I have tried all the troubleshooting steps of uninstalling, reinstalling and backing up my profile but on every machine after one session or one time instance and if I have to close Firefox or restart my workstation, I can no longer launch Firefox. It leads me to believe there is some kind of profile issue or corruption with my account but for months I've been battling this issue and can not resolve it. I do remember getting some Firefox window showing the Profile option or Create Profile and I believe nothing was selected. I proceeded to select the Profile on the left and it seems after that is when all the problems started to occur. If anyone has experienced this or can assist, I would greatly appreciate it.

I'm on week 3 of attempting to import my firefox data I'm stuck on the already synced to profile create another. I am unaware that I have any profile at all and I don't want any profiles. Is there any means at all of retrieving my passwords and bookmarks from my old laptop without having to deal with this crap?

I receive this Error msg trying to access Settings option in the AJC epaper section https://editions.ajc.com/shortcode/AJC412/edition/f117d96a-c78b-4df3-4b6a-0e587f6cfd22 on a Firefox Browser:

Application error: a client-side exception has occurred (see the browser console for more information).

Every time I access my bank's website using Firefox I get a pop-up telling me to "manage online experience". After I "manage" it, it appears on every page I go to on the bank's site (ie. savings account or chequing account etc.) I have white listed several of the pages in Privacy and Security but this has no effect. Obviously I am missing something. Can anyone give me guidance? Thx.

I need to update my email to my new account. I list it as my secondary and need to make it my primary email. When asking this question I got a response that there was a "make primary" button next to the secondary email that you could use to perform this task. My account does not have that option. I changed my email last year and need to correct it for my Firefox account. Please help.

So I guess my Firefox update to ver. 147 from 146 by its auto update feature, but I realized all the past personal data (ie, history, cookies, passwords, profile, etc) was gone.

I have Mozilla Account (I think it's the same as Firefox Account back in the old days), so my personal data is now retrieved from some device as far as possible, but I lost local personal settings like Shortcuts on the main page on my laptