Firefox will not run after System restore or running in compatibility mode for windows 98. How do I fix this? I already tried all other solutions on this site.

I was running Firefox fine just yesterday. I screwed up the registry a litle while removing an installed program completely, so I restored the system and everything appeared to work fine. I then decided to play an old video game, Return to Krondor, which was made back in 1998, so I ran the program with no other programs running in compatibility for windows 98. After finishing the game, I closed it and put the computer in hibernation mode. I come back today and firefox will not run at all. It is not running in the background and there are no programs running. There are no services running which could interfere with it. I think somehow Firefox may think I'm in compatibility mode still, but I have no idea.
I'm running windows Vista 32 - bit with an AMD 2.4ghz processor, 4gb ram on an Emachine computer. I have already tried system restore, restart, processes etc. Nothing works. I can still run Internet explorer and all other programs.

The person that I was assisting, has Windows 7 which has 64 bit system. Her browser was IE 10.
Was IE11 ever offered (or installed) via Windows Update?
Is her computer currently fully-patched at Windows Update?
Is Adobe Shockwave Player v12.1 (or higher) installed on her computer?
Is Adobe Flash Player v15.0.0.189 (or higher) installed on her computer?

After refomatting HDD, reinstalling Vista plus service packs, recovering files from Microsoft backup and installing new copy of Firefox 3.6, Firefox will not run. Have deleted all old M0zilla profile folders and reinstalled Firefox again to no avail.

After computer would not boot and could not be repaired, I reformatted the HDD, reinstalled Vista plus all service packs and updates, recovered files from Microsoft backup and installed new copy of Firefox 3.6. Firefox will not run.
I have deleted all old M0zilla profile folders and reinstalled Firefox again to no avail.
After intallation was completed, the automatic startup just placed a small box on the screen "Import wiz". This just sat there with no activity. After I closed this box, none of the Firefox start buttons would open the program -- just the blue rotating icon for about 2 seconds then nothing.

Hi,
Please try to rebuil the WMI repository.
For detailed information, please refer to the blog below,

If issue persists, due to sfc doesn't work, could you try to repair your system with the installation disk?
Best Regards.

Google earth will not run since downloading yosemite

google earth will not run since downloading yosemite

Do a backup.
Quit the application.
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library. Then go to Preferences/com.apple.Safari.plist. Move the .plist to your desktop.
Restart, open the application and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer one.
Thanks to leonie for some information contained in this.

Firefox will not run except on new download.

Firefox will not start under any circumstance from any shortcut, nor when started under Administrator or in safe-mode or with all apps disabled. It will start after a new download but only once. I cannot access profile manager from start/run, each time I get a 'Parsing error' message. I have tried basic removing and also removing complete with all profile details. I have performed re-starts after deletion and before and after re-installing. I have tried backdating the computer many times to different dates and the best result is an 'XML error' message on re-start attempt. Internet Explorer still works but frequently with 'Error on page' message. I have Mcafee installed but have had for years with no previous problems.

after downloading iTunes it will not run on my pc in order for me to install it.

Are you able to successfully download an installer if you use Firefox instead of IE or vice versa? (Firefox handles network/internet connections differently from other browsers, so an issue in IE can sometimes be overcome by using Firefox or vice versa.)

Firefox will not run on Windows 8.1

I have 3 pcs running 8.1 update 1. all run the same AV software ( Emsisoft). All are identical. However one machine will not run FF27-29. Windows tells me that " this app can't run on your PC". I have uninstalled and reinstalled using the stub and also by downloading a complete installer. Neither have helped.
Any thoughts?

FIREFOX WILL NOT LET ME DOWNLOAD A SCREENSAVER AND I AM MADD

i WANT A SCREENSAVOR AND FIREFOX WILL NOT LET ME.i GET A POP UP BOX PROMPTING ME TO SAVE A FILE AND THIS IS ALL GIVING ME A HEADACHE. ON IE I NEVER NEVER NEVER HAVE THIS PROBLEM, ONE CLICK AND I HAD A SCREENSAVER.I LOVE FIREFOX AND WILL NEVER GO BACK TO IE SO I AM PLEADING WITH SOMEONE TO HELP ME OUT. THANKS

What do you mean by 'will not let me download' ? Is the buy/download button greyed out ? Are you getting any error messages ?

New version (17) will not run after downloading and installing. Tried twice ...uninstalling between downloads but to no avail. Have re-installled v.15

this is really to report what occurred this morning.
since the update to v 17 Firefox would not run
d/loaded the new version twice (uninstalling between) but to no avail - the program would not open although Task Manager shows the process running.
have re-installed v 15 so I have a browser.
lack of a way to report such problems is a weakness which needs addressing

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.

