:nsharpley, since you are the author of the regressor, bug 1885894, could you take a look? Also, could you set the severity field?

I think this is a dupe of bug 1908019, right?

I do not think this is duplication.
Because, It reproduced with newly created profile and I am not using "Clear Recent History" and any related settings.

Not a duplication, but I think a bug 1908019 patch would solve it. I've picked that up from :sclements, so in progress.

No, that bug was for a different issue altogether.
