Firefox 社群討論區

I have moved to a new laptop and followed the advice in how to back up and restore to transfer history and bookmarks. However only a small part of the history and bookmarks have come across

I tried to open my Firefox browser, but was unable to. Same thing with my Google chrome browser. I ran the troubleshooter for network problems, but unable to get a solution.

I downloaded a new Firefox browser in the hopes that it would let me access the other browser so I could retrieve all the settings, bookmarks, etc. However, everything disappeared when the new browser was installing.

Is there any way for me to retrieve that information or is it a total loss?

I had dozens and dozens of bookmarks saved, which I backed up a few days ago, and saved the .json file to my desktop.

When I went to open them this morning, they were all gone. I imported the file to restore them, but none of my saved bookmarks returned. It seemed to import a state from 2024.

I have scoured these forums and tried everything that was sugggested, even tips from different forums.

Did this happen because I didn't have a Mozilla account (until now)?

Please please help. I don't have any profile data saved on my computer and I need my bookmarks back!

I'm in the process of exporting my FireFox bookmarks as html files.

In this process I noticed that everytime I save (export bookmarks as html) as a file a location on my disk, then open up that file to inspect/check - I notice that FireFox appends to the exported file rather than replace. Even though it asks if I want to replace the existing file during the save dialogue.

I'm using win 8.1

So, that's fine I though, 'let's' just delete that file and start over. Long story short, it does not work; I did the following.

Before closing FireFox I went into FireFox settings and click on all catagories of History - and cleared. I then closed FireFox then in Windows Explorer went to where the original file (exported html bookmarks), and deleted that file directly from windows.

I then opened up FireFox again and exported the my bookmarks as html to the same location again. Even though that destination no longer has a file from before - when I reopen the just now newly export html bookmark file - I see the contents are the same as before - (I has the appended/duplicated html bookmarks).

It's like instead of exporting the bookmarks I actually see in FireFox, it is referring to some saved information somewhere instead and saving that.

How can I export what bookmarks and folders I actually see in FireFox instead of some internal bookmarks/folders FireFox thinks I have - In other words - is there some file I can delete or setting to clear?

Thanks.

Hi, I hope someone can help me. Please note I live in UK and I have a Desktop Computer but do not have a mobile phone. I use Firefox browser. This is what happened over 2 days Thurs and Friday. 28-11-24 THURSDAY @1.38pm On Thursday morning I used my computer with Firefox browser, and it worked perfectly OK. Then I had to go out shopping @11-15am. When I came back in doors @1.38PM I turned on my computer, it booted up as normal, then a Blue Screen appeared, with a message from Microsoft re back up in Cloud. I have not actually used Cloud before, although I did try to set it up earlier this year but not completed. So, I thought I would try again. This time I tried to register for the first time on cloud, I entered my email address and country, date of birth and then a password. Maybe something else, can't remember.

Then it asked for a code number that it said it had sent to my email, but I could not get that email then as I was stuck in between booting up and the Desktop screen. ( I DO NOT HAVE A MOBILE PHONE) As I did not have the code number, I clicked on, what may have said “not now” or similar message. Anyway, it would not continue so I had no option than to press the back button arrow, top left corner, several times. I think it took me back to the page with choices. I think I clicked remind me in a few days, which took me to the Desktop.

Normally my computer automatically opens Firefox Browser, but this time, I had to open Firefox, still no problem so far and the rest of Thursday OK. I did not try Microsoft Cloud again on Thursday.

29-11-24 Friday @ about 10.15am I thought that when I booted up, it may go back to where I left it Thursday, but no. When I turned on, there was no sign of the Blue Screen or Microsoft Cloud message re Back Up. When computer reached the Desktop, it did not load Firefox but an ERROR MESSAGE. It said. ERROR: PLATFORM VERSION "133.0" IS NOT COMPATABLE WITH MINVERSION >= 132.0.2 MAXVERSION <= 132.0.2 MAYBE TRY TO REINSTALL FIREFOX

It worked perfectly well before I tried to set up Microsoft Cloud yesterday (Thurs 28-11-24) now I cannot load or use Firefox at all, because it comes up with the same message every time. I have tried turning the computer off and back on, no luck.

My worry about Reinstalling Firefox is that I have hundreds of websites saved in bookmarks folders and I am not sure if I would lose them.

At this moment I have had to endure Microsoft Edge which I don't like. Don't put me through any more pain. Can you please help out a pensioner lost in the modern technological world. Thank you David

I would like to be able to download YouTube videos.

Is there a Firefox add-on that will allow me to download YouTube videos onto my MacMini?

I tried Video DownloadHelper and YouTube Video Downloader and didn't see any action.

