Help needed: sdk/places/bookmarks search function seems not to be background / worker?

[Ruben Goethals]

Hello,

Can someone confirm that the search function to search for bookmarks is interrupting the UI and thus when having a lot of bookmarks is quite user-unfriendly?
See the relevant part of my addon's code below.  It makes firefox unresponsive for sometimes 8 seconds! (I have 3000+ bookmarks and 500+ tags).

And if so, should I make my ow worker for it or will it remain the same as I have read in the doc that workers use the same process? But maybe a seperate "process" is not required to be able not to interrupt the UI?

Great thanks if anyone has some info about this.

const { search }        = require("sdk/places/bookmarks");
/*
 * Other code of course, below the method of my class

    getBms: function() {                    console.log("getBms start",this.tags);
        let BxB = this;
        //Bookmarks search for tags and sort by
        search(      [{ tags: this.tags }],  sort[this.order]        )
            .on("end", function(results) {
               
                results.forEach(function(bm){        //console.log("Search ended for " + BxB.id)
                    BxB.addmenuitem(bm.id, bm.title, bm.url, getFavicon(bm.url));    
                });
                view.setIcon(BxB.id, window, {
                      "16": "./tag16.png",
                      "32": "./tag32.png",
                      "48": "./tag48.png"
                    });                                    console.log("getBms SEARCH end");
            });
    },
