Firefox updated itself today and now won't open. I tried starting the Profile Manager as directed by the knowledge base and that won't start. What next?

When I click on the Firefox icon, nothing shows up but it apparently is running in the background. I used Firefox yesterday and have not changed anything on my desktop, running XP, since then. This all happened with the automatic update

It is not always necessary to create a new profile.<br />
Easiest is to use: Help > Troubleshooting Information > Profile Directory > Open Containing folder
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]]
If it happens after an update then a possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.

Hello maddisonsf
Try downloading iTunes from the link below and run the installer that comes with it to see if that resolves the issue of not starting up for you.

Firefox will no longer open and I can not get the profile manager to open either. What do I do?

I tried to open firefox this morning, and it would not open. I tried to uninstall and reinstall several times and even deleted all of my information. I looked it up on your site, and it said to open the profile manager. I followed the directions on how to open it, and it too will not open. I tried several times to open it as well. I need help. I only use firefox and have for years, and I have never had this problem. What do I do?

A possible cause is security software (firewall,anti-virus) that 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 internet for Firefox and the plugin-container process and the updater process.

Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

I'm trying create a new firefox profile and everytime I try to start the profile manager it crashes. I'm running the latest verison of firefox and OS X 10.5.8

The way I've been starting the profile manager is by running the command /Applications/Firefox.app/Contents/MacOS/firefox-bin -p in the terminal.

When trying to start Firefox I keep getting message saying "A copy of Firefox is already open. Only one copy of Firefox can be open at a time." I've started a new Profile but Profile Manager keeps telling me the Default one is still in use.

When trying to start Firefox again I got a message saying "Close Firefox. A copy of Firefox is already open. Only one copy of Firefox can be open at a time." This question is addressed in Mozillazine but nothing I've tried from there seems to work. I started a new Profile from the Profile Manager which at least gets me up and functioning, but weirdly enough the Manager also tells me the old (Default) profile is still running, though I can't find a way to close it. I also can't find the Default profile in my profile manager. can anyone help?
== This happened ==
Just once or twice
== i thought I'd exited Firefox and was going in again.

Had this problem on my MacBook after I deleted my profile (the profile folder is named something like asd8f7as.default). The solution for me was to open profiles.ini and delete the information about the profile I had deleted. It should look something like this:
[Profile0]
Name=default
IsRelative=1
Path=Profiles/2xr4hi1g.default
Delete, save, problem solved.

I have just agreed to software updates on my imac and now can't open my mail. There is a message saying this version of mail isn't compatible with this latest software. I have located the updated mail in the applications folder but it won't open. Help!

I have just agreed to software updates on my imac and now can't open my mail. There is a message saying this version of mail isn't compatible with this latest software. I have located the updated mail in the applications folder but it won't open. I don't have the original operating software disk. Does anyone have any suggestions?

Your reply suggests that you have moved Mail to a different location, which (as I said) will prevent it from being properly updated. You cannot use Mail 4.5 with any recent version of Mac OS X. Mac OS X 10.7 (Lion) included Mail 5 and Mac OS X 10.8 (Mountain Lion) includes Mail 6. I'm assuming that you have either Lion or Mountain Lion, but if that is incorrect, you will need to provide that information.
At this point, you will need to reinstall your system. Hold down command-R at startup and reinstall the system right on top of the old one. This should not disturb any of your documents or applications, though you should have backups beforehand in case something goes wrong. And at this point, with your system in an uncertain state (I don't entirely know what you have done to it), something could go wrong.
You will also want to delete the old copy of Mail 4.5, wherever that is. You can't use it.
In the future, do not move any of the preinstalled applications. Leave them where they are.

Downloaded Firefox update for my Mac and now when I open it, there is a white box at the top of the page with a grey bar in it that I can't get rid of

I updated my firefox browser for my Mac and now, when I open it, an empty white box appears at the top of the page with only a gray bar in it. It over lays the Firefox home page and I can't get rid of it, so I can't click on anything on the Firefox page. I tried deleting Firefox and redownloading it, but that didn't help. I have to force quite Firefox to get out of it. Help!

hello, can you try to replicate this behaviour when you launch firefox in safe mode once? if not, maybe an addon is interfering here...

Have you run Software Update. You have Java already installed, but it needs to be updated.

While updating software on my iPod touch 4 my computerswitched itself off and now iTunes is asking me to restore to original settings but there are photos on my iPod that have not been backed up. Am I going to lose them?

While updating software on my iPod touch my computer switched itself off and now iTunes is asking me to restore to original settings. I have photos on my iPod that were not backed up so will I lose them if I resore to original settings? If so is there any way I can get them back?

After you restore to factory settings/new iPod you can restore from backup. See:
iOS: How to back up
That is your only choice

Firefox will not open - I have reinstalled and used the profile manager solution. It was fine earlier today. IE working fine.

I tried the suggested solutions including the 'clean install', any help would be most appreciated. I've used the Profile Manager, which is not much use when the browser won't even open to test it. I've also reinstalled twice, installed updates and restarted numerous times.
Firefox does do this on occasion, but usually sorts itself out - not this time.
Help!

Therefore i ask the question and hope somebody can give an answer an describe this behaviour.

After Firefox updated itself to 3.6.12 I lost sound regarding all facebook applications

after Firefox updated itself to 3.6.12 I lost sound regarding all facebook applications and videos. I have installed the latest flash and that doesn't solve the problem

After Firefox updated to 3.6.12, my homepage stated that I did not have the Flash Player installed. The latest player was installed, but I uninstalled and attempted to re-install. The installation process worked, but the Adobe Flash banner on their page does not Flash like when a proper install occurs. The Adobe DLM add on will not allow me to change options on Firefox Addon page. Now Flash content on homepage will not play, and I am forced to use IE to view content.

I updated itunes and now it wont open

i updated itunes and now it wont open and keeps giving me an error message MSVCR80.dll is missing. what do i do? i dont want to lose everything

Hi there,
Earlier iTunes (and supporting applications) need to be completely uninstalled before you can install the new version. Here's the complete Apple info on this: http://support.apple.com/kb/HT1923
Mobile device application will most likely fail to uninstall, so you would need to visit its location(s) and manually delete the files then folder(s). The location of the folders is documented in this link from Apple.
You won't lose your music when you uninstall iTunes. It's located in your music folder and won't be touched.

For some reason if I click a link that needs to open in a new window, the new window is blank. This just started happening when firefox updated itself last time

Ever since firefox automatically updated itself, I am not able to open websites in new windows - meaning that if I am on a website and you click a link on it that opens in a new window, that new window is blank. It used to work perfectly. I even checked my foxit reader and that it working well

Hello Angelika.
I should bring your attention to the fact that your user agent says you're using Firefox 3.6, not 3.0. I will remind you that Firefox 3.0 has been discontinued and is no longer supported. Furthermore, it has known bugs and security problems.
As for your problem, you may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author.

Firefox updated itself today and now won't open. I tried starting the Profile Manager as directed by the knowledge base and that won't start. What next?
