Mozilla-Firefox 115.5 was included in the update I carried out on the 19th. And I have just seen some really odd behaviour from it. Clicks on links stopped working and I could not close a tab by clicking on it, although I could still use a click to move to another tab. When I did so, the window was blank; in other words FF had lost the ability to repaint its window.
I closed FF and reopened and everything seems to be normal again. I've never seen anything like that before.
Sometimes you will get more or less odd behavior from Firefox when still running the old versions binary after the firefox package has been replaced by the update. Usually Firefox eventually says that it needs to be restarted, but before that you might see some more or less strange behavior.

No, this is a fresh boot. The update was a few days ago. It's probably something quite trivial. Everything appears to be normal now.
Firefox-esr has behaved strangely for me for some time. Every once in a while it goes to 100% CPU (on one core) and during that time it won't redraw the windows in some tabs, some tabs have windows that are half-drawn, links don't work, and sometimes scrolling with the trackpad or with the arrow keys (one or the other but not both) doesn't work for a while. Restarting Firefox makes it behave again, or I can just wait and it eventually settles down. I haven't figured out whether it's my configuration (apparmor and many extensions) or whether it's Firefox itself. I'm running the Firefox-esr provided by Slackware64-15.0 and its updates.

That looks like the same thing I saw. I don't use apparmor but I do have some extensions
hazel, would you, by any chance, happen to have i915 graphics, as I do on my MacBook Pro 2012? I read Mozilla's advice for Firefox slowdowns and, following that advice, I'm currently running with Firefox's hardware acceleration off. Firefox feels a bit less laggy and I haven't had any glitches in the last hour. If I still get random glitches, I'll report back.

Yes, I do. Thank you, I'll try that.
OK, done. I'll see what difference it makes to performance. Probably very little as I seldom stream video. But as the glitch was a one-off, I probably won't be able to find out if the new setting makes a difference.
Recent months/years FireFox (FF) ESR has often been pretty slow at times... I read an article (maybe at TechRights.org) that Mozilla is deliberately making FF ESR worse because they dislike people using old versions.
I've also noticed something odd on one particular site and it might be more general. There's a link to log in as a subscriber, but now when I hover over it, it doesn't behave like a link and seems to be dead. It does however work when I click on it. This is consistent behaviour. A minor irritation but irritating all the same.
Since this is also about how something looks, it might be related.
Have you attempted to rule out the issue being with the site (bad coding / css etc)?
Could be, although I've never noticed anything odd about this site before and I've been visiting it for years. What happens now when I hover is that the cursor doesn't change shape as it ought to do for an active link and no address appears at the bottom of the page. It's as if the link were dead. But it's just a visual thing; clicking on the link still works normally. And it's not just in Slackware either. I'm currently using a later version of FF in AntiX and seeing the same thing. If I hover over a button, the cursor changes, but for a link it doesn't. However in gmail and on most other sites, the links behave normally. So at some point in the FF update cycle, there was some permanent change in the way the cursor shape responds to certain links.

Well I tested the link in Firefox and Chromium and the results were the same (for me anyway)
I got a URL at the bottom of the screen and the mouse cursor changed when moved over the link. (screenshot attached)
The only thing that didn't happen was changing from yellow to orange like the "Unlock Access" button. But that's likely a CSS issue.
