How to reset firefox profile if it crashes on start (also safe mode)

Hello,
I need to know how to make Firefox do a profile reset when it crashes on start even in safe mode. It starts fine with a new profile.
I had this before today, and then after the 3rd crash report send, a popup offered me a solution to reset my profile while retaining the most important settings. I tried that option and it worked. But I could no longer sync my password with the new sync because of a master password set. I find this a show stopper, so I did a profile restore (mozbackup), I wish I didn't have.
I now have the same problem again with Firefox crashing, but it no longer offers the popup with a solution by trying safe mode (i did manually doesn't work) or resettting the profile.
I need to know a command line switch the make Firefox reset the profile while retaining the important data or how to force it show the pop-up.
Thanks a lot, I'm really pulling my hair out over this and need my Firefox experience back!
Thank you
Regards

Note that a profile created via a reset still can carry over issues because some data is recovered automatically.
If you use the Profile Manager then you get a completely clean profile and if that works then you can copy files yourself to the new profile or possibly try to identify what is wrong and repair your previous profile.
You only see button to Reset Firefox on the "Help > Troubleshooting Information" page and in the Safe Mode startup window if you use the profile that is marked as Default=1 in the profiles.ini file (Profile Manager).
If you do not have the "Reset" button then either use the Profile Manager to create a new profile or use the Profile Manager to start with the current default profile to get the Reset button in Firefox.

Firefox crashes at start in Safe mode - On ONE user account ONLY

Firefox crashes at start in Safe mode - On one user account on PC only
I have done everything on Firefox crash checklist
No '''Report ID''' since no start.
So no nothing in further support? See below

Figuring out the cause of a crash can be difficult. If you've tried the steps above and can't get Firefox to stop crashing, the steps below will show you how to collect information about your crash so our volunteers can help you.
1. In the Firefox Location bar, type about:crashes and hit Enter. A page listing submitted crash reports will appear. '''NO START so no Firefox Location bar'''
2. Right-click on the latest crash under Report ID and choose Open Link in New Tab. '''NO START so NO Firefox Report ID and not possible to choose Open Link in New Tab'''.
A tab will open to a page on crash-stats.mozilla.com, saying that "Your report is being processed". When it is finished processing, your report will load. '''NO START so NO Firefox Report ID and NO report will load so dead end and no help or support possible'''
3. Click this special link to ask for help with your crash.

Hi Max,
Congratulations, at least you made a stab at solving the problem. I think a lot of users used to glance at that KB article ([[firefox crashes]]) and give up trying!
Hopefully the crash instructions will be further modified soon, (some of us consider the following is an [/kb/Firefox%20crashes/discuss/1855 omission] that needs correcting) have a look at this article for an explanation of how to get the crash ID from your OS even without using firefox:
* http://kb.mozillazine.org/Breakpad#Location_of_crash_reports
The XP OS is likely to use smoke and mirrors to make it look like you have a totally
separate installation of firefox for each account, but normally you have the one set of (most) program files, and then for firefox separate [[profiles]]. So this indicates the problem is likely to be in the profile of the problem account, or down to a plugin, malware or other issue relating to that account. (I note you have already scanned for malware with MSE, that should detect a particular trojan that is a top cause of firefox 6 crashes)
If you create a new clean profile in that account hopefully it will solve the crash problem, you can then address the issue of copying settings, bookmarks. passwords etc back. BUT before attempting that ensure that you disable all plugins, ([[safe mode]] does not disable plugins) if you have not already done so. Some plugins may not show up in Firefox's list, you may need to look at the OS program lists.
I note you mention banking, a particular utility ''IDvault'' (I think Comcast supply it) has been causing crashes. Are you using IDvault ? (IDvault should be fixed soon bug684748; version 1.0.627 may have been fixed, but standalone version 5.9.627 has not yet been fixed )

Upgraded to 6.0.2, now get "Firefox had a problem and crashed". Starting in Safe Mode does not help. Now what?

Not sure what version I was running, but it worked fine but I have not been able to get it running again. I have uninstalled and reinstalled with the same results. Have followed the help pages to the point of obtaining the Crash Report... now what?
I did notice the CR seems to think I am running Windows XP but I am actually running Windows 7 (64 bit).

