I can offer you css code to solve this problem until it gets fixed in TU.
Add this to a Stylish style (userChrome won't work):
Code: Select all
/*AGENT_SHEET*/
#tabbrowser-tabs .tabbrowser-tab[locked] .tab-throbber:not([busy]),
#tabbrowser-tabs .tabbrowser-tab[protected] .tab-close-button {
list-style-image: url(chrome://browser/skin/identity-icons-https-ev.png) !important;
-moz-image-region: rect(0, 16px, 16px, 0) !important;
}
The main problem seems to be this part of css in tabutils.css
Code: Select all
.tabbrowser-tab[locked] .tab-throbber:not([busy]),
.tabbrowser-tab[protected] .tab-close-button {
list-style-image: url(chrome://browser/skin/Secure.png);
-moz-image-region: rect(1px, 15px, 15px, 1px);
}
It points to a non-available Secure.png file. I don't know why it even works on Aero, because according to the path it should not. File a bug on TUs support area and probably suggest to include the padlock icon into TU package to avoid issues like that. I've pointed to an available padlock, but its green. Remove "-ev" from png file name for the gray one.
