When you search for something with DuckDuckGo, click on a result and
then click on your browsers back button you end up at DDGs start page
and not the results page.

1. Enter "guix" in your search/address bar while having DDG as default
search engine.
2. Click on first result -> guix.gnu.org
3. Now click after landing at our beautiful website on the browsers back
button (<-)
4. You end up at https://duckduckgo.com/?ia=web and not at
https://duckduckgo.com/?q=guix

This does NOT happen when you
1. use DuckDuckGo in Chromium via it's address bar
2. use DDG in Icecat starting from duckduckgo.com and not the
address/search bar
3. use Bing or Google via Icecat's address/search bar

I have disabled the "Spoof Referers" setting which comes from Icecat and
is available at about:preferences#privacy

Icecat has some custom DDG search plugin:
https://git.savannah.gnu.org/cgit/gnuzilla.git/tree/makeicecat#n172
https://git.savannah.gnu.org/cgit/gnuzilla.git/tree/data/searchplugins/duckduckgo.xml

Maybe that's breaking that. I don't know.

This was already reported upstream here:
https://lists.gnu.org/archive/html/bug-gnuzilla/2020-02/msg00000.html.
Another user reported the same behavior wwhen using Tor browser.  It
seems to be an issue with DDG itself, where their HTML only website
breaks when Javascript support is detected.

You can verify this by re-enabling LibreJS in Icecat; it'll suddenly
start working again.

Okay, go back does work on https://html.duckduckgo.com/html?q= when
enabling LibreJS.

But their search doesn't break in Chromium or in upstream Firefox. So I
guess something is wrong with our Icecat/shipped search addon.
