Firefox will not open up after i restored to default settings

i recently restored firefox to default settings on my profile on windows xp computer now firefox will not load on my profile but does on my fathers profile.whats up???????????

Hi jonbeme,
Thank you for your question. I understand after you reset Firefox, that Firefox will not open up on one of the accounts on this computer.
This is what happens when Firefox is Reset [https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems].
To test to see if the problem is the profile, use the Profile Manager to create a new profile. [[Use the Profile Manager to create and remove Firefox profiles]] If the problem goes away, you can then move your bookmarks and other important settings into the new profile.

Firefox will not open now - I just updated my privacy settings, and cleared cookies - what happened?

I changed the privacy settings on Firefox preferences, including clearing cookies, history and cache, and now Firefox will not open at all. It said it had to restart after one of the privacy changes, but it didn't and now won't open by the dock icon or thru applications. What happened, and how can I correct the issue to start using Firefox again? Thanks.

Hello,
Try start in Safe Mode:

Firefox will not open even after update or in safe mode using windows button + R

Tried solitions given on site using IE. Firefox will not start at all, did latest update and tried safe mode start.
Only get box stating it has encounterd a problem and crashed. I only use firefox and have so many bookmarks I really don't want to uninstall and start over.

We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.
#Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
#In that text field, enter %APPDATA% and press Enter. An explorer window should open.
#From that explorer window, double-click on the ''Mozilla'' folder, then double-click on ''Firefox'' and then on ''Crash reports''. Double-click on ''submitted''.
#Now, you should see a list of files that contain reports. Go to ''View'' > ''Arrange Icons by'' > ''Modified'' to get the most recent files at the top of the window.
#Open the most recent 5 files with a text editor and copy the IDs.
#Paste each ID with '''bp-''' into the reply window on the forums.
Thanks in advance!

Firefox will not open pdf files & changes the options/applications settings?

At first, with default settings, Firefox would not open pdf files & came up only with a blank screen & no file reference. Going to options/applications & changing the default to a new installation of Adobe Reader still brought up a blank screen but this time with the file ref. Oddly though, attempting to open any pdf file would then change the setting under applications back to Use Adobe Acrobat (in Firefox). But this doesn't work. So what do I need to do to get Firefox to open pdf files correctly using Adobe Reader?

See if either of these support article help you.

Firefox will not open saved desktop bookmarks, it always defaults to home page, why is that?

I like to launch Firefox by clicking on desktop shortcuts I have saved (bank, Netflix, Gmail, Amazon, Yahoo, eBay, etc...). With Firefox 29 any desktop shortcut now opens to my home page, Google. If I choose open to a blank page in the options, then all of my shortcuts open to a blank page.
In Firefox 28 all of desktop shortcuts worked just fine. I like being able to start Firefox on a specific page. Now it looks like I can only open to my home page or a blank page. This is terrible!!! I have tried creating new desktop shortcuts from Firefox 29 and I get this same results. Really terrible.
I can deal with the interface (which I really do not like now) but this simple lose of how I like to start Firefox is going to drive me away. Please fix or explain to me how I can launch Firefox from a shortcut and have it open that web page. Many thanks!

Sorry didn't work. I am using MacOS 10.6. New shortcuts created in FF29 have the same problem. If FF29 is not open, clicking on the shortcut opens FF to my default home page, never to the shortcut URL I clicked. For example, clicking an Amazon.com shortcut I just dragged to the desktop, then quitting FF29 and clicking the shortcut launches FF29 to my Google home page. If I change my default browser to Safari all of my desktop shortcuts open Safari to the right page. Chrome had the same problem but I couldn't stand Chrome so I don't care. This is definitely a FF29 problem.
I am really attached to FF in general and this is not a deal breaker, just a huge annoyance. Again, thanks for any help.

Firefox will not open again after crashing

Firefox crashed and brought up the Mozilla crash reporter. When I tried to restart firefox it just brought up another crash reporter and so on. I tried restarting my computer and it did nothing. When I look at the troubleshooting on this website it tells me to look in my menu bar, but I can't even open Firefox to get to that menu. Then it sends me to firefox won't start, and when I click on the part of that page about it crashing, it sends me in a circle right back to the page which told me to check my menu bar. My firefox also recently auto-updated.

Have you tried running Firefox with all add-on disabled (aka. safe mode)? Look in your start menu, there is an entry called "Firefox (safe mode).

Firefox will not open. After clicking on it, it loads and then nothing happens. Ive tried to download the latest version but is says i need to close firefox first. I cant find it open anywhere. Can anyone help?

Firefox will not open after attempting to upgrade to v5, sys restore didn't help

Was running 3.6 with no problems, but trying to upgrade today apparently broke it. The upgrade failed for some reason (the old .exe is still the only one in the Firefox folder & I can't find any files newer than April 2010 in there), but no matter how I try to run it, nothing happens - Firefox will not open, period. I tried reverting to last week with sys restore, scanning for malware with Malwarebytes, but still nothing happens. I'm using WinXP 5.1 media edition SP2 (yes, it's been around a few years but it works for me). I'm now using Chrome which seems to run just fine, tho I miss all my plugins.

