pixel Yes, I wasn't thinking very clearly last night. I used to get redirected to the html search automatically, and I don't seem to any more. NoScript is installed, which may give me a workaround for that.
That actually raises another question. On another machine, at one point I was offered a version of the Kagi plugin (Firefox) that seems to go directly to the /html/search instead of adding the redirection. Is there a way to configure that behavior? I can't find that anywhere now. Would be a nice addition to the plugin.
I did update the Kagi plugin yesterday on the machine I reported above, and the problem ensued, so correlation at least.
