Firefox does not start when I click the icon. It has been working fine for over a year.


I have been running Firefox for over a year. This is on an HP laptop running Vista. This passed weekend, I got a message saying Firefox could not open a website. I closed the browser and shut down the computer. When I tried to restart Firefox the following day, I kept getting errors saying it could not open. I was short on time so I had to use MS explorer. This morning since I had more time I figured I would try to get it working. When I double click on the icon, I get the hourglass for a few seconds, but nothing happens. I went to Windows "Installed Programs" to see if there was a "repair" option but it will only let me uninstall. I do not want to lose all of my bookmarks, passwords etc.

I can still use Internet Explorer to download if I need to.

Additional System Details

You posted with an old Firefox 3.0.19 version.

You should update to Firefox 3.5.9 or 3.6 x version.


Question owner

OK I tried the suggestions but still No-Go I am using the laptop now with IE and it totally sucks. When I open FF I get a Windows message saying "Firefox has stopped working, Windows will close the program and notify you when a solution has been found" Like I believe that. It started the first time with a blank screen and the above message, I tried it again and my start page loaded then I got the message. Please help someone!

Hi there, does Firefox start in Troubleshoot Firefox issues using Safe Mode ?

Helpful Reply

Born2die! Brilliant. I am a desktop clicker and never knew Firefox had a safe mode. Thank You! I was unable to start in safe mode initially. The second time I disabled all of the Add-Ons and she started up just fine. I enabled them one by one hoping to track down the culprit but the problem seems to have gone away. BTW I am running ver. 3.6.8 (in response to cor-el's earlier post) and Firefox is in the process of downloading 3.6.10 (which I am starting to think may have been what caused this whole problem to begin with) Incidentally, whats up with all of the Java Console Add Ons? I have: Java Console 6.0.11, Java Console 6.0.13, Java Console 6.0.15 Java Console 6.0.17, Java Console 6.0.20, and Java Console 6.0.21 What are they? Do I need them? Can I uninstall them? Is this due to using Open Office? Also, .NET Framework 0.0.0 Should I uninstall it?

Correct me if I am wrong, but I think the Java Console comes with your Java installation. As far as I'm concerned, it is not important and therefor not required to be enabled in order for Java to work.

.NET framework is however a complete other story, best to ignore it.

I run HP Pavilion Windows 7 Home Premium desktop PC and I cannot get Firefox 3.6.13 (Kami knows when 14 is coming!) to even launch after numerous DLs, installs, uninstalls, reinstalls, uninstals, DLs, reinstalls. When I get to the screen that says launch FF now? I hit OK and then the spinning orb meaning working then poof it diappears and no FF screen at all! The same thing happens with Opera, Orca, Chrome and every other browser I try. I'm on IE8 64 bit-K&K

Ran out of room in last post. The only browser working is IE8 64 bit. I tried downgrading to IE7 but when I disabled IE8 there was NO IE anything left! I am so frustrated and nobody seems to have a clue what's wrong with this piece of junk! HELP!! Thanks I hope- K&K

No matter in which version, firefox always takes a long time to start up. Some time I even thought it failed to start. It appears in front of me often when I plan to re-double click the desktop icon again. Don't why.It must not be the problem of Gecko engine,because I also use Gecko based orca browser which has been updated to firefox 7.0 engine. It star up fast. Please fix this problem ASAP.It's painful when waiting..
