PhobiaBlocker FAB V מאת

You're on your favorite chat or browsing social media when suddenly a wild and scary image of a spider appears! PhobiaBlocker lets you enjoy a phobia free web.

PhobiaBlocker blocks images related to your phobia. Choose what to block from a large list of real-world objects (e.g., insects, animals, plants).

Features
• Automatically block images representing real-world objects you have chosen
• Manually block or unblock images using the right-click menu
• Block all images across all websites
• Automatically block or trust (to improve performance) images whose src matches a specified regex (blocking takes priority)
• Add trusted websites (domain name with subdomain) to improve performance

Options
• Quick option to block spider-like and insect-like images
• Advanced selection from a long list of real-world objects
• Speed/Accuracy tradeoff of the automatic blocker
• Risk management of the automatic blocker
• Add or remove regex rules to automatically trust or block images using their src
• Pause the automatic blocker (manual blocking remains enabled)
• Enable dark or light mode (dark mode is enabled by default)
• Label trusted websites from the popup menu

Privacy
• No browsing data is sent to an external endpoint
• Images are analysed on your computer but they are not saved, except in a transformed form within a local cache that can be disabled in the options

Technical details and restrictions
• Machine learning models for ImageNet classification are used to analyse images. The list of things to block comes from ImageNet classes. This is why only real-world objects are supported. For instance blocking abstract phobias like heights or gore is not supported.
• The extension analyses <img> and SVG <image> elements. When a new image is added to the DOM or changes, the element is analysed as well. Images from <canvas> elements and the CSS background-image property are not supported.
• Images are temporarily blocked before they are analysed. Images can blink before being temporarily blocked in rare cases.
• Most of the extension's size is due to the machine learning models and the library to execute them.
• The automatic blocker uses a cache of decisions, which can be stored locally or used only temporarily. The cache contains non-cryptographic hashes of images. Both the cache and its persistence mechanism can be disabled in the options.
