Keyword -> multiple search engines, results in multiple tabs

[Adolf Stalin]

Is that possible?

For instance, I want to type "rfv speakers" in the search bar, press enter and see 7 tabs open, each one loading search results for the word "speakers" just like with a single engine keyword search. It would be VERY convenient.

Google that search string and you'll get 143,000 results. That should tell you why what you asking for is impossible.

There are metasearch engines which do that. You can access them from a bookmark, not a Firefox feature.
This is one that's been around many years: http://www.dogpile.com/support/Metasearch

I don't know if you can assign a keyword for that, but there is an extension that can do that and more.
It is called "Organize Search Engines".
Take a look at this post I made a few weeks ago, there is a video where I show briefly how it works, it has the option "Open All in Tabs" that does what you want to do (multiple searches on multiple tabs) but, again, doesn't have the option to assign a keyword to a multiple search.
Unfortunately, this extension is most likely to stop working in version 56, because it uses the old search bar.
