Why are eBay, Twitter, Wikipedia, Google, Bing and Amazon extensions listed in profile without permission or removal option in add-ons manager?
Those two are not bundled with Firefox. Defaults are included in the omni.ja file, so they can't really be removed. And last time I checked it, they couldn't collect any data. This search engine file contains only manifest with an URL to the search engine, list of parameters and translations.Read this answer in context 2

These are not extensions but search engines. A number of search engines has been in Firefox since almost beginning. Now the only change is that they are listed on the about:support page.
Two questions: Not all search engines are listed as extensions, e.g. IMDB and wiktionary. Maybe these two were not defaults? When I remove search engines on Options Search page, they still show up as "true" in profile list, even after restarting Firefox. CCleaner still shows them as "disabled" plugins, but they returned as "true" in profiles after a restart , so there is no way to remove them from there now either. So can they actually be removed or would that negatively impact operation? And do these extensions collect data even when not in use? Thanks.
