How do I get rid of the vertical bookmarks that come up on every page
Everytime I open a Foxfire window it has a vertical bookmark on the right. I don't want to see it. Why did this suddenly start happening? It is annoying and my computer is running very slowly.
Additional System Details
- Shockwave Flash 32.0 r0
- User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:64.0) Gecko/20100101 Firefox/64.0
Could it be the sidebar? Is there an "X" to close the panel?
