I am signed-in to my Firefox sync on my work and home computer, including syncing add-ons.

I was testing limited add-on installation to approved add-ons in our enterprise on my work computer and inadvertently removed all of my extensions. Without thinking it through I performed a manual Firefox sync on my work computer, which I fear has synced the extension removal to Firefox sync (the opposite of what I wanted to happen).

When I got home I immediately removed add-ons from Firefox Sync, fortunately it seems before any changes synced to my home computer. So I have all of my original add-ons on my home computer, with add-on sync turned OFF.

What's the easiest way of restoring the extensions to my work computer from my home computer? If I enable sync of add-ons on my home computer, will it

1. sync my good add-on configuration from my home computer to my work computer, or
2. sync my bad add-on configuration from my work computer to my home computer?

bold text WHY THE FOOK DOES NOT MOZILLA BOOKMARK SYNC NEVER WORKS???

Lately, mobile firefox has messed up everything. If i look at bookmarks, theyre mostly there, but arrangement is nonsense. Not alphabetical, not in any order. just thrown in randomly into bookmark folder it looks like. VERY HARD to find any bookmarks.

Bookmarking stuff on desktop, then going to phone and trying to sync bookmarks, having to log out and relog in to mozilla sync for about 10 times on both mobile and desktop, and at some point it randomly might sync bookmarks, but if it does, it also messes them up. and impossible to find anything in bookmarks.

Seems almost like someone took a bookmark files in hand and shuffles them a lot, and then placing back, to mix up their order totally.

WHY?

Ive been using mozilla for years and years now, but lately in past 2 years, mozilla, especially mobile version, is NON WORKING PIECE OF CRAP...

So fed up with this issue im too freaking tired to explain it better. SYNC DOES NOT WORK, AND WHEN IT DOES IT MESSES UP EVERY BOOKMARKS ORDER, PLACING OLDEST AS NEWEST AND SECOND OLDEST INTO MIDDLE PART, NEWEST INTO SOMEWHERE IN BETWEEN, scrolling trough all 100 bookmarks to find the latest one you just added, makes no sense whatsoever.

When I booted up Firefox today, I noticed a good chunk of my tabs were gone. They were nowhere in 'closed tabs' in History, nor in recently closed windows. In trying to restore them, I've now lost ALL of my open tabs with no clear way of getting them back. I have no idea what to do. 'Restore previous session' is not an option available to me.

I have to do a clean install of Windows, how do I save all my firefox bookmarks and passwords as well as Thunderbird addresses and any other info I might want to import back into Firefox and Thunderbird once I've installed windows again.

I shutdown my laptop. When it came back up, my fire fox pages were gone. I have the sync option on so I don't know why I lost all of my stuff, files, and documents.

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?

Hello, I keep getting the General application error message when want to sync my account from PC/laptop to mobile device. Could you please, assist me here? Thank you. Vladimir

For the second time, FF opened w/o restoring the previous session's tabs. The first time I was able to restore the tabs. This time I can't. And can't figure out how to fix it or why this is happening since I have the restore previous session box checked.

As I follow the instructions and get to the scan my PC bar code on the PC screen with my cell phone it causes the computer to respond which is only to give me an error that the PC is not paring or just sits on the same screen with nothing basically on it.

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.

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.

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
