Thank you!

Note we provide updated Debian packages: https://support.mozilla.org/en-US/kb/install-firefox-linux#w...

You also get the ability to deploy all browser infrastructure on-premise, to effectively decouple yourselves from us and get sync data, telemetry, and so on all stored on-prem, serve updates from your own servers, etc. This is something that wasn't really practical before.

I'm not sure why we would be okay with breaking a browser's trust in that way

I'm not sure what you mean here. If we accept that this is something a lot of Enterprise deployments require, wouldn't you prefer to have things like DLP, VPN and security logging be built-in in the browser, rather than being provided by third-party products that intercept or hook the browser traffic somehow?

If the site is public and the issue happens in a fresh profile, just a link here would likely do the trick.

Not sure if you're aware, but this button does actually exist in the help menu, at least for getting a public report filed. I looked through our tracker and didn't find any report similar to yours though (..and Office365 has a ton of webcompat bugs on file...), so I'd recommend you and "others" to actually file those bugs.

Finding and fixing those bugs in websites (unless they're behind a login that you can't easily sign up for) typically isn't the issue, but getting ahold of the site owner sometimes is.

If we can't get ahold of the website operator, or they're slow or unwilling to fix it, we can ship compatibility shims in the browser.

Take a look at about:compat to get some idea.

Browser engines are incredibly complicated, yet at the same time are very performance and security sensitive while needing insane backwards compatibility and full multi-platform support. That unfortunately requires large teams, which is why there's only Gecko and WebKit/Blink left.

"Making a browser" you can do with a team of 1 person. Just search & replace the branding in the Chromium source.

I think we hit all the features you mention but not sure about the above.

(Regardless of one's feelings about generative AI, I think some features like local translation or alt text are too nice to be labeled "LLM shit", but I admit I am biased)

Warning (instead of blocking) is possible. Due to the security logging (plus, if wanted, SIEM integration) you get the flagging.

Can you run data through a local or corporately-situated LLM instructed to "Assess whether this looks potentially sensitive" via a given set of rules, and flag it to the user or a supervisor to proceed/abort?

Not in the first version, but this is an area we are working in.

what kind of hooks and feedback/UI interaction is available for third party integrations?

We support the standard SDK for this which is also used by Chromium based products:

That's how Trellix and Broadcom integrate with it as well.