That gives Firefox 6.0.2 Crash Report [@ nsHttpHandler::QueryInterface(nsID const&, void**) ] https://crash-stats.mozilla.com/report/index/d2eddeb0-5845-4c72-987a-ad0282110917
Unfortunately that is not really getting anywhere yet, you could become the first person to file a bug about that particular crash, but that takes a bit of time and testing.
There is a known problem causing firefox 6 to crash and that is the use of IDvault, that can give more than one crash signature, the software developers regarding ID vault are WhiteSky, and are expecting to release a fix in a few days (if they have not already done so)
Have you tried
* using firefox's [[safe mode]]
* disabling all plugins
Does that help, either by preventing crashes or giving another recognised crash signature. You should also ensure all software is up to date, before trying adding extension software back.
The other common cause of crashes is malware, that includes a particular Trojan that is now known to crash Firefox 6. Check out [[is my firefox problem a result of malware]] you will need to do scans using software or sites with up-to-date scanning software, if you do scan for problems say what sites or software you used and the version of software used. Downgrading firefox versions rarely helps with crashes, it may help with the one specific trojan, but the security risks would then remain, potentially causing even more problems because the browser no longer crashes.

I cannot keep it from re directing to various unwanted sites... How do i fix this. Not going to start in safe mode every time! FRUSTRATED

After updating firefox,, i keep getting redirected almost 100% of the time.. I have attempted to fix this issue but i do not want to delete and redownload ff and loose all my saved info.. passwords etc. there has to be an easy fix for this.. If not.. i will start using another browser!!!!

Sounds like a Malware infection on your PC.
Install, update, and run these programs in this order. They are listed in order of efficacy. '''''(Not all programs detect the same Malware, so you may need to run them all to solve your problem.)''''' These programs are all free for personal use, but some have limited functionality in the "free mode" - but those are features you really don't need to find and remove the problem that you have. 
''Note: If your Malware infection is bad enough and you are mis-directed to URL's other than what is posted, you may have to use a different PC to download these programs and use a USB stick to transfer them to the afflicted PC.''

Firefox crashed and now will not start. Cannot create new profile or start in safe mode because Mozilla Crash Reporter appears and will not restart.

Browing the web, Firefox crashed. Typical "this is embarrassing" window appeared and I could choose to restore or start new session. I tried to restore, and nothing happened. Mozilla Crash Reporter appeared, the option to quit Firefox seems to work but restarting just brings back the Crash Reporter. I tried uninstalling and reinstalling Firefox, but Crash Reporter persists. I tried looking through your articles on crash on startup, but I cannot open Profile Manager, nor start in safe mode, nor anything else, with that Crash Reporter popping up. I can't give you a crash ID as I can't type anything into Firefox address bar if I can't open the program. I'm running Windows 7 starter edition on a netbook. Honetly really only use Firefox on this machine, so help would be appreciated! Thanks.

Maybe you did't understand my previous statement. There are no crashes in FF 3.6, There is no previous evidence FF 14 was ever here, I completely uninstalled all trace of Firefox, no app data, no preferences, no cache. I will upgrade to FF14 so I can send IDs,
so here ya go.

After updating Firefox, it wants to start in safe mode, when you click reset & restart it starts and runs fine, how do I make it stop opening in safe mode?

I recently updated my Firefox to 3.5.9 for Google pack, after doing so Firefox would only open in safe mode. So I started in safe mode that one time. Everafter, when starting firefox it always opens a dialog window about safe mode, I click the option to reset the toolbars and restart, and it starts normally. I'd like to make it stop opening with this dialog, and just open normally without asking about safe mode.
== This happened ==
Every time Firefox opened
== I updated Firefox

See: http://support.mozilla.com/en-US/kb/Firefox+is+stuck+in+Safe+Mode
Your Firefox 3.5.9 is 2 versions behind. The current version is Firefox 3.5.11 which includes several security updates. In addition, support and updates for the Firefox 3.5.x series is planned to end in August 2010. Consider upgrading to the latest version Firefox 3.6.8:

When i start in "safe mode".... no "reset" option box appears...how do I fix this?

