Firefox will not install on XP, hangs after extract, setup.exe at 100% of CPU

Did full FF unistall, ran CCleaner, cleaned registry of any mention of FF or Mozilla, rebooted. Downloaded FF 21, 22 and 24, all have same problem: Install extracts all the files to C:\Temp\7Z..., then runs setup.exe, but setup.exe consumes 95+ of CPU for an hour, but does not install anything. Tried in Win XP Pro SP3 Safe Mode, same issue. Machine runs OK otherwise, can use other browsers w/o problem. If I kill the FF setup.exe, machine returns to normal w/o reboot. C: drive has ample space.
Also tried killing all unneeded services and programs before running install, but that does not help.
(It is not the machine from which I am writing this message, so the Automatically Add does not apply.)
Real puzzler!

?? How would you know that the machine had any plugins at all? FF was completely unisntalled and there is no pluginreg.dat file, no profiles, nichts.

Firefox will not install addons

After getting a new computer and installing Firefox 12 on it, Firefox will not install addons. The only way that I can get it to install anything is by downloading the .xpi file and manually installing it. Unfortunately, I cannot download the .xpi file to one of the addons that I need to do my work, so this is a problem. Does anyone have any suggestions?

Firefox will not install. I keep getting a message that I have to restart my computer in order for updates to a previous version can be installed.

Every time I restart the computer and try to install firefox the same message keeps appearing. I attempted to uninstall the earlier version of firefox using "programs and features" in windows but the same message came up and thus I was unable to uninstall using that method. I have used a third party uninstall program which appeared to delete all traces of firefox including registry entries but I still have the same problem.
I am now in the position of not being able to load any version of firefox. HELP

Same problem here. I installed version 4.0, then removed it and tried to install 3.6. Now no version Firefox will not install. I keep getting a message that I have to restart my computer in order for updates to a previous version can be installed.

Firefox will not open in Vista SP2 after installing software for a Brother MFC printer.

I have 7 computer network. All the machines are running Vista SP2. I recently purchased a Brother MFC 9325cw, and installed the printer/scanner drivers as well as a program called scansoft paperport on each of the machines individually.
I left out the some of the bulkier aspects of the driver package, namely the brother control center because it seems to eat up a lot ram at start up.
Since I have installed the printer driver on my computers, several of them will not open firefox.
I have tried re-installing firefox on one machine so far to no avail.
Next I will try to re-install the brother software. Has anyone else encountered this problem before?

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 will not complete the installation even after several attempts of rebooting the computer.

I downloaded the Firefox 9.0.1 upgrade but it will not complete the installation on my computer. Everytime I try to remove the program, it tells me to reboot the computer to finish the installation. After several reboots, the same error keeps coming up.

Try to run the Firefox program once as Administrator (right-click firefox.exe: Run as Administrator).
If that doesn't solve the problem then remove the Firefox program folder (C:\Program Files\Mozilla Firefox\) to do a clean reinstall.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 9.0.x: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible.
*Do NOT remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.
Remove the Firefox program folder before installing that newly downloaded 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.

Your bookmarks and other profile data are stored elsewhere in the Firefox Profile 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.

Firefox will not automatically load Tiscali and after I have loaded using START it will not access my e-mails on tiscali

Until I loaded the latest version of Firefox I accessed Tiscali without difficulty usong the Icon. Now it will not access the internet at all and I have to use Windows to access the internet. Tiscali then loads but i cannot access my e-mails and I get a message telling me I have 'undefined e-mails'. Windows Explorer works perfectly

Hi again,
Helps if I give the correct link ! <br/>The press shift button appears to still work, but the option to start in safe mode from the programs listing of a standard install I do not think exists anymore.
Safe mode will start from a command line, (or a shortcut) and in some circumstances you may need to enter the full path name on a command or shortcut detailed instructions are at http://kb.mozillazine.org/Safe_mode
Remember (at least at this stage) do not make changes when you get the options list, just click on the continue button.
If you think that RealPlayer is causing the problem you could uninstall that for now.
Firefox recent versions are 3.6 4.0 (and 5.0 in beta). There is some debate as to whether creating new profiles or re-installing Firefox is the simplest method of troubleshooting and solving some of these problems, personally I use multiple profiles and multiple versions of Firefox, and tend to forget the required procedures are less than straightforward. For now at least try [[safe mode]] again.
* see also Instructions for [[installing a previous version of firefox]]

Firefox will not open at all. After click the hourglass comes up and then goes away and nothing happens at all. Nothing will load past the desktop. I cannot get into firefox at all to enable anything or disable anything.

