Korean Language Input Error on Address Bar When Using Search Shortcuts


(Firefox :: Address Bar, defect)

Firefox 83

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:83.0) Gecko/20100101 Firefox/83.0

Steps to reproduce:

I experienced the issue for the first time on November 22nd, 2020. In other words, probably the latest update is causing the problem. The address bar omits the last two or three keyboard inputs when the search shortcut is used. For instance, I set "ddg" as the keyword for Duckduckgo search shortcut. I type "ddg 파이어폭스" on the address bar and hit enter.

Actual results:

The browser shows the search result for the word "파이어폭" (which omitted the last letter consisting of three inputs) on Duckduckgo. It seems like Firefox ignores the inputs made for the last space. Sometimes instead of omitting the inputs, the browser simply ignores the search shortcut function. In that case, I see the search result page on Google (which is my default search engine) for the keyword "ddg 파이어폭스".

Expected results:

I should have seen the search result page for the full word "파이어폭스" on DuckDuckgo.

The consequence of this bug is that users cannot use Search Shortcuts when searching for Korean words.

I'm on Firefox 83, Windows 10.

Thanks for your attention.

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

Component: Untriaged → Address Bar

Reproduced with Korean keyboard under Win 10 64-bit using Firefox 83RC, 84 beta 5 and latest Nightly 85.0a1. This only happens if Search Mode is entered before starting to type.


  1. Focus address and select an engine to enter search mode
  2. Start typing and press Enter - searched term is missing last character

If the string is typed before entering search mode, the issue doesn't reproduce.

Another issue is that address bar dropdown panel is open/closed on each keystroke.
