#HELP
Whn viewing mastodon in a browser, if I browse the 'home', or 'local' or 'all' timelines, I can enter a post for a closer look, and hitting the back button will take me back to exactly the same place in the timeline.
If I browse 'explore', when I hit the back button out of a post, I'm deposited a mile back in the timeline. And its REALLY FRUSTRATING.
Anyone else suffer this? Any ideas?
BTW, using Firefox v121
