Yes, when there is one word, Firefox will try it with www. at the beginning and .com at the end (depending on your location). To prevent that, turn off the "fixup" feature here:

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the filter box, type or paste fixup and pause while the list is filtered

(3) Double-click browser.fixup.alternate.enabled to flip it to false. That should take effect immediately with your next search, and you can close this tab.

Thanks. It was already at false, but I switched it to true and then false again, and now it google searches when I type anything that is not an address.

I have the same problem, I tried jscher2000 and BabarSuhail's methods but still did not work. :(

Hi zuesuep, can you confirm that two-word searches work correctly? If you get the same error for both, reset the value of keyword.URL as described in this article: https://support.mozilla.org/en-US/kb/search-web-address-bar#w_changing-the-internet-keyword-service

To summarize:

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the filter box, type or paste keyword and pause while the list is filtered

(3) Right-click keyword.URL and choose Reset. Then test again in the other tab.

Any luck?

hi jscher2000, It's just the one-word search giving a 502 error, the multi-word search works just fine.
