Comodo dragon was a rising star in the making when comodo first introduced it. It was a time when Google was having privacy issues concerning its innovative product. However, comodo dragon has its own issues which will be discussed in the next few paragraphs.
To begin with, and apparently the most clamored for, is the updating of Dragon. Chrome and chromium are developing too fast, making major revisions to their product. (Suspicions that these supposed major changes are in fact merely minor changes have aroused. However, there is hardly any proof for this claim and until it has not been presented with enough information and sources to back it up, it shall remain as it is: a suspicion, and somewhat libelous at that.) Dragon, I believe, cannot keep up with Chrome/Chromium for the following reasons:
(1) Comodo's main products are its internet security suite and certificates (correct me if i'm wrong). Priority is and should be given to these rather than dragon.
(2) Google will develop its products surprisingly fast because of its huge workforce and resources (which include funds). It's not surprising and very much understandable if comodo cannot keep up with google who makes leaps look like normal steps.
(3) Dragon seems rather redundant with the pre-existence of similar, although not altogether the same, products which include Iron, ChromePlus, Chromium itself, Flock and others which makes Dragon look a bit unnecessary.
Updating a software in itself is a form of security maintenance. If comodo cannot keep up with the updates, it seems to be a deviation to what comodo stands for and that is end-user security. It doesn't do any good to its name and reputation. Having been left behind by two versions (as of now) is not something to be neglected. Unless otherwise proven that google had indeed been conning people (highly doubtful seeing the performance boost), Dragon ought to be kept up-to-date if it were to ever maintain its being a security-inclined product. (For the sake of argument, supposing that those major changes were indeed merely minor, changes are changes and these accumulate over time. Anything minor may become something more for specific systems. Relegating the minority to the background is fine; completely ignoring them is another matter, but that is philosophy and ethics.)
Another thing to consider about Dragon is as mentioned above, it is not the main product of Comodo to which priority should be justly given to and not to Dragon. Comodo is better off developing other products than Dragon. Considering this, Dragon would seem more like a block of stone on the back of Comodo, giving more burden than anything good with all the clamors and development needed to be done.
One more issue that Dragon seems to face are memory leaks. Dragon (installed) consumes a lot of memory in my system and has been the problem of eight other colleagues I've asked to test it with. In thirty minutes of three tabs running, Dragon can sometimes consume as much as a total of a hundred thousand and more KB worth of memory. The newest version, I've heard, leaks handles. There are possibly more, but I shall not delve onto them any further as I lack the technical know-how to write about them.
On the other hand, Dragon gives a new flavor to the browser and presents security-inclined features which should benefit security-conscious people. I will list only those that are new to dragon and not existent in any other versions of chromium. For one, a code on the verification engine of comodo has been included in Dragon, giving it access to an "advanced domain validation technology". Also, Dragon uses Comodo's installer and update mechanism whereas Chrome updates via Google Updater, which has privacy issues of its own. This updater had been removed.
Some members claim that Dragon's code has its personal edits and is a code completely different from Chrome. I have nothing much to say to this as this is not something I specialize on and such "personal edits" are hardly noticeable to the common eye. What i can say, however, is that panic and Melih have hinted on something of a grand feature or some use for Dragon that is yet to come. What it is or whether it has already been incorporated I cannot be so sure. The post is very old and I've read none so far that addresses this. However, it does seem promising and may be an innovation waiting to be released. (see http://forums.comodo.com/beta-corner-cd/comodo-dragon-alpha-ver-09016-is-now-available-for-download-t47764.0.html
Personally, i find it better perhaps to have comodo develop an extension instead, rather than the browser itself. Hence, "sharing" its security features to all other browsers and making them available to those who are unwilling to give up the things they've gotten used to (take my brother and parents for example). Plus, the possibility of it being added to CIS not only relegates itself to a position where it shall garner attention and consequently, improve at a much faster pace, but also presents an opportunity to develop its main security product and enhance Chromium which is what Dragon stands for.
Whether or not Dragon should be continued is not for me to decide. It is yours, and the staff's discretion. Judge wisely and do defend your stand. Your opinions are welcome, but do be careful in your choice of words. Your right to free press doesn't give you the right to limit others or to offend them. I discourage all forms of flaming in this post. If offense is taken, use the personal messaging feature and not this thread. Be professional.
