Ctrl + click on bookmark / link opens new tab.
A-ha! I discovered this quite by accident when it didn't do anything upon clicking on a link and mis-timed a keystroke!
And so... it works a charm now.

Works well. If using FF57 and you want to open bookmarks in new tab you don't need an addon. You just go to about:config and turn browser.tabs.loadBookmarksInTabs to true

Totally Not work for me, dunno why, hope the updates can fix it.

As many users I would like to have the feature to open bookmarks/url bar/ in a new tab. I used tab mix plus until FF57 arrived and the possibilities to decide what is opened in a new tab was my favorite feature.

This one is very good start, 5 stars when the above options are given.
Thx!

1. Doesn't open Bookmarks in new tab
2. Doesn't open some links within a domain in new tab even though I set it (in options) to open ALL LINKS in new tabs

In other words, it doesn't work and I'm looking for an alternative plugin.

I wont to new tab from bookmark bar.
this addonn can't open new tab from bookmarks.

works great with all links, thanks!

I'd like to add my voice too....that this extension won't truly be the best until a bookmark will also open in a new tab. Please add it! Otherwise, thank you very much, its great so far.

If possible please add open new URLs entered in location bar into new tab without holding down any other keys/mouse buttons

please make bookmarks open in new tab

Like many have requested, why can't this be setup to also work with URL and bookmark links? Having a URL link open in the present tab, which is already occupied with a page that I still need, is really annoying.

I will revisit my # of stars should this essential aspect be added.

Great to have this functionality in FF 57! Thank you. Works as expected. One request, and I don't know how difficult it is, would be to have links from the urlbar open in a new tab with a different shortcut, or by default. Can't figure out how to do that!!

Does exactly what it needs to do

It does what it is supposed to, most of the time.
I had an issue with trying to log out of google. It kept opening a new tab when I clicked Sign Out, leaving the old tab still logged in.

I would also love to have an option to open new tabs on the right of all other tabs.

I'm very happy that someone has given us a semi-replacement for a Tab Mix Plus (RIP) feature.

Works well, except for Duck-Duck-Go, where clicking a search result link replaces the results page rather than opening a new tab.
Only page like that I've found so far.

TreeStyleTabと同時に使った時､新しく開かれたタブが"子タブの階層の一番上"に作られます
"子タブの階層の一番下"に作られる方が自然だと思います
私はそっち派なので､下の方に作られるようにして欲しいです
お願いします

Nice and usefull idea, but it should although be possible to configure it, that links opened from Bookmarks (e.g. sidebar) although opend in new tab

Works well. Would it be possible to add another option: "Open new tab in background"? Such that when I click on a link, the tab opens in background and I have to click on the new tab first to switch focus from current tab to new the tab?

最近（2020.8）　新しいタブは開くがリンクが開かない・アドレスバーにはアドレスが入っているが。一度リターンを押さなければ開かない、という現象が頻発しています。

追記：２０１８．５　FEEDLY との相性の問題は他の方も指摘しています。原因がわかれば対処お願いいたします。

「他のサイトへのリンクは新しいタブで」機能が使いたくて、とても便利に利用させていだいています。

ただ一つ不具合があります。　RSSリーダーの FEEDLY で、ログインができなくなってしまいます。原因はよくわかりませんが、このアドオンを外せばログインできるので、このアドオンとFEEDLYの相性が悪いのだと思います。
以前のバージョンでもこの問題が発生しており、しかたなくTAB-MIXを使っておりました。

もし可能でしたら対応をよろしくお願いします。

This addon does exactly what it says it does. It open links in new tabs. Not bookmarks - there's a preference for that (set browser.tabs.loadBookmarksInTabs to true; you may need to create it as a new Boolean setting if it doesn't already exist). Not searches - there's a preference for that too (browser.search.openintab - also set it to true). Just links.

Like many others I do wish it would open addresses typed into the address bar in a new tab, and it would be wonderful of the developer could do that, but it's unfair to give him a low rating for not doing something the addon is neither designed no claimed to do. So, I give it five stars, because it is working exactly as it's supposed to for me in Firefox 57.

Helps restore tab control available in legacy Firefox

必須機能です。新Firefox対応版非常にありがたいです。
ブックマークの方もリリースされたらもっと嬉しいです。

シンプルながらも 必要度の高い機能です。作者さんが日本人なので 表題、説明が分かりやすくて良いですね
ブックマークを新しいタブで開く拡張も作って下さい。
