I have had the best luck over at @kbinMeta.
/kbin meta
Magazine dedicated to discussions about the kbin itself. Provide feedback, ask questions, suggest improvements, and engage in conversations related to the platform organization, policies, features, and community dynamics. ---- * Roadmap 2023 * m/kbinDevlog * m/kbinDesign
Do we have something like “lost kbiners“? 😂 That’s the magazine we’re currently in friend. 😉
Maybe try asking on the Firefox magazine? They might have a better idea there. https://fedia.io/m/firefox
You'd probably have the best luck on the Codeberg repository or on Matrix. Though, I'm sure one of the primary contributors may see this as well.
You could also try @askkbin
Have you tried deleting the bookmark and recreating it? Is it possible the bookmark in FF is different than the bookmark in Brave?
Also, do you have any kbin scripts or extensions installed on FF that are not installed on Brave?
This did the trick. Thank you!
