Main window maximizes width on the closing appplication.

[Gordon Lack]

If I close thunderbird using File->Quit (or ctrl+Q) the window maximizes to the screen width just before it closes and retains that max-width on the next restart.

This does not happen if I close thunderbird with the window-manager's Close button in the titlebar.

(I don't normally run windows full-screen, as to me that rather removes the usefulness of having a window system.)

Is this still an issue now that Thunderbird 60.4 is the currently supported version?

[Gordon Lack (gordon-lack)]

Yes, this still happens with 60.4.0.

[Paul White (paulw2u)]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:65.0) Gecko/20100101 Firefox/65.0

Steps to reproduce:

Thunderbird is being closed using File->Quit (or ctrl+Q), the window maximizes to the screen width just before it closes and retains that max-width on the next restart.

Actual results:

The main window retains maximum width on the next restart.

Expected results:

The main window should not have been maximised on restart.

The main window should not have been maximized on shut-down in the first place!

[Vseerror (vseerror)]

THanks Paul. It is preferred to place confirmed (NEW) bugs in some component, and not leave them in the Untriaged component.

Does this also happen to firefox?

[Gordon Lack (gordon-lack)]

FYI: As I shut-down Thunderbird teh .xsessions-erros file gets these entries.

[Paul White (paulw2u)]

Gordon, do you see this when closing Firefox or just Thunderbird?

[Gordon Lack (gordon-lack)]

I only see this with Thunderbird.

I don't see it with any other application.

[Paul White (paulw2u)]

No, only Thunderbird, and no other application.

The user I'm helping with this has just offered the following output from his .xsessions-errors file:

Does this help with the problem he is seeing?

[Richard Marti (richard-marti)]

The errors show a problem with the extension MenuOnTop. Could you test if this happens in safe mode (menu Help -> Restart with Add-ons Disabled)?

[Gordon Lack (gordon-lack)]

OK. I had a thought.

Started in Safe Mode - all is OK.
So I then went around disabling all extensions and *as I disabled one* the window maximized width-wise.
That extension is: CustomizeMyBird.

So I'll report the issue there instead.

[Gordon Lack (gordon-lack)]

Yes. CustomizeMyBird seems to be causing the problem. SafeMode is fine.

[Gordon Lack (gordon-lack)]

I can't find any way to close this report. Please do so...

[Paul White (paulw2u)]

Closing as "Invalid" - not an issue with Thunderbird itself.

[Paul White (paulw2u)]

Thanks everyone. Closing as invalid not an issue with Thunderbird itself.
