WFM here with the latest Nightly.

Try in safe mode then with a new profile, please.

I confirmed it in both safe mode and with a new profile. 17.0a1 (2012-07-31)

Comment 3

I hope it is clear from my description of the problem that the history must contain a URL to be edited.

Comment 4

The problem doesn't show up with all URLs, so try the following steps:

1. Visit http://whois.domaintools.com/206.83.48.110, http://whois.domaintools.com/66.87.121.59, and http://whois.domaintools.com/143.111.80.29.
2. Open a new tab and type whois.
3. Arrow keys on your keyboard to select a URL from a list presented to you by the location bar. Do NOT press Enter. The cursor will be at the end of the URL.
4. Press Ctrl+Delete.
5. Observe that the last part of the IP address in that URL gets selected instead of getting deleted.

You could also reproduce this bugzilla's URLs pointing to tickets.

Thanks for the STR, I'm able to reproduce it.
Anyway there is a similar bug but with letters, see bug 775144.

Mozregression range:

m-c
good=2012-07-27
bad=2012-07-28

Comment 7

[Roman R.]

You are correct, Loic, bug 775144 describes the same bug and mentions another aspect of it.

Comment 8

[Roman R.]

By the way, the other bug report mentions FF's build that is earlier than the one you identified as good, 2012-07-27. He reported the problem in 2012-07-18, and I also remember experiencing the problem for a quite a long time (a few months, it seems).

Comment 9

Interestingly, there's bug 246237, which was filed many years ago for Firefox 1 (yes, 1!) and describes EXACTLY the same problem that has appeared relatively recently (in the last few months). It seems like somebody has copied a buggy piece of code and used it in the recent versions of Firefox.

The weird thing is I'm not able to reproduce your STR with a fresh profile (by using mozregression) and nightlies before 2012-07-28 (the 1st bad nightly).
