I don't know if this is related to the other difficulties, but using a recent Mozilla Nightly Build - 2002092617 - over the past couple of days I occasionally enter a forum, read some stuff, then click on the Back button and an Alert box with the error above pops up. Repeated attempts also fail. I have to click on the forum name between the thin lines to get back to the forum root to mark the forum read.

It has happened in at least 3 forums, but it doesn't happen all the time.

I'm using Privoxy, but nothing related to IWeThey is blocked.

Is it something on your end, or something with the Mozilla build? Do others see this?

Thanks.

Cheers,
Scott.
