I am looking for a web browser I can use to manage my company on and I don't know much technology or cyber security and I am anticipating opening my card and collectibles shop within a few months and it took alot to get this far so I don't want to make any decisions that will create any kind of complications with my business. I am looking for one secure browser to use exclusively for my company I already told you it is a card and collectible shop but I will sell online hopefully. So my question is is there anything that I should know about vulnerabilities that could potentially be used to exploit my business

I am using version 143 for Linux and it is suppose to have improved fingerprinting protection. But when I go to https://coveryourtracks.eff.org i still see a result that says "your browser has a unique fingerprint"

Is there a parameter I should be enabling ?

Lately, I have been noticing that new Firefox browser windows (not a new tab, a new window) have been opening seemingly randomly on me. The sites in these new browser windows are always commercial in nature and seemingly random in subject matter. I am not aware of having clicked on anything that would cause the new browser windows to open. I need to know how to block this from happening; I am unable to figure it out in the various Firefox Settings.

my favorite browser firefox isnt enough help to keep my privacy secure (Its 100% confirmed)

I just learnt that my internet provider is blocking some domain like web.telegram.org which is very annoying. The solution i found on internet is vpn or tor browser.

Am i expecting something from firefox that it cant help me with?

A free vpn or tor browser like functionality?

I am so sorry to go away from it but look like if there is no way firefox can help me secure my privacy then i will have to.

Please try to be friend and help like a friend

Dear Mozilla Support Team, I am writing to report a significant security breach involving my Firefox browser that resulted in session hijacking my Firefox devloper browser email was ( [email removed]@gmail.com ) in panic log out form my account and reset the laptop now I don't have access to the data and the compromise of multiple high-value accounts (Discord, Rockstar, and Telegram). Incident Details: Date of Incident: February 2026 Primary Exploit Identified: BeEF (Browser Exploitation Framework) OS: Windows 11 Symptoms: allowing an unauthorized party identified as operating from an IP in Vietnam to bypass 2FA by stealing active session tokens. Despite having security measures in place, the attacker successfully: Accessed my saved Google passwords. Reset my Rockstar Games and Discord account passwords. Gained access to my Telegram account (which has since been deleted). Technical Observations: Standard scans with Windows Defender and Malwarebytes did not immediately detect the "infostealer" responsible, suggesting the use of "Living-off-the-Land" (LotL) scripts or a sophisticated browser-based hook that persisted even after clearing basic cache. I am reporting this to help Mozilla investigate how Firefox's cookie storage and session management can be further hardened against BeEF-style hooks and unauthorized token extraction.

Have tried different solutions like Malware product and cleaning cashe and cookies. When I search a known safe site I get redirect by Convertitmas stating the (known safe) site is unsafe. Best regards Henrik Nygaard

Long story short, I want to view a link from a QR code, but I don't want to open it in Firefox itself. I fear that doing so would expose me to scams. So, I want the link prompt (deny or allow) to allow me to copy the url, so that I can paste it in a different browser.

Since several days every time I visit a webpage I see that there is a popunder from syscsrv.com!

What can I do to stop this?

Regards

Hi,

Since last week I am unable to properly use some websites that are failing due to CORS requests, but they were working before. Some examples are es.webuy.com or a local Jellyfin instance. After trying to enable/disable some settings that I thought could be related to the problem, like security levels, I ended up creating a new profile. In this new profile everything works, but as soon as I synchronize my Mozilla account, then these websites start failing again with CORS requests errors.

Any idea about what setting might it be the one causing problems? Or any idea about how can I debug/troubleshoot it myself?

Thanks!

Is firefox safe? How is it's privacy compared to chrome and edge? Is firefox at par with chrome and edge? In terms of popularity compared to chrome and edge -- how does firefox stand?

WHAT THE HELL IS THIS???
