Sleazy Fork

Why are your scripts installed twice instead of automatically updating?

Hmm... i don't know...
What extension you use:
Tampermonkey or Greasemonkey?
And what Browser ?

Maybe the last update correct that?
I fix the @include and @match which not working (applies for all sites...):

But i see in your screenshot, your pb is with "IAFD WideScren Dark And Gray" script
and not with 'Indexxx- Show directly thumbnails of Actress'

Have you too with it ?

Anyway for IAFD, you can use my userstyle (just do the same - Only CSS customisation):
IAFD - Widescreen Dark And Gray v.19

IAFD:
Just tested and install only one...

Maybe was a problem of version:
just delete v.18

What extension you use:
Tampermonkey or Greasemonkey?
And what Browser ?

tampermokey v4.16.1
Stylus 1.5.25
chroumium 95.0.4638.69

I install your IAFD CSS from here
https://sleazyfork.org/zh-CN/scripts/412637-iafd-widescreen-dark-and-gray-v-19-65

It seems that after the script name changes, it will be considered as two scripts by the Fork.

Possible....

Install as userstyle work well too.
But you need install Stylus extension before.

I have another problem with this IAFD userscript:
It applies to all sites (when you install it as userscript and not as userstyle).

I don't understand why...
Maybe a format problem?

I posted a request in the forum about it:
Help: Prolem with include in my userscript (userstyle) - It applies to all sites, not only IAFD
