After upgrade to 3.6.6, firefox must run as administrator

I'm running firefox on Vista. I just upgraded to 3.6.6. I had to log in to my admin account in order to do the upgrade. After the upgrade, in my normal working account, I must run as admin or firefox simply hangs and attempts to load the page for ever.
== This happened ==
Every time Firefox opened
== I upgraded to 3.6.6

Does anyone know how to fix this problem???

Thanks so much Anonymouseuser. This fixed it. Ironic that the plugin Firefox used to prevent freezes actually causes freezes. This so fixed my problem. http://www.technogadge.com/how-to-stop-firefox-plugin-container-exe-process/

After upgrading to Windows 8.1 firefox longer works. I got it to load but screen is either blank or doesn't go to target address

after upgrading to Windows 8.1 from 8 nothing works correctly. Firefox 1st received 'unable to load XPcom' After resetting and uninstalling several times Firefox now loads to either a support screen or blank screen. It accepts address input but doesn't execute to target. So far I have been unable to roll back upgrade.
Although IE11 works, it doesn't work correctly.

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.

If you keep having problems then do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
Download a fresh Firefox copy and save the file to the desktop.

Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you lose personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

After upgrade to version 20 of Firefox websites do not display anymore. Seems like v20 does not work well with ISA

After upgrade to version 20, we receive the following error when trying to open a website:
Error Code: 502 Proxy Error. The ISA Server denied the specified Uniform Resource Locator (URL). (12202)
Everything worked fine in the previous version of Firefox.

Found the fix for this:
Just set the following values to false in about:config.
network.automatic-ntlm-auth.allow-proxies
network.negotiate-auth.allow-proxies

After upgrade: Error code: ssl_error_ssl_disabled in Firefox 3.6.10 Mac OS 10.6.4 - no mozilla-based "solution" works!

In Firefox settings: SSL 3.0 is used, no proxy, network.dns.disableIPv6 set to true. The Mac OS firewall has been tested as turned off/on, but still no secure website (e.g. gmail) can be loaded. This happened first after the upgrade to 3.6.6. I then trashed 3.6.6, freshly installed 3.6.10 from scratch, same thing.
What a ridiculous glitch... wasted 3 hours on this already. About to move to other browsers after many years on firefox...
The whole error message (note the website.... )===========
Secure Connection Failed
An error occurred during a connection to support.mozilla.com.
Can't connect securely because the SSL protocol has been disabled.

yes - I have the same issue on four different people's new MacBook Pro's on 10.6.4. I have deleted the Profiles numerous times, but the issue still occurs at least once every two weeks.

After upgrading to 8.0.1 Firefox will download but not install extensions after upgrading to 8.0.1

Windows Vista. Avast Antivirus with Sandbox feature.
Outside Sandbox - all extensions available. Within Sandbox - no extensions available and not able to install any extensions. ie Adblock Plus, No Script etc.
Before upgrading to 8.0.1 no problems in either mode. Add-ons appear to be intact in either mode.
When attempting to install an extension after downloading:
"(extension) could not be installed because Firefox cannot modify the needed file".
Reluctant to delete pluginreg dat file because all extensions are working outside Sandbox.

Hi,
You may have to "trust' the upgraded Firefox, if there is such a setting in Avast and install extensions after starting Firefox outside of the sandbox - normally. Not sure about Avast, but usually a sandbox would mean a virtual area like hard disk storage, registry settings etc. for the sandboxed app and once the application is closed or the computer is shutdown, everything that was done by the app or via the app is sort of vaporized and the application and it's settings are returned to it's previous permanent state.

After upgrade to 3.6.9 Firefox would not load

After allowing the update to 3.6.9 Firefox did not automatically reload.
Nor could it be loaded manually.
I restarted my pc to see if that made a difference.
A Firefox update box flashed up and disappeared (sorry I didn't see the detail.
Firefox would still not load.
I downloaded a new Firefox Setup (using IE) and reinstalled.
Works fine now.
Have others experienced problems with this update?

We are currently typing on the computer we have been discussing about in our microblogs; which is a Window 2000 Professional OS. Apparently, the problem is not completely resolved, because we removed the Firefox Browser from it. But due to the update, we are also experiencing Security Certificate Issues as well. Following the update on or around Sept. 10th, 2010, we notice that the Firefox Browser constantly asked for a security certificate verification on frequent web pages we visited. Well, apparently this situation is continuing on a totally different Internet Browser. This computer is clean of virus(es) & malware...so that is not the issue. We suspect that the update from Firefox may have change some internal security configurations in Windows Operating Systems. Noting the Comment from a Window 7 user, the Firefox Bug has possibly caused internal issues in all Windows Operating Systems.

AFTER UPGRADING TO LATEST VERSION OF FIREFOX( FOR MAC) ALL WEB SITES ARE VERY SLOW TO LOAD. I HAVE NO PROBLE WITH SAFARI. WHAT DO I DO?

confirmed e-mail [email protected]

Yours is the first complaint about Firefox on 10.8 I've seen, so I'm inclined to think it's a issue with your machine, or a bad download/update or something.

After upgrade to v6, while surfing, Firefox opens active tab in new window few times in hour... why?

I am using laptop. When I click on some link or in some text field or when I start typing on gsmarena.com in search box... Firefox opens new window with the currently active TAB. This is very anoying and I thought that it will be OK but now it started to happen on PC also. It is not happening always with the same actions and is hardly reproduced.

Make sure that you do not drag a tab in the browser window. 
Firefox 3.5 versions and later have a feature called tear-off tabs. 
You can detach a tab from the current window and open it in a new window by dragging a tab in the browser window. 
You can drag that tab back to the tab bar in the original window to undo that detaching.

Itunes must "run as administrator"

Just recently iTunes, installed on Windows 7, wont start if it is not runned as administrator.
The consequence is also that it cannot synchronise aTV, since this also seems to collide with the needs for Admin rights.
The user account has admin priviledges.
Any suggestions?

I see this is an older post originally that was replied to recently on Nov 18. I also had this problem today and found that "Run as Administrator" fixed the problem to an extent. If I minimized iTunes to the taskbar player, it would not function and would require me to restart iTunes. I found the solution to my problem at: http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_programs/itun es-application-could-not-be-opened-you-do-not/610864d3-b8ba-44f0-bad6-1c5e49b7e0 0b
My problem was not iTunes. It was Media Center. I changed the libraries included in it and it changed the permissions to my music folder. iTunes couldn't access it without the elevated admin permissions, so it had the issue. I went through the C: drive to my music folder and re-established permission and iTunes works perfectly again. Maybe this can help others as well, as I personally did not like the idea of having to run admin all the time like this.

Do a clean (re)install and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can skip the step to create a new profile, that is not necessary for this issue.

I cannot compose or reply to email messages in gmail after upgrade to 3.6.12. Shows :Loading". Gmail works ok in IE.

After upgrade to 3.6.12 Firefox I cannot compose an email in Gmail. Shows that Gmail in "loading".
Gmail works in IE. No problems before upgrade.

Did check the pref dom.storage.enabled and make sure that the value is true?
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page.

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