When i click on the mozilla icon on the desktop the arrow will spin (VISTA) and will then disappear. Mozilla will not enable or even pop up or anything. I am still looking at the desktop and not mozilla. I lick on the icon many times and nothing ever enables, still stuck looking at the desktop and no Internet. Not to bring up your rival, but IE will open half way and then say not responding and will freeze and i must restart the computer every time. I have to use opera now because IE and Mozilla will not enable and Mozilla wont even pop up or enable or anything...just the desktop and no net. ONCE AGAIN MOZILLA WILL NOT ENABLE, SO I CANNOT GO TO TOOLS OR ANYTHING.

I have exactly the same issue. After FF upgraded on its own to version 5, it won't open from start menu, taskbar, desktop icon, or even by pressing firefox.exe in program files directory. It does so by pressing a link at msn messenger, inside Outlook etc.
Disabling all addons, didn't help. Moreover, I can't start FF in safe mode or start profile manager (Start > Run> firefox.exe -ProfileManager).

Firefox will not install on my computer. It was previously running. Then just stopped. I uninstalled and tried reintalling and it looks as though it is installing then does not complete.

Ran multiple anti-virus/malware to rule out. Everything is good. Registry error perhaps. Pleas Help. Maxthon browser sucks.

The Installation File is downloaded. UAC is disable. I am running AVG Interner Security 2011. I disable all security and When I open the instalation file, it says extracting, and the staus bar goes to 95%. I then get the circular waiting icon, then nothing. I can see 3 Firefox related files in the Processes of the Task Manager.
Firefox Setup 1476K
setup.exe 2840K Firefox Installer
setup.exe 2864K Firefox Installer
This is not a result of trying to open the installer multiple times. Each time I end the processes before trying again.
I sincerely appreciate the help.

Firefox will not open or uninstall even after following instructions

iv tried uninstalling in safe mode but nothing works

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.

IE & Firefox will not install or play Flash

Hi All
I have come to the end of the line with this ... for some
strange reason I can not install & or play the latest version
of Flash player which has rendered my Browsers useless, as far as
playing videos are concerned ... I have done the following :-
1) I E .. I downloaded the latest uninstall flash from the
adobe site .. re-booted tried to re-install the latest flash
when I click a video link on the browser I get the ( you do
not have the correct version of flash player click here etc etc ...
so I do it all over again
2) I did the same above with Firefox but when I click the
video page links I get a white background where the video should
occupy the space & play, it is surrounded by the text that
accompanies the story ( that bit is OK )
I have lowered the security settings on IE .. I have
un-installed re-booted .. re-installed .. turned OFF firewalls etc
etc with no way out ... I do now need some help with this ... I
have another machine on my network that works without any problem
... any more info I can give I am happy to supply
Regards
Corrie

System: Win7x64
Turn off ZoneAlarm.
“Run as administrative” Firefox.
I then went to the following install page which works:
http://www.adobe.com/software/flash/about/
It installed.
The following install page does not work:

The following thread discusses the problem with http://get.adobe.com/flashplayer/ download.

With so many Firefox users, Adobe needs to fix the http://get.adobe.com/flashplayer/ download for Win7 users.

Adobe 10.1.7 will not close in task manager after you exit the program. High cpu

Hello,
Updated to 10.1.7 and noticed that when you close the program an instance of acrobat stays open in task manager with high 50%+ cpu usage. Will not close at all unless you end task. if you open adobe again a new instance opens again consuming more cpu and cripples the machine with high cpu. This is on win 8 64bit machine. Had the previous release 10.1.6 working for some time on the same machine with no issues.
Thank you in advance

Identical issue with Acrobat XI Pro on Windows 8 Pro 64 bit. After viewing PDF file, upon closing Acrobat, a new Background Process starts called Adobe Acrobat (32 bit) uses 18% of cpu. I have left run for three to four hours and does not close. If I open another PDF file and then close, a second Background Process of Adobe Acrobat (32 bit) start, also using 18% of cpu. I was able to open a third PDF file and upon closing a third Background Process of Adobe Acrobat (32 bit) start, also using 18% of cpu. I did not try more. All three consume over 50% of processor and after an hour does not close. Fan and cpu begin to run hot so I manual End Task. I tried Repair Acrobat Installation command, did not fix. After searching forum used the Adobe Reader and Acrobat Cleaner Tool (http://labs.adobe.com/downloads/acrobatcleaner.html) to uninstall. Then downloaded Acrobat XI Pro from My Adobe account login. Reinstalled software. Issue gone, could not replicate even after several hours of trying. Then Checked for Updates. After updates installed, loaded and brought to version 11.0.3, problem returned as before. I have PDF files on both local drive and NAS, been able to recreate issue on both. In a PDF intensive environment, I was having to leave the task manager up and occasionally stop Background Process of Adobe Acrobat (32 bit) so as to keep processor usage and fan speed down, thanks to Goateye01 for the suggestion, I now leave Acrobat open and close the files, this way the background process hang does not occur. Additional Note, only able to create issue with standalone application, issue does not occur when in IE10 and viewing PDF files. Hopefully a fix or helpful guidance coming soon?

