Firefox 4 hangs when attempting to view the Applications tab in Preferences

Firefox 4 under MacOS X 10.6.6 hangs when I click to select the "Applications" tab on the Preferences dialog. It never paints the pane. When this happens, it consumes 60% CPU. Running dtruss against the running process shows a little activity, but not much.
I have tried deleting mimeTypes.rdf. It recreated a new, smaller one, but it made no difference to the problem. I have let Firefox continue to run for up to 10 minutes, with no change in responsiveness. I am forced to kill it every time. It is 100% reproducible on my system.

I just discovered that if I disable the Quicktime plugin (7.6.6), this problem goes away.

On my PC, iTunes 11.0.3.42 causes it to hang when attempting to view a .MOV (1.6GB) requiring a cold boot. What could be causing this?

On my PC running windows XP Service Pack 3, iTunes 11.0.3.42 causes it to hang when attempting to view a .MOV (1.6 GB) requiring a cold boot. What could be causing this? Corrupted .MOV? Too little RAM? It successfully plays a 162 MB .MOV.

Hello David,
Thank you for providing all that information about the iTunes issue you are experiencing. We would first want to rule out any software issues before we can determine if it has to do with RAM. I found an article that will help you isolate and troubleshoot software issues that could be causing iTunes to behave this way:

I hope this helps you get back on track with watching movies in iTunes!

When attempting to view the date track history for one employee, errors out

Hi All
When I attempt to view the date track history for one employee, it gives errors.
To get the details, the navigation is :
1. Search for employee xxxxxx
2. click on Assignment button
3. click on Date Track History.
4. Receive error APP-DT-52554.
5. Click OK on error message
6. click on Full History button.
7. Receive error APP-PAY-06153
What could be the problem and how to solve this?
Regards
Rahman

Sounds as if there is an inconsistency with the date tracked records. Can you check the records through TOAD or SQL Plus?
Have alook at MetaLInk article 343070.1 which refers to the second error message.

Firefox hangs when accessing video and the process has to be killed

Relatively new problem. Seems to affect version 5 as well as older versions. Running current version of Adobe Flash. Firefox hangs COMPLETELY. No buttons of any sort are active. Have to use procexp.exe to kill Firefox. Just before the hang it says one of the following: Waiting for AD-g.doubleclick.net or Waiting for Motifcdn2.doubleclick.net or Waiting for Static.inplay.tubemogul.com or Transferring data from S0.mdn.net. If I leave machine running with Firefox hung in this state, the machine eventually gets Blue Screen Of Death. None of this happens when I use Internet Explorer to access exactly the same sites and videos (Youtube for example but the problem is NOT confined to Youtube. It seems to randomly occur even in yahoo videos.) I am a software engineer with only 45 years continuous experience writing scientific software so it could be me? :-) I've tried Firefox 3.6.8, the update to that (was it 3.6.18 or something), and Firefox 5.0. Also tried an older version of flash but nothing seems to help. Again Internet Explorer is NOT having these problems. I will be using IE as primary until whatever is wrong is fixed... Darn! I really liked FireFox... Thanks!

At this point we want to pinpoint exactly where in your code this behavior is originating from. Try running the included examples which can be found here:
C:\Program Files\National Instruments\MeasurementStudio\CVI\samples\IMAQ\Display
C:\Program Files\National Instruments\MeasurementStudio\CVI\samples\Vision\1.GettingStarted
and see if you experience the same behavior. If we still experience this, then we know that it is a setting within the functions that we need to change. If not, we know that it is somewhere else in the code of the bigger project which is the culprit.

Firefox hangs when maximising FF windows or ALT+TAB cycling

Hello. Im having bad performance issues since upgrading to 3.6.3 which I've never experienced before. I appreciate you cannot help me due to extremely poor detail on my behalf. I thought it worth asking for possible remedy in the hope that its a problem experienced by many.
The problem is more likely to occur when many Firefox windows & tabs are open and other memory hungry packages ie GTA Libery City are using all available memory resource.
Firefox will either not respond ( wont maximise window ) or the Firefox window appears, navigation icons are visible but remainder of page is blank/white. The symptons are very similar to any package running in windows thats forced to wait whilst windows pages memory.
As I can never guarantee to reproduce, I cannot say for certain what events are likely to trigger.
I have noticed that more tabs/windows open the greater the probability of a problem and im fairly certain any webpage running java increases probability of a problem. This isnt caused by insufficient hardware resources because other packages ie uTorrent respond without problem in a split second.
I can wait from 10 seconds to 2 minutes before FF begins to respond. Sometimes I have to close FF totally.
I've read FAQs http://support.mozilla.com/en-US/kb/Firefox+hangs#Hang_loading_every_window and well the FF open a long time to shutdown/restart and hmm it could be said power cycling pc or restarting FF is a solution, but those kind of solutions faded away with Windows98.
I dont plan to start changing task priorities or setting CPU affinity etc as a permanent solution.
Im thinking solutions available are:
Reload an older version of FF.
But before I do, I thought I would post and see if its a problem due to be fixed or if you think the problem is worth a deeper look and wish me to provide more data.
I apologise for reporting a problem in such a vague manner but Im struggling to find any facts that I believe are relevant and usefull to you. I susoect you will be unable to help..
But anyway.. a Huge Thankyou to all the peeps who've contributed to making FF a top quality program.
== This happened ==
Not sure how often
== Since automatic update to v3.63

Reverting to an old version of FF worked!!! WHOOHOOOOO!!!!!!

