Long story short, before the latest FF update 62.0, when I started typing an letter or two in the address bar, I used to get my desired website link on the top of it. Now, I'm not sure what happened but now I'm getting probably the most visited website link rather than the preference given as earlier. I have to type nearly half the website address or sometimes even the complete one to get the actual web address I'm trying to access, this is getting irritating. Even bookmarks aren't give the top preference over the most/latest visited link. for example, when I typed - mo, I used to get mozilla links in the address bar drop down list - I just had to open the link I was interested in, now I have to type nearly the entire word, to even get the list related to that specific website.
