Firefox won't start. After starting the browser, it shows that it's running in task manger for a while, but then it disappears.

It works in the safe mode with networking though.

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 internet for Firefox and the plugin-container process and the updater process.

Firefox won't open when prompted the first time. Says "Not Responding". I have to hit cntrl/alt/del then try starting again. Sometimes multiple times.

Sounds like a "hang at exit" problem. There are several possible causes for that error. See:

Hi. I am running Windows 8.1 on a 64 bit Toshiba Satellite P70-A laptop with 16Gb of RAM. I have installed Adobe Creative Suite 6 - Master Collection. All is fine except for Adobe Acrobat X. It runs OK for a while, but then suddenly it won't work. I uninstall it, re-boot and re-install again, bit the same process repeats itself and once again I have to uninstall and re-install again. I don't know if windows update interferes with it? Has anyone else had a similar problem? Is it fixable?

I think you'd be much better off asking in the Acrobar forum, Acrobat

Forms process won't stop after closing the browser

I am running the Forms (904) in the application server. When I close the browser, the forms process (on the server) ifweb90.exe won't stop on the server.
Is there a message that can be catched when the browser is closed? thanks.
I am running the forms on XP.

Hi,
the forms processes on the middle tier will stop when the listener servlet recognises that the client applet doesn´t exist anymore.
The amount of time the listener servlet needs to recognize that the client applet doesn´t exist anymore depends on the "heartbeat" and the "timeout" Parameters configured in the formsweb.cfg Configuration File of the Oracle Webforms Installation.
Normally you don´t have to worry about these parameters their default values will fit the most environments.

Firefox 5 works for a while but then won't open webpages and has to be restarted. Happened with F4 too.

Running OSX 10.6.8 on a 2-year-old MacBook Pro. Everything will be working fine and then after a random interval of time (anywhere from 5 minutes to hours), Firefox won't connect to the internet any more and will display an error message.
I posted a question when this happened in Firefox 4 and it was never resolved.

You can try disabling emoticons and image previews in your IM appearance settings in your Skype options to see if that changes anything. Some people running Windows XP have had odd graphical and resource issues with versions of Skype above 7.5. The alternative solution would be to downgrade to Skype 7.5 for the time being. You can find links to 7.5 in the thread below. http://community.skype.com/t5/Windows-desktop-client/Skype-7-6-crashes-on-startup/m-p/4031560/highlight/true#M353247

I have an iPhone 4s (black) and the speaker in the ear is not working. It was for a while but then cut out. If I take it to the apple store can they clean or fix it?

When I use it on the speaker it's fine. But when I answer or make a call it's so quiet and you can barely hear!!! Frustrating

Number one - that person has given you false information...the Apple store genius bar supports all Apple products whether in or out of warranty. Checking is free, service on an out of warranty item is not free.
Try a reboot by holding both the power and home buttons until the apple logo appears, ignore the red slider if that appears.
Since you show that you have iOS 7.0.3 you might want to update that iOS to 7.0.4...plug the iPhone in so you are on a solid power source, then while on a WiFi go to Settings > General > Software Update and update to 7.0.4.

Firefox won.t start up browser when my meta 4 is on, even when I shut off meta4 It says firefox is still running?

In order to start browser I have to restart my computer. I need to know if there is a way to run both? I had to delete mozilla from my computer so I could run meta4. I'm using chrome now and it works with meta4 on, but I would like firefox back.

What do you mean with ''meta4'' ?
Do you mean the Firefox 4.0 beta version?

My safari keeps crashing while watching movies/TV shows. No error messages. Just disappears. I have to start it up and it'll run for a while and then repeat disappearing. What's up? Apple wants to charge me but this is only since updating to 10.10.1

What is going on? I have never had this problem until I updated to OS 10.10.1. Now apple Tech Support wants to charge me to look into it. It crashes with no error message.

B,
Dag-nabbit! That's what I'm talking about. I installed AdwareMedic and I have every expectation that I'll see great results. I'll have to follow up with a donation. I'm not very savy and you guys have helped me with new confidence. Thank you from the bottom of my heart.
Now, any possibility someone can help me with backing-up with time machine?? My old external hard drive went south and I had to get a new one. Now I can't get it backed-up because it takes too long. There is to much to back-up for an initial try. My computer ends up shutting down/going to sleep and it can't finished a complete back-up. It seems to want to take about 18-20 hours as best as I can remember. I used to be so anal about my back-ups now I am completely disillusioned.

Updated to FireFox 11 and I keep getting "checking compatibility of add-on" when I start the browser.

I just updated to FireFox 11 and whenever I start the browser, I get that annoying window that checks for the compatibility of add-ons.
I have looked around for solutions and have tried the following:
1. Deleting several extension files from the profile folder.
2. Going to about:config to disable the extension:checkcompatibility (does not exist there).
None of these worked.

Did you try to delete the file prefs.js?
*http://kb.mozillazine.org/Preferences_not_saved
*https://support.mozilla.org/kb/Preferences+are+not+saved
Which security software (firewall, anti-virus) do you have?
Some security software has virtualization features that can cause problems by protecting and restoring files in the Firefox profile folder.

I do not see much about coloum 14, but I am guessing this file is stored somewhere and its corrupt. Update.xul suggests that it is the update file. Do you still have this in your downloads folder? There are two places for update and for a clean reinstall:
[http://www.mozilla.org/en-US/firefox/new/] in a private window will give you a new install or you can choose from here: [https://www.mozilla.org/en-US/firefox/all/]
This is what the file should look like; [http://hg.mozilla.org/mozilla-central/log/7a2edc5171e6/toolkit/mozapps/extensions/content/update.xul] If you can copy and paste that file from a working browser we can see the issue, but it will just look the same as the error.
if you can replace the contents of the file locally with what it should look like it will fix the error, but who knows if there are other errors. May be best to delete the updater and save all the profile folder contents.
