I use this addon to block images in Firefox https://addons.mozilla.org/en-US/firefox/addon/image-block/ . And this one to block in Chrome https://chrome.google.com/webstore/detail/block-image/pehaalcefcjfccdpbckoablngfkfgfgj . The Firefox one blocks the images and displays alt text in place of images but the chrome one does not . Is there any way to not display alt text when images are blocked?

You can use uMatrix instead. Whitelist the other types of resources for every site (such as cookies and scripts), and then control images as you want:


Point & click to forbid/allow any class of requests made by your browser. Use it to block scripts, iframes, ads, facebook, etc.
