How to cancel Boomark navigation with JS in Firefox?

Question

JavaScript

Nakalyakal script, namely - the numbering of positions in the issuance of a search engine.
In chrome, the created bookmark works well when it is called, the page does not refresh, but in the fox it does not want to.
That is, formally it works there, but upon completion of the script, it goes to the "address", i.e. to the JS code itself, and I see on the new page:
[object Object]
And how can I make the fox just work out this bookmark and not refresh anywhere, in the manner of a regular console in the inspector?
