Firefox Community Forum

Back around February (2025), the full screen mode by pressing F11 quit working. Clicking the diagonal two pointed arrow in the application menu didn't do it anymore either. Both actions only toggle the bookmark bar. I've tried reinstalling, and waiting for further updates. So far, still no luck. I've since moved on to using another browser, since I often want this feature. Does anyone have the same problem or know how to fix this?

Gdzie w pzeglądarce Floorp znajduje się moduł lokalizacji? Będę wdzięczny za udzielenie mi odpowiedzi na adres mejlowy [email removed]@vp.pl. Pozdrawiam z szacunkiem Mieczysław Pajek

How to remove thumbtack icon from quick link icons on the homepage of Firefox.

The little thumbtack icon was by the name of the quick link on my home page. I updated to 139.0.4 and now thumbtack in top left corner of quick link icon. I want the thumbtack gone.

My bookmarks from an older Firefox version are in JSONLZ4 format and when I convert them to html for import to a current Firefox version it loses bookmarks. Firefox will not allow me to import the original JSONLZ4 file. How do I import my bookmarks?

제목 그대로입니다.

절대로 테마가 아닌 새 탭 페이지 즉 아무 웹사이트도 접속하지 않은 상태에서 이미지 변경하는 방법입니다.

오늘 업데이트가 되었다며 이미지를 변경하라고 해서 아무 이미지를 넣었다가 되돌릴 방법이 없어서 1시간을 낭비했습니다.

절대로 테마아닙니다. 새 탭 페이지입니다. 어떠한 부가기능도 사용하지 않았습니다. 이러한 문제가 아닌지 검토하라는 답변을 줄 경우 무조건 최악의 평가를 내릴겁니다.
