I guess we cannot control it. If you are removing some elements from layout, there is no guarantees that the rest will stay on its place. I mean, it's the same situation as with element hiding rules, if you remove something, all the rest could be messed.

The point is that for some reason it works differently in the Win/Mac versions and in the FF extension.

I suppose we may be damaging HTML in FF, and we need to find out how exactly.

Here's what you need to do:

1. Use this rule in AG for Win/Mac and in FF extension
2. Compare the resulting output (I guess you'll need to log what you've got)

Okay, I got it finally!

That's serious indeed:)
