I have custom search engine added into Firefox search bar. When I enter there e.g. "Who am I?" it gets passed to custom search engine as "Who+am+It%253F" rather than expected "Who+am+It%3F". Result is that search engine returns empty results set.
It works fine on e.g. Chrome.
Also was trying some other OpenSearch search engines e.g. Wikipedia or DuckDuckGo in the same Firefox which work just fine.
Do you have any idea what can be the source of issue?
It looks like the searchTerms is encoded twice or something like that.
