This same bug is happening to me on Firefox version 115.0.2.

Works fine for me on Firefox 115.0.2

I see this happen too with trends but it's only occasionally and not every time. Also, opening a new twitter tab from clicking a profile or link sometimes does not fully load the extension for me.

Can verify that toggling Trends/Who to Follow also doesn't save for me on Firefox Nightly 117.0a1 (20230726093921). Preset fonts do save correctly but I haven't tried custom fonts. I ended up just using the uBlock Origin element picker which is working for now.
