Running Firefox 126.0, which Firefox' About link says is current. Dell laptop running (current) Win10 Pro. As recently as last Wednesday (15 May 24), everything was normal. Since yesterday (16 May), on the Wall Street Journal site, after I have logged in, I no longer have access to articles' comment threads. The Show Conversation button shows 0 comments (which is erroneous), and when I click the button, it changes to Hide Conversation (which is normal), but nothing else happens--just white space and no comments or comment text entry field. On Fox News, the comment thread doesn't display, and there's not even displayed a link to a comment thread. Until yesterday, the thread normally displayed, but required login to comment. Since yesterday, logging in changes nothing: the comment thread still doesn't display at all. On X (nee Twitter), when I click the login icon, I get the usual login box--but it's solid black with only a rotating arrow signifying "loading." It never finishes loading. An added fillip: X, as recently as last Wednesday, displayed in its usual black text on a white background. Now it displays as white text on a black background. I can click on X links sent to me and get that particular X post to display, but I cannot log in. When I go to those sites in Edge, everything behaves normally: I have access to comment threads, and I can log in to X. One exception: X displays as white text on a black background on Edge, also. This doesn't seem to be an X thing, though; on my wife's laptop (Firefox 126.0), running WIn11Pro, her X display is the "normal" black text on white background. I haven't changed any settings in Firefox. I do have a couple of ad blockers, and I've turned those off, one at a time and both together; that had no effect. How can I get things back to normal in Firefox? Thanks Eric Hines