We have updated the dpm agents on all of the servers that we back up by installing the update on the servers manually and according to the data in the DPM database it has acknowledged that they are indeed updated.
From what I can tell from the errors is the console is attempting to read the updateprotectionstatus from the database and it is not returning a value and thus causing it to crash. but I have no clue as to where this might be in the database to even
check if it simply missing from an update gone wrong.
I did notice that the update attempted to install twice through windows update and failed. The update does show as installed under installed updates in programs and features control panel
Any help on this would be appreciated as it does make it difficult to manage our dpm server

Hi,
See if this is relevant.
1. Take a DPMDB backup.
2. Open SQL Management studio and connect to the DPM instance.
3. Expand the DPM database and go to the table tbl_AM_Server.
4. Edit the table, and under the "ServerName" column check for the DPM server name. It should be the FQDN. If it is the NetBIOS name then change it to the FQDN.
5. Try re-opening the DPM console and navigate to the management tab and see if that works now.

When viewing the applications tab of my firefox preferences, PDF file formats are not in the list of possible formatts, how do I add it so that I can open PDF file in my browser?

I am running OSX 10.5.8 currently, and have followed all of the tips and advice on the help sites (IE. uninstalling, installing pluggins, programs like adobe, and reinstalling firefox). I tried deleting and resetting the mimetypes.rdf file and the pluginreg.dat files. I have noticed that when you open the FF preferences window, and look at applications, there is no Portable Document Format file type listed. How do I fix this?

Install '''PDFescape''' extension from the FF add-on gallery. I think it may help to your problem

I did some digging around on the internet and the discussion forums, but the only issue I've seen that is close to this is that it happens when the iTunes Store is accessed. For me, the program fails to start altogher.
Also, please don't advise me to 'Download a newer version of iTunes', I am working on fixing some older iDevices.
All help is appreciated, and thanks in advanced!

I found this and it worked!!!

Sep 26, 2013 5:43 AM (in response to Bristol1981a)
I had this exact same problem. I found a fix on another support post that worked perfectly for me. Browse to C:\Program Files (x86)\Common Files\Apple\Apple Application Support and copy the filen named QTMovieWin.dll. Then browse and past that file into C:\Program Files (x86)\iTunes.
Hope this helps you. My iTunes store is working fine now.
God bless!!

Every time I try to view the music tab on iTunes it states an error: new null response. Can someone please help?

Hi,
Could someone kindly please help with my iTunes Store error? When attempting to view the music tab on iTunes store on my iPad 3 states the following error: new null response and cannot connect to iTunes Store.
It's extremely annoying as I only bought a new album yesterday and its suddenly got an error. I can use the films and tv programmes tabs which is strange, so its only the music tab not working. I have tried everything from other websites and blogs but nothing is working for me.
I hope someone can help?
Thanks

Hello there Mattspur,
I recommend sections 1, 3, and 5 of the iPad Troubleshooting Assistant found here http://www.apple.com/support/ipad/assistant/ipad/. If you get to section 3 I suggest closing ALL the apps.
Here is section 1 to get you starrted:
Restart iPad
To restart iPad, first turn iPad off by pressing and holding the Sleep/Wake button until a red slider appears. Slide your finger across the slider and iPad will turn off after a few moments.
Next, turn iPad on by pressing and holding the Sleep/Wake button until the Apple logo appears.
Is iPad not responding? To reset iPad, press and hold the Sleep/Wake button and the Home button at the same time for at least 10 seconds, until the Apple logo appears.
If your device does not turn on or displays a red battery icon, try recharging next.
IF that does not resolve the issue, I would take a look at these articles next.

Java error when attempting to view projects tab in Rel 8.0

Hi,
When attempting to view the projects, resources or administrator settings in the Web app of P6 Rel 8.0 I get a message saying error, click for details in the display section of the page.
I had Java ver 6.24 installed on the laptop. I removed this and installed ver 6.20 as required for Rel 8.0.
I can logon, view dashboard information, the error only comes up with Projects, Resources and attempting to view the administrator settings.
I have cleared the cache in Internet explorer and the java console.
Any help appreciated

Office 2007, by default, saves with a docx extension, unless you specify to save it in an older format. It sounds like the document reader on the BB is not handling the document the way Office 2007 converts it, but the full version of Word 2003 on your computer is opening it fine.
Then, when it is saved in Office/Word 2003, it DOES work with your reader. Perhaps an update to the reader software on the BB is needed so it will properly handle the converted docx to doc files?

How do I add content types in the Applications section under Preferences

I have several applications I use regularly on multiple macs. For specific file types, Firefox 4 will only give me the option to save the file. It does not allow me to select an app to use, and, the file type is not listed in the Content Type list on the Applications tab in Preferences.
In particular, I have XLS associated with Excel, but XLSX is not listed, so all I can ever do is save it, then open it.
Another case, on one mac, PDF is associated with Preview, but it is not listed on the other, so again, all I can do is save it. It doesn't allow me the option to change actions.
There must be a place to change the default behavior for unknown file types, isn't there?

You can look at this extension:
*MIME Edit: http://space.geocities.yahoo.co.jp/gl/alice0775/view/20080912/1221150790
* User Info for White Alice0775: https://addons.mozilla.org/en-US/firefox/user/84420/

Why does is the Content tab in Preferences missing?

When I try to view the Content tab in Preferences, it shows the last tab I clicked on. For example, when I click on Tabs and then try to view the Content tab, it shows the Tabs tab.

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
