Note that this is probably a configuration issue, not a defect per se. Still, 
as I'm not the first to be affected, I think it'd be useful to have the 
solution recorded somewhere.

Yes I've seen similar problems like this and it is usually due to an incorrect 
configuration of the plugin.

To configure the plugin correctly you just need to enter in the path used for 
your webui interface in the correct places.
As an example lets take someone who uses a uTorrent server that opens the webui 
with the path:
https://www.myserver.com:3282/gui

For this example you would enter the options as follows:
Server Address dropdown: https://
Server Address: www.myserver.com
Port: 3282
WebUI Path: /gui/
Username: as required
Password: as required
BitTorrent Client: uTorrent

Give that a try and let me know if you still have a problem.

Thanks. I've double-checked:
- the data in the WebUI+ plugin matches the data I've set on uTorrent. 
- I've tried various combinations (default port/alternative listening port, 
shorter username and password)
- the server is on my internal network (http://10.0.1.198)
- When I select 'open WebUI' from the WebUI+ plugin, the page is opened 
correctly. 
- clicking on a magnet link still results in  'Error 400'.

I've created a new Firefox profile, and the plugin works in this profile. So in 
my case it's likely another plugin interferes with WebUI+. I use plugins to 
block ads, cookies etc, one of those might be the culprit.
