I experienced the same problem and the workaround was to select English from the Default Language dropdown menu (after performing a search).
I switched to another instance anyway.
Custom domain + SimpleLogin which generates a random alias (Tip: you can have emails forwarded to multiple "real" email addresses) + fake names and other personal info
Check out Anytype.io. It's, encrypted and versatile (use it as diary, task manager, etc)
I've been using it for a year after I used a long time Obsidian and then Logseq.
+1 for LibreWolf. I've been using it for ~2 years and it's better than Firefox from a privacy perspective.
Development is active, so updates are being pushed regularly.
As for vertical tabs, you can easily achieve it with Tree Style Tabs.
I strongly recommend it.
The first thing that comes to mind is a combination between SBOMs generated for your self-hosted services (trivy, syfy, etc) which are pushed to OWASP Dependency-Track and whenever some vulnebrabilies are detected (note: you'll get lot of notifications if the application is using a lot of libraries), trigger an event (not sure if node red can help here) which would run a script to disabled the vhost. (just a thought. I haven't seen an actual solution)
