Diễn đàn hỗ trợ Firefox

I'm currently using a Windows 10 desktop computer most of the time, but will need to use a Windows 11 laptop for research travel several times over the next several months.

Will it be possible to copy my profile from Win 10 to the Win 11 computer, use the Win 11 computer for a few weeks, and then copy the profile back to the Win 10 computer?

Or is there something different about Firefox working with Win 10 or Win 11 that would keep this from working for me?

(BTW: Using Sync would probably not be feasible.)

Advice will be much appreciated!

Hello.

Lately i found strange bug in FF 119.0 (ppa - deb, not snap version), ubuntu 23.10 I can't download any file to mounted ntfs volume. Firefox instead creates thousands of empty files. Once it was 10001 or 10003 other time it was 20000 of files. I tried private-window, no change. I have removed all add-ons - no change.

For example i was trying to download https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/virtio-win.iso and i ended with (only few last lines):

-rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9989.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-998.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9990.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9991.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9992.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9993.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9994.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9995.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9996.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9997.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9998.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9999.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-999.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-99.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest-9.exe -rwxrwxrwx 1 root root 0 2023-10-27 22:23 spice-guest-tools-latest.exe

I can download the same source files to the same location with other browsers without problems. Thank You for Your help!

Hello, I recently migrated to a new MAC and now when I download a file and click on "show all downloads", it opens the about:downloads tab and not the downloads list from the library. Is there any way to force Firefox to open the Library when I click on see all download please? Thanks

I have a problem with opening files: Mozilla keeps saving them and ignores temp folder. I tried to modify browser.download.improvements_to_download_panel in about:config, but nothing happened. Can anybody help me?

Hi,

Because numerous things did not work with version 116, I downloaded previous version of the browser and installed it. When it started it said something like "you are trying to use the previous version so some things may not work, would you like to create a new profile?" and there was a choice "yes" or "exit". So I chose "yes" - because how creating a new profile could mean something bad? But it did - it deleted all my bookmarks and settings. I have used mozilla for years, everything was in it. How to restore the bookmarks and everything back? It, by the way, upgraded itself to 116 anyway.

i use the same add-ons on my desktop and laptop. i open my laptop and click on synchronize and later i open my desktop. two of these add-ons on the desktop have disappeared! this is not the first time. what can do i, how can install it to prevent it does not happen again?

As the title says i have enabled always ask where to save files but when i try to download files it saves them in my Download files most of the times.I didnt have the problem yesterday. Can you please help.

Greetings,

When I started getting msgs saying my browser was no longer supported, I checked my version. Firefox says i have v115esr and that it is "up to date" - i.e. no update available at this time. I assumed I was getting the brush off from those web sites.

Why did Firefox not bring me up to v124? I get a "download update" probably once a month. It's been giving me a new variation of 115esr all along.

I've now downloaded 124 from your site. What do I need to do so that I stay current in the future? Thanks John

I've installed a new version of Ubuntu Linux and - as recommended on this page's FAQs - backed up my firefox profile, than copied it into the profile folder on the new os. Now Firefox tells me "You've launched an older version of firefox" and forces me to create a new profile :( Also loading the old profile in "about:profiles" leads to the same result

How can i restore at least my passwords? (When i try to copy only 4.db and logins.json from the old to the new profile, i get the same result)

I can't find an "import old profile"-function anywhere...

Prior to getting some desktop PC upgrades that required a new install of Windows 11 and a new install of Firefox, I backed up my entire PC (yea!).

Now that I have re-installed Firefox, I see that I have none of my saved bookmarks and so I want to restore the Firefox profile - all of it or at least the bookmarks.

I have tried following the Firefox instructions for this, but am apparently not doing it right.

I can't seem to locate the bookmarks file, for starters, in my backed up files. I find the profile but I don't find anything like places.sqlite.

Can someone help me so that I am locating the right (and complete) files, copying them correctly, and then switching to the new/old profile correctly?

