Firefox Support Forum

HI! I've been trying to install Firefox on my new Acer Chromebook by following this article: https://support.mozilla.org/en-US/kb/run-firefox-chromeos. However, whenever i get to the last step, it says "no remote refs found similar to firefox". I have no idea what i'm doing at this point, any help?

I currently am running FF vers. 109.0.1 64 bit on Win 10 pro. I don't like what I've been reading about the latest update, my machines are old and I'm not ready to upgrade so I don't want an even more overloaded/uses up more CPU, etc., version of Firefox. I don't have complex needs in a browser, so some of the "upgrades" haven't been useful for me or have made using FF more difficult.

  I found a list of what I guess are older versions but no information was provided on how to choose a version of say v. 110, to make sure it's the right one for my laptop and/desktop (or the one that will work w/the fewest problems) that it's in English, etc.   
  My impression is that FF is mostly worked on by people who have a variety of needs & interests so increasing sophistication is what they want and that's fine, I'd like to keep using FF w/my current machines, w/as simple a version ,ie., useful for an unsophisticated user.    Is that possible?    If so, I'd like to upgrade to 110 64 bit or perhaps 111 64 bit unless either or both had huge security holes, etc and many users found they weren't very functional.   I do have security software.

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?

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'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!

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?

At some point every night, my Firefox (and only Firefox) reverts to version 111 from the latest version. This happens on 2 different Windows 11 machines.

I can only get Firefox to run again by running from command prompt with "-allow-downgrade" option and then updating again.

I usually don't notice until I launch Firefox the following morning and it gives me a message that the profile was created with an older version and to exit or create a new profile.

I've had Firefox open and then it reverts and it gives me a XULRunner error about the profile being used by an older version.

I don't have any special backup or restore software running and the physical files in my Firefox folder in c:\program files\mozilla firefox are being physically pushed to a prior version dated 3/21/2023.

On both machines, I've completely uninstalled and reinstalled and it's good for a day and then reverts.

No log entries for the reversion can be found. It's just back to a prior version.

I've never come across anything like this before and have scanned for any malware or other issue, but haven't found anything.

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.

My HP Omen has 2 hard drives. Originally, Firefox was installed on the C: drive and working perfectly. In order to clear up space, I tried to use the Windows Move feature to move the program from the C: drive to the secondary (and larger) E: drive. Since then, Firefox won't work aside from opening a Firefox window. It will load no pages, settings, etc.

I've tried uninstalling Firefox from both the C: and E: drives. Searched for any remaining files and deleted them. Deleted Old Firefox Data folders. I've reinstalled Firefox, without the option of where to install it, but it still fails to work at all. I get an error message regarding a missing file, VCRUNTIME140_1.dll. I've searched for the file and it's NOT missing. It is in both the Firefox folder and the Windows/Systems32 folder.

I've searched for data in the Users folders that might relate to Firefox but NOTHING seems to work that will allow Firefox to work again. I've tried putting Firefox in Troubleshooting Mode but it won't restart as it says it needs to. It just won't work!

If anyone can just tell me how to COMPLETELY remove Firefox from both hard drives so that I can just do a clean, new Firefox install, that would be preferable. I know how to import bookmarks from Chrome.

If anyone can offer some help for someone who isn't great with computers, I would greatly appreciate it. If you need any other information, please don't hesitate to ask.

I am following all the instructions. It has continued to fail for the past year. I've uninstalled ff and reinstalled ff. I've tried creating new profiles. I can import everything into Chrome or from Chrome to MSE, but NOTHING will import into ff from any other browser.

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.

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...

Hello - I've been looking around the Firefox site, and the Internet in general, and so far haven't found out the answer to my question: how do I get Firefox 104 to work on my Linux Mint 18.2 Cinnamon Sonya 32 bit? Specifically what I haven't been able to determine is whether or not I first need to upgrade my Linux, which I suspect. And if so, what's the minimum level of the OS that is required? I may be overlooking the simple answers, but so far I cannot find them. And so far the Firefox website upgrade feature does nothing that I can detect. Thank you for any assistance - Doug.

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?

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

Hi there,

i'd like to copy my Firefox profile from PC1 to a new PC2;

Last time i tried this, i ended up with PC2 having the same "name" as PC1 in "Sync". This caused weird sync issues, as the system thought my PC2 was PC1 as vice versa.

So, is it possible to copy my entire profile with all addons/settings, BUT, make "Sync" recognize it as a NEW pc ?

Thank you in advance :-)
