After 8.0.1, Firefox continually asks to reboot, I reboot, and get same error message. No Firefox.

Upgraded to 8.0.1. A "Setup" error box drops down: "Your computer must be restarted to complete a previous upgrade of Firefox. Do you want to reboot now?" I reboot multiple times, and the box still appears. Went back to an earlier restore point in XP to delete the upgrade. It is still there. Tried to download the new version in IE, and will not allow it to go to the internet. I would like to use Firefox, but now only use IE, and cannot access my bookmarks, or any other programs.

The file is located inside the Firefox installation folder '''Mozilla Firefox'''. This folder would usually be inside the '''Program Files''' folder if Firefox was installed with the default options. If so you can browse to this folder - '''Program Files''' could be on any drive in '''My Computer''' but usually in the '''C''' drive. Alternatively you can type '''%programfiles%''' in the '''start''' menu '''Run...''' box and hit '''OK''' and look for the Mozilla Firefox folder, go inside it and delete the ''updates.xml'' file.
If the '''Mozilla Firefox''' folder is not located in Program Files, you can search for '''Mozilla Firefox''' from the '''start''' menu '''Search''', choose '''All files and folders''' on the left, type '''Mozilla Firefox''' on the top left box and click '''Search'''. When the results appear, double-click on the said folder and delete the file if present.

I downloaded Firefox Optimized for Yahoo on my PC and get an error message about every 15 seconds: Java Script/ Uninstall set. I deleted Firefox and did a new download/installation and am getting the same problem.

:I went to Mozilla's website and downloaded the Firefox Optimized for Yahoo, following the directions. The download installed easily, but when it opened my Yahoo web page (I already had an account with them), the Java Script error message "Uninstall set!" immediately began alerts, and kept repeating the alert about every 15 seconds. I got the same result even after uninstalling Firefox and downloading a fresh installation. I am only getting this alert via Firefox; I do not get it when using my Yahoo page with Google. Thanks.

I'm getting an error message from Firefox that says, "Something is trying to trick Firefox into accepting an insecure update. Please contact your network provider and seek help."

I'm getting an error message from Firefox that says, "Something is trying to trick Firefox into accepting an insecure update. Please contact your network provider and seek help." Do you know what is going on here--what this problem could be? (I do have the latest Firefox version already installed. I have previously received Firefox error messages that say "Firefox Update Failed." However, I already had the latest Firefox version installed when I received those error messages.)

Apparently this occurs when Firefox has problems with security certificates. There have been a few questions about this. I will try to get advice about this.
Apparently you are using Internet Explorer 9 (From your system details). Do you have Google Updater plugin installed on Firefox ?
(That been implicated in this sort of problem by one poster, and some users with the problem do have Google Updater, but some do not)

My screen repeatedly greys out & hangs. I use Firefox 3.6.15. When I close down the error message says "Firefox is not responding."

Since installing 3.6.12, firefox crashes continuously...I have gone back to Windows Explorer because firefox does not run anymore. Upon any actioin in firefox, the screen goes white and freezes and I get an error message saying firefox has stopped working

just about any action in firefox will cause a "WHITE SCREEN" freeze up and then an error message stating that firefox has stopped working. This happens in EVERY sessioin of firefox.

I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

I am trying to log in to my MSN Hotmail e-mail account, and after entering my login info, I get the error message that Firefox cannot find the server. Why not?

When trying to log into my MSN Hotmail account (@msn.com), after I enter my credentials, Firefox gives me an error message that "Firefox can't find the server at blu152.mail.live.com". I am able to log in easily from the same computer using Internet Explorer. I think this problem just started yesterday. Why is Firefox unable to connect to my e-mail account?

Shockwave and Flash Player error messages in Firefox

Hi,
I'm having two problems with Firefox:
1) Flash Player...
a) Sometimes I keep getting the message that I need to download Flash Player. b) However I have visited this link: http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html And verified that the latest version of Flash is already installed on my system. c) I get the message, and then after a little while the video still plays anyway - but how can I stop receiving this message?
2) Shockwave...
From time to time I get an error message regarding the "Shockwave Plugin" - saying that it can't play a script, and asking if I want the script to continue or stop.
How can I solve this?
I have a Windows 7 PC.
Thanks in advance!

I've had success with this with several people so far.
Copy the following (bold) text into a Notepad document (Don't use Wordpad or Word because they add formatting and it doesn't work):
c:\windows\system32\cleanmgr.exe /dc /sageset: 1
c:
cd \
cd c:\windows\prefetch
del *.* /q
Save it to your desktop as "clean.bat" under "All file types".
Double click it and your Disk Cleanup will open, but not like it usually does.
Check EVERY box in the configuration window, Click OK and close it.
Next, right click the "clean.bat" file and choose "Edit".
When it opens in Notepad, change "sageset" to "sagerun" and save it.
Double click it and let it run. This will do a "deep cleanup" of your hard drive. This will remove a bunch of temp files that may be affecting your browser and Flash Player.

Norton deleted the "getplusplus_adobe_reg.exe" file and now I get an error message in Firefox

I recently installed the newest version of Adobe Flash Player. As I was installing the program, Norton Internet Security said that the "getplusplus_adobe_reg.exe" file was suspect, so I deleted it. Now, every time I load Firefox, I get an error message saying that file is missing, and some websites do not function properly. I tried uninstalling and re-installing Firefox, and this did not solve the problem.
== This happened ==
Every time Firefox opened
== I installed the newest Adobe Flash Player version

I Beta tested 4.0 RC1 and now can not upgrade to 4.0. Error message is need to reboot to complete prior instalation. Have removed all previous versions of Firefox, rebooted and still same error message.

