Let's say I open a webpage with some Unicode characters, say, Cyrillic, in the address like this:


When I try to copy it from the address bar somewhere else, it becomes unreadable rubbish:


I guess this is for compatibility. However for readability I want to copy it straight away with proper Unicode characters.

What and how should I tweak to make that possible?

Edit: The answers are good, but they are hacky. Are there any settings in about:config?


The setting was replaced with browser.urlbar.decodeURLsOnCopy in Firefox 53+. Set it to true.

For copying in Firefox on Android see https://android.stackexchange.com/q/224951/17612

    It works only in url-bar, if I just copy link from web-page and past – I still get %-things. Does Firefox have addon like Chrome's?

  • @stegetsj I'm not aware of such extension, unfortunately. I don't think I'll use it but if you find one and post it as a separate answer I'll definitely upvote it.

Try setting the network.standard-url.escape-utf8 option via about:config.

Possible values and their effects:

  • true - Escape UTF-8 URLs. (Default)
  • false - Do not escape UTF-8 URLs.

Yes, browsers do that -- it's URL encoding and actually a quite useful thing.

I see two choices

  1. Copy only a fragment of the URL, it will not be URL encoded.

  2. Decode the URL encoding. In Unix, you can open a terminal, and type

    echo -n -e "$(echo http://ru.wikipedia.org/wiki/%D0%A4%D1%83%D0%BD%D0%BA%D1%86%D0%B8%DB0%D0%BB%D1%8C%D0%BD%D0%B0%D1%8F_%D0%B7%D0%B0%D0%BA%D1%80%D0%B5%D0%BF%D0%BB%D1%91%D0%BD%D0%BD%D0%BE%D1%81%D1%82%D1%8C | sed 's/+/ /g;s/%\(..\)/\\x\1/g;')"

    This should be the default answer.

    Your idea regarding copying a part of the URL is extremely helpful! (especially because on my FF v50.0, the about:config setting did not change anything). Regarding the second option you wrote, Is there a command for Windows users too?

It's not rubbish, it's URL encoded. However here's the trick:
You can edit the URL in the address bar (by adding and then removing a character), and the copy-pasting should preserve the encoding.

  • Interesting "trick". Seems to work in Firefox v.32, however unfortunately not in Chromium v.37 (~ Google Chrome). Or does it? Sep 9 '14 at 13:28
  • @nuttyaboutnatty works for me in Chromium 76.

Use this key sequence to copy UTF-8 URL:

Ctrl-L, Home(or End), Space(or a letter/symbol), Backspace, Ctrl-L, Ctrl-C
  1. Copy the URL from the address bar

  2. Paste it here.

  3. Press the Decode button.

  4. Copy the decoded URL and use it elsewhere.

    Too complex to just copy the URL by Ctrl+L, Ctrl+C without touching the pointing device.
