Tor Network Settings button feedback
On about:torconnect
, the button labeled, "Tor Network Settings," should be a hyperlink to "Tor Network Preferences". Hyperlinks display content. Buttons perform a command. It should say "Preferences" instead of "Settings" to keep jargon consistent and identical to the label of the menu item and its pages. Consider prepending the gear icon of the Preferences menu item to the hyperlink.
If you want a button, its label should start with an imperative command word like "Configure", and since this widget opens a panel that lists multiple preferences, the label on a button should end with an ellipsis like "Save As..." or in this case "Configure Tor Preferences..." Or if you want minimalism, you could reduce it to a button with just the gear icon, but new users might not understand what the icon means if there isn't text. The color of the button could be more contrasted against the background for visual accessibility.
