can you please share details about your setup?

for example, can you share the content of the userChrome.css and the trydactyl configuration needed to bind 'b' with the toggle action?

As bovine3dom has mentioned already, b is the default keybind.

For userChrome, I use https://github.com/MrOtherGuy/firefox-csshacks/blob/master/c...

Not my GitHub, but incredibly useful repo for all kinds of userChrome shenanigans. Personally I keep it to a minimum (literally just this hack) so that I have less stuff to look at if an update breaks something.

b is the default bind for filtering and selecting tabs, so no configuration is needed there.

We offer some help with userchrome via `:guiset` which I personally use, but you should beware that Mozilla break it fairly often (maybe once every 6 months) with updates.
