Hello   mail.vchpro,

Pixel Perfect hasn't been compatible with Firefox for years, and has therefor been removed.

Would you take a look at this (new) extension and see if maybe that will work for you (?):

But Pixel Perfect worked, but you delete it. Please, can I setup it? I understand, that it can no work. New extension installed, but when I click at him, it doesn't work. You send url to Issue, where people speak about firefox DEVELOPER EDITION, but not Firefox Standard. In Firefox Standard it worked.

The developer of Pixel Perfect hadn't migrated the add-on to webextension; that's why it was removed.

Mozilla is not responsible for add-ons; merely hosts them as a service to users.

It's the developers who are responsible for updating their add-on; and if they don't; there is nothing Mozilla can do about it.

Sorry .....

But can you give me last version, that you deleted? I want to try it to use, so I understand that it can not work. Pixel Perfect worked in the latest version Firefox, beforr you deleted it. Did you test it, when you delete it?
