on every email it says that it blocked tracking but that the source was unknown. all its done so far is block pictures in emails from restraints and my work emails.
Does not work. Tested with Acymailing and it was able to track my email back without any notice from the extension.
Приложение не работает, автор не выходит на связь. Возможно, что оно скомпрометировано.
Just doesn't work unfortunately
I'm not a techie, so I don't really know how to determine of it prevents the tracking like advertised. But if I assume it does, then I still have to turn it off because it breaks images in emails I receive from trusted sources.
No longer works for the last couple of weeks. It shows the red eye, that trackers exist but still load them and notify the sender. I know because I sometimes add trackers myself and since the last few weeks it started showing me open notifications for my own emails when I open them, something that didn't use to happen before.
5 stars for working all this while.... BUT IT HAS STOPPED WORKING TODAY. I use Streak to track outgoing email and Pixelblock to block tracking on incoming .... Till today, whenever I opened an email Sent by me (hence tracked by Streak), a "seen" would not get registered because PixelBlock would block Streak's tracking attempt. This is no longer working. Streak registers a "seen" when I see my own sent email (purportedly protected by pixelblock). Ergo, pixelblock has stopped functioning. Please fix.
Using this extension for many years, works great. However, I have few questions/suggestions: 1) In the new Gmail eye icon is not shown, however, pixel trackers are still blocked. Will be nice to have the eye icon back. 2) Why does this extension requires access to all website? I limited it to https://mail.google.com/* and it still works.
They break all of my ad images when using Google Ads. I have to disable it from Chrome to manage my paid search campaigns.
Hi PixelBlock Team, This has reference to the receiving of mail from one of my known person and it seems to be a tracking one. The mail included a button texted as "click here to open few message" and clicking on the same resulted into opening of various links. It totally seems to some kinda malware/ hidden app to track my account and phone. Found no help from PixelBlock on this. Please do suggest in order to be clear on this. Thanks Shubham Sharma