Hi lwhealon
try from Start > Run > and type to check 1 of :
firefox -safe-mode
"C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode '''or'''
"C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -safe-mode
(to enable the Run box in win 7 see: [http://blogs.msdn.com/b/tims/archive/2006/09/18/windows-vista-secret-3-bringing-back-start-run.aspx enable Run box win 7] )
also check if [http://kb.mozillazine.org/Firewalls Firewall] or/and other security software blocking firefox start (like ad-blocker, web-accelerator etc).
[http://kb.mozillazine.org/Kill_application With Firefox completely closed] (probably because you can not start it), open the [http://kb.mozillazine.org/Installation_directory application folder] (by default, C:\Program Files\Mozilla Firefox on Windows) rename firefox.exe to firefox1.exe, then double-click firefox1.exe. If Firefox runs without problems, it could indicate that your firewall is blocking Firefox.
good luck

Firefox will not open after unlocking Sempron

After upgrading to a new motherboard and unlocking Sempron processor, Firefox will not open. I have tried Firefox (safe mode) and rolled back to a previous version, but to no avail. It worked fine when I ran the Sempron 140 as a single core (even overclocked to 3.17ghz) on Biostar A785GE motherboard. I cannot find a crash ID to link to.

Maybe you restored to a version of Firefox that crashes or still have a virus problem.
(irrc some Firefox versions specifically had problems after Windows restores)
Follow up checking for malware and then try re-installing Firefox. I would also suggest you make a copy of your [[profiles|profile]] including all folders and sub files and put it somewhere safe as it may assist in restoring your bookmarks and information.

Firefox will not open unless I run it in compatibility mode (Windows XP SP 3), run it as an administrator, or launch it immediately after a reinstall (the reinstall thing only works once.) How do I fix this?

This morning, Firefox crashed. After this, when I click the Firefox icon, the hourglass appears and then nothing happens. Firefox does briefly appear in the task manager when I do this.
I tried rebooting. I tried reinstalling multiple times. (Firefox will run when I select "Launch Firefox" from the installer. Then the problem occurs again.) I tried safe mode. I have found that Firefox will work if I select Windows XP compatibility mode from the icon properties menu or if I run the program as an administrator. When I do this, Windows asks me if I want a program to be able to make changes to my computer.
I have noticed that a Windows Error Report is being generated each time Firefox will not open.

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 open new window after clicking on link

if I click on a hyperlink in an email message (Apple Mail) then Firefox will not open (if not running).
== This happened ==
Every time Firefox opened

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

Firefox will not open. Hangs at "connecting" stage. Non-responsive even to process shut-down via task manager.

Starting yesterday, Firefox will not open at all. It hangs at the "connecting stage." For hours. It will not shut down even using the task manager for applications or processes, and it locks up virtually every other application. I thought I managed to save an open Word document yesterday - it looked like a slow, but normal save during the Firefox hang, but the document was empty when I restarted my computer.
Even though my machine is not pentium 4 based, I tried starting using the Windows XP/M configuration, I downloaded and re-installed (over the top of) the existing version, I verified that no Mozilla processes were running before trying to start Mozilla, and tried creating a new profile. Absolutely no success. Every time (of the dozens) I have tried to start Firefox I have had to force a hard shut-down to get out of the application. I have now unpinned Firefox from my task bar because I keep forgetting and hitting it by reflex.
I am running version 11.0 (at least that is what I just downloaded - I am not positive what I was running yesterday). My system is Windows 7 Home Premium, Intel Core i3, 2.4 gHz, 4 GB RAM, 64 bit OS.
Next option is to restore to a previous version. If that doesn't work, I will uninstall and start over from scratch.

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.

I upgraded from 3.6.13 to Beta 4.0 and now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing.

I uninstalled Beta 4 and re-installed 3.6.13 now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing, I have been using Firefox for a long time but cannot resolve this problem can anyone help and give me a solution please. As I use Firefox as my web browser it is very frustrating.
The fact it will not uninstall appears to be something completely new as nobody I know who uses Firefox has ever encountered this in the past.

Did you check your security software (firewall)?

Firefox will not open ANY site. Wont work AT ALL. Nothing seems to be working.

Firefox will not open ANY site. It worked last night, but not today. I uninstalled it many times, didn't worked. It displays the screen that says "unable to connect" yet chrome and explorer both work. I have disconnected and reconnected a few times, restarted my laptop, neither of those worked either. I have also tried turning "safe mode" off after re installing firefox, but again, that did not work. I need help :(.
Although, before this, firefox was not letting me use voice recording sites or any site that let me watch television online. It would load the commercials, but not play the episode. It wouldn't even let me upload pictures to photobucket. However, it worked using chrome or explorer.

Looks like a bunch of people have this problem. Anyone got any ideas to fix this???

Firefox will not open at all. I only get the Mozilla Crash Reporter over and over.

After updating yesterday, Firefox will not open. I repeatedly get the Mozilla Crash Reporter. I've scanned my computer for malware, I've tried to open it in safe mode (it won't), I've completely uninstalled and reinstalled Mozilla, but nothing works. Each time I reinstall, I still get the Mozilla Crash Reporter. The program will not open at all.
I ran my crash ID. Here is the info: bp-eff196eb-ed21-45ee-83c6-e0fc42130123

hello, this crash is caused by Websense Endpoint security software that is running on the system. please try to install all the updates for this program that are available...
