Thunderbird starts in a full-screen mode and cannot be restored

A couple of things to try:

Alt+F8 is the keyboard shortcut for resize.
Try opening it without the old profile. could be something in that needs to removed. You can do this with:

thunderbird -ProfileManager

Thanks

I'm sure I clicked all the F-buttons from left to right (and I even
remember that I clicked Alt+F4 by mistake :P) and it didn't work :/
After this post, although, I switched to Win there I restored app and
switched back to Linux. It worked but not completely. Next few days
past it came back in full screen and I don't know how. The same
procedure as above and it works till now. I will tray to produce such
situation one more time (I think it has some connection with maximizing
app window in Win) and post a bug on Thunderbird forum because it isn't
an Ubuntu bug.

I tried. The state of window is somehow stored in profiles files and
that's why in other profiles window looks right and in that specific one
it is a full screen.

Thanks for a response :-)

Same situation here...

Can you please attach screenshots of this issue i have a feeling i know what you mean but i would like to be sure

Same issue here:

Dualmonitor after latest gtk update or something like this fullscreen...
very annoying...
worked before...
guess that it has something to do with gtk....

Same issue here...
Created a new profile... worked like normal....
Then, opened previous profile... tainted thunderbird again.

My solution [hack] was to create new profile and delete the old one:
Creating a new profile means you need to set up your mail accounts again. *Please back up all of your email messages before doing this! I'm not responsible for any mail lost during this procedure.

1) `thunderbird -ProfileManager`
2) Create new Profile
4) Start Thunderbird using new profile
5) You will then have to type in your setting again.

Note: If you get thunderbird working normally, you will taint thunderbird if you open your previous profile and will have to start again. Because of this, I ended up deleting my previous profile.

Hope this hack helps.

I found a very simple and safe workaround.

1) Open Tbird.
2) Change Windowmanger (e.g. compiz to metacity). You can do this easily utilizin Compiz Fusion Icon.
3) Now should be able to resize the window.
4) Change back to your original Windowmanager.

This worked fine for me, hope it will work for others, too.

I had the same problem. I went into Advanced Desktop Settings > Window Management > Extra WM Actions and turned the "Toggle Fullscreen" option on, assinging it to Alt-F11. I then simply pushed Alt-F11 while Thunderbird was highlighted and everything was fine.

I have a possible solution to this problem. The following worked for me :
* Go into your ${HOME}/.mozilla-thunderbird/<profile> directory
* Move localstore.rdf to localstore.rdf.original

It appears that some of the screen sizing information is kept in this file. Moving the file worked for me, but it may be possible to excise the offending XML directly. I didn't try this, however.

this sounds like it was caused by a upgrade example gutsy to hardy
upgrade since you run tbird after moving the .rdf and once renamed
starting tbird again will generate that file again, Ive seen this type
of issue alot and thats why im thinking its a corrupt profile due to
upgrade ubuntu versions.

For everyone that saw this bug can you please confirm the process that
Matt did fixes this. Matt can you please post or attach here the old
profile so i can determine what happened.

Yes, moving localstore.rdf out of the way worked.

This is example of localstore that triggers this behavior. I tried to keep it small.

Exactly, the problem lies in the ~/.mozilla-thunderbird/xyz1234.default/localstore.rdf settings file.

I can reproduce the problem quickly on Ubuntu Hardy with Dual Monitor.
My right monitor has a higher resolution than the left one.
I start Thunderbird, maximize it on the right monitor (that with the higher resolution), close Thunderbird.
When I open Thunderbird again, it opens in fullscreen on the left monitor and gets stucked in this setup. Nothing helps to change that outfit.

You can restore the windows border with these steps:
# Close Thunderbird
# Edit the file ~/.mozilla-thunderbird/xyz1234.default/localstore.rdf
# Search the entry
  <RDF:Description RDF:about="chrome://messenger/content/messenger.xul#messengerWindow"
                   width="800"
                   height="600"
                   sizemode="normal"
                   screenX="5"
                   screenY="5" />
# Change the width, height and screenXY entries to the ones you see here
# Restart Thunderbird and it should have its borders again.

I can confirm this problem for lucid with thunderbird 3.1.3

I can confirm this is still a problem in the most recent Ubuntu version.
Happened to me after dist-upgrade to Ubuntu 10.10

Changing the sizemode and height/width in localstore.rdf worked for me, thanx for the tip :)

Removing the localstore.rdf file solves the problem, but in my case it's not related to an upgrade. When I apply the fix, the problem reappears after a while. Right now it happens about 2-3 times a week. It can also be different windows that have the problem, sometimes it's the main window, sometimes it's the write mail window.

I'm working on a laptop with the second monitor changing often with different resolutions. Sometimes I have the impression that restoring the TB window on a screen that is different (smaller?) then the one where it used to be results in the full screen behaviour.

