to accept/decline/maybe (respond in general) to any invitations that come through to the device... The main ones I get (so the ones I am experiencing the issue with) are from Microsoft Outlook Exchange Account (also synced through Mail app).
I have attempted to go via the emails I receive with the invitation and the device freezes when attempting to action the request through the Mail app also.
I'm hard reset the phone, I've removed and re-established the account in the phone, but nothing fixes the issue. It might work for one or two invitations, but it will start freezing again without a pattern...
This is a real pain, because these meeting requests etc are for work meetings and interviews!
Thanks guys!
<Edited by Host>

We are seeing a similuar issue here at work on serveral devices.
Using Lotus Notes for mail and calendar
iPhone 5 and iPhone 5S
Running iOS 7
When an email comes in for a meeting invite if you click on the Date and Time in blue it will walk you through opening the invite in your calendar and then I can Accept/Decline without issue. If you click on the Invitation icon, which seems to be what users intuitively, in the the email then it freezes up the mail app., see image below.

Safari for Windows crashes when trying to interact with bookmarks

Hello, I've installed Safari for Windows but when trying to interact with bookmarks, it crashes everytime.
Trying to view, create or import bookmarks all wield the same result: instant crash.
Can someone help ?
Thanks!

Just to try, I copied the en.lproj to es.lproj in every subfolder on Program Files/Safari, this because I have a Spanish (Mexico) regional setting, and after a Safari restart, bookmarks now works and even imported my info from IE and Firefox. This also worked me for other issues. More details in:

Firefox freezes when trying to open new Youtube Videos, what can I do?

I run Firefox 19.0.2 and the latest Flash plugin. All of a sudden Firefox freezes when I try to open Youtube videos. I can only kill it with ctrl+alt+del.
Note that I CAN watch Youtube videos that are saved as favorites and I also CAN watch videos I click as related videos. However whenever I use the search bar and click a new video I haven't watched before, Firefox will freeze over and over again.
I already tried disabling the hardware acceleration, as well as deleting the cache and varying cache size.
I also tried re-setting the dom.ipc config settings as stated here:
https://support.mozilla.org/de/questions/909133
So far, nothing would do the trick.
Your help is much appreciated, thanks a lot! :)

Thanks Cor-el!! It's over!
