I’m running Firefox 131.4 (46621) on my iPhone 12.

I’m setting up a new Mac, and I’m trying to sync the freshly installed Firefox (132.0.1 aarch64) with my other FF instances.

The sync instructions ask if I have FF for mobile, then provide a QR code and give these instructions: 1. Open Firefox on your mobile device. 2. Go to the menu /// on iOS and tap «Sync and save data» 3. Tap «Ready to scan» and hold your phone over this code

There is *no* «Sync and save data» menu item, and I can’t find any other location where I might scan a QR code.

Er, help?

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

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 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.

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?

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.

Hi All

Quick Question - I was stupid and reset my account forgetting I had a recovery key so lost all my data. I realized an old iphone still has most of my bookmarks - how can I export from Firefox iOS app without syncing with my firefox account (which will then wipe out the data)

is this possible? Or could I create a new firefox account, then login into on my phone while keeping my bookmarks? Then export when the new account sync my old phone's data by logging into the new account on my computer? Thanks!!

The font size in "Manage Bookmarks" is way too large, both in the sections list menu on the left and the list of bookmarks. I checked my userChrome.css file as well as the layout.css.devPixelsPerPx entry in about:config and there's nothing there to explain why only the "Manage Bookmarks" text is so large.

It's possible I changed a setting somewhere that's causing this. But I'm stumped re: what setting might be controlling the font size in only that UI. All other Firefox text sizes are good.

Thanks to anyone who knows where I should be looking

Firefox 134.0.1 (64-bit) Windows 10

when attempting to move Firefox bookmarks to my new computer, I click import data within the Firefox page. The computer asks me to select the file. I have no idea where the bookmarks reside and cannot find a file. What is the procedure to get this done?

I've just transferred from one Windows 10 install to another, and wanted to transfer my Firefox profiles along with me. Initially when I transferred over my main profile, the addons worked at first but broke after a short while (specifically there were still as many addon buttons in my toolbar as before, but they were all blank and did nothing), and wouldn't restore after shutting down and reopening Firefox. At first I tried disabling and reenabling each extension, and that worked, but after shutting down and reopning Firefox, they were all broken again. I looked for fixes and tried the solutions in this ask: https://support.mozilla.org/en-US/questions/1260445; first, I tried jscher2000's solution of "deleting" extensions.json by renaming it, but it only fixed a couple addons (BitWarden and uBlock Origin, mainly). Then I tried cor-el's solution of deleting combatibility.ini, and that still only had BitWarden, uBlock Origin, and maybe one or two others working - it also seemed to slightly further the problem, as the toolbar was now set to default without even the blank addon buttons, and the extensions overflow button now just opened about:addons.

But, then I deleted the profile and copied it over again, but this time I preemptively went into extensions.json and changed all the paths to the new correct path (I also did so for the one path address in pkcs11.txt just in case, because it was the only other thing that came up in a search in the profile folder that had that hard-baked full path that might need updating; I don't know what pkcs11.txt does but I just wanted to be sure), and then (not sure if this part matters quite as much) did Create a New Profile and selected that existing copied-over folder as the folder for that profile to use. Lo and behold, all my addons worked! And they've continued to work as normal and not break through several times of closing and reopening both that specific profile and Firefox overall, and even with a couple shut downs and restarts of Windows.

However..... I tried doing that exact procedure (copying over profile folder, editing the paths in extensions.json and pkcs11.txt to be the new correct ones, Create a New Profile and selecting that folder) for my secondary profile, and yet still most addons end up nonfunctional with a defaulted toolbar and extension overflow button opening about:addons just like in the main profile after I did the compatibility.ini fix (even though I didn't even touch it on this profile). After several tries of doing that with differences in naming of the new profile, or also trying to delete compatibility.ini, still I got the same result. Then I tried doing the "disable and then reenable each extension" thing again like I tried first on my primary profile, and it brought the extensions back and in their correct order in the toolbar, but when I exited Firefox and reopened it, they were back to the multitude of blank buttons (which, at least, was a change from before). I have no idea what's different, as far as I'm aware I'm doing the exact same thing that worked on the first profile yet it's still ending up broken.

I've also now tried copying over a third profile in the same manner, and it works perfectly just like the first/primary profile did. But the second profile still just will not work.

with the new function of Tab Groups i was wondering if it is possible, or can be added in the future, to sync existing Tab Groups to all or specific devices in order to access created groups on my private Macbook to my work Windows Firefox.

thanx for any reply

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

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?

After a routine system restart due to display driver crash my Mozilla Firefox ceased to work, displaying a broken link. After some messing around I decided to reinstall the application, but when I did it was an entirely new instance with none of my local saved data (bookmarks, passwords, history etc). I've been able to restore my bookmarks, but not my passwords. I've found the relevant key4.db and logins.json files pertaining to the older intall, but I have no idea how (if possible) to install them, and I assume there would only be a compiled csv if I created it.

Help!
