- Rated 5 out of 5by Firefox user 12596004, 7 years agoVery configurable and useful tool if you don't want to be easily fingerprinted. In 1000 years it will be common knowledge to install in every Firefox. For now, we're the lucky ones that learned about it.
- Rated 5 out of 5by Firefox user 12636919, 7 years agoSeems to cause issues with direct links to images. When this addon is activated only a white page is displayed instead when the domain is loaded for the first time. Deactivating the addon and reloading the link makes the image show up correctly. Afterwards the addon can be re-enabled again without making the image disappear again (only lasts for the session, restarting firefox breaks it again).
FF ESR 52.5.0
Edit:
The issue has been resolved, the author created a separate version. Great support!Developer response
posted 7 years agoThis issue was already reported to me. But I'm not able to reproduce it on my end. Please create a new issue on github with the informations to reproduce the problem (Firefox version, installed Addons, CB settings, URL to the not working image and if the problem is still present when a fresh profile is used): https://github.com/kkapsner/CanvasBlocker/issues/new - Rated 5 out of 5by areafix, 7 years ago

- Rated 5 out of 5by Firefox user 12806971, 7 years agoNew features are somewhat confusing for usual users like me. Should I enable transparency blocking?! ot it doesn't matter much?!
Also when updated some options are missing like the "Ignore the most frequent colors".
Also why not to set Random Number to Persistent by default, it will be changed on every browser startup, right?!Developer response
posted 7 years agoThe former versions faked the transparency always. But since this channel is treated differently by the browsers I think it is saver to not fake it. It does not affect the security.
Regarding the missing options: only these options are displayed that are useful with the other selected options. The mentioned "ignore the most frequent colors" is only displayed in expert mode and when faking the read API.
For the default random number generator I ask you to open an issue at github. This has to be discussed in more depth. I myself are not sure what the default should be.
