This has been an off and on issue for me the past few weeks, but today has been particularly acute.
When I open a thread and go to the bottom to the box where one is to type a reply on a thread, I cannot access the box.
The text ‘Write something’ does not always appear in that box. Or it appears for just a moment, then disappears, and I cannot access the box. Clicking it in by touchpad or mouse, the page is unresponsive. Reloading the page which seems to work, although it takes multiple reloads sometimes. This behavior occurs whether I try to post from the end of the thread or if I select a specific post to reply to. I also have this problem if I start a thread–like this one. Had to reload the page three times to be able to actually type this post.
This is on a laptop, Windows 10, Firefox.
I suspect the issue is really one of slow loading of the page, probably as a result of the overwhelming volume of ads and ad trackers here. Unlikely the developers can/will do anything about that, but just in case it may be something else am posting this here.
