Multumesc Echipei COMODO !

Updates to this 64 bit w/o any problem . . . . running well

Win10 Pro x 64 1803 (17134.48)

Installed with no issue both as stand alone and upgrade. Just note that it’s default page is no longer the yahoo Comodo one, is this normal now?


Started Up my PC and Comodo is missing

Trying to install x64 but in no success (also restarted system)
What …?

Software installed manually successfully on 64bit but in x86 program files folder

“Use hardware acceleration when available”

This option is not working anymore, as it is always on (Cannot switch it off anymore)

Still running well at this end. I’m actually glad the default load page is just chrome://newtab/ it looks like Comodo still gets yahoo search taged if you search from the top bar so it’s all good.


Can we have any chance to use our old interface in Dragon? I missed the soft squared tabs

Please answer me devs, is it possible or not? Don’t leave me un-answered.

So in current version (66.0.3359.117) video simply doesn’t play instead of crashing a tab completely (v65.0.3325.147):;msg877210#msg877210
It’s an improvement, but could we get back to normal video playback again?

Hi Eric, yes this is the new intended default setting.

We focused on delivering codebase updates. I’ll investigate this but I’m sure most users would prefer codebase updates over square tabs so this took priority in the past.

Thank you for the answer Shane :-TU I hope people can get codebase updates in time :slight_smile:


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.

Hope this helps.

Launching with --disable-accelerated-video-decode as described above may help.

Well done, Comodo! The 64bit version runs smooth on my Win10 64 bit vs.17134.81. Now if you come with regular updates this could become a real good browser.

Thank you for the feedback Momfer.


After chrome 64 showed up 4 years ago, this is some of what was written about it… Speed: 64-bit allows us to take advantage of the latest processor and compiler optimizations, a more modern instruction set, and a calling convention that allows more function parameters to be passed quickly by registers. As a result, speed is improved, especially in graphics and multimedia content, where we see an average 25% improvement in performance.P
Security: With Chrome able to take advantage of the latest OS features such asHigh Entropy ASLR on Windows 8, security is improved on 64-bit platforms as well. Those extra bits also help us better defend against exploitation techniques such as JIT spraying, and improve the effectiveness of our existing security defense features like heap partitioning.
Stability: Finally, we’ve observed a marked increase in stability for 64-bit Chrome over 32-bit Chrome. In particular, crash rates for the the renderer process (i.e. web content process) are almost half that of 32-bit Chrome
more built-in security is always good.

When will Dragon be updated to vs. 67 ?

I’m typing this post with a Comodo Dragon v67 Beta.

We’ll release a beta tomorrow.
