Issues that I encountered with my Mozilla Thunderbird email 1) I had a bar just above my emails in the "inbox" (upper right) ("reply, forward, archive, junk and delete"). I inadvertently clicked something and the top portion of the bar became obscure-just very bottom of tabs showing. Trying to fix it, I made the whole bar dissapear. How do I get it back? (When I click on a "sent" email the bar is there). 2) In the process of trying to fix #1 I made the "menu tab" in the upper right portion of the inbox (tab with 3 horizontal lines) go away. How do I get that back? 3)Also in inbox start page I had a tab in upper left that said "WRITE" that I clicked when I wanted to compose an email. This also disappeared in my attempts to fix first issues. How can I get that back? Thank you
