[CentOS] aggravations of t-bird 10

a) I do not run gnome. I will *NEVER* voluntarily run gnome. I don't even want it installed. b) Click on link in an email in t-bird, and get this in the error console: Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIExternalProtocolService.loadUrl]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: chrome://communicator/content/contentAreaClick.js :: openLinkExternally :: line 188" data: no]

I *used* to be able to fix their True Religion crap by editing /usr/lib/thunderbird<whatever>/open-browser.sh, but that doesn't fix it.

Clues for the poor?
