Months and months of inconvenience from this thing. I thought oh it's a linux issue on my old machine, but got a mac and fresh install of firefox and still had issues, put it in safe mode still had issues, figured okay its got to be an extension. Disabled one by one and found out this extension was causing issues with anything Microsoft.


======
dev.azure.com gives
The page isn’t redirecting properly

An error occurred during a connection to dev.azure.com.

This problem can sometimes be caused by disabling or refusing to accept cookies.

======
Teams/Outlook/etc any links you open from there go through a nam11.safelinks.protection "safe link check" and since anything I have opens by default in Firefox then this extension would also prevent any links from opening, you would have to copy and paste.

======
Do NOT install if you use any Microsoft products unless this is updated, but at this point not worth the risk of issues with other pages
