When i go to "about:memory" and do a measurement to see whats eating memory i find extensions that are nowhere to be found in the extension manager nor in the folders where the extension files are. they are: - Extension(id=wikipedia@search.mozilla.org, name="Wikipedia (en)", baseURL=moz-extension://8551 - Extension(id=webcompat@mozilla.org, name="Web Compatibility Interventions", baseURL=moz-extensi - Extension(id=screenshots@mozilla.org, name="Firefox Screenshots", baseURL=moz-extension://486 - Extension(id=pictureinpicture@mozilla.org, name="Picture-In-Picture", baseURL=moz-extension:// - Extension(id=google@search.mozilla.org, name="Google", baseURL=moz-extension://13f3307a-648b- - Extension(id=formautofill@mozilla.org, name="Form Autofill", baseURL=moz-extension://dfdf20df- - Extension(id=ddg@search.mozilla.org, name="DuckDuckGo", baseURL=moz-extension://c8eb7a13-e1ab - Extension(id=bing@search.mozilla.org, name="Bing", baseURL=moz-extension://424719d2-8ccf-4c8e- - Extension(id=addons-search-detection@mozilla.com, name="Add-ons Search Detection", baseURL=moz- (the names are cut thats how it shows and at the end there is a "..." i cant select) I tried looking everywhere and i cant find where are this extensions to delete them. i use the google website to do searches so dont need an extension, i dont use duckduckgo at all, i dont use bing at all, i dont use the screenshot feature, i dont use the picture in picture thing and also i use the wbesite if i want to go to wikipedia. I would like to know how to erase them entirely since i dont use them and they are eating memory.
