After updating firefox the first window after opening first time "checking compatibility of add-ons" window is froze won't progress pas 1/3 of completion

I updated my fire fox on my MAC OS X to 3.6.6 version of firefox, everything went smooth till I open FireFox then the window firefox update opens up and about 1/3 through the process it gets stuck on Checking Compatibility of Add-ons and doesn't go any further. I have hit cancel and firefox opens but it doesn't open any web sites. I have removed firefox and re-installed and it is still doing the same thing. I have also let it run over night thinking it may just take a while and it never progresses, please advise, I am new to MAC but FireFox is the only browser on my mac that will open one of my business pages, known issue with mac for this company.

Try "Reset all user preferences to Firefox defaults" on the [[Safe mode]] start window - See http://kb.mozillazine.org/Resetting_preferences
Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled extensions that are not compatible on the next start in "Tools > Add-ons > Extensions" then click the "Find Updates" button to do a compatibility check.

Just updated to v5.0 and now when I start Firefox I get a pop-up that says checking compatability of add ons and the the Welcome to Firefox page and my home page appears. Can't get rid of the pop up or welcome page.

Above question covers it. I've tried reinstalling Firefox, clearing cache, history, etc. but still happens. I've created app tabs and when I restart Firefox, they are gone. Running Windows XP.

It is probably because you are not properly closing Firefox. Restarting your system would make sure that Firefox had terminated, but you do not have to do that.
To properly close Firefox on Windows systems, use
:File > Exit or "Firefox:" button > Exit
When you get the message "Firefox is already running" it is too late, and you must force termination of Firefox through the Windows Task Manager before restarting Firefox. Windows 7 has a keyboard shortcut to save you a step "Ctrl+Shift+Esc" then on "Processes" tab, select "firefox.exe" and use the "End Process" button. More thorough would be to right-click on the "firefox.exec" and choose "End Process Tree".
You would find firefox.exe in a Mozilla folder in your program files, but y0u would not want to delete it there, you would need to use the Control Panel which you have already identified and do it from there -- but generally you would not need to do that, and there is nothing in what you have posted to indicate that you should. But if you did do that, then don't let the install start Firefox for you as you would want to use you existing desktop icon or method of starting Firefox, and should decline having Firefox install start Firefox for you. When the install starts then invoke Firefox in your normal manner. This should eliminate problems of creating a new profile rather than using your old profile.

Checking compatibility of add-ons always running after update

After updating Firefox to version 6, the checking compatibility of add-ons is always running with each start of Firefox, and "Welcome to Firefox" site is always opening as well.
This is very disturbing.

Apparently I wasn't clear or the word upgrade wasn't right. I meant going from 4 to 5. I downloaded it, installed it and got no option resembling that at all, it just saved a DMG to my hard drive and then told me to put it in my applications folder as always. I opened it and that was that, no compatibility check. I already got one error about an add-on that's vital. I'd backed up before I installed and saved Firefox 4 as a separate file before opening 5, I hope I'll be able to go back to it. The old system was really much better, what's the point of finding out after you already installed something if your systems will work? Or of avoiding installing because you're afraid they might not when everything very well might be fine? I can guarantee you that I won't be installing an major updates for a very long time, that's for damn sure.

"Checking Compatability of Add-ons" Update window at each startup & redirects to a welcome page. Tried disabling all add-ons & updates / force compatability checker. Thoughts?

Each time I start Firefox a "Checking Compatibility of Add-ons" update window appears, which redirects me to a welcome to Firefox 5.0 page with my normal home page in another tab. I tried disabling all add-ons and updates as well as the force compatibility checker. I think my AVG safe-search bar might be causing the problem, but I have it disabled and never use it. Please help me get rid of this.

I am not clear what your problem is and importantly whether you are trying to ask for help with Firefox.
If you have a Firefox problem can you explain what you need help with please. If the problem is with a new Windows 8 operating system you will need to find a suitable forum to discuss that.
A websearch will turn up many suitable fora one possibility is

How do I completely disable initial "Checking Compatibility of Add-ons" pop-up for all users on a Citrix server where the FireFox was upgraded to 29.0.1

I have a set of Citrix servers, we need to upgrade the FireFox on them to 29.0.1
When I have done this, and a user runs FireFox, now the users are being presented with a pop-up "Checking Compatibility of Add-ons" which delays the start of FireFox.
I need to prevent this so users just see FireFox start up without any delays.
I have installed the add-on that re-enables extensions.checkCompatibility and tried various ways of implementing it like pref("extensions.checkCompatibility", false);
However we seem to have a situation where the add-on that enables the setting is not loaded yet so the setting is not implemented.
How do I solve this for all users?

You can try to set the browser.startup.homepage_override.mstone pref to ignore on the about:config
*http://kb.mozillazine.org/browser.startup.homepage_override.mstone
You can use a mozilla.cfg file in the Firefox program folder to specify new (default) values and possibly lock prefs.
Place a local-settings.js file in the defaults\pref folder where also the channel-prefs.js file is located to specify using mozilla.cfg.
pref("general.config.filename", "mozilla.cfg");
These functions can be used in the mozilla.cfg file:
defaultPref(); // set new default value
pref(); // set pref, but allow changes in current session
lockPref(); // lock pref, disallow changes

Firefox checking compatibility of add-ons every time it starts.

