Firefox Community Forum

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.

Dear Mozilla Support Team,

I am writing to you today to report a persistent issue I am having while trying to access Pinterest (www.pinterest.com). Whenever I attempt to visit the website, I encounter the following error message:

Pinterest Secure Connection Failed An error occurred during a connection to www.pinterest.com. PR_CONNECT_RESET_ERROR

I have tried troubleshooting this issue by:

Clearing my browser cache and cookies. Restarting my computer. Trying a different web browser. Disabling any ad-blockers or extensions. Unfortunately, none of these solutions have resolved the problem. I am using Windows 11 and have attached a screenshot of the error message for your reference.

I would greatly appreciate it if you could provide me with some guidance on how to resolve this issue. I am unable to access Pinterest, which is causing significant inconvenience.

Thank you for your time and assistance.

Sincerely, Hatice Bozkurt

Please help by recovering all my information that i have already filled in the form have failed to access my application form to complete and then submit. please do the needful to rescue me because i just have one day for submission

I'm not sure what type of issue this is, so hopefully I’ve posted it in the right place!

Devices:

• Firefox version 133.0 on 2022 M2 MacBook Pro OS Sequoia 15.1.1
• Firefox version 133.0 on iPhone 16 Pro Max iOS 18.1.1 (*for reference, of checking issue, not where issue is occurring)

Issue Breakdown: While updating my bookmark's tags in Bookmark Manager, my tags all but disappeared and other strange things started happening.

• My tags aren't in the sidebar menu of the Bookmark Manager at all. See Screenshot 1.
• Already tagged bookmarks retained the tags, but I’m unable to edit, add, or remove bookmark tags at all. When the bookmark is selected, the bookmark’s tags, nor any other tags, appear in a list under the bookmarks tags. See Screenshot 2.
• I can locate all bookmarks with the same tag by searching bookmarks in the Bookmark Manager.
• I can move and rename pre-existing bookmarks.
• I can add new bookmarks (confirmed by the blue star beside the address bar on the main browser after exiting and re-entering), but I cannot find those bookmarks anywhere in Bookmark Manager.
• My mobile bookmarks folder isn’t shown in Bookmarks Manager, but I can view 11 bookmarks in my Mobile Bookmarks folder on my phone’s Firefox application.

I’ve tried the following:

• restarting Firefox by quitting the application
• refreshing Firefox through the browser [https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-se...]
• restarting my computer
• clearing the startup cache
• clearing the cache [https://support.mozilla.org/en-US/kb/how-clear-firefox-cache|link]
• restarted in Troubleshoot Mode [https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubl...]
• uninstalling then reinstalling Firefox software

I have no idea what is wrong with it or what is going on. What else can I do?

after reinstalling my system i culd not login to my account i have like 9 passwords and your stopid system blecked my attempts like after second attepmt so i did password recovery and changed it but after that all my sync data are gon WTF!!!!! It makes the sync function pointless and usless for its specially for that purpose !!!!!!!

Yesterday, something went wrong in my Windows 11 desktop (I have a virus program installed). One of the casualties involved corrupting Firefox (it would not open). I reinstalled Firefox without removing the old version. Now I have a new installation but all my bookmarks and other data are missing. There is a folder on my desktop labelled as "Old Firefox data". It is possible to restore Firefox to a previous time (a day ago)? Thank you.

I have a situation where I constantly have to send tabs from mobile Firefox to desktop Firefox. So I use Send tab to device feature. But when sending, manually clicking on the Synchronise now button in the Account menu of the toolbar of the receiving device is often needed, or else it would take a while for the tabs to be received. But I find that annoying and unintuitive.

Is there a solution for it? For instance, syncing Firefox devices more often, maybe just for the sending tabs feature because sync-now also syncs history, and bookmarks.

Hiya all,

My newly refurbed laptop died A Death a little while ago, and I'm prepping to send it back to the seller. I had the browser on the laptop synced with my Firefox account (autofill my passwords for things etc) and have since unlinked it, but I just need to know that the browser won't be autofilling things if the seller repairs the hardware and fiddles around!

The laptop as it stands is entirely unbootable, and while I know I can remove the HDD and delete my files, it's the browser stuff I'm most concerned about.

Thank you!

During a thunderstorm and subsequent power cut my desktop (W10) would not reboot. Nothing just a black screen. My builder looked at it for two days and determined that it was the processor that had failed. I purchased a high spec refurbished desktop (W11) which I am finding a shock at 74, nearly 75. I have the SSD from the old computer in a USB connected caddy. FF is installed on both computers. How can I get the Bookmarks from old to new ?

I am going round in circles. The last Firefox update reset my Firefox on my laptop to default settings including losing my master password. I started to reset all my old settings but when I got to the part where I setup the sync with my phone version of Firefox, Mozilla asked me to log in. My password was not recognised so I hit "Forgot password" having set up a new password using one of my 10 digit authentication codes, I was then asked to log in with my new password, I did this & when trying to do the sync, I am being asked for a six digit authentication code! I have no idea where to find this code. Please help.

Move open account to new computer, old computer died, Firefox[ Mozilla] have all my pass words also, Will not let me open old e mails etc. sync wants cell phone,it doesn't work where I live. thanks john

Hello today i went to a it specialist, he reinstalled my windows and i lost all my backups i had been using firefox for a few days and saved a lot of stuff in bookmarks but now they dont sync i can only sync my old bookmarks from edge.Is there a way to check if my bookmarks were saved on a server?

Hi all,

Fully aware of [https://support.mozilla.org/en-US/que.../1204859], I wonder if there is any way to force a synchronization from one specific browser to others? My scenario is as follows: I use a desktop computer for daily work. This computer is bascially the source of truth. I use literally thousands of tabs, organized w/ Sideberry and multi-accounts containers (~100) (2 profiles in parallel).

From time to time, I use a laptop when commuting or working elsewhere. I'd love to instruct the laptop to receive the latest update (like a git fetch), probably after telling the main computer to "upload" (git push) the latest information and would like to make sure the laptop never can overwrite the desktop information.

Is there any way to implement such a scenario?

Thanks!

This afternoon from 12:00 to 12:26 I visited the website silk-avia.com. on this site I booked a ticket for the date 05/12/2024. when I first searched, I chose 05/12/2024; when booking, the site showed me the date 06/12/2024, but I changed the date to 05/12/2024 and issued a ticket. After payment I received a letter with a ticket dated 06/12/2024. When contacting the airline, they want proof that I chose the date 05/12/2024. but I didn't find it in the browser history. can you help me with this
