uBlobeBM

Welcome to uBlobeBM (BlobeBM uBlock Edition)!

uBlobeBM is a tool that can run bookmarklets using uBlock Origin by utilizing the uBlock Run exploit. It’s very useful if bookmarklets don’t work on your device or are blocked by your administrator. uBlobeBM also does some CSP bypassing shenanigans, which allow it to work in a lot of sites (like Blooket) in which regular uBlock Run or uRun don’t.

How to Setup uBlobeBM

  1. Installing uBlock Origin
    Make sure you have uBlock Origin installed on your computer. If you don’t, download it here.

  2. Modifying Advanced Settings
    • Go to:
      chrome-extension://cjpalhdlnbpafiamejdnhcphjbkeiagm/advanced-settings.html
    • Find userResourcesLocation.
    • Change it from unset to:
      https://raw.githubusercontent.com/Blobby-Boi/uBlobeBM/refs/heads/main/blob.js
  3. Modifying Custom Filters
    • Go to:
      chrome-extension://cjpalhdlnbpafiamejdnhcphjbkeiagm/1p-filters.html
    • Add the following line of code: 
      *##+js(blob.js)

How to use uBlobeBM

  1. Opening uBlobeBM
    • Press CTRL + Shift + ~ to open uBlobeBM.
    • If you are warned that the website you are running it on has a strong Content Security Policy, it means that some bookmarklets will not work as expected. Those are mainly the ones that create a script referencing an external source.
  2. Adding Bookmarklets
    • Locate the “Enter bookmarklet code here” text input.
    • You can either:
      • Copy and paste the bookmarklet code.
      • Drag the bookmarklet from your bookmark bar into the input field directly.
    • Click the green “Add Bookmarklet” button.
    • Enter the name you’d like for the bookmarklet. The name can be anything, and it can be changed later.
    • You can add as many bookmarklets as you need into uBlobeBM, and they will save even if you close the window or shut down your device.
  3. Executing Bookmarklets
    • Once added, your bookmarklet will appear which consists of four buttons:
      • Blue button: Run the bookmarklet.
      • Red button: Remove the bookmarklet.
      • Yellow buttons: Edit the bookmarklet’s name and code.

    You might come across a website where uBlobeBM complety fails to load on (such as Github or any Google Subdomain). This occurs because they have a strong Content Security Policy that can’t be bypassed easily, though there are very few of them.

    I hope this helps! :)
