Mozilla rolled out a major update some time back which improved content blocking and brought other changes to the browser as well. Earlier today, we also reported that the next update of Firefox will bring the ability to mute autoplaying videos.
Now it looks like Firefox might have some more features in the pipeline for future updates. According to a new bug filing on Mozilla’s website, the browser might soon allow users to block cryptocurrency miners and fingerprinters. Mozilla has also posted a design spec showing blockers for both cryptocurrency miners and fingerprinters.
Less well known is the privacy issue due to device fingerprinting.
A device fingerprint, machine fingerprint, or browser fingerprint is information collected about a remote computing device for the purpose of identification, based on items browser reports such as your screen size, supported language and browser plugins and installed fonts. Fingerprints can be used to fully or partially identify individual users or devices even when persistent cookies (and also zombie cookies) can’t be read or stored in the browser, the client IP address is hidden, and even if one switches to another browser on the same device and can be used to compile long-term records of individuals’ browsing histories even when they’re attempting to avoid tracking, raising a major concern for internet privacy advocates. Some computer security experts consider the ease of bulk parameter extraction offered by web browsers to be a security hole.
If everything goes according to the plan, Mozilla is expected to release the update on May 14, 2019, which will bump the browser to version 67 and will add these blockers to the browser.
