Simple and working wonderfully.

A very simple yet useful addon. You simply copy a bunch of links from anywhere, and just click Paste and Go inside the browser, and all your links are opened. Its like magic. Also, no special bs permissions needed. Thank you dev for this gem.

probably best one out there for firefox. has a keyboard shortcut + toolbar icon.
as of july 2020 still works on version 60.0.2 too.

Tabs are open in reverse order when "browser.tabs.insertAfterCurrent" is true.

I like the shortcut which makes it feel like part of native Firefox: ctrl(or cmd)+shift+v (when the address bar is focused).

Sometimes takes time to open paste URL in new tab

Great add-on. All browsers should have this function.

I miss having a paste and search button. Is there any way you could get this add on to use default search on paste if no url scheme is used? Or i would even settle for another button. thanks.

doesn't work

Great idea!

My hopes were that it could be used for google searching, but that doesn't seem to work for me since it always seems to handle the pasted url as a web address

UPDATE: (Jan. 20, 2018)
I received a warning from my AVAST malware anti-virus that said this add-on (Multiple Past and Go Button) may track everything you do online. It may be a false positive, but perhaps the author can comment. (The plugin should only have access to the URL's you paste from your clipboard. That's what may be considered "tracking" by Avast, in which case it is not an issue. However, if the author transmits your data over the internet, or keeps your data in his private database, then that is an issue and a violation of privacy.)

As of Nov. 2017, v57 (Quantum), existing Firefox addons can EITHER copy OR paste, not both ( Until someone develops an addon that can do both). Thus we must find a replacement for Copy URLs Expert, or Copy All URLs.

SOME ALTERNATIVES
Here is what is working for me, now...

(1) Copy All Tab Urls WE (Web Extension)

> This only copies URL's

Combined with... PASTE URL's

(2) Open Multiple URL's

To answer your questions
I'm running Firefox 55.0.3

As for URLs there are many . Here are a few examples.

A list of zippyshare URL's on numerous occasions
A mixed list of music and storage sites (i.e. youtube, mediafire, zippyshare, discogs) etc

I even just tried the list of sites I have in my menu bar (ebay, amazon,imdb) etc . It failed too.

This is a generic problem and not url specific and it occurred when your add-on changed from 'legacy'.
