I can reproduce in Troubleshoot Mode:

1. Help / Troubleshoot Mode (only Add-On is Phoenity Icons)
   2)Mail Start Page autoloads fine -- Works as expected
2. Go / Mail Start Page again -- blank screen

Workaround is restart T-bird.

What happens if you remove Phoenity Icons?
What errors do you see in Error Console (ctrl+shift+J) just after you try to open the start page?

OK.... here's what I did:
Delete Phoenity Icons. I now have no add-ons
Restart T-bird. Opens as expected.

Error Console shows attached.

I clear Error Console completely (Trash Can in upper left)

Go / Mail / Start --- blank page (defect)

Relook at Error Console .... still blank (nothing new).

I tried using the Default Mail Start page.... and everything works as expected.

As you can see from a comment I made in the original post, I have a very unique Mail Start page.
... and somehow...... that's the cause.

If you can offer any advice (other than don't use that location) on how to fix my issue, you would probably be right to close out this bug as extremely unique to me and doesn't impact anyone else.

I like my odd setup... and can live with restarts occasionally.
I appreciate all you do to make Thunderbird great....

.. when I say using Default Mail Start page.... I went to Tools/ Settings / Start Page... and chose Restore Default

Comment 9

[Wayne Mery (:wsmwk)]

So you are not using the default start page?

Comment 10

[RickSparky]

No..... I'm using:

C:\Users\SPARKY\AppData\Roaming\Webshots\The Webshots Desktop\Webshots Wallpaper.bmp

Which works fine when first loading.

No..... I'm using:

C:\Users\SPARKY\AppData\Roaming\Webshots\The Webshots Desktop\Webshots Wallpaper.bmp

Which works fine when first loading.

Just out of curiosity, how big is this Webshots Wallpaper.bmp in MB? I only ask because BMPs tend to be very large as compared to JPG or PNG and I'm wondering if there's a knock-on effect at play.

Not that big ... see image.

Reporter, do you still see this issue when using the latest version?
What information can you add to clarify the steps to reproduce this issue?

Comment 14

[RickSparky]

Thanks for looking at this !

Yes, this still happens.
I'm using Release 102.9.1, which I believe is the latest.

How to reproduce:

1. Open Tbird
2. Go / Mail Start Page.... works as expected.
3. Either right away... or later after reading some mail.... Go / Mail Start:
4. Unexpected result: Blank mail start area... with message at the bottom: "Loading Message ..."

Thanks for looking at it. I know I have a unique Mail Start page... but it (generally) works for me.
I've learned both not to take this action.... and, the workaround if I forget... of closing Tbird and reopening.

Comment 15

[RickSparky]

.... and... once that has happened... the message "Loading Message ..." remains, the Message Pane is blank..... and if I choose to try to read any email there is still nothing in the Message Pane... it freezes in that state.

I can confirm the bug. Possibly it is Windows-Only(?)

The bug does not depend on the image type.
It also occurs with a different URI scheme. (e.g.: "file:///C|/temp/pic.jpg")

A restart of TB is not necessary. It is enough to set the pref live.

STR:

1. reset the start page
2. restart TB
3. show any message
4. set the start page to "file:///C|/temp/pic.jpg" (or any other picture)
5. go back to the message window
6. type [ALT]+[HOME] (windows)
   -> TB shows the Picture
7. type [ALT]+[HOME]
   -> TB shows a white Page and stalls

No message in the error log,
If you select another image between step 6 and 7, TB will display the new image without any problems.

I myself have been using an HTML file as a start page for years without any problems.

As a workaround, it is actually sufficient to use a simple HTML file that only contains a reference to the image.

Create a text file in that folder.
Name it "startpage.html"
Past as content:

<html><head></head><body>
   <img src="Webshots Wallpaper.bmp" alt="Start Page" />
</body></html>

Set that file as start page

TB91.13.1 works fine.
TB102.11.0 to TB115.0a1 are broken.

Comment 19

[Wayne Mery (:wsmwk)]

Does this only fail with bmp or only on Windows?
Because daily build on Mac with png works for me.

No. See STR in Comment 16
PNG format also fails here.

or only on Windows?

This may very well be the case.