Thanks in advance.

Hello,

I've set up Firefox to ask before updating, so I was taken aback by the fact that today, an update was automatically installed without Firefox asking me... (I was updated from 97.x to 98.0)

It is especially frustrating, as the mandatory "Restart" screen is broken when using several profiles, at least under Debian.

Let me know if you need more information.

Best regards,

Adonis

I have Mac 10.12.6 on an "early 2009" 27" iMac. I'm waiting for the new 27/32inch iMac until I upgrade hardware and operating system. The release notes with FF V115 say in part " Users on those operating systems will be migrated to the ESR 115 version of Firefox."

I want to clarify that when I update to FF 116, FF will automatically install the ESR version, or will I need to do this manually? Also, will this update take a long time, like FF will be installing a totally new (ESR) version, rather than "just" the usual update?

My laptop died but I have been able to rescue the SSD and turn it into a USB connected external drive. I can see all data from my old PC.

I have tried to copy all of my User, Local Apps Data Mozilla Profile data folders to my new Laptop but the data does not appear when I fire up Firefox on the new laptop.

The old laptop folder was c:\Users|Phil, the new laptop is C:\Users\Phill {setup of new PC added a second L to my name}

Is this an issue ?

Firefox saves files that I only wanted to open with another application.

I checked the previous solutions in the forum, but they did not work for me. (Windows 11) I changed in system> general > download , applications > the app to open that file type and it works, but besides this Firefox keeps saving the files in the default download folder.

I tried also about:config browser.download.improvements_to_download_panel to false. browser.download.start_downloads_in_tmp_dir change to true No change - still saving copies.

On Mac OS 14.4 Firefox hangs on launch and crashes, requiring "Force Quit" when I try to Refresh or Troubleshoot. Uninstalled and reinstalled multiple times, and restarted computer several times. Have spent several hours trying multiple community suggestions to now avail.

I am not a programmer, but am able to follow instructions. I clearly need someone to hold my hand and walk me through the solution. (I even checked out the Kaspersky suggestion, but cannot install it because Firefox cannot connect to the Internet.)

I have downloaded and saved "Raw Data.docx" and "Application Basics tex.docx" from one of the crash reports.

P.S. On this question form Firefox guessed that my operation system was Mac OS x 10_15_7, but it is 14.4

Hi, just bought a new laptop which is loaded with windows 11, and I cannot download Surfshark vpn, I go to google and it will not even open any surfshark page, I assumed it must be something to do with safesearch, so I clicked on the safesearch button but it does not give me the option to turn it off it just states 'You don't have permission to change your SafeSearch setting. It's locked by the device or network that you are browsing on' !! how do I get over this? any help appreciated,

I'm trying to migrate to the newest version of Firefox on an old installation of Fedora. I've downloaded and unpacked the installation files but can't identify the installer. All I probably need is the name, as I know how to make it executable and run it once I know what file it is.

After a crash earlier today within my 32bit install of Firefox, I upgraded to the 64bit version. Since then I have not been able to play videos from sites that utilize DRM.

I have tried the following:

1. Check and Uncheck "Play DRM content"
2. Check for updates while in the addons related page.
3. Checked my hosts file which is blank
4. Stopped my AV and attempted to update as well as Enable/Disable Play DRM
5. Get a 404 when attempting to go to "redirector . gvt1 . com" site.

When I looked in my profile directory, I noted that both the "gmp-gmpopenh264" and "gmp-widevinecdm" directories are empty. I found and downloaded the most recent openh264 dll for windows 64bit. Firefox continues to say "OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly." I have not found the most recent wildevine version so I have not tried to update it manually.

Could there be something squirrelly with my user profile that needs to be rebuilt? (I can export the bookmarks, etc) The 32bit Firefox crashed with no messages while watching a live YouTube stream. I just installed over without uninstalling the previous version. I was afraid of losing my current settings. The crash caused my "previous session" to be lost.
