Just what I needed. Thanks a lot.

可以通过在about:config将browser.tabs.loadBookmarksInTabs修改为true实现该效果

Solved my needs, tab is where needs be. Thanks.

"Open bookmarks in a new tab" opens bookmarks in new tabs. Lovely!
Some reviews say new tabs open at the end, wanting them to open next to the current tab...
Changing "browser.tabs.insertAfterCurrent" to "true" in Firefox's "about:config" page seems to do the trick.

Does what it says on the tin, works proper!

Great! Thanks.

You saved my life

Simple. perfect, essential. Thank you Didier.

Thank you! This works really great for me. I'll never uninstall this firefox addon.

AVG's "Poorly rated browser extension found!" can go to the nine flames.

works great, thanks Didier! Would it be possible to open new tab next to active one? Now it always opens at the end...

Well done Didier Lafleur.
An "Open bookmarks in a new tab" that actually works in FF63.

All I need now is an "Open Links in a new tab". Cue >> Didier Lafleur.

I LOVE YOU!!!

so far worked lie a charm with no BS.
