Neil's suggestion to avoid using ODM for updating WB caught my eye. The titlebar issues with FF & PM were reportedly 'fixed' with 8.09 but persisted on my rig after updating to 8.09 using ODM. I remembered I really want to keep the installers saved so this time I D/L'd the installer from my account page and installed using it, which actually did fix the issue. So maybe Neil is on to something.
I don't use OD Manager at all. I downloaded the installer. First time didn't work; still showed the old version number. I had to uninstall WindowBlinds, reboot, and install the new version. Got the right version number then, but Firefox and Waterfox crash on launch.
