I’ve had this happen a few times already. If I leave a lemmy tab open and do something else after a certain amount of time, I find my system starts to bog down. After checking task manager I find that all system memory is being used up by my browser(Firefox). Never had this issue until this week. I think this issue is related to how new posts keep loading in the feed.
I don’t know if this is just lemmy not working with Firefox or a lemmy specific issue.
I’m seeing the same thing, also in Firefox but I suspect it’ll happen on any browser. I’m with you, I think it’s because it keeps loading in new posts but doesn’t unload the old ones. It’s probably an easy fix
