Call javascript from address bar

Question

Opera

Hello.

There is the following task. You need to give the user the ability to call the script at any time on any site.

The solution was this: the user adds a link with the script I need (href = "javscript: ...") to favorites and clicking on it does what is needed.

The problem is that FF is older than 7 and Opera Next (not tested everywhere) does not react in any way to javascript input through the address bar.

What other options are there? Now the only thing on my mind is to write extensions for these browsers. But I want to find some simpler solution.

Thank you.

Answer 1

It's called bookmarklets. It seems there were even articles on how to do it right.

Answer 2

Load a small page on which the script will be, no?

Answer 3

Maybe userscripts? True, for IE I have not seen such a plugin.
