Inspired by this MSO question.

This tiny userscript will add a link to the timeline for any post, just below the "favorite question" star button.

Example image:

This is the code:

    var newuri = "";
    if(post && post.length > 1){
        newuri = location.protocol + "//" + location.host + "/posts/" + post[1] + "/timeline";
    }
    $(".favoritecount").after("<a href='" + newuri + "'>View Timeline</a>");
}

Feel free to submit any bugs, feature requests and comments on the script.

This script was tested with the following settings:

  • Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:20.0) Gecko/20130520 Firefox/20.0 PaleMoon/20.1-x64
  • SO and MSO pages, other SE pages will probably work (please tell me if they don't!)
  • Greasemonkey 1.9

Good idea. There's a few minor niggles, though:

  1. Don't use unsafeWindow, this will break in Chrome and will not even work in Firefox+Greasemonkey if the effective @grant changes.

  2. Avoid leading * wildcards in @includes, if you can help it. This is a big performance hit. @match limits the wildcard scope and performs much better and reports the sites/security correctly on Chrome. This gets all current SE sites:

    // @match       *://*.askubuntu.com/questions/*
    // @match       *://*.onstartups.com/questions/*
    // @match       *://*.serverfault.com/questions/*
    // @match       *://*.stackapps.com/questions/*
    // @match       *://*.stackexchange.com/questions/*
    // @match       *://*.stackoverflow.com/questions/*
    // @match       *://*.superuser.com/questions/*
    
  3. The regex match needs to be more robust, to account for all legal characters in the URL, and for anchors.

  4. Use injection so that the script will work on most userscript-capable browsers (Chrome, Firefox, Opera, Safari, etc.).


Here's a variant of the script I've been using. It also adds a "revisions" link since a post's history is sometimes hidden. It works on Chrome and Firefox, and should work on most other userscript-capable browsers:
