Firefox extension to block image requests (default), blur loaded images, or load images normally. Pick a mode from the toolbar popup.
Block — image requests are cancelled; placeholders and text stay readable.
Blur — images load but are blurred heavily; text stays sharp.
Per Mozilla’s temporary installation docs:
- Open Firefox and go to
about:debugging. - Click This Firefox.
- Click Load Temporary Add-on….
- Choose a packaged
.xpi(see below) or a file inside the extension folder.
To build a valid .xpi (manifest must be at the root of the zip), from this directory run:
./build-xpi.shThen load deepblur.xpi from the file picker.
