Hay Friends i am waiting your answer.
Hi komalsinghx3, welcome to the forums,
I guess not everyone knows how to use Google, so I’ve found it for you
you can remove that by using the registry editor.
just use the code in the registry editor HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Firefox\extensions
thn after that you will see something like this 20a82645-c095-46ed-80e3-08825760534b
and right click on that and delete.
