CORRUPT FIREFOX PROFILE MANAGER PORTABLE
So for the last couple of hours, after forcibly closing it via Task manager, it has not been possible to successfully launch the portable edition. Please close other instances of Firefox before launching Mozilla Firefox, Portable Edition."Īs said, this error message pops up after trying to launch my preferred version of Firefox, ie the Portable Edition, even after restarting the PC, with no Firefox launched, as soon as I try to launch the Portable version at the above location D:\Portableapps\FirefoxPortable\ or on another partition, although before today's mentioned incident above, this has never happened before in that form, as even in Task Manager, there's clearly no form of firefox running.

"Another instance of Firefox is already running. The question is what triggers this to affect not only this, but another portable version in another location + the installable version from Mozilla, when I have never had a similar issue in over 15 years of use?Īt the top of the popup-window, we have Mozilla Firefox, Portable Edition | I did find out from forums, one could delete parent.loc in C:\Users\user\AppData\Roaming\Mozilla\Firefox\Profiles\fault-release and that seems to help the installable Firefox start normally with the file apparently recreated BUT trying to delete the similar file I saw in the portable version at D:\Portableapps\FirefoxPortable\Data\profile makes no difference. How could that have affected the Firefox installed from this site but never used except today, because i certainly did not close it in any unusual way? Was the problem closing the instance under "Background processes" before that under "Apps" in task manager which caused some corruption (of what/where?), although as I have said, I have over these many years never had any issue with closing any program whatever the order in task manager. So now I have 2 problems, with a fresh version of Firefox installed from this site but never used, except today + Firefox Portable, both currently unusable. What coould be triggering a problem I have never heard, except years ago, when I had a similar problem, but at least then, one could see an instance in the Task manager, that was for some reason not closing when one closed Firefox? At that time, I think there was a fault solved subsequently by an update. I am using this Firefox version for the first time today, since I normally use the portable version, but out of the blue, it is also suddenly not starting.

Originally, after noticing the above problem, I tried it out & it worked BUT right now, it is also showing the same error when I try to start, although as said there is no indication in the task manager that any instance of firefox is running. not the portable version mentioned above, which I rarely use. I have a a separate version of Firefox installed from, ie. This is very frustrating, since it has my bookmarks & other settings but cannot use it and no other instance or Portable firefox installed elsewhere is usable!!. I re-started the notebook and to my surprise, I now get the error message whenever I try to start Firefox portable like I have done thousands of times before, although no one has started any instance before. I also tried another instance of Firefox portable I have at another location, same problem. When I tried to start Firefox shortly after that, I got the error message another instance was running & I should first close it, although there was clearly none visible in the Task manager, that I should first close! I have never ever had a problem with closing Firefox or any process before via the task manager. I was in a hurry and started with closing the Firefox instance I saw under Background processes, before going to quickly close the instances under Apps. Usually you see "Mozilla Firefox, Portable edition." under "Apps" & "Background processes" in the Taskmanager.
CORRUPT FIREFOX PROFILE MANAGER WINDOWS 10
I have the latest available version as of today, Windows 10 Home 64 bit, 8GB RAM notebook, all Windows updates installed.īecause I had many tabs + 2, 3 windows open when I started the notebook from hibernation, it was taking a bit long for it to completely "wake up", so I decided to close Firefox, which I assume was taking most memory via Taskmanager, something I have done countless times before, on this notebook. I have a very annoying problem with Firefox Portable.
