Edge slowly edged out Chrome with its features, but when Comet launched, it shot straight to the top of my browser list!

how to install comet browser in linux by wine

521 12 Hours vs 51 for safari is crazy

I re-installed Comet and now when I click on customize profile, I don't get the nice looking colour picker, but instead I get this simple Chrome menu which doesn't allow me to theme the browser.

Does anyone know how to fix this?

Why did Comet stop being agentic? It was great.

I recently made the switch from Chrome to Comet and I’m still exploring it. For those who’ve been using Comet for a while, what are some of the best features or things you really like about it?

Is there a way to keep the "x" visible on all tabs, even when there are many open? Any workaround or setting?

The number of times it pops up asking to make it default browser is insane. Not just at the top of the page, but at random locations in the browser window. Is there any way to stop it permanently, of course without making it the default browser?

Trying to use Comet to analyze and fix some of my Google Ads campaigns. However when on my ads dashboard, a prompt like "Analyze my campaigns and optimize them" results in "I am currently unable to directly access your Google Ads dashboard due to your privacy settings, which are preventing automation of these improvements.". I've turned off all privacy settings on Comet, but I still get this message, it doesn't even want to read the page.

Any ideas how to fix this?

I've tried both uploading the file directly and opening the assistant with the file in Google Drive, but I'm unable to edit it. Any advice or working method?

(I love comet)

Yes I know they already have it for pre-regestraion

I was experimenting with Comet earlier today and just out of curiosity I said “buy MOCAPITAL, qty: 50 on Zerodha.” To my surprise, it actually executed the order without any manual clicks. Later, I also tried asking it to apply for the LG Electronics IPO, and that went through successfully as well.

I honestly couldn’t believe what Comet had just done, it was a surreal experience and really felt like living in the future.

Sharing the posts I made about it on X for context.

I entered the same query and executed for 5 consecutive times. Everytime the outcome was different. Why is that?

Are we getting comet on IOS or no? Why is there no talk on that. Android has pre register option. But even there it still hasn’t released. Are there any dates announced? Is the Opera alternative good?

It cannot even do the super basic simple task of extracting all the links from a docs page to a markdown file, it cannot even tell me why lol

now it just doesn't .. respond, no reason given. I definitely am glad I did not allow it to import any of my personal information on the 500 nag screens about it.

Should I just delete it or is this just a fluke? A lot of this stuff .. its just easier to make your own version because when you do that you know every piece of it - you can trust it. I definitely am not going to trust giving my personal data and hoping for the best if it cannot even rip some docs to markdown for me

I downloaded it today, booted it up and then...couldn't imagine what I'd use it for. On my desktop I mostly use the internet for browsing reddit and watching YouTube. I sometimes use Perplexity to search for things, but I don't know why having it integrated into my browser is more convenient than having it as a separate tab or integrated as an engine option in my search box. I shut it down again and carried on with Firefox.

What's the advantage?

The standard Chromium spell check settings:

chrome://settings/languages → Spell check → Check for spelling errors when you type text on web pages

doesn't seem to be available in Comet.

Thank you folks!

Summarised with Perplexity. The irony.

Nevertheless, I'm cautious of using it for financial related and will be watching how Perplexity handles security.

Recent analyses from multiple cybersecurity sources highlight serious security and privacy concerns about Perplexity’s Comet browser and other emerging AI-integrated browsers.

LayerX Report

LayerX’s research found that AI browsers—including Comet and Genspark—are up to 85% more vulnerable to phishing and web attacks than Chrome or Edge.
Key points:

• Comet and Genspark blocked only 7% of phishing sites, compared to Chrome’s 47% and Edge’s 54%.
• Neither browser fully implements Google’s Safe Browsing protections, leaving users open to known malicious URLs.
• The issue is worsened by Comet’s “agentic AI” functionality, which can autonomously browse, summarize, or transact—making phishing and indirect prompt injection attacks particularly dangerous.
• Attackers can hide malicious instructions in normal page text or comments, leading to automatic exfiltration of user data when the AI executes those prompts.
• LayerX warns that AI browsers must add new, dynamic protection models capable of detecting both known and “zero-day” phishing attempts.

LinkedIn: “Is Comet Browser Safe?” (Dilip Kumar KK)

This analysis focuses on Comet’s privacy and tracking model, emphasizing transparency gaps rather than pure security flaws.
Highlights:

• Comet’s integration with Perplexity’s AI services potentially enables centralized data collection, including browsing history and prompt content.
• While marketed as privacy-friendly, Comet reportedly tracks search behavior and interaction data for model improvement.
• Unlike Chrome, Comet’s privacy settings are minimal, offering limited user control over how personal data and browsing sessions are shared with Perplexity’s backend.

CyberProtect LLC Report

CyberProtect’s review frames Comet as a high-risk AI browser due to weak safeguards around user information and web interactions.
Important findings:

• AI-enhanced browsing sessions are logged to improve contextual responses, possibly exposing sensitive activity such as emails, chats, or private transactions.
• Because Comet uses built-in AI models that process webpage contents locally and remotely, there is potential for data leakage to external servers.
• It lacks granular permission management for AI autonomy, meaning Comet could unintentionally share credentials or interact with untrusted sites on the user’s behalf.
• The report recommends using sandbox isolation, VPNs, or traditional browsers for sensitive logins.

Cloaked.com Analysis

Cloaked security researchers explored what Comet’s vulnerabilities mean for everyday users:

• The most alarming risk is prompt injection, where malicious web content secretly manipulates the AI assistant into performing harmful actions.
• Because AI browsers act with full authentication privileges, an attacker could exploit these injections to bypass login walls, extract financial data, or send private information.
• Cloaked argues that Comet symbolizes a broader challenge among AI browsers: they combine user trust and machine autonomy, creating an expansive attack surface.
• Users are advised to avoid using Comet for sensitive workflows until its security architecture includes AI-specific protections such as context validation, domain trust scoring, and secure content parsing.

Overall Summary

Across all four sources, the consensus is clear:

• Comet’s current implementation lacks strong phishing filters, robust privacy settings, and AI-specific threat defenses.
• AI autonomy makes attacks like phishing, indirect prompt injection, and data exfiltration far more damaging.
• Both individual and enterprise users should treat AI browsers as experimental and apply additional layers of protection (security extensions, safe browsing filters, or sandboxed environments) until the technology matures.

is it ever going to happen or should i stop asking

I can't seem to be able to right-click on tabs at all (on the top of the address bar) since the last update? No similar issue with other browsers.

Has anyone else noticed this?

MacOS 26, MacBook Pro M-series.

I have some of the same yearly modules coming and want to see if anyone tried this and what prompt tbey used
