STR: Set Google as the default search engine In the search box, type "100 + 3" with no quotes See that the suggestion offered is "103". In the location bar, type "100 + 33" with no quotes ER: The location bar should have "103" as a suggestion. AR: The location bar doesn't have any suggestions. If the query is "100+ 33" then the location bar will show "103" as a suggestion. This may have been regressed by bug 1184960 but the patch in that bug doesn't look like it affects additions. Marco, do you know what may have caused this?

should be debugged, I have no idea off-hand. Did you confirm the problem is bug 1184960? why didn't we have a test for this if it was important?
I wonder if we are removing the + cause it's the restrict tags char OR if _prohibitSearchSuggestionsFor is throwing.
