For those using uBlock Origin, you can control cosmetic filtering with the "Parse and enforce cosmetic filters" and "Ignore generic cosmetic filters" options on the "Filter lists" tab of the extension settings. The uBlock Origin toolbar button also lets you enable or disable cosmetic filtering on a per-domain basis. Disabling this may improve performance on slower/older devices, but I don't notice the speed difference with uBlock Origin's implementation on most recent devices.
