FF version 54.0a2 (2017-04-18) (32-bit)
Almost every update prompt that appears has one of two or both of the following:
First and the most frequent is firefox opens two update prompts at the same time. Either one of them can be used to interact with, but requires the user to close the one in which he/she didn't interact with to perform the update. And second and also not nearly as frequently the update prompt comes up blank with only the title bar and buttons active with text labels the content that should appear in the rest of the dialog is missing. The buttons can be pressed and execute the relative task associated with them. I'm not sure if there is any diagnosis I can do on my end to help fix these but if there is please let me know what I need to do. Thanks