Firefox will not run properly now

I really need help getting my Firefox to run properly. Earlier this evening I downloaded the epub reader addon from the Firefox addon website. After that I noticed my Firefox was using yahoo as the search engine instead of Google. I've tried the obvious set it to Google but it kept going to Yahoo. I also uninstalled the addon but it still kept searching on Yahoo. So I searched for solutions online. Then I tried the Help>Troubleshooting Information Restart Firefox. This when all the problems began.
Now every time I go to Google.com or search on the Google toolbar I get the This Connection is Untrusted message
Screenshot: http://imgur.com/BttGmGU
Also when I go to certain websites like the mozilla firefox add on website it will not load properly
Screenshot: http://imgur.com/oIz0XgE
Can anybody help me with this? I've tried the obvious options like uninstalling and reinstalling but my Firefox refuses to perform normally. Also I still have the old Firefox Data. Is there a way I can restore that data?

Check out why the site is untrusted (click "Technical Details to expand that section) and if this is caused by a missing intermediate certificate then see if you can install this intermediate certificate from another source.
You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.
*Click the link at the bottom of the error page: "I Understand the Risks"
Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
*Click the "View..." button and inspect the certificate and check who is the issuer of the certificate.
You can see more Details like intermediate certificates that are used in the Details pane.
If "I Understand the Risks" is missing then this page may be opened in an (i)frame and in that case try the right-click context menu and use "This Frame: Open Frame in New Tab".
Note that some firewalls monitor (secure) connections and that programs like Sendori or FiddlerRoot can intercept connections and send their own certificate instead of the website's certificate.

Firefox will not run a WebEx Meeting even though Java Script is Enabled! I am on 4.0, is this a beta version of FireFox? Are you going to Support Java anytime soon?

I am getting the following error after going in and setting up a WebEx meeting. I will not be able to use FireFox unless you get the ability to enable Java:
"Java Not Enabled
Meeting Center cannot be installed because Java is disabled in your Web browser. Please enable Java in your browser, and then click Set Up again. For instructions on enabling Java, refer to your browser's online help.
If Java cannot be enabled for any reason, you can download the manual installer and install it from your desktop by double-clicking the installer icon."
I enabled Java, added WebEx to all secure sites and performed every possible check known to man. This is on your end FireFox.
Do you have an ETA when 4.0 will support Java?

I will not pretend to know any answers to your problems, but I do wonder if you realise Firefox did decide to produce and support an Extended Stability Release, unfortunately this is NOT going to be based on Firefox 3.6. but on Firefox 10.
For those directly concerned with this see https://wiki.mozilla.org/Enterprise#How_to_Participate_and_Post

Firefox will not show a downloaded toolbar. It says it is installed but it will not put in on my toolbars.

I downloaded the ChaCha Guide Toolbar 1.2. It says it in installed and enabled, but it will not show up on my toolbar.
== This happened ==
Every time Firefox opened
== The first time I tired

You can retrieve the certificate to check who issued the certificate.
You should always do that to see if that helps to identify the problem (missing intermediate certificate or something else).
*Click the link at the bottom of the error page: "I Understand the Risks"
Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
*Click the "View..." button to inspect the certificate and check who is the issue.
If you can't add an exception, but get a pop-up with the error message then you can check the pref [http://kb.mozillazine.org/browser.xul.error_pages.enabled browser.xul.error_pages.enabled] on the about:config page and make sure that the value is set to the true (default).
See http://kb.mozillazine.org/about%3Aconfig

Firefox will not run - double click on icon, select icon and run/open, opening via start menu are all dead

Problem started yesterday (9/28). While in Firefox, bookmarks stopped working. Closed out FF and tried to reopen the program, and nothing causes FF to launch. Tried double clicking on the desktop icon, single click on the bottom status bar (on XP), right click on icon to open or run, trying via Start -> All Programs -> Mozilla and neither regular or safe mode would launch. Only thing that seems to fix the problem is a full restart of the computer. Tried downloading the newest version via Chrome. When I clicked to run the install, kept getting a message to close all FF windows, even though there were no FF windows open.

Check that you do not run Firefox as Administrator.
Right-click the Firefox desktop shortcut and choose "Properties".<br />
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
* Privilege Level: "Run this program as Administrator" should not be selected
* "Run this program in compatibility mode for:" should not be selected
Also check the Properties of the firefox.exe program in the Firefox program directory.
A possible cause is security software (firewall) 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 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.

You can install a portable Firefox (ESR) version to access websites that do not work with the current Firefox release.
