Would you be able to do a screenshot to show what you're seeing? Thunderbird has retained the menu bar for reply, forward, etc.... so I'm unsure what you see. Thank you.

Thanks. I've attached two screen shots:

_01: The way my Thunderbird inbox appears. _02: The way the text of your message appears when I right-click on its header, then click on "View in new Tab", and then click on that tab.

FYI, previously when I received Emails about responses to Mozilla support requests like this, I seem to recall that the message would contain something I could click on to get back to the web page contain the thread of replies. This time, if there was such an icon in your message, I couldn't find it. I had to search the Firefox history to find the page where I posted my question so that I could reply.

I am running Windows 11 Pro with the latest version of Firefox. This change has made reading and responding to my Emails very slow and difficult. I appreciate any help you can offer.

It looks like the message pane isn't active. Try pressing F8 to activate it. I presume you use the classic layout. Let me know after trying that.

Yes, F8 seems to have solved it.

Lately, I seem to find a lot of unwelcome surprises with release updates from all vendors. (E.g. From time to time, Windows resets my default sound settings. A favorite trick is to assign the default speaker to a device incapable of generating sound, such as a microphone headphone jack with nothing plugged in.)

From time to time, Tbird inexplicably turns off the QuickFilter Toolbar, but I know how to turn it back on.

Thanks VERY much for your helpful suggestion.

Can you direct me to some documentation I could read where I could possibly have found this out for myself and not have to bother nice people like you for assistance?

THANKS AGAIN!!!!

But... but... we LIKE having you write to people like me. But to be helpful, almost everything I need is at the View menu: toolbars, layout, and folders. Those give the primary setups. If you want a full layout, I did a layout that may overwhelm, but may also be helpful.

I think when I have the chance to study it, that image will be very helpful. The Catch-22 is that when all of the sudden the screen layout looks very unfamiliar (as happened to me this morning), it's hard to figure out what parameter will fix it. For example, I assume that the F8 you recommended is a short-cut for some combination of View parameters. I'm not sure exactly WHY it solved my problem and got my screen looking "normal" again, but it certainly did.

Sometimes even the smallest change can be an annoying time wasters. A while ago, Thunderbird changed the text on the thingie you click on when you want to write a new message. It used to say (I think) just "Write"; now it says "New Message". I guess SOMEBODY thought this was clearer, but for a few weeks every time I saw it my brain would hesitate and wonder if it was announcing a new INPUT message just received. If a change had to be made, imho "Write message" would have been less ambiguous than "New Message" -- but that's probably just a quirk of a crotchety old lady who still misses user manuals. [g]

I really appreciate how much time (and gnashing of teeth) your on-target advice has saved me [g].

You are very welcome. That F8 message pane entry is on View>Layout pane. Whenever lost, the View menu items will usually see you through. And if you ever miss the menu bar, just press the Alt key. Regards to you.
