[trinity-users] firefox esr 60.5.0 won't start - "using gtk+ 2.x and gtk+ 3 in the same process is not supported"

(firefox:25111): Gtk-ERROR **: 06:31:04.907: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported ExceptionHandler::GenerateDump cloned child ExceptionHandler::WaitForContinueSignal waiting for continue signal...25117 ExceptionHandler::SendContinueSignalToChild sent continue signal to child (crashreporter:25123): Gtk-ERROR **: 06:31:04.956: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported This happens to me on Buster with 14.0.6 whether using the .deb or the mozilla.org build. Google hits mostly seem to point to building various apps rather than simply using them. On Tubuntu 18.04 the same mozilla.org firefox-esr-60.5.0 built works fine, other than the UI mousetype which is upstream GTK fault. Anyone else have this problem? -- Evolution as taught in public schools is religion, not science. Team OS/2 ** Reg. Linux User #211409 ** a11y rocks! Felix Miata *** http://fm.no-ip.com/
