Sleazy Fork

the script hasn't worked for me for months now. I don't see the bar on the left and the viewed videos are not hidden.
I updated the plugin, removed and installed several times but got no results. what can I do?

Sorry for the inconvenience but the script is working completely fine for me at least.

There is only one remedial action, that is clear your caches.

You can also share a screenshot of the console in the developer tools.

I just clean my browser cache but nothing.
Here my screenshot

I think you or some extension is blocking essential JS features of the browser. As you can see in the screenshot, a large amount of errors are related ERR_BLOCKED_BY_CLIENT which indicates such behaviour.

While the last error indicates that your script handler extension (tampermonkey, greasemonkey etc) is failing to inject the userscript into the page.
