no extensions , no addons uninstalled thunderbird, deleted all TB folders then rebooted win safe mode and ran Malwarebytes - no malware, rebooted normal windows and downloaded fresh version of TB reloaded profile using mozback. Still the same TB loads showing 3 folders no inbox and should be 2 accounts. Change to safe mode in TB and all files are present and 2 inboxes
i am not losing data just can only see emails when in TB safe mode. What TB profile files could be contaminated?

I changed Java settings and now Firefox crashes as it opens, even in safe mode; how can I fix this?

I was trying to change settings to access the comments section of Slate.com. Right or wrong, I changed a Java setting from -1 to 2. The setting was in about:config and I believe it involved some sort of max. As I cannot open anything, I am not sure.
When I made the change, firefox crashed immediately, Every time I have tried to reopen, even in safe mode, it immediately crashes again and will not reopen.

Hi pternagy,
Sorry you are having problems.
For future reference. Those of us that mess directly with about:config soon learn how to recover from mistakes and what it is sensible to backup. Occasionally backing up your entire profile for instance can be useful and would have probably given you a quick solution of copying over the file from that backup.
*[[Back up and restore information in Firefox profiles]]
Ok on to the subject of trying to get Firefox back as it was:
Find your profile and the file ''prefs.js'' and rename that. (The renamed file is a potentially useful backup.) Firefox is then forced to regenerate the file and will reset your preferences to the default. You can then re open and use Firefox. Next try to get it back to normal.
Trying to manually edit the file ''prefs.js'' is normally a bad idea. However if it is a single pref change it may be possible to directly edit the prefs.js file (whilst Firefox is closed) to get everything back to how it was before . You have the renamed file to work with. Probably best to test all this out in a new additional profile then you only break additional test profiles not working profiles essential to Firefox.

My iMac only starts in safe mode few hours after upgrade to 10.7.3

After I updated to 10.7.3 on my iMac everything looked fine, but after few hours of activity everything except mouse cursor froze in a fullscreen app. No keyboard shortcut was able to force quit the app and only way was to turn the iMac off with power button. After restart login screen appeared and after I logged in the system froze while after the Skype started and I wrote few letters in a chat there. Again only power button worked, but this time I didn't even get the login screen, everything froze on the grey screen.
I searched web on mac book and found info about problems with update and solution via installing comboupdate. I managed to start in safe mode and installed the combo update. After installation system started and all worked fine few hours until screen froze again, the picture gor a bit corrupted (some "empty" squares appeared) and I had to use power button again.
Since that time my only way to get to login screen is safe mode (holding shift after restart), next reinstal of combo update didn't help. New install of lion runs correctly the part of instalation in the safe mode, than it restarts after while computer restarts and installation progress is shown, however the progress freezes nearly imediatelly and nothing happens for next hour.
If I boot from recovery partition it starts after relatively long time the system utility, but even here interaction is wrong as after every click I have to wait few minutes until something happens, so I was not able to really start some action there.
I can only take the iMac to sevis (sadly the 1 year warranty over) on monday so any suggestions what I could try till then to make it working again are very welcome.

So the result form Apple authorized servis was that both motherboard and graphic card need to be replaced (cost aproximatelly 1100$) and in addition they said there will still remain some problem with display which would cost additional 500$ to fix. Taken in account that there would be only 90 days warranty on new parts I decided to give up with the iMac. Very disappointing after only 1,5 year on machine that costed more than 2000$.
Recommendation from me after this experience - buy 3 years warranty if possible. I am personally very much looking forward for Mac Pro refresh. I don't want to be again in situation that if something breaks in my working machine I have no chance to replace it myself and can only expect very high repair costs. Untill new Mac Pros are out I'll suffer working on Mac Book Pro.

Having upgraded to Firefox 24 it will now not start at all after clicking on the icon. My OS is Windows Vista premium. It will start in safe mode.

Upgraded to Firefox 24 and now nothing at all works despite uninstalling and reinstalling it several times and losing all my bookmarks etc. However it does start in safe mode. At first I thought it was my security Norton 360 but after 2 hours in contact with them I'm still in the same position. When I double click on the Firefox icon I can see the cursor timing out and then it just disappears and nothing loads.
My OS is Windows Vista Premium and I am using Windows internet explorer at the moment.
HELP please!!!

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:
* [http://www.microsoft.com/security/scanner/default.aspx Microsoft Safety Scanner]
* [http://www.malwarebytes.org/products/malwarebytes_free/ MalwareBytes' Anti-Malware]

* [http://www.surfright.nl/en/hitmanpro/ Hitman Pro]
* [http://www.eset.com/us/online-scanner/ ESET Online Scanner]
[http://windows.microsoft.com/MSE Microsoft Security Essentials] is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

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

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,

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 )

Downloaded Firefox yesterday. Every time I open the Firefox browser, it starts in Safe Mode even though I have shut down and restarted my computer several times

I have Windows OS. I downloaded Firefox yesterday. Every time I open the Firefox browser, it starts in safe mode. I have restarted my machine several times -- Firefox still starts in Safe Mode. My favorites from IE copied to Firefox fine, and Firefox is now my default browser...it just keeps opening in Safe Mode.

I downloaded the toolbar. When I was done using the computer, I put it to "sleep." The next time I "woke" the computer and went to Firefox, the toolbar was gone. When I downloaded the toolbar again, I got a box in the upper left hand corner of the screen stating Firefox BLOCKED the toolbar, and did I want to allow it. There was NO option to allow always-it's just a one time deal. When I shut down for the day, I expected it to remain, but no-next time I fired up firefox, NO TOOLBAR. I pulled up Inbox dollars again, clicked on download toolbar, got the box stating it's blocking the toolbar, etc, etc, etc. Unless Firefox upgrades daily, or in some cases, several times in one day, I'm going to stick with my description that the toolbar magically disappears EVERY TIME I OPEN
FIREFOX!!!
I don't profess to be any type of computer whiz, I'm totally self-taught, and it's not beyond the realm of possibility that I'm doing something wrong. I've been using Firefox for about a week, so I'd welcome any help!

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.

Starting in Safe Mode - N500

I cannot seem to get my Lenovo N500 to start in safe mode.
I am running Vista Basic and after completing a number of upgrades I get caught in a loop.
I have gone to the MS site and they recommend doing a recovery but to achieve this I need top boot in safe mode
Any help appreciated

Try repeatedly tapping the F8 key on boot up.
If you get a text mode screen with options, choose Safe Mode.

Firefox is crashing at start up. tryed uninstalling it. andreinstall .still crashs at start up..but starts in safe mode...

firefox 3.6 runs great .but when i install 4 all it does is crash when it starts up.
did a full uninstall. and then deleted all firefox folders
then installed firefox onto a 2nd drive.. to see if that would help. stop it from crashing when it starts up.
but no go.
updated my vid driver.. still no go
it will start in safe mode.. so i tryed disabling all extensions and plugins. still firefox 4 just crashs when it starts up.
it would be nice. if .firefox crashed .it would just tell you why...............
if i missed something .hope some one can help..
Thanks
PS
i love firfox 3.6 .. but why would you put out trash like this. it will not even start up.
are you trying to be more like Internet Explorer.
crash.....crash....crash...
reinstalled 3.6 and stoped the auto updating for now.'''bold text'''

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")
* [[Troubleshooting extensions and themes]]
Your above posted system details show outdated plugin(s) with known security and stability risks that you should update.

You can find the old Flash plugin file NPSWF32.DLL in the plugins folder within the Firefox program folder (C:\Program Files\Mozilla Firefox\plugins\) and remove that file.
