Description

HTML Content Blocker provides a user-friendly interface to quickly block various HTML contents (Script, Style, Image, Object, and Media) on any webpage. To work with this addon, please open the toolbar popup and press the desired content button (at the top) to block, then reload the tab. This extension has two modes to operate. The first and default mode is Global. In this mode, the addon is active for all domains except those listed in the allow-list table. The other mode is per-domain, where the addon is active only for the domains in the block-list table. To switch modes, please press the toggle button at the bottom-left corner of the interface. To add domains to the allowlist or blocklist table, please navigate to a website, then press the plus (+) button at the bottom footer. Likewise, to remove the domain from the table, press the minus (-) button. Badge icon text shows the number of blocked items for the active tab. Note: The toolbar popup interface supports dark mode. To switch the interface theme to dark, please press the moon icon on the bottom toolbar. To report bugs, please visit the addon's homepage and fill out the bug report form (https://mybrowseraddon.com/html-content-blocker.html).

You can't block html elements. Useless. Uninstalled.

It was great for awhile but now videos play even though media blocker is checked.

Does not work as advertised. It's not blocking anything and the documentation says there are no settings to configure.

Like the other two, doesn't work in chrome. STILL plays blasting videos and audio on weather pages. Yanking this worthless extension.

Did not block huffingtonpost autoplay ! "HTML Content Blocker" did. Find and install it.

Didn't work for me. Also it's absurd how things are layed out. How do you know if you've activated a particular block? For example, I want to block "java" (doesn't work btw) but I have no idea if it's active or not. Ditto with the other options like blocking "media", "image", "object" and more. Sure you have a number being posted but that doesn't mean much especially if nothing is being blocked. I verified with other applications and manually disabled java script via Chrome browser to verify what happens when I block "this or that". This app is a fail.

While it does block videos from auto loading, there is no option to right click on a video to allow just that video to play. I'm not going to keep turning this on and off. Removing this extension.

It appears no longer supported. It used to be very effective. Now video on the Weather Channel can't be stopped unless you use an adblocker. The default settings are on and it grossly interferes with virtually every site. Instead, the default should be to allow sites and blacklist them instead of whitelisting each site (non intuitive logic).

This extension is great and works flawlessly and as expected! I just wish it supported a blacklist mode instead of the whitelist one, with each rule or entry in the blacklist customizable in terms of what to be blocked on that webpage... That would've been more convenient imo, but nonetheless, it does the job! Update: It keeps failing to work every now and then, and I believe its developer updates it to make it work again afterwards or something.. But it just is not reliable 24/7, unfortunately. A waste of great potential. :(

The JavaScript Block is great for annoying news sites. Sadly, Sites can be Whitelisted but not Blacklisted, making it cumbersome to use. Turning on, activates for the entire browser, not just the current tab. Would prefer Blacklisting Sites.

Does a good jobs and speeds up pages with annoying Ad- and media content (in some cases it renders those pages from being ususuable at all) BUT you have to alter settings manually for each page. This addon would be much more useful if it remembers the settings for each page or whole domains.