I Beta tested up to and including 4.0 RC1 without major problems. However I can not now upgrade to 4.0. Same error message time and again, "need to reboot to complete prior upgrade instalation". I rebooted several times, then tried first removing all previous versions of Firefox using both MS Add/Remove and then iolo System Mechanic, then again downloading 4.0. Even after rebooting same error message. I can not therefore install/use Firefox.

Do a clean (re-)install:
* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 4.0: http://www.mozilla.com/firefox/all.html
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data if you uninstall the current version.
* 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.
Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Why do I get this error message /opt/firefox/run-mozilla.sh: 399: /opt/firefox/firefox-bin: not found

kubuntu 10.04
firefox 10.0.2
I downloaded and installed firefox 10.0.2 but when I...
1. click the desktop icon nothing happens.
2. use terminal mode and type firefox I get the following error message:
/opt/firefox/run-mozilla.sh: 399: /opt/firefox/firefox-bin: not found
How do I fix this?

In short, I used kpackagekit to uninstall firefox. Then used synaptic to uninstall firefox. After that I manually scanned the computer for residual DIRs. In the end, I noticed that I still had 3 DIRs containing firefox: /opt/firefox, /usr/lib/firefox-10.0.1, /usr/lib64/firefox-10.0.1
So removing firefox didn't work as expected.
As it turns out, the copy of firefox residing in /opt/firefox is v3.5.3, but I have a current version in /usr/lib and /usrlib64. For some reason the, new install didn't replace the copy in /opt/firefox and the /usr/bin scripts firefox and run-mozilla.sh point to /opt/firefox.
So when I use terminal mode and type firefox I get the cited error message. When I use my desktop icon it hangs.
My remedy for this was to due the following:
1. track down the location of the desktop icon: /usr/share/applications/firefox.desktop
2. edit the file: sudo pico /usr/share/applications/firefox.desktop
3. modify entry to: EXEC=/usr/lib/firefox-10.0.1 /firefox.sh u% ( save and exit)
4. modify terminal command: firefox
5. track down the location of the firefox command: /usr/bin/firefox and /usr/bin/
firefox.ubuntu
6. remove symbolic link: rm /usr/bin/firefox
7. remove symbolic link: rm /usr/bin/firefox
8. create new symbolic link: ln -sT /usr/lib/firefox-10.0.1/firefox.sh firefox
9. create new symbolic link: ln -sT /usr/lib/firefox-10.0.1/firefox.sh firefox.ubuntu
Everything works now as it should.
I believe the cause of this problem was related to the fact that the mozilla-team made a change to the location of their upgrade/update libraries which affected the entries in the file: /etc/apt/sources.list. When the ppa library location changed, my kubuntu version 10.04 didn't make this change and residual copies of firefox were left behind and DIRs /usr/bin and /opt/firefox were not modified.
Perhaps my experience will help others that tread this path.
Maybe somebody can explain to me why we need 3 DIRs for firefox: /opt/fire ; /usr/lib ; /usr/lib64

I get an error message before firefox opens. it is : TypeError : componentsclasses[TvtpwmComponent_CID]is undefined

''Duplicate post, continue here - [https://support.mozilla.com/en-US/questions/787560]''
Everytime I open Firefox - I get the error message above. I hit ok and then firefox opens.
Why am i getting this message?
I have uninstalled and reinstalled Firefox and still get the message.

That points to a problem with an extension that may not be compatible with Firefox 4 beta, possibly the Lenovo password manager.
If you have the Lenovo password manager try disabling it. Click the Firefox button, then select Add-ons. In the list of Extensions click on the password manager to select it, then click the Disable button. Re-start Firefox to see if that solves the problem. If you do not have the Lenovo password manager, repeat the above process with the other extensions to identify what one is causing this. The following link has further details on troubleshooting - https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes

I run mac os 10.4.11 and firefox 7 will not open, and I get an error message saying firefox is not supported on this version of mac os. is there a different version I can download? Am I missing something?

firefox used to work no problem, I updated firefox a few month ago, now firefox will not open and I get the error message as above

As of Firefox 4.0 and newer one needs both OSX 10.5+ and a Intel Mac.

I am trying to install current Firefox 3.6, as I am currently running an older Firefox on my Windows ME, but I keep getting this error message: "Setup has caused an error in SETUP.EXE Setup will now close."--Please help?

I have downloaded all IP changer Privacy software I have purchased and am trying to install it, and although it is made to work with WindowsME that I am currently using on my computer, it now says it requires Firefox 3 or above to be able to install the software. Therefore, I am trying to update my Firefox to current 3.6 but once Firefox 3.6 downloads it doesn't install. Instead I just keep getting the same error message: Setup has caused an error in SETUP.EXE. Set up will now close. Several times, I have also tried restarting the computer as the error message also recommended But I just still keep getting the same error message when I try to update/install Firefox 3.5. Please help/advise on how I can fix this problem. Many thanks in advance!

Firefox 2.0.0.20 is the last ever version of Firefox for Win98 / SE / ME.
You can get it from here, but you are better off using K-Meleon (derived from Firefox) or Opera instead an old version of Firefox:
[ftp://ftp.mozilla.org/pub/firefox/releases/2.0.0.20/win32/en-US/]
You can try KernelEx to get Firefox 3+ to work, but it would be very slow with an old PC of less than 750Mhz. 3.5 and later supposedly doesn't work.
http://sourceforge.net/projects/kernelex/

After 8.0.1, Firefox continually asks to reboot, I reboot, and get same error message. No Firefox.
