NoScript for Dillo makes no sense as it doesn't support JS anyway.
uBlock... yeah, a little, but most annoyances will be blocked by the lack of JS support anyway.
The plugins for Dillo are only protocol plugins; there are no file format plugins and no other kinds of plugins. However, I mentioned they should implement file format plugins too; other people also wanted this, and it does seem to be wanted enough that they might do it. (Other plugins will be more complicated to consider how to support it)
I tried the bookmark bar and could find no difference. The bookmark manager for FF seems far more advanced, with Chrome going the simplicity, beauty, and lack of information route.
Plus there are plugins for dillo... https://dillo-browser.github.io/#plugins
