Same problem here with Firefox 118.0.1, Ghostery 8.11.1, running on OpenSuse Leap

[tdivis]

Same here on both Linux and Windows. Same errors in console like MrWaggel. Pausing Ghostery fixes it.

www.youtube.com/:1 The resource https://i.ytimg.com/generate_204 was preloaded using link preload but not used within a few seconds from the window's load event. Please make sure it has an appropriate `as` value and it is preloaded intentionally.

[chrmod]

Thank you all for the reports.
The problem comes from new kinds of rules that are used to provide ad-blocking on youtube. Ghostery adblocker engine does not handle arguments to some rules properly and in an edge case it can break websites. Sadly this happened on youtube.
We found the problematic rules and removed them until we support them correctly.
A proper fix should come very soon - please stay tuned.

thnx boss for resolving the issue
