I just downloaded Firefox & I cannot open it in normal or safe mode.

Nothing happens when I try to open Firefox.

Thank you but yes, I realise that. My question was however, how do I get Firefox to start up online automatically ( as it always has done in previous versions), without having to go to File and untick Work off line every time.
As a result of this unnecessary process, I no longer use Firefox as my default browser (just in case anyone from Firefox happens to read these posts!!)

Firefox 19 crashes on startup in normal and safe modes.

upon startup, ff19 crashes in both normal and safe modes. I've disabled all add ons and extensions.
XP Pro sp3.
It started crashing occaisionally, then increasingly more often, now, upon startup.
I tried reloading ff19.
I can't start ff with the -p command.

its not correct crash id.
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 hangs when opening Tools - Options, even in Safe Mode

I've just upgraded to Firefox 3.6.13. Prior to upgrading I removed all add ons. I went to Tools -> Options to check the settings and Firefox hung. I had to end it with Ctrl-Alt-Del. This happened several times. Then I started Firefox in Safe Mode and attempted to view Tools -> Options again. Firefox hung. It does not try to submit any crash reports (apart from the automatic Microsoft report that occurs when you end a program manually).
I can browse websites ok, open PDFs, view Flash, etc. I just can't view my options!

Thanks for the note about profile locations.
I deleted mimeType.rdf in my existing profile, still have the same issue - can't view Tools -> Options for the Applications tab, or download a file. Same goes for a new profile - the same issues arise.
Firefox never does crash, I can leave it in this hung state for hours (I left it in a 'not responding' state last night and it was still hung this morning).
I was going to add a screen shot to this post but Firefox hung when I clicked on the 'Browse' button. Perhaps this is an issue when FF tries to interact with my directory structure? Does that get us any leads on what's wrong?
FYI, I currently have my antivirus disabled & not running in the task bar just in case that was interfering somehow.

Can't open firefox, get error message: The instruction at "0x00000000" referenced memory at "0x00000000". The memory could not be read". Firefox won't open at all, not in safe mode or anything. Tried uninstalling and reinstalling, no good, tried creating

Cant' open Firefox at all, not in safe mode either, tried creating new profile, cant' get in to do that, tried uninstalling and reinstalling, switching off and on, nothing works. Get error: "The instruction at "0x00000000" referenced memory at "0x00000000". The memory could not be read."
== This happened ==
Every time Firefox opened

The solution is easy.
Install "Malwarebytes' Anti-Malware" free edition and use it. This program found malware in your pc. After that clean this malware. Finally instal Firefox again and enyoy it because this installation is correct and clean. Regards.

Firefox will not open (have tried "run in safe mode" and other alternatives)

firefox unexpectedly closed; i tried to reopen- no luck; rebooted computer and "add-ons" opened but firefox did no! now firefox trys to open for about 10 sec and then quits trying. i have no messages/promts or any kind of other indication that there is aproblem (other than the browser won't open). i am using google chrome to post this request. thanks in advance for any suggestions! bill crimmins

See http://kb.mozillazine.org/Browser_will_not_start_up
Did you check your security software (firewall)?
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 and the plugin-container process.

FireFox 4 Crashes When Started (Both Normal and Safe Mode)

When I open up FireFox 4 (both in normal mode and safe mode) it crashes within a few seconds. It is a fresh install of FireFox 4 but I also have FireFox 3.6 installed as well. The report that was given is:

1. You have a pre-release Beta 1 version of what will become Firefox 4 in like 5 or 6 months. Unless you are intending to test it for flaws and report those flaws to help in the development process, don't use it.
2. Did you create a new Profile for 4.0b1, and are you using that Profile with it? ''That isn't done automatically when you install 4.0b1, and those of us who have been doing the "testing" for many years consider a new Profile as the basis of doing out testing.''
[http://support.mozilla.com/en-US/kb/Managing+Profiles]
IMO, Mozilla is making a huge mistake by directly offering these beta versions to the general public.
Also IMO. if you want to play with 4.0b1, use the Portable Firefox 4.0beta version to minimize any conflicts with a currently installed version of Firefox, and to eliminate the need for creating a new Profile for 4.0 Beta #:
Download Firefox Portable Test to your hard drive and double click the '''FirefoxPortableTest_4.0_Beta_#_English.paf.exe''' file. The entire installation (including a new Profile for "Portable") will be self-contained in the \Program Files\FirefoxPortableTest\ folder and won't interfere with an "official" version that you already have installed. Your Profile will be in the \Program Files\FirefoxPortableTest\Data\profile\ folder.
The "down side" is that Firefox Portable won't launch if any other version of Firefox is already running.

Just downloaded Firefox 4, cannot print web pages, print is all skewed, looks like secret coding.

Tried to print a web page friendly receipt and then tried printing a web page, print is skewed, looks like some sort of encryption.

Installing nightly builds is not recommended for most people. If you install a nightly build you will get updates every day. Though the current nightly builds are stable, it is not unusual for them to be very unstable and at time unusable.

Firefox crashes when opened and the same in safe mode

We're Sorry
Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts.
To help us diagnose and fix the problem, you can send us a crash report.

Your Ask Toolbar is at least part of your problem. Someone may come along with specific removal advice; otherwise try the "Search Firefox Help" box above or Google.

Firefox crashes upon start up in normal and safe mode

Can't open firefox in either mode, it immediately gives me a crash report pop-up

Did you try to download FF10 with another browser and install it over your current FF version?

Just downloaded Firefox 6.0 and have restarted 4 plus times, but it continues to hang while launching. I cannot open new windows, change any settings, or do anything but Force Quit. I'm on Mac OSX 10.5.8. How do I get past this hang?

Long story short: Simply get CC for teams. At 500 bucks a year it's a steal and those 5 licenses in the base package (or was it 10 even?) cover all your computers, at least the 3 ones you mentioned. For system requirements refer to the individual product pages.

Do a clean (re)install:
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data when uninstalling.
* 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.
You can initially skip the step to create a new profile, that may not necessary for this issue.

Have you tried to run firefox '''as an administrator''' ?

I just downloaded firefox on my new computer. I cant find it.

I have a new computer with 8.1. I am learning how to use it.
I just downloaded Firefox and don't know where it is, or how to use it.
Can you help?

What program did you use? Start it, find and open the downloads
window (on some programs; '''''Control J'''''. If the program is listed
a right click may open a menu where you can find its location.
Also, go back to the web site and select like you want to do a download,
BUT at the window that tells you 'press to start', '''STOP!!''' Look at this window.
does it say where the download is going? If so, open that folder and see
if what you are looking for is there. Also, what is the file name of the
download? Open Windows Explorer to C: (or where ever) and search
for that file. This may take some time for large hard drives.

Just downloaded Firefox 4 on Windows Vista 32-bit and its not working at all.

So I just downloaded Firefox 4 on Windows Vista 32-bit, and it's not working at all. I open up Firefox and there is not tab bar, and all the command buttons are repeated 3 times, and are on 3 different bars. This only happens with Firefox 4 and not Firefox 3.6.10. Also, when I go the menu bar and I try to click soething, nothing happens. I'm not sure why this is going on. Help anyone? Here is a link to a screenshot of my browser.
http://img683.imageshack.us/i/firefox4y.jpg/

I have this too, but doesn't even startup now? I downgraded to the previous version and all is OK. I also have a 64 bit version of Vista and it seems to work "a-OK" on that machine.
Seems to me to be 32-bit issue.
Editing this post:
I just seen a possible answer...Do you have roboform installed (in the taskbar also)? If so, try disabling it or removing it and try to start again. I said above that I have 2 units and on the one (32-bit) I have Roboform installed and it crashes, but on the other one I don't...so go figure.
According to the report I read, if you upgrade Roboform it should be OK, although I have not tested as of yet...I am still at work...
Hope that helps...

Uninstall the Inbox Toolbar, following steps here:
http://toolbar.inbox.com/faq.aspx?faqid=2876&faqmod=WST_Install#1
Then retry opening Firefox.
You can also try opening Firefox in [[Safe Mode]] (use Continue in Safe Mode first).
If that works, reopen Firefox Safe Mode, but use the dialog option to '''Restore default search engines''' as shown at https://support.mozilla.com/en-US/kb/Safe+Mode#Safe_Mode_window and press the '''Make changes and restart''' button.
