(Firefox) My Issue "Firefox is already running.........."

Hello all...

I wonder if somebody could help me out with my issue, as minor as it may sound to some. First off the bat I would like to say that I have the latest flash and newest version of Firefox.

From what I am currently aware of I am having an issue with, Youtube. When I close Youtube and then attempt to open another browser of Firefox, to start fresh... it will stall for 3/4 seconds then a box will appear stating "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window" When I have been given the option to close it, everything goes back to normal. But why is this happening only to, Youtube?

I would like to add..If I have 2 Or more Firefox browsers open at the same time, the message does not appear, but when I individually close them all, the message will appear once more, when I open a new browser, after visiting Youtube. I would also like to add that Chrome, Opera and IE , is not experiencing this problem.

I have also tried Safe mode, but with the same results.

Any help/advice will be appreciated

I've seen the same issue and closing Firefox releases the RAM it has been using, gives the program a clean start when next opened. I find it a minor hassle when downloading and viewing videos. I also normally have 2 instances of Firefox open and sometimes two or more tabs with different sites open. Usually see the issue when Task Manager reports more than 500KB in use but also involved is Adobe Flash Player, might be 2 instances running with one quite a bit larger than the other. Ending process on FF usually also ends AFP.

This has only started to happen since I received a message early this morning around 1am to update Flash (It's a strange one because I have removed Flash, but still it persist)

Is this happening to your-self, Berton? If so how long has it been occurring for you? Or are you merely aware of it, from seeing it from somebody else? You have to excuse me I am trying to gather as much information as I can.

Are there any fixes for this?

Cheers.

Hello there, Callender, thank you for your time..Yes I have tried the Task Manager, even though it can be useful' I see it as sweeping dirt under the rug, and not actually tackling the problem.

The forth link that you have provided, I have seen this and I have also been a little weary about conducting this operation.

When I get back home in few hours time Or even tomorrow.. I will uninstall Firefox and save my bookmarks. Reboot, then re-install.

I will be updating as soon as Firefox has been re-installed .

Cheers guys.

Not having a problem, am watching a YouTube video as I type this. I'm on Firefox 34.0.5 but there is a newer version available.

I jumped the gun, when I said that I would simply reinstall..It will be a complete clean install, by going into the APPDATA folder, first, then deleting the Mozilla Folder. And as you instructed also deleting any left overs by going to C:\Program Files (x86)\Mozilla Firefox.

I have the uninstall_flash_player tool, when I need to remove flash.

Thanks boss.

Sorry, almost forgot about what you asked me to do earlier on. When I type "aboutlugins" I see this...
