[i]Thank you very much,

This autoupdated today.
After the update I can no longer login to any of my Wordpress sites.
An error occurs:
The page you are trying to access is restricted due to a security rule.
I’m going to try and attach a screenshot.
This does not happen in IceDragon, Chrome. Firefox etc.
What happened?! Please fix it!

Edit: Is it possible for me to downgrade the version and if so where can I get it (I can’t find any)?

Hi Cyberdave, thank you for the feedback.

Can you provide us with a few links to your sites please?

[i]Thank you very much,

After investigation, we believe the problem is the HTTP Referer header tracking blocking.

Steps to fix:

  1. Go to Settings and click Advanced.
  2. Locate and turn off this: “Do not allow websites to know where you came from (suppress HTTP Referrer header)”. This setting is off by default.
  3. Try logging into Twitter/Wordpress again.

The team fixed a small defect with this option and it now works well, clearly too well for some sites.

We suspect there is some authentication on the server side for this header when logging in.

Let us know the results,


That worked! I had it on so I turned it off and then was able to log into both of those sites!
Thank you for figuring it out!

Video playback problem on Intel HD Graphics 4000 still hasn’t been fixed. I know adding --disable-accelerated-video-decode to command line helps, but other browsers don’t need that switch to work correctly.
Besides, it’s 2018… Command line? --disable-accelerated-video-decode? --high-dpi-support=1? --force-device-scale-factor=1? Isn’t it possible to add some switches to the graphical interface?

I was using the extension on the link(

It is running at CD v66.0.3359.117 64-bit(ScreenShot1), but it is not running at CD v67.0.3396.99 64-bit(ScreenShot2)

I just updated but the icon on the taskbar still blank.

I, too, couldn’t install an extension in v.67.xxxxx. I don’t now if this can help you:

In ‘General Task’ ‘Unblock Applications’ I unblocked some comodo’s applications, then I chose another configuration which I configured myself with less restrictions and I could install the extension. Otherwise you could try to install a new profile.

Always crashes on Facebook.
Why version 63 still works fine, but all newer versions has multiple problems?

Hi thelondoner, thank you for the feedback!

We will look into the issue, but we need a few more details: what operating system are you running CD in? What video card do you have?

Can you run the browser with the --disable-accelerated-video-decode parameter and see if Facebook still crashes. This will be included in the future as a option to enable/disable.

[i]Thank you very much,

The Dragon X32 and X64 crashes with hardware acceleration, or without.
CD X32 crashed more then X64.

Win 7 x64 Intel Grafics(Original Intel Drivers, not from windows update).

I’m not sure, if the video on Facebook is the crash reason, cause in my case automatic video playback is disabled.
Sometimes it crashes when you just scroll the timeline fast. Mostly, if I want to see the pictures inside the post, or if I want to check a someone’s profile.
Sometimes you just read the post, but facebook add line changes the content…and bumm )))


Try to visit this site…I can not.

No problem at all from here. :-TU

I don’t see a setting for hardware acceleration anymore.

To disable hardware acceleration on older GPU’s we suggest the follow.

  1. Copy the Comodo Dragon launcher Icon on the desktop.
  2. Rename the cop to “Comodo Dragon, disabled hw acceleration” or similar so you can identify it.
  3. Right click and select properties.
  4. Under Target add the --disable-accelerated-video-decode to the command. For example: “C:\Program Files\Comodo\Dragon\dragon.exe” --disable-accelerated-video-decode.
  5. Click Ok to save the changes.
  6. Launch Dragon with the new launcher.

Alternatively, you can try the v68 beta which has some video improvements and may solve your issues.

Hope this helps.
