Subject: OCSP Must-Staple Behavior Observations in Firefox (Including iOS Platform)

Dear Firefox Team,

We have been conducting tests involving certificates with the OCSP Must-Staple extension and would like to share several observations regarding Firefox’s behavior across different platforms:

General Compliance with Must-Staple: On most platforms, Firefox correctly enforces the Must-Staple extension. That is, if a certificate includes the Must-Staple flag and the web server fails to provide a stapled OCSP response, the connection is appropriately terminated.

Unexpected Behavior on iOS: However, we have observed that Firefox on iOS does not appear to enforce this requirement consistently. Even when the server does not provide a stapled OCSP response, the browser still establishes the TLS connection. We are unsure whether this is due to platform limitations or an implementation inconsistency.

Redundant OCSP Requests Despite Stapling: Additionally, we found that Firefox still initiates an OCSP request even when a valid stapled response has already been provided by the server. This behavior not only degrades performance but may also introduce privacy concerns, it contrary to the original privacy and efficiency goals of OCSP Stapling.

Hello, When I try to use Mozilla firefox, using this rather than Google chrome I get the following warning from Malwarebyte: Exploit.PayloadProcess.Block, making me feel uneasy. Best wishes, Torbjørn Borgen Lindhardt, Denmark

I've noticed over time Mozilla has become less focused on consumer privacy and more focused corporate interests.

My questions are to you developers of Mozilla.

Would you have reached success in the past using this model?

I've noticed a corporate trend of brands being consumer friendly in the beginning of their history then over time snubbing the customers in favor of getting paid to sell data to corporate interests, data brokers and government entities.

Should we trust you?

I've been using Firefox for almost 20 years and anyone can agree that this browser isn't getting better over time.

Can you provide a list of all the third parties you deal with selling our data?

I have a nagging feeling this isn't the browser it used to be and some of us will need to change to a less corporate focused browser to protect our data, since it seems you aren't interested in that model anymore.

Why in the world am I seeing these tab Groups and Studies

After reading some posts on here I went to about:config and browser.tabs.groups.enabled was set to True. I changed it to false. I never set it to True and haven’t a clue to what Tab Groups are and don’t see any reason for me to have them. I only use about 4 tabs and have no use for any more. But I was noticing a Blue square box next to a tab and clicked on it and it said I had a Tab group which I deleted. Don’t know how a tab group was built, I sure didn’t ask for one and haven’t a clue what they are???

While researching this I seen something that about:studies could be the problem. I looked at it and it showed I was or had been in 4 studies!! All of the studies showed completed. I did not join or ask to be in any studies, what is Firefox doing signing me up for studies? I went to Privacy and Security and nothing under Firefox Data Collection and Use is checked including install and run studies. I have people’s secured data on here and if it gets out I could be sued!

I have run 3 full scans of different virus and all is clear. This must be something Firefox is doing without asking me for permission. I did find that browser.tab.groups.enabled was true, so I know FF must have done that during an update and I set it to False. Some post say FF will change it back to True?

What is really strange is the studies, it says they did 4 that are completed, yet it was not checked in the Privacy and Security section. Can't tell when as there is not a date.

These were the studies:
