User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; fr-fr) AppleWebKit/412.7 (KHTML, like Gecko) Safari/412.5 Build Identifier: I've been trying every combination of setting in userChrome.css but it seems impossible to change the maximum width of tabs. I know that there is an extension out there that can change the width of tabs (Tab Browser Extensions) but I really don't want to install that as it's way too buggy. It's possible to change the *height* of tabs, but not the width. Can this be fixed? Reproducible: Always

This code works for me. It changes a variable tab width to a fixed width. When the line is full it wraps: .tabbrowser-tabs > hbox { display: block !important; } .tabbrowser-tabs tab { min-width: 14% !important; }

This must be a Mac issue then - it doesn't work on the Mac version. I'm using the standard theme.

After spending a while to figure out how to get a tab to show up in the DOM inspector tabs have a class of tabbrowser-tab not tabbrowser-tabs. Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.9a1) Gecko/20051204 Firefox/1.6a1

My comments above are wrong. I made a mistake and removed the default namespace from userChrome.css. Once I added that back the Firefox build took the changes I made. WFM

Kevin, what exactly did you use to make this work?

after 20060121 Firefox Trunk Nightly Nuild / windows (after landed bug#308396). userChrome.css doesn't work. /* multiple lines of tabs */ tabbrowser tabs > hbox { display: block; } tabbrowser tab, tabbrowser .tab-icon, tabbrowser .tab-text { display: inline; } tabbrowser tab { width:110px; } Work fine up to 20060120 Trunk Nightly Build.

dazio in the Mozillazine forums discovered that tab width settings are being overwritten by tabbrowser.xml in toolkit.jar. A temporary workaround is to change lines 112 and 1111 in that file. Of course, you have to swap toolkit.jar files after every update. Here's a version with tabwidth set at 80px... http://pxclassic.net/toolkit.jar