My icons have disappeared from my bookmarks toolbar. Yes there are icons listed under toolbars/bookmarks..they just stopped appearing on the toolbar icon
********** PLEASE READ REST OF QUESTION BEFORE GIVING PRE-SET ANSWER ***********
As instructed I restart in safe mode (hold shift key down while starting firefox) in order to "reset" my bookmarks.
It does restart in safe mode, but no "Firefox Safe Mode" dialogue box appears..so I cannot reset the bookmarks toolbar using the "reset toolbars and controls" option.
*********THIS IS THE PROBLEM....I do not get the "Firefox Safe Mode" dialogue box when I start in safe mode!!
I have also tried disabling all my add-ons manually....and restarting Firefox no success
I have also tried ....<Help/restart with Add-ons disabled> ...no success
I have also tried <run/firefox -safe-mode> in the run box entry area form the windows start menu..no success.
NOTHING works..I cannot get the safe mode dialogue box that gives me the option to "reset toolbars and controls"
Please let me know how to solve this problem.....
Thanks
Traver

Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible.
*Firefox menu button > Options
*View > Toolbars (press F10 to display the menu bar)
*Right-click empty toolbar area
Use Toolbar Layout (Customize) to open the Customize window and set which toolbar items to display.
*check that "Bookmarks Toolbar items" is on the Bookmarks Toolbar
*if "Bookmarks Toolbar items" is not on the Bookmarks Toolbar then drag it back from the toolbar palette into the Customize window to the Bookmarks Toolbar
*if missing items are in the toolbar palette then drag them back from the Customize window on the toolbar
*if you do not see an item on a toolbar and in the toolbar palette then click the "Restore Default Set" button to restore the default toolbar setup

How do I fix this? "Firefox is unable to start correctly (0xc0000056)" I can't start in Safe Mode, either.

My Firefox does not open, at all. When I try to open i get the message that says "Firefox is unable to start correctly (0xc0000056)". I have tried to run the Firefox crash report, which also does not run. I'm unable to start in safe mode, also. All I get, is the above message...nothing else.

I'm not using that extension, so I do not know which files are used in addition to sessionstore.js and you need to check the profile folder yourself for suspect files.
This can be a problem with the file [http://kb.mozillazine.org/sessionstore.js sessionstore.js] in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder] 
Delete the files sessionstore.js and sessionstore.bak and any existing files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js .
See http://kb.mozillazine.org/Session_Restore

After upgrading to Firefox it now starts in safe mode and none of the options make any difference. What is wrong and how do I fix it?

A few weeks ago, I updated to a newer Firefox (I can't figure out how to find the version) and now FF starts in safe mode with a list of change options. None of them change anything. What do I do?

I've used Firefox for 5 years, and the crashing now is the worst it's ever been. I hope they get a fix soon, I've just reverted to Chrome... ARGH

If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Firefox 3.6.3 crashes at start-up

Firefox 3.6.3 crashes at start-up. I'm very frustrated with Firefox. I've researched through out the forum posts and tried everything I've found about FF not starting. A previous version of FF was running OK then one day when I tried using FF again and it now crashes at start-up. It will not start period. If I didn't need FF for this one particular application then I would just use another browser. I've been looking for a solution for this problem for many many weeks. Someone please help.
Computer is running Vista
Some days I think it would be less painful to beat my head against a brick wall then to deal with computers.
please help if you can,

FF is crashing on my computer with only one tab open and is running slow.....pauses for about 30 seconds when I close FF. Annoying.

Firefox crashes on startup, including safe mode.

Sometimes, for about an hour/two hour block, Firefox (and Thunderbird) while crash within a few seconds of starting up. This includes starting in safe mode, and often before I can attempt to restore or start new session. Often it will work fine, but sometimes I will click a link or attempt to go back a page and the pinwheel will come up for a couple minutes then it crashes, and will do so for the next couple hours. I've re-downloaded Firefox, it still happens. Only Plug-in that's out of date is Silverlight, the rest are either up to date or unknown. What can I do?

Firefox crashes constantly even in safe mode

Crashes constantly even in safe mode.
Have updated firefox and plugins.
Have run malwarebytes and superantispyware.
Crashes while surfing with no discernible pattern and then often crashes once or twice on restart of firefox.

hello olesker, it was initially thought that this kind of crash as contained in your crash id was already fixed in firefox 11, but obviously it's still around - the bug got reopened and will be worked upon by mozilla developers on a high priority.