Do I need to setup settings a certain way to make it work?

What are the steps to make it work?

Thank you for your assistance.

I've never had this problem before, even though I've been using Firefox for 4 years. As soon as I try to connect to an account via Google, or go to Docs/Drive/Classroom, I'm always taken to a “Clear cache and delete cookies” page. So I followed the instructions on the page, deleted all my data and saved cookies from Firefox and even tried to reinstall Firefox completely, but nothing changed, I'm always redirected to this page.

Someone can help me please? I can provide more informations if needed.

Hello,

Referring to your article [https://mzl.la/3TS8WcA] (Import settings and data into Thunderbird for Android) . The first step is : Export Thunderbird Desktop settings

   Click ≡ > Tools > Export for Mobile. 

However, I am running version 128.3.3esr (64 bits) "Nebula" and the menu "Export for Mobile" isn't available under "Tools" as mentioned in the article.

Please advise

Regards

Several weeks ago, I was attempting to upgrade from Windows 10 to Windows 11. In the process, I deleted Firefox (using Revo Uninstaller) and then reinstalled it, downloading it from the Mozilla website. Unfortunately, it didn’t run, giving me, at different attempts, different error messages. In the time since then, I have read many suggestions from many different websites and I have tried some of these suggestions, all with no success – until today. I have just completed the suggestions made on https://support.mozilla.org/en-US/questions/1327628 and Firefox is now back, working. I am happy and grateful, but not finished. None of my personal data came with the currently functioning version of Firefox. Since the re-emergence of Firefox, I have been reading several websites dealing with copy, backup and restore of my Firefox profile. Right now, the path C:\Users\rsuth\AppData\Roaming\Mozilla\Firefox\Profiles\ shows 5 folders: Two of the folders show 11/11/24 as the date modified (probably the date of the download from Mozilla). The folder 0dppjrfa.default contains one file, times.json, dated 8/11/2020. The other folder, ru82tlj5.default-release, has 97 items, most dated 11/11/2024. The remaining three folders are all dated 12/2/24 (today, as I write this). One folder’s name ends .default, the second name ends .default-release, and the third name ends .default-release-thirteen digits. The question that I am asking here is what do I do next to, hopefully, bring back the personal date I had with Firefox before my updating to Windows 11. Should I delete the folders dated 12/2/24? What, if anything, is the significance of the folder whose name ends in 13 digits? I’m hoping someone will be able to tell me how to fix these Firefox problems. And if I can, then I hope to be able to do something similar to help me bring back Thunderbird as well. Thunderbird became unfunctioning at the same time as Firefox. Thank you.

Hello, I've got a bit of an issue with Sync. So, my current sync profile is outdated by ages, and I'd like to delete it completely and update it with all of the information on my desktop browser. But, when I try to enable sync on my desktop it overwrites my desktop profile with all of the outdated information saved on Sync. I can't seem to find anywhere to delete the saved Sync data so that I can upload a new copy.

I hope someone can help, thank you!

The Firefox Sync system is really neat for keeping our booksmarks synced across devices, but what I would also love to see is the option to sync all settings as well, including the changes made in the "about:config" settings.

Across my years of browsing I changed quite a lot of small little things and having to track all of those down every time I set up a new device or reinstall windows can get a bit tedious, so I was wondering if those settings can also be included in the Sync settings somehow - or if such a feature might be planned for the future?

Hello, After the last MacBook Pro M4 update my tabs keep disappearing. This is quite ANNOYING as I use ALL my tabs. Plus when I go to HISTORY there is NO Restore Previous session...so I am losing EVERYTHING. Do I just need to go out to another browser and make them my default? I can find NO help when I go out to your support for my problem. Thank you, Patty

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS.

Hi- I'm trying to setup two step in Microsoft Authenticator. I scan in the QR code from the Mozilla settings and that appears to work. However when I copy the generated code from the app and try to enter it back into the settings in my browser it tells me the code is wrong and thus I can't setup two step. I've tried loads of different authenticator apps and none seem to work. Can you help please? Thanks- Adrian.

For example, say, you have 3 opened tabs in a Firefox (FF) windows. Normally, when you close FF and then re-open FF, it restores 3 previous opened tabs.

But, if you have another FF windows opened at the same time, when you close the FF windows with the 3 opened tabs and re-open back a new FF windows, FF won't restore the 3 opened tabs.

Same thing happens when you have another Private FF windows at the same time, when you close the non-Private FF with the 3 opened tabs, and then you re-open FF, it loses the 3 opened tabs.

That's why you can see 'countless' question about lost opened session, because of the issue above along with crash etc.

Is this a bug or a known feature?
