Hello Don,
Thank you for submitting this bug and reporting a problem with Firefox.
You made this bug report in 2012 and there have been several versions of
Ubuntu and Firefox since then.
Could you confirm that this is no longer a problem and that we can close the
ticket?
Or, if it is still a problem, could you run the following (only once):
apport-collect 947421
and upload the updated logs and and any other logs that are relevant for
this particular issue.
Thank you again for helping make Ubuntu and Firefox better.

Title:
Unicode in URL bar produces unexpected results
Status in firefox package in Ubuntu:
Incomplete
Bug description:
Today I tried to copy a URL from a Thunderbird email text and then
paste that URL into the Firefox URL bar. Instead of loading the URL, I
was sent to google search with the URL as the search parameter. In
other words, Firefox interpreted my pasted text as a search phrase,
not a URL. When pasted in the URL bar, I saw:
http://www.example.com/sample/url.html (actual URL redacted for
privacy reasons)
Typing the URL in manually sent me to the correct location.
Further investigation revealed that my copy attempt inside Thunderbird
picked up a stray unicode character at the beginning of the URL. The
original email was sent with Content-Type: text/html; charset="utf-8"
and when I pasted the copied text into a plain text editor (vim), I
saw the following:
<200b>http://www.example.com/sample/url.html
where <200b> registers as a single character in the window.
(U+200b) appears to be "Zero Width Space"[1], and I believe that
Firefox is interpreting this as an invalid URL charcter (which it is)
and treating the string as not-a-url.
This is unexpected behavior because (U+200b) is invisible unless you
look carefully after you paste. It is possible to avoid copying the
unicode character at the start of the line, but it requires more care
than most people take when selecting text. The fact that the URL
appears to be perfectly correct in both the URL bar and the google
search bar (after the search completes) is confusing to the user: "why
did I end up here? Why didn't Firefox just load the URL like I told it
to?"
I realize that this may cause other issues in the future surrounding
internationalized domain names and URLs, and I don't really have a
suggestion for how best to handle this: unicode isn't my specialty. I
would like to suggest that the best path forward should accomodate the
need to use internationalized URLs without causing unexpected results
like this.
Just in case the "Report a Problem" didn't pick this up, I'm running...