Firefox will not open at all, even after rebooting & re-installing - IE opens normally - what can I do?

I've used Firefox since version 3 - really like it compared to others.
This morning, after booting up Firefox wouldn't open. It worked when the PC was shut down last night. The eggtimer comes on briefly, then nothing. Internet Explorer works fine, as does Mailwasher (for email) and MS Outlook, so it's not an internet problem.
I'm running XP Service Pack 3 (no, really, still), with Webroot Secure Anywhere internet security.
I've tried rebooting - no effect
I've tried removing, rebooting, and reinstalling - no effect
I've tried launching it from a link within a mail message - no effect
I've tried launching it from the Start-Run line with the ~p option as in your FAQ - no effect
I've tried re-installing Adobe Flash Player, Java, Shockwave, etc..
The closest I've got to something to go on is when trying to launch a console from Webroot, when I got "Browser launch error 1073741819" - but this could be a Webroot error code.
I'm not sure what else to do - almost all your FAQ's assume you can get into the program.
The only thing I can think is that webroot removed a threat this morning, but I can't find any saved scan log as to what it was - clutching at straws, maybe that had something to do with it?
Maybe this is linked, but i'm having to write this on a different PC because the Mozilla webpages don't display properly in IE (all the other sites I can find display normally) So the installed plug-ins won't reflect what I have on the PC in question

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.

I need help. My Firefox will not stop doing this even after i reinstalled. I will shut down firefox and when I open it back up it shows the previous website.

Please Help. This is starting to anger me. I Reinstalled and everything.

You should update your outdated Firefox 13.0.1 version to the current Firefox 17.0.1 release.
I'm not sure what you mean.
Do you mean that Firefox always opens the web pages that were open when you closed Firefox even if you set to open with the home page or a blank page?
Make sure that Firefox closes properly and that there isn't a hanging Firefox or plugin-container process left in the task manager.
*"Hang at exit": http://kb.mozillazine.org/Firefox_hangs
*"Firefox hangs when you quit it": https://support.mozilla.org/kb/Firefox+hangs
Use "Firefox/File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") to close Firefox if you are currently doing that by clicking the close X on the title bar.
You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox Profile Folder that store session data.
Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox Profile Folder.
*Help > Troubleshooting Information > Profile Directory: Open Containing Folder
*http://kb.mozillazine.org/Profile_folder_-_Firefox
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

Firefox will not bring up any webpages after updating to v3.6.7 and then 3.6.8

Everything ran well in v 3.6.6. Today it seemingly upgraded to v3.6.7 and then a Mozilla web page strongly suggested upgrading to v.3.6.8. I did. Sometime after this Norton 360 v3 found some bad files and quarantined them and needed a reboot. After that reboot no web pages would work in FF. I followed the Norton 360 connection thread and that did not help. I also received a new router yesterday, but v3.6.6 worked fine today and IE works now, so I doubt that the router is the reason. Right now I would be happy to revert to 3.6.6 or else uninstall and try from scratch. I have tried a few reboots, but they did not help.

which is, I guess what you are talking about.
We will try it this afternoon, after school is out. However, as I said, our problem is not limited to Firefox.
Hmmm.
Firefox 4.0 and Safari 5.0.4 do not work.
Chrome and Omniweb both work, after 10 or 15 seconds.

Firefox will not install on my laptop

The latest update to Firefox (33) did not work. After download it froze up with a partial black screen. I have uninstalled and re-installed Firefox several times with the same result. Symantec possible issue has been eliminated. My laptop runs windows 7 enterprise. Until now, Firefox has always worked for me. Its Google Chrome for now.

Other users with this problem all had an embedded intel hd graphics card with an old driver present. in case this also applies to you, here would be a link to update the driver, which in turn should also address the black firefox problem.