Every time I upgrade, Firefox begins checking compatibility of add-ons every time it starts. And it brings up the "Hooray! Your Firefox is up to date" page every time too. How to fix?

After updating to the ladtest OS my iPhone most time goes blank when I unlock it and does not recognize my finger print not show the passcode to enter. Screen just brightens up and stays blank.

after updating to the latest operating system on my iPhone 5s, often my screen goes blank and I am unable to unlock my phone. The phone becomes completely non responsive . Since I have the soft touch home button enabled I will either call Siri and ask to open an app which solves the issue or if I don't have Internet then the only solution is to switch off and then switd

Hello there, Prashanthds96.
The following Knowledge Base article offers up some great steps for troubleshooting issues with an iPhone not turning on:
iPhone: Hardware troubleshooting
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

After updating Firefox it will no longer open and i get the message "firefox.exe has encountered a problem and needs to close" end of story.

Firefox was working well. One day I logged on to use Firefox and was prompted to update my version which I did. After or during the update the following message was given on the screen "firefox has encountered a problem and needs to close". It closed and now every time I click on the firefox icon I get the same message from Microsoft. That is all the information I get. Each time I go to open Firefox I get the same message. There is an error message attached to the Microsoft dialog box, but I don't understand what it means.
I have sent it to Microsoft but no reply.

Make sure that you aren't running Firefox in some compatibility mode (e.g. [http://en.wikipedia.org/wiki/Rosetta_%28software%29 Rosetta]).

After updating Firefox, I am unable to open word attachments from my Outlook email, although the download works when I check emails in Internet Explorer

Following a Mozilla update, Jave console has been disabled and is incompatible with the new upgrade. I'm not sure if this is affecting my ability to open word documents that are attached to email, but I am unable to do this when I open my emails though Firefox. If I open them in Internet Explorer, the .doc file will open normally. I just prefer to use firefox rather that internet explorer

I just got off the phone with support. First, he claimed that WAV files are not supported (although the user guide claims it is). Next, he suggested that WAV files that are transfered through BB Desktop will work, but not files that are downloaded from attachments. Finally, he stated that the file must be in the Music folder in order to work. I was able to use AIR Browser to move the file over to the Music folder, but it still won't play. When BB Desktop syncs music files over, does it create a specific subdirectory in the Music folder? Has anyone been able to get a WAV file to play (regardless of how it got on to the PlayBook)?

After updating itunes, the program doesn't open anymore- audioconfigeration

hi!
after i updated my itunes some days ago, the program does not open anymore. there is just a message saying, that itunes cannot start, because it has discovered a problem with my audioconfigeration (i don't know if this is the right word for it, because the message is in german "Audiokonfiguration").
i'm so desperate. i tried to repair the program, but the problem is still there. i'm afraid to reinstall it, because of my songs (are they gone then?)...
regards,
green123

(i don't know if this is the right word for it, because the message is in german "Audiokonfiguration").
that one is typically caused by a problem with your QuickTime. (iTunes uses QuickTime for audio and video playback.)
the following document may be of some assistance:
iTunes 7 for Windows: iTunes had detected an audio configuration problem
(the German version of this document is still calling this the -200 error ... which is how it used to present to folks using iTunes 7.0.0.70 and 7.0.1.8.)

After updating Firefox I am getting this message any time I do anything "Exc in ev handl:Error: Bad NPObject as private data"

This error happens each time I use Mozilla. especially when I click on an extension or try to work in any of my e-mail accounts (Yahoo, Gmail, or RCN). Sometimes I am able to continue by just clicking OK and other times it prevents me from completing my task. This started happening right after I downloaded and installed your latest version of Firefox. I see others are having the same problem. Error message is "Exc in ev handl:Error: Bad NPObject as private data"

That issue can be caused by the McAfee Site Advisor extension
*https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration 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.

With version 5, on starting get a box "checking compatibility of add-ons" then to Firefox home page not my home page--What's happening?

Just installed version 5. As above I get the box then it goes to Firefox home page not my home page. I've updated and/or disabled every add-on or extension and it made no difference. I am in a university behind a tough firewall. I'd love to go back to version 4 but that isn't available.

Disabled add-ons will still be checked and can still be updated.
I don't know why you are continuously getting the message, you should only get it when there is a version change.
You can try solutions in https://support.mozilla.com/questions/817681 but you had better make a list of what extensions you had disabled first, because all of your extensions will be enabled when you delete/rename those files in your profile. You can use about:support to get a list of your extensions. (renaming is safer than deleting).

After updating firefox to 6.0.1 and again after 6.0.2, Firefox checks compatibility of add-ons on EVERY start, and also resets the homepage back to default. How can I fix this?

The problem persists with Firefox in Safe Mode

After updating Firefox, the "What's New" page doesn't say what bugs have been fixed

I updated from 3.6.9 to 3.6.10. When restarted, Firefox displayed this page: http://www.mozilla.com/en-US/firefox/3.6.10/whatsnew/
Supposedly it describes what's new in 3.6.10, but all it has is what's new in 3.6. Nothing about what bugs have been fixed.

This is only a chemspill release to fix a crash.
