I entered a search query into the Firefox search box. I selected the duckduckgo.com search engine. Instead of any useful results I was redirected to a blank
html.duckduckgo.com/html. I had to repeat the search request.
I have been using duckduckgo for many years. Why the change?
I tolerated this behavior for some days and then dug into resolving the problem.
I suspected the problem would be resolved by editing the
duck_duck_go.xml search engine file, but I hadn’t messed with Firefox search engines in a long time.
After poking and prodding I found my bearings. Updating was straightforward only because long ago — before the Mozilla developers moved to their pseudo proprietary mozlz4 compression nonsense — I preserved copies of my search engine XML files. Back in the day when creating XML search engine files was easy. All of my XML search engine files are stored in
template= field in the
duck_duck_go.xml file to use
html.duckduckgo.com/html resolved the problem.
