Firefox コミュニティフォーラム

i cannot type the letter u in the search bar when trying to search something. i have been through all of the settings and i cannot figure out why it wont let me use the letter u. it pops up for a second then goes away or it autofills to a different link that im not trying to go to.

Whenever I open a new firefox window it opens to bing as my search engine even though I have bing unselected and removed from my search engines and google as my default browser for my account, I do not like using bing so if this can be fixed I would really appreciate it. When i open firefix for the first time after closing all windows it opens to my last tabs and stays as google but as soon as I open a second window its suddenly bing, I have triple checked my browser settings to make sure that google is still my default and that bing is removed.
