Script not working from few months

[B00Bmaster]

Hello
1st of all thanks for the script, it helped me a lot
but from past couple of months it stopped working for me
does not show those two options in the tamper-monkey to configure and to check links on the page
i tried grease-monkey too there also those options are not shown
or even in right click those options are not shown
please help me

Script and Firefox both are updated
any other info required I'll be glad to provide
