This add-on is wonderful!
It's always bothered me that, when I "Open all Bookmarks" in a folder, FF tries to load all of them at the same time.

It's a must! After more than twenty years and more than a hundred versions, Firefox is still lacking this indispensable feature ("open in a background new tab") in the contextual menu of the links! The feature exists via Ctrl+Shift+Click but it still doesn't exist in the menus! Incredible but true!

And not only does this add-on offer that sorely lacking “Open this link in a background new tab” menu, but it's also in deactivated state as long as you don't visit the tab!

That's great!

One of the most useful add-ons I've ever had - thanks!

Worked perfectly as I wanted it, so far. Played nice with sidebery and with Firefox's new vertical tabs.

It works wonderful! I use it in blacklist mode.

Does not work in Firefox 121.
Please fix this.

Good!

Excellent for old machines.

Are you the dude on the superuser forum asking how to do exactly what this add-on does? So basically you didn't find what you were looking for, so you learned to code addons and made it yourself? If so, you are a golden god; mad respect. We need more people like you around. You helped me save my over 2000+ tab session that just decided to roll over and die. Thank you so much.

It does the job it what made for. Thanks !

Works as advertised. When you Ctrl-click a bookmark folder, all the tabs in it open but do not load until you click them. Similar to HoldTab extension, and the former Load Tab on Select.

It works. That may not sound like high praise, but nearly every other extension I've tried of similar functionality always found some way to conflict with Firefox and otherwise work in unwanted ways.
