Re: Removing "MathML View Source" menu item? [was: Can we remove nsIEntityConverter?]

[J. Ryan Stinnett]

As an occasional contributor to view source, I think it would be nice to
remove the MathML support from m-c like you are proposing, as it definitely
increased the maintenance burden when we reworked view source into a tab a
while ago, and my assumption is the usage of MathML view source is
relatively low (though I currently have no data to back that up).

Looking at the add-on, it seems to miss one feature: Currently in m-c, you
can select a portion of a MathML expression, choose "View Selection
Source", and see the MathML source for the selection. If that's added to
your add-on, I believe you'd have feature parity with the existing MathML
view source support.

I filed https://bugzilla.mozilla.org/show_bug.cgi?id=1365626 to remove
MathML view source from m-c.

Right, I had opened
https://github.com/fred-wang/webextension-mathml-view-source/issues/7
for missing features. I don't know exactly how important they are, though.

Thanks, maybe a first step would be to remove the usage of
nsIEntityConverter as Henri indicated as I don't think it's an important
feature (this is
https://github.com/fred-wang/webextension-mathml-view-source/issues/6).
