I would be grateful for some information on container behavior, i.e. I created "permanent" (as opposed to temporary) containers for sites where I want that site's cookies & site data preserved in a container, so I can click "Clear Cookies/History" (or "Clear... when Firefox closes) and the items stored in PERMANENT containers are left alone, while all else is deleted. "Clear ...." doesn't appear to be respecting the permanent containers I have set up precisely to preserve these sites' cookies & data.

I'm not sure what the point of Permanent Containers is, if not to preserve those sites' data, for the sites' later use when you set Firefox to Clear Cookies and Site Data whenever Firefox Closes (or Clear Cookies & Site Data with one click). I expected it to respect data in Permanent containers, as exceptions. Else why not just use separate Temporary Containers for everything? Why bother with Permanent Containers if everything is going to be deleted when Firefox closes, whether it's marked "Permanent" or not? Is there a solution for this? Thanks, -AnneF

Why is Firefox crashing so often? What changed? Is there something I need to do to prevent his? Once or twice a week or sometimes a day, but It seems to crash when I am just in my Gmail, sometimes 4 or 5 times an hour. Is Chrome a better option?

For days I have been seeing Firefox be very slow to load a page (as in minutes) or stop working entirely. At the same time Chrome works fine. Mac Mail has become intermittent as well. I have uninstalled Norton products and changed Network proxy settings many times. Nothing helps. I have created new profiles. I switch between profiles. I have hacked into my WiFi router. Nothing, nothing helps. Safari hangs up too. Firefox on my android phone continues to work properly when using my Wifi router -the same router my Mac Studio connects to the internet with. I can access my third party mail service via Firefox on my android phone. Both FireTV devices work. I am at my wit's end. At this point I have shifted all of my work over to Chrome.

I have cleared caches. I have gotten rid of all cookies. I have restarted Firefox and rebooted my computer countless times.

Kính gửi đội ngũ hỗ trợ Firefox,

Tôi hiện đang sử dụng iPhone 15 và đã cài đặt phiên bản mới nhất của Firefox. Tôi cũng sử dụng VPN qua ứng dụng Secure Access, được công ty cấp chứng chỉ trên thiết bị di động.

Trước đây, khi sử dụng phiên bản Firefox cũ hơn, tôi có thể bật VPN và truy cập trang web nội bộ của công ty mà không gặp vấn đề gì. Tuy nhiên, kể từ khi cập nhật lên phiên bản Firefox mới nhất, tôi không thể truy cập trang web đó nữa. Thỉnh thoảng, Firefox hiển thị lỗi "This Connection is Untrusted", có biểu tượng "Visit site anyway", và khi tôi nhấp vào, tôi có thể vào được.

Do trang web nội bộ của công ty đang sử dụng phiên bản SSL cũ và không thể thay đổi, tôi cần tìm một giải pháp để tiếp tục sử dụng VPN và truy cập trang web nội bộ như trước đây.

Mong đội ngũ hỗ trợ Firefox giúp tôi tìm cách khắc phục vấn đề này. Trân thành cám ơn

Help! All my bookmarks have disappeared from the Firefox browser. I believe there has been a browser update done by Firefox. I found various ways to recover bookmarks and found a folder named 'old Firefox Data' on my desktop. But all files I try to import give me an error message stating that this file doesn't contain any bookmark data. I tried to import bookmark files and favicons.sqlite files. No luck. I now cannot access bookmarks accumulated for about 10 years. Really need to get them back into this new browser. Any advice highly appreciated.

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.

Well, it is quite simple: you upgraded FireFox last night and now I lost all my bookmarks which is horrible and I really do not appreciate what happened and why? It never happened before.....
