This never used to occur. But when I use Task Manager to close Firefox, it closes the windows and tabs, but the "other" firefox.exe *32 doesn't, so I get a popup saying Firefox isn't working and should I close it.


Task manager has TWO processes for firefox.exe *32 every time I launch Firefox. My version is up to date.


Does everyone with W7 who uses Firefox have these same two processes in Task Manager? In other words, is this normal?

If it's normal, fine, but I don't think it is. Before I go to the Malware section of the forum, it seems best to determine whether or not this IS normal for Firefox. Because I doubt it.


So IS this normal?

If you are running the e10s functionality in Firefox, it's normal.

Firefox allows multiple homepages in separate tabs, maybe you inadvertently set the same page twice?

Use Sysinternals Process Explorer to kill Firefox instead of Task Manager.


Click on the Process title to sort - select the one where all appears indented.


Then go to Firefox and see if FFox #2 is running as a child process of FFox #1.


If it is, right-click on FFox #1, select "kill process tree" - this will kill both.


Extract the procexp.exe file from the zip file; save to Desktop or Documents.


Right-click on procexp.exe, select "Run as Administrator"


Sort the column as described above.




Regards. . .
