Stack trace indicates firefoxtree bug. You should disable it for right now as a workaround.

A user reported that the extension was attempting to access an unknown
attribute on a repo instance. The backtrace indicated filtered
repositories may be involved.

The extra localrepository class for Firefox repositories provided
only a single method, which didn't need to be on a class. To match the
recent move of pull() into a module-level function, we move the
remaining class method into a module-level function and remove the
custom class. There should now be no issue accessing this function on an
unknown type.

Unfortunately, no test for the underlying issue is included. However,
the solution does treat the symptoms. There may be a bug still
lingering, likely around calling the firefoxtree code when it shouldn't
be.

Please test the patch and let me know if this fixes it.

Comment 4

[Yasaswy Kota [:caber]]

The patch seemed to have worked. It was able to clone the repo without any issues.
