have you gone through Disable or remove Add-ons

I tried everything

As I said before:

there is no remove button I removed it manually I resetted firefox still it shows up in add ons

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.

• https://developer.mozilla.org/en/Adding_Extensions_using_the_Windows_Registry

Extensions installed that way need to be removed via the settings (preferences) in the program that added the extension to Firefox.

I don't use Windows, I have a mac, does that make any difference?

Furthermore I don't know which program installed the extension

There are other locations Mac

• /Library/Application Support/<vendor>/Extensions/<appid> or ~/Library/Application Support/<vendor>/Extensions/<appid>
• /Library/Application Support/Mozilla/Extensions/{ec8030f7-c20a-464f-9b0e-13a3a9e97384}

• https://developer.mozilla.org/en/Installing_extensions

Thank you so much!!
