When you try to start Firefox I get a message saying "a copy of Firefox is already open. Only one copy of Firefox can be open at a time. "I started a new profile, but the Profile Manager always tells me that by default it is still in use.

When you try to start Firefox, even once, I got a message saying "close Firefox. A copy of Firefox is already open. Only one copy of Firefox can be open at a time. "This issue is addressed in Mozillazine but nothing I've tried there seems to work. I started a new profile in the profile manager that gets at least upwards and the functioning, but strangely enough the Manager also told me the old (default) profile is still underway, although I can't find a way to close it. Also, I can't find the default profile in my Profile Manager. can anyone help?

This has happened

Just once or twice

== I thought that I had left Firefox and he was new.

I get the same problem from time to time. It is not a solution but I go into Task Manager (select by right clicking on an empty area of the start bar) and under the research process and, invariably, there is a 'hidden' version to use the FF. I selects & close via Task Manager and then am able to restart FF.

    If the hash is correct and then try running SFC/scannow from a command prompt - it may work, depending on how the software manufacturer set up the drive, but it is preferable to use in conjunction with a good OS disc, rather than the recovery disk.

    Hi I can not launch Dreamweaver cc 2015 all I get is a message saying lack of mfc120.dll

    I am running Windows Pro 8.1

    Thank you

    Yes I did and it did not help, I already rebooted my machine

    However, after a search, I discovered that mfc120.dll is part of the library of redistributing Microsoft visual studio:

    So I then did a search for MS Visual C++ Redistributable package
