I use windows 7 ultimate 32bit and firefox final version. My display settings are 1680*1050 resolution and 200% dpi. The tab reorganizing by dragging from left to right etc don't work normally in this display settings. second problem is dragging favicon next to URL to the bookmark menu don't work perfectly. You can place two bookmark items in advance then try to place third. The pointer line is not in its normal position at the dragging. Third problem is about detecting screen resolution (1680*1050). the firefox detects it much lower. Maybe detecting as 800*600. You can know it by visiting many webpages. The Last problem is the toolbar menu including background persona image looks very blurry. Please solve all this display related problem in short time. == This happened == Every time Firefox opened == Changed display settings
