Long time user of Firefox (since its release in 2004) but just recently started looking into the use of themes even just for the fun it can add to a day. For whatever reason I am drawn to DARK settings recently across everything from my os (mac and win) to browser(s) (FireFox, Edge, Chrome) to app settings which allow me to change appearance. The Dark just seems to feel better for some reason. Which lead me to finding this them as I installed probably 20+ different ones I found just searching the themes section for the Mozilla addons site for the keywork dark and noticed the very first listing under "Recommended themes" was Spaceship with its 5,691 users so I checked it out and upon install the first thing I noticed was the tagline "This theme brings the thrill of piloting a spaceship to your Firefox browser" which of course immediately awoke and brought to attention my inner 6 year old Calvin who of course started feverishly and repeatedly clicking through the sparse hamburger menu and gearbox icon options within the themes settings desperately looking for that one sure to be hidden radio button which would fire-up the turbo rockets and finally launch the settings menu to be able to control the fucking Spaceship......alas even after multiple rounds of disabling, removing then reinstalling and enabling and looking behind the couch of the 38th time for that damn radio button I finally gave up. It was all a lie, there is no Spaceship I can pilot transporting me to the final frontier. The only reason I am leaving this review is to hopefully save countless others the 20+ hours I spent looking for the hidden radio button. IF for any reason I might have missed it and someone can point me in the right direction PLEASE PLEASE PLEASE post a review hear and help the rest of us out...OK?? And I am giving the Theme a 4 out of 5 starts based on the simple fact it is Dark and I DO LIKE DARK and one other little thing is that somewhere in my time spent on Google doing research on the theme and this Kosmo fellow who designed it thinking maybe there was an Easter Egg in the themes settings I was missing and maybe I could find someone else posting about it online somewhere I came across a recent news article about this years release of the Firefox based browser called Zen (zen-browser.app) and a little birdie told me they might have an actual Spaceship built in.....

Its fully developed, and doesn't look bad. At the same time, it doesn't go the extra mile and color parts of the browser interface that other themes do, and though it doesn't look bad, it also isn't great.

Really like the red box that highlights the current tab. Great feature.

sehr schön!
