Why does the "go to new post" function via email get stuck?

I use email notifications to keep track of threads I’m interested in. Most of the time, if I click on the link in the thread to go to the new posts in a thread, it will take me back to some point earlier in the thread. It will stay on that point perpetually. For example, in one thread I’m participating in, it’s post 165.

Why does this happen and can it be fixed?

I’m using Firefox.

What’s an example of a link?

The one for this thread looks like this: http://boards.straightdope.com/sdmb/showthread.php?t=733686&goto=newpost

Moving thread from General Questions to About This Message Board.

The only suggestion I have is to try clearing your browser cache.

It’s just a wonky calculation between cookie information and the board software and what is “new” versus what is “new to you” and … it’s complicated, and I’m often surprised when it does work.

Shitty answer, sorry.

I don’t mind knowing that there’s not an easy fix I’ve been ignorant of all this time. Thank you both.