Versions:
Ubuntu 10.04.1 LTS
Thunderbird 3.1.6

Hit this. You can find the location in localstore.rdf where sizemode="fullscreen", and set it back to "normal", instead of just blowing away the thing.

I'll bite, changing the size mode in local store from fullscreen to normal solves the problem, Unfortunately I'm not sure what caused it in the first place..

Here is what I have found. First of all, I have Ubuntu 10.04 with GLX-Dock (Cairo Dock with Open-GL) installed on my system. My issue was caused when I installed the Cairo Dock add-on in Thunderbird 16.0.1, then I right clicked on my Thunderbird icon in my GLX-Dock and selected 'other actions - fullscreen'

After that, I did not get the option in the GLX-Dock, or in Thunderbird, to change it back to normal screen. What I found was that this changed the screen size settings in localstore.rdf to the following settings:

<RDF:Description RDF:about="chrome://messenger/content/messenger.xul#messengerWindow"
                   width="700"
                   height="403"
                   screenX="0"
                   screenY="3"
                   sizemode="maximized" />

I then changed filename of localstore.rdf to localstore.rdf.old and restarted Thunderbird. Thunderbird created a new localstore.rdf file on startup with the following default settings, which were correct settings to eliminate the issue.

<RDF:Description RDF:about="chrome://messenger/content/messenger.xul#messengerWindow"
                   width="1024"
                   height="711"
                   screenX="0"
                   screenY="3"
                   sizemode="normal" />

note: screenY="3" on my system because I have a hidden panel on top that is set to 3 pixels wide until I scroll over it. ScreenY would probably be "0" on most systems.

I just experienced this bug in current 13.04 alpha and solved it also by going to my profile folder to switch sizemode="fullscreen" back to "normal" in localstore.rdf.

This just happened to me on 13.04, I believe due to unity crashing. Editing sizemode="fullscreen" to "normal" solved the problem too.

Very nice analysis of this bug here too: https://bitbucket.org/mathematicalcoffee/maximus-gnome-shell-extension/issue/6/thunderbird-appears-maximised-undecorated

Well, I just had the same issue in Ubuntu 13.04, of course it didn't occur after a distro upgrade, I believe Thunderbird just updated, and I noticed compiz also crashed and restarted (updated @ night while I was asleep, and woke to find the error report about the crash, and all my windows were in a single workspace, which happens when compiz restarts). Then when I went to open Thunderbird it was fullscreen.

To fix this you can actually just delete localstore.rdf in the Thunderbird profile, if you want to be on the safe side just rename it to localstore.rdf.bak or localstore.rdf.old or something, then when you restart it and it creates the new file, and you're comfortable with it, delete the old file.

It is totally safe to delete though, because if it doesn't exist when Thunderbird opens it automatically creates it with default values (which is basically no values at all). Then when you change the size of the window to what you prefer, it will update the file with the appropriate values to remember how the window was.

And this is what's so amazing about text based configuration, in Window$ with a program that uses the registry for everything, you'd have to find the specific registry entry, and deleting it would likely break the program (and maybe even cause BSoD), so you'd likely have to find out what the key is and what value it's supposed to have.

Same here.
During upgrade from 13.04 to 13.10 I had some problems in compiz/3d acceleration/desktop elements (panel disappeared) and so on.
I was using thunderbird and it remembered the "wrong fullscreen" position.
After some tricks and updates my desktop was ok but thunderbird always started fullscreen, no matter what.
Editing the localstore.rdf from:
                    width="1539"
                    height="847"
                    sizemode="fullscreen" />
to
                    width="800"
                    height="600"
                    sizemode="normal" />
solved the problem.
Thanks all for the hints

Just happened here - Thunderbird 24, Gnome 3.6.2. sizemode="fullscreen" -> "normal" worked.

I just encountered this bug with today's Ubuntu 12.04 LTS

Just happened to me too. Ubuntu 14.04, Thunderbird 24.6.0. The workaround worked for me, but jeez what a frustrating and annoying bug!

Happened to me also. Ubuntu 14.04, Thunderbird 31.3.0. Workaround ok.

Things changed, now setting is in xulstore.json

Marco's note was the key for me. In my case some conflict between Compiz and Mate caused my desktop to go completely crazy. One of the effects was to make every application go full screen. After cleaning up the mess, all the apps went back to more-or-less normal but Thunderbird. I had already tried the localstore.rdf method without success. But Marco's note about using xulstore.json did the trick!

Until then, while I tried to get this working, the only way I could get to my Panel was by hitting F12, which brought up the miniterminal and coincidentally showed the Panel. But then I could only minimize Thunderbird. (And I ended up with a dozen or so miniterminal windows...) The right-click options on the Thunderbird button in the task list did not show Thunderbird as maximized. So the easiest thing was to just use File->exit in Thunderbird each time I tried things.
