Firefox 技術支援討論區

Hello, I need help. I downloaded and installed Firefox (latest version), the icon appears in the taskbar, but when I click on it, FireFox does not launch and I always get the same error message. I uninstalled, reinstalled, restarted the PC, but I still have the same problem, even starting from firefox.exe in Windows (C:) >Programs>Mozilla Firefox. Could it be possible that Microsoft is blocking the launch of Mozilla Firefox? Thank you in advance for your help. Attached is a screenshot of the error message. Fortunately, my Mozilla Thunderbird (15.4.2 (64 bits) works fine...

how do i open/load all firefox tabs from another device into active tabs on this device? should be more intuitive and direct than having to navigate 4 levels deep into menus: view > sidebar > synced tabs > open all tabs

New computer (Windows 11) shows 'Old Firefox Data'. Opened hidden files. Using File Explorer found Profile Folder & renamed it 'old'. Copied and pasted 'Old Firefox Data' as new profile. Firefox would not open. Had to remove etc and Firefox worked again. Thought this maybe the easiest way to get my Bookmarks back.

PS Presume Profile Folder does not contain Thunderbird Addresses?

After installing Thunderbird i had first download problems for new Firefox Versions. I tested around, installed everything new and found the solution. Somehow the Maintenance Service didn`t work properly on my machine and after deinstalling and restarting i can update firefox again. Problem remains: When trying to install Offline Languages , see picture, i get the message that it does not work. I tried everything possible, including reinstalling and deleting all old profiles (was a lot of work). Any ideas?

I have been using Firefox for quite some time. Suddenly it stopped working on my computer, I tried uninstalling and reinstalling, but I keep getting a message that there is a problem with the download and installation. Can anyone help? Let me know if you need any further information. Thank you in advance.

How do I import the firefox passwords I saved as csv file from firefox into firefox. I am not importing from a different browser which is the only option offered. I'm importing from the newly created csv file as instructed by firefox.

I will be receiving a new HP Laptop to replace a 2013 Dell Inspiron desktop and would like to to transfer my Firefox browser, settings and bookmarks when it arrives in a couple of weeks. Can you help with the easiest way for me, who has some knowledge but not the greatest at Tech. ? Thank you !

Hi, I lately found one of my old firefox os phones (Alcatel One Touch Fire C). I tried connecting it to the internet and updating it bus it said that there is no internet connection. Is there a way to update the phone?

My laptop had windows 10. I backed up both its drives, C and D, in their entirety to an external drive and installed Linux (pop!_os), but forgot to open the browser one last time and export current tabs, bookmarks, passwords, history and so on beforehand. I believe I should have the unexported files in my backup, as the Mozilla folders are there. What files do I look for in the backup of my drives and how do I transfer them to my current installation of Firefox?

I recently got a new computer (HP Dragonfly) and set Firefox as my default browser but when I click on a link from Outlook it opens in Edge. I'm using Windows11. I have: 1) Confirmed in Firefox settings that Firefox is the default 2) Confirmed in Edge settings that Edge is not the default browser 3) Confirmed in Windows default settings that Firefox is the default browser 4) Ensured in Outlook-Options-Advanced that "Open Hyperlinks in from Outlook" is set to "Default Browser" 5) Uninstalled and reinstalled Firefox. Also restarted my computer several times And yet, clicking on links from Outlook continues to open Edge. Please help I really don't like Edge!

I'm desperate for some help here. I'm a long time customer of Mozilla, and have used Firefox for many many year. Recently, my hard drive was erased, I lost all my data, and I've got a new computer that I'm setting up I'm trying to sign into my Firefox but I don't have the password. I go through Password reset options, and it send a code to my email ([edited] @mindspring.com) and the spam filter is filtering out the email, so I cannot see it. I'm stuck in a loop! I cannot get the passcode and cannot sign into my account. I just need to chat with someone to help me. Please call my call when available.
