Here’s a weird thing: as of a few days ago, bitbucket.org seems to be blocking a specific version of Firefox. Or rather, it looks to me like
a bug rather than a deliberate block, because you get a 404 error
(page not found) trying to access something as simple as the home
page, instead of a response that says “keep out” more explicitly, like
a 403 error (access forbidden).
I have verified that the problem is down to the user-agent string,
which means I can reproduce it with a simple wget command, without
actually involving Firefox at all. Here’s a command to reproduce the
error, using the exact same user-agent string as my current version of
Firefox would present:
wget --user-agent="Mozilla/5.0 (Linux x86_64; rv:146.0) Gecko/20100101 Firefox/146.0"
https://bitbucket.org/
If I fiddle with that user-agent string in various ways (like changing
the version number), the access will succeed. You can try this for
yourself.
