Two more examples of infinite reload that have happened to me in the past 15 minutes (both in the same window with 83 Tabs, if that is relevant):
1) I was reading a blog, which linked to https://bash-org-archive.com/?3630 I right-clicked, selected "Open in New Tab", and the resulting tab immediately went into a really bizarre infinite-redirect loop, with the parameters changing randomly each time. Open opening a clean tab in a different window, pasting the URL directly, it opened fine and I found that the page had a "Prove you are human" CAPTCHA -- once I clicked that, the problem went away.
2) When I first went to report this (in the original window), I selected Help -> Orion Feedback. When I pressed the "Report a Bug" button, that went into an infinite loop (nothing visible except that the page-load indicator underneath the URL kept restarting), which was a bit startling. When I went back to the other window, opened a clean tab, said Help -> Orion Feedback, and pressed "Report a Bug", it worked fine.
Not sure what the commonality here is, but it feels like there probably is one. I've seen a few other instances of these infinite loops in the past few days (and had not previously), so I think it is somehow related to one of the recent updates.
