The breakage is caused by ETP protection that we block the cookie access of www.linkedin.com because LinkedIn is a tracker and social tracker. Firefox will throw a security error when a third-party context tries to access storage/cookies and the LinkedIn script doesn't handle this exception. Therefore, the page failed to load.

I don't know if we can do anything from the platform standpoint to resolve the breakage. Maybe there is something we can do from the webcompat standpoint. Tom, any thoughts?

I also found a protection panel UI issue here that the protection panel shows that www.linkedin.com is blocked due to the social tracking protection. But, actually, we don't enable social tracking blocking in standard mode.

Since that page only really presents the LinkedIn iframe, we could use SmartBlock to detect this case (an attempt to load the linked-in frame from this URL) and just change the window location to the iframe's URL. That shouldn't require too much effort, and it seems to work to visit the iframe's URL directly.
