Also just noticed the same problem in Firefox.

One other maybe relevant factor: I've got a 64-bit Thinkpad T420, but my Lubuntu is 32-bit. But that doesn't seem to affect anything else.

Thanks,

ISTR reading that the developer of that add-on had ceased support for Linux. I am surprised that it went as far as letting you download the add-on.

I set my Thunderbird GUI font typeface and size via a userChrome.css file now.

OK, so color me embarrassed, thanks for the reply!

All I want to do is increase the font size of the summary blocks for the inboxes/sents. Is there a simple way to do that at?

Bill

I use a simple global one-size-fits-all setting, but I am sure that it can be adapted to apply specific fonts or sizes to particular parts of the display. I'll have to get back to you on this, but in the meantime if you search for thunderbird style css userChrome.css you may come up with some answers for yourself.

I'm drawing a blank with that search: I haven't the foggiest idea where I'd put that .css file.

Thanks!

Bill

perhaps this will help with that location http://kb.mozillazine.org/index.php?title=UserChrome.css&printable=yes

Getting warmer, but I'm still a little confused. I'm trying to change font size in *thunderbird,* but i'm going to create a chrome folder here?

/home/bill/.mozilla/chrome/

Then put the userChrome.css file in there, or does it go in a subfolder in .thunderbird, ie,

/home/bill/.thunderbird/xxxxxxxxxxx.Default User/chrome/

where xxxxxxxxxxxx is my main thunderbird profile name?

Thanks,

Bill

Those mozillazine articles refer also to Firefox and SeaMonkey so paths can sometimes be confusing.

It will be a sub folder of your Thunderbird profile folder. The easiest way is click the troubleshooting information on the help menu and in that click show folder. In the folder that is displayed, create the chrome folder (note case is sensitive) then add the userChrome.css file to that.

OK, so I created a /chrome subfolder in my profile folder, then created a userChrome.css file that looks like this:

/*

* Make all the default font sizes 20 pt:
*
* * {
*   font-size: 20pt !important
* }
*/

and put in that ....../chrome/ subfolder.

but my summary block font still looks the same.

Did I miss a step somewhere?

restarting Thunderbird?

Anything between /* and */ is treated as a comment. So…

/*
 * Make all the default font sizes 20 pt:
 */

* {
   font-size: 20pt !important
}

In this case you might format it thus:

* { font-size: 20pt !important }

Yes you definitely need to close and restart Thunderbird.

Actually, you ought to close Thunderbird before doing any of these changes. Some files will be re-written by Thunderbird when it closes, potentially undoing your hard work.

IIRC you also need the namespace declaration, below, as the first thing in your userChrome.css file. So the whole thing would look like:

/*
 * Do not remove the @namespace line -- it's required for correct functioning
 * set default namespace to XUL
 */
@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); 

/*
 * Make all the default font sizes 20 pt:
 */

* {
  font-size: 20pt !important
}

Are you using the Mail Summaries add-on? It ignores these settings. :-(

YES!!!

Not sure whether it was the longer file suggested by Zenos or simply editing the file with T-bird closed, but I've now got a summary file I can read!

Thanks All,

Bill
