When I post a thread comment, sign in, or take some other action that would lead to reloading a thread with new info, the thread displayed is always the previous thread visited.
For example, I posted a comment on Thread A, and had Thread B open in a new tab. Once the page reloads after my comment post, Thread B is now open in the tab that previously displayed Thread A.
I'm using Firefox 14 with no add-ons that would seem to cause such behavior. Anyone else noticing this?
Note: this happened again when I created this thread. After submitting my post, I was redirected to the "Beautiful Site Design" thread which I had open in another tab, instead of being shown my own post.
