• Cannot start Firefox except in Mode safe

  Everytime I go to start Firefox, it crashes with no error message. I tried to re - install, revenant and reset firefox and come back at least 28 FF I was able to start safe mode, but it means that I have a) do not have my Add-ons and b) I have to restart twice to get to anything.

  I tried to create a new profile, but the profile editor crashed when I clicked on the "Create a profile" button, so I'm sure that's not anything in my profile data which crashes firefox.

  I can't submit accident report links because it isn't everything, creating so please do not ask for those.

  It turns out that I had to restart my computer, but it's a stupid reason for a browser to break.

• Cannot start Firefox using quick launch, etc. Window of Firefox (or anything else is not started. Now using IE (Ugg)

  I'm unable to launch Firefox launch button using / fast, Start Menu, or anything else, don't get no error message or of the Firefox window. Tried to uninstall and install then always without success. Cannot use the fix suggested to use a new profile because I don't get a Firefox window. Have a HP with Vista, RAM 2Gigibites, computer Pentium processor.

  Like you, I found I couldn't yet launch FF28 and therefore could not try to create a new profile or add ons disabled.

  Taking the advice of another poster and completely uninstalled FF28.

  Then went to the site of the beta:

  http://www.Mozilla.org/en-us/Firefox/beta/

  Installed FF29 (currently 29.6) and had no other problems.

  She's still all extensions / add ons I have tried to run with FF28 but opens and runs without hassle.

  Can only assume FF28 had some problems for some operating systems that are not there in FF29.

• Why Windows cannot start the Firefox Service on Local computer?

  Hello, Tech Savvy people-
   
  For some strange reason, the message in the title is what I get when I look under Services in administrative tools.
  I am told:
  Windows could not start the Service of Firefox in the Local computer
  Error3: the system does not have the selected path.

  I did a full scan of my files (sfc/scannow) and my drive (chkdsk); completed a full virus
  In addition, malware scan and all the so-called runs along fine.

  But Firefox 12 needs several clickings of surface, and when it finally arrived, several minutes.
  Boring.

  No idea why my local network or Local computer cannot start Firefox?
  Can anyone suggest how I could get my system to find this path?

  Firefox used to mount quickly enough, and my other browser, IE9 still does, even though I don't like
  using IE and for about 3 years found Firefox generally to be a superior browser.
  Feel a little miserable if I go back to IE.

  Thank you for answering this aggravation.

• I'm unable to start Firefox. To get the message that it is already running. Cannot find my profile using '% APPDATA%\Mozilla\Firefox\Profiles| '. What should I do

  I'm unable to start Firefox. To get the message that it is already running. Cannot find my profile using '% APPDATA%\Mozilla\Firefox\Profiles| '. Restarting my computer did not help. Because I had this problem I also noticed that all my favorites that I had copied in Windows Internet Explorer also disappeared. I use Firefox as my main search engine and usually do not use Internet Explorer. I am running Windows 7 on my machine.

• Cannot reset Firefox.

  When I start Firefox, it happens with Yahoo, NOT with the default Firefox. If I try to reset Firefox, I get the response "well, it's embarrassing" and cannot reset. I went to the deleted control panel Firefox and downloaded and re-installed FIrefox from the site of the Mozilla Foundation, and the problem still persists. I can't get rid of Yahoo.

  As a side note, Chrome works OK. When I start Chrome, I automatically open four tabs. From time to time, opens Chrome a fourth tab... and it's Yahoo. I can go into the settings and delete the fourth tab and everything is OK for a while, but eventually the fifth tab opens again, and I again to remove. Don't know if these are related issues, but I don't believe in coincidence.

  I use WebRoot security and have scanned my PC and deleted all the threats. As WebRoot is, my PC is clean.

  You can check the suspicious extensions or recently installed unknowns.

  Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem.

  Hi, I do not know where to turn: the person who takes care of all the stuff of count is out of town, this friend started Firefox and there was a message about an update, I thoght I again just click on install and wait to re start Firefox. But what I remember is this another open window and asked me to choose 'something' (an icon or banner or?), I thought I have to click on an element (I guess I should read all clearly). Firefox updated to 3.6.4, but it also inserted some sort of what might be called a banner? But it does cover only partially the half right of my 3 toolbars at the top of the Firefox window. It cannot be used to something else because it's just a mess of colors and unknowns, except for what looks like a 'top' and what I recognize as an icon of Firefox (but only partially visible)! Now, what he does, it's partly hide this part all the toolbars and they are difficult to read and to do to turn this 'thing' impossible to understand, if I keep to? I can't find in any case to remove it or use it? But since the icon of Firefox is about it, I think you need to know what it is and how trash. I'm sorry for this accident caused my my inattention, but I'm not much of a computer person - HELP! Thanks for any help. Judi

  This has happened

  Each time Firefox opened

  Today is Thrsday June 24, 2010

  The only thing I can imagine: it's a character.

  Tools-> Add-ons-> Themes
  Here should be the character (light theme)
  and a button 'delete '.

  Click on it (delete button), and he (Persona, this mixture of colors) should disappear instantly.

  This help you?

• "Check my spelling as I type" box became unchecked everytime I start Firefox.

  When I start Firefox, the "Check my spelling as I type" is unchecked. When I check it, it remains active and the spell checker works correctly, as long as Firefox session remains open. When I close Firefox and re - start, the box is unchecked again.

  Thank you.

  Your list of details of the system shows that you have a user.js file in the profile folder to initialize prefs each time you start Firefox.
  The user.js file will be present if you or a other software created this file and normally will not present.

  You can check its contents with a text editor (right click: 'Open with'; do not double-click).
  The user.js file is read whenever Firefox is started and initializes the preferences to the specified value in this file, so the preferences set via user.js can be changed temporarily for the current session.

  You can remove the user.js file if you do not create this file yourself.

  You can use this button to go to the Firefox profile folder currently in use:
