So I upgraded to Thunderbird 3 some time ago. It has nice new features, like the grouped folders. Anyway, there are a few things that annoyed me too; one of them being the fact that whenever someone sends a mail to me and some other people, only the first recipient was displayed, with a “more…” button next to it. The settings unfortunately do not allow to turn this behaviour off, but there’s a hack to do this (maybe in the future, they’ll include a setting…)
Step 1: find your messenger.jar file
Mac OS X:
Linux: I suggest you run
locate messenger.jar to find the file. You might need to run
sudo updatedb beforehand for this to work. It might be in /usr/lib somewhere.
Step 2: unzip it
You can either unzip the whole messenger.jar or just
content/messenger/mailWidgets.xml from this file, it’s the one we need to edit. On my mac, I copied the messenger.jar to my desktop, renamed it to messenger.zip, double clicked it to extract it, ending up with a “contents” folder on the desktop.
Step 3: edit mailWidgets.xml
content/messenger/mailWidgets.xml in your favourite text editor. Find
1 and change 1 to some higher number, like 10. This is line 404 in my file, I found it anyway
Next, we need to change the “true” to “false” in the “singleline=” line here:
<!-- multi-emailHeaderField: presents multiple emailheaderfields with a toggle --> <binding id="mail-multi-emailHeaderField"> <content> <xul:hbox class="headerValueBox" anonid="longEmailAddresses" flex="1" singleline="true" <-- change that to false align="baseline">
This will make lines wrap around that have too many addresses in it to be properly displayed on one line.
EDIT: This didn’t work for me
Save the file and exit the editor.
Step 4: rezip
I just right clicked the “contents” folder on the desktop and clicked “compress…” so OS X made me a zip out of it again, named “contents.zip”, which I renamed to messenger.jar. I just needed to copy the file back to its original path.
