// Version      : 2023.03.17

// License (MIT): https://raw.githubusercontent.com/icpantsparti2/browser-bits/main/LICENSE
// Disclaimer   : Use with care at your own risk
//
// This is only useful when you have a large amount of add-ons and need to
// change the order shown under the "Extensions" (jigsaw piece) button.
// For Firefox v109 onwards (until the UI has a better way to sort them,
//   beyond the right click pin/unpin which places them at the top).
//
// To run:
//   (1) open the 'about:addons' page (Ctrl+Shift+A)
//   (2) open the Web Console (Ctrl+Shift+K or F12)
//   (3) copy/paste the code into the Firefox web console and run
//
// There are three options:
//   option 1 (SIMPLE)   add-on alphabetical order (1 step)
//   option 2 (OLD)      with optional manual add-on sort (3 step)
//   option 3 (NEW)      with drag and drop interface
// option 3 will run if you copy and paste this whole file into the console
// (the code for options 1 and 2 is within comments)




// **** option 1 (SIMPLE) **** add-on alphabetical order (1 step)
// What happens:
//     - paste the code into the web console and run
//     = this changes the about:config pref "browser.uiCustomization.state"
//     - the old and new values are output to the console (if you need to
//       keep them: right click, and copy object, paste/save in a text editor)
//     note: pinned add-ons might not move (unless you right click unpin them)
//     - close and re-open Firefox to see the changes
// (if required, code can be saved in a bookmark URL, and dragged to console)
//

javascript:AddonManager.getAddonsByTypes(["extension"]).then(addons=>{var order=[];addons.sort((a,b)=>{return a.name.localeCompare(b.name);}).forEach(addon=>{if(!(addon.isBuiltin||addon.isSystem)){order.push(`"${addon.id.toLowerCase().replace(/[{}@.]/g,"_")}-browser-action"`);}});var oVal=Services.prefs.getStringPref("browser.uiCustomization.state");var nVal=oVal.replace(/(^.*,"unified-extensions-area":\[)[^\]]*(\],.*$)/,"$1"+order.join(",")+"$2");Services.prefs.setStringPref("browser.uiCustomization.state",nVal);console.log(`// old\n// Services.prefs.setStringPref("browser.uiCustomization.state", "${oVal.replace(/(["\\])/g,'\\$1')}");\n\n// new\nServices.prefs.setStringPref("browser.uiCustomization.state", "${nVal.replace(/(["\\])/g,'\\$1')}");\n`);console.log(`// about:config pref "browser.uiCustomization.state" changed, old/new values are shown above, ** please restart Firefox to apply **`);});

// **** option 2 (OLD) **** with optional manual add-on sort (3 step)
// This generates a list with more code, which then generates further code for
// setting: Services.prefs.setStringPref("browser.uiCustomization.state"...
// What happens:
//   - We do this in three main steps, you have control and are given the
//     old setting value.  The change is only applied when you run step 3.
//     (step 1) - paste the code into the web console and run
//              = this outputs to the console a list of addons/ids with
//                some further JavaScript code
//              - copy the console output (right click, and copy object)
//     (step 2) - keep as alphabetical order (and continue)
//                  - or paste the code into a text editor and change the order
//                    of the add-on name/id lines, then copy back to clipboard
//              - paste the code into the web console and run
//              = this outputs to the console the old (current) and a new
//                value for user preference "browser.uiCustomization.state"
//              - copy the console output (right click, and copy object)
//     note: pinned add-ons might not move (unless you right click unpin them)
//     (step 3) - (you can paste the code into a text editor to check it)
//              - paste the code into the web console and run
//              = this changes the value of "browser.uiCustomization.state"
//              - close and re-open Firefox to see the changes
//     (step 3 variation)
//              - you could alter "Services.prefs.setStringPref" to
//                "user_pref" and add that to a "user.js" file in your Firefox
//                profile folder, restart Firefox for the change to apply
//                then remove the line which you added to the "user.js"
//
/* step 1 - run to output code listing add-ons and ids */
