User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:32.0) Gecko/20100101 Firefox/32.0 Build ID: 20140830211128 Steps to reproduce: 0. Make sure you’re using Firefox on Linux, v32+ (including the latest nightly). 1. Go to about:config. 2. Set browser.urlbar.clickSelectsAll to true. 3. Append ‘:’ (without the quotes) to the location.* [*] This issue is also reproducible for uppercase letters, or any character that requires Shift. Actual results: The location bar shows ‘:’ . Expected results: The location bar should have shown ‘about:config:’.

I'm not able to reproduce it with FF32+ on Win 7.

That’s because this regression happened only on Linux. (It also worked for me in Windows XP.)

It must have happened recently, between 31 and 32. Checking nightlies, I managed to track down the first occurrence of the bug to 2014-05-28[*]. [*] This is build I used: http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2014/05/2014-05-28-03-02-19-mozilla-central/firefox-32.0a1.en-US.linux-i686.tar.bz2

I'll try to have a look tomorrow. If my assumption is correct, the regressing bug would be somewhere in: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=cbe4f69c2e9c&tochange=e017c15325ae

I'm struggling to reproduce this. Your steps are not clear about how you focus the location bar and how you "append" - if you modify the pref, and click in the URL bar, the location bar's entire contents are selected, and so entering any character replaces the selection. That seems expected. If I click in the location bar or use ctrl-l, and then use the right arrow key to stop selecting content and keep the cursor at the end, and type ":", that works for me and appends ":". Tested against current nightly. What am I missing?

What am I missing? Yes, I meant typing the shifted text when nothing is selected. This bug happens wherever the cursor is, whether at the end or in the middle. I tested this on an Ubuntu LiveUSB, and the bug did not occur. However, upon installing the operating from scratch and updating, the bug returns (both on the current version and on the 05-28 nightly). I also made sure to uninstall Ubuntu’s Firefox extensions, to make sure they weren’t the culprit. So, I have no idea why the bug didn’t occur on a LiveUSB. I guess you need to be on an updated Ubuntu x86 system in order to reproduce this.

I have have *finally* figured out the cause of this bug, and it’s not a Firefox issue. This was caused by having Shift+Shift set to switch layouts in Ubuntu. Changing that fixed the problem completely. It even fixed some issues I was having with Nautilus. Therefore, it seems to be an Ubuntu/GNOME bug. I will close this issue now. Thanks for your help!
