Recently I have noticed that after installing adobe flash player plugin I get ads that comes frequently when viewing youtube. I little ad that says "ads not by this site" and a little timer... I also other flash ads.

It has been reported that adobe flash player does cause this problem. Removing it removes the problem but I then cannot play youtube videos. Is anyone else having this problem? I have adblock plus but it has not done anything.

try to remove or disable the Easy YouTube Video Downloader 7.0 & Freecorder 7.0.0.13 extensions - they might contain adware.

also run a full scan of your system with the security software that you have in place and different other tools like the free version of malwarebytes & adwcleaner to make sure nothing else shady is going on.

Also remove Browser Manager (currently disabled)

Extensions that do not have a "Remove" button are installed by other software and are not under control of the Firefox extension manager.
Such globally installed extensions are usually found via a registry scan or are installed in a location that Firefox scans for installed extensions.

Extensions installed this way need to be removed via the settings (options/preferences) of the program that has added this extension or you need to uninstall this program via the Control Panel.
In Firefox you an only disable such an extension.
