Build ID: 20130909203154

Steps to reproduce:

Visit this link:

Actual results:

The link displays on the address bar with backslashes


Expected results:

Firefox should have substituted backslashes with %5C

Backslashes are not valid character in URIs. This behavior can cause problems when someone copies the address from the Firefox address bar and post it online.

After visiting the link, I then copied it from the address bar, and pasting it here shows it with %5C
https://en.wikipedia.org/wiki%5CFirefox

I think this is WORKSFORME.

But the link displays the wrong way.

I followed the same steps with the same results.
However when I copy and then paste it in a text box(without inserting it into the url bar and pressing enter first) the address remains as is i.e. without %5C.

Reporter, could you please be more specific with the expected results? Do you want to manually write the URL https://en.wikipedia.org/wiki\Firefox in the url bar, and, upon pressing Enter, Firefox to change it into https://en.wikipedia.org/wiki%5CFirefox?

I see the same behavior as in comment 2 on today's Nightly.
