Firefox claims she is already underway and will let me start a new session after closing of

I had this problem intermittently on my Dell XPS 8000 and my laptop HP nx7400. Dell runs the latest version of Windows 7 Pro and HP running XP Pro (fully updated). After closing a session of Firefox and other applications running, Firefox won't let me open another session, saying that "Firefox is already running... Please close the session... "This is not an exact quote, but you get the idea. CTRL-ALT-DEL and all other conventional means do not work and I have to reboot the system. It is a royal pain... and I need a pain relief! Any suggestions? I can go back to an earlier version of Firefox until I see a solution... is not bad, but I really like 4.0, and I do not look back in the 'progress '.

Thank you.

Tom

Looks like it is suspended when you quit, and then later try to restart Firefox.

      Crash ID: bp-9dc68df0-f096-454c-82c3-e32bf2130531

      Whenever I try to open Firefox, it goes immediately to the crash reporter who said 'we're sorry. Firefox has been a problem and crashed. We will try to restore your tabs and windows when it starts. »

      I ran Malwarebytes, Super Antispyware, Kapersky Security Scan, Spybot and Microsoft Safety Scanner and none of them does not seem to work.

Then I did a complete uninstall of each program using the uninstall program supplied with Advanced SystemCare. I restarted my computer and now it works! Thanks for the help!

      P.S. I was able to find an immediate temporary fix yesterday by browsing through another forum where one of the mods had a fix. He said that the issue had something to do with DEP.

      Here is his discussion with another Member:

      ===========================================================

      In General, when an accident of app, or crashes, a record is made in the event viewer. (type eventvwr in the search) go into windows journal > application tab.

      You are looking for critical errors (they have red in the left hand column)
      

      Look for the application, the app blocking crash or anything related to the problem

      When you find them write down the Event ID and source code and tell us what they are. I have a sneaking suspicion it will be event ID 1000 source 100.
      
      

      Let us know if you need help

      Hey guys, I'm so glad I saw this thread I have problems very similar to POS.


      Basically, I just recently implemented a new system and installed Windows 7 above. This is where my first errors have occurred, getting an error of installation on the first try to install Win7. I had a look around the web trying to solve this and got through the installation of the second time around.

      However, after having the computer for a week now he acted strange throughout various errors and a blue screen appears from time to time.

      I get blue screens, IExplorer, COM Surrogate and Explorer Windows Defender-a stopped working, even my sfc/scannow was interrupted due to the error... This is my first experience with this type of problem and I haven't really found someone with a clue on this subject yet.

      Until I read your reply, zigzag3143. I had a look at my eventviewer out of curiousity and it just so happens that it is full of Error Event ID 1000, Source code 100, with Source stated as Application and my Avira Antivir Personal antivirus software. It should be noted that prior to Avira I had Avast antivirus installed, so I don't suspect the usual antivirus issue.
      

      Yes, zigzag3143, what exactly is this event 1000 code Source 100 all about? It would be so nice for a change, to get this resolved from the first post on the web, you know? Haha, anyway, I cross my fingers that you can crush it for me.

      Thanks.
      
      
      
      

      I beg of you. I thought it was that but wouldn't you jinx. OK Event ID 1000, 100 source is often caused by a built-in virus protection app called adj. Dep, or DEP data, prevent applications (read virus) to launch in 'protected memory space. It is almost not necessary but that's another story.

      He find. It is located in your system control panel > advanced system settings > Advanced Options > performance settings > DEP

      -Default is MS apps only (I think) what ever he is set to change. If that does not cure the problem, you can even turn it off. There is a turorial here on this. http://www.Vistax64.com/tutorials/12...ble.html?LTR=D

      Let us know if she continues

      ===========================================================

      LONG STORY SHORT... I just did what he said and follow this link to
      Learn how to turn off my DEP for a quick trouble so if someone reads this and is a problem, it can work for them, as well.

      Your information help me with a permanent fix because I have activated DEP before I restarted and now everything is back to normal

      Thanks again!

      Some formats like jpg does not support layers, that's why it opens as a locked background layer.

      In the past 48 hours, all of a sudden, the new tab featured on my PC, using Firefox 3.56, simply stopped working. I do not change the settings, or download a new version of Firefox. It has just stopped working. There are other scenarios where it still works (for example, if I want to open a link in a web page, I can right click and open link in a new tab), but if I want simply to have several websites open at one time on my PC, I have to have multiple versions of Firefox open as my new tab option seems to be disabled or something.
