I didn't mind this bug in about a week ago, but it is sufficiently annoying enough. The firefox is deleting last letter consists of my locale, hangul, when I search it through address bar. It occurs when searching more than 2 words. Precisely, conditions are two. 1. one or more space bar between two words. 2. the last word has more than one letter. ex) ㄱ ㄴㄷ(enter) --(when searching through address bar)--> ㄱ ㄴ It is resolved by adding space bar or move the cursor to the right of the letter. So you can't reproduce it with just copying that words. You need to search with korean locale keyboard to reproduce that bug. Anyway, it's still annoying doing things what I should not do with the previous version.
