781427 - When the site address's url contains a param, which value is chinese character, then the url will change to a weird one.

Status: RESOLVED DUPLICATE of bug 775072

(Firefox :: Address Bar, defect)

Description

[sunnylost]

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:14.0) Gecko/20100101 Firefox/14.0.1
Build ID: 20120713134347

Steps to reproduce:

make sure the "browser.urlbar.autoFill" is TRUE.

1,type this url in the address bar "https://www.google.com.hk/#hl=zh-CN&newwindow=1&safe=strict&site=&source=hp&q=%E5%95%8A"
then you will see "https://www.google.com.hk/#hl=zh-CN&newwindow=1&safe=strict&site=&source=hp&q=啊", Google will add some other params at the end of the url, so finally, it will looks like this "https://www.google.com.hk/#hl=zh-CN&newwindow=1&safe=strict&site=&source=hp&q=啊&fp=f389c5f761e0798d"

2, remove params which at the end of character "啊", hit enter.

3, repeate above steps several times(i try this for 3 times, then i got the answer)



Actual results:

address bar will show url like this: "https://www.google.cgoogle.com.hk/#hl=zh-CN&newwindow=1&safe=strict&site=&source=hp&q=啊"

when I turn the "browser.urlbar.autoFill" to FALSE, this problem was solved.


Expected results:

So I think this may be caused by the "firefox 14' address bar autofill" mechanism.

This sounds like a pretty unfortunate user-affecting regression that we'll want to try and get a fix for this into Beta if possible.  I would assign this to Marco but he's away until the 12th so passing to Gavin to determine who might be able to take this on.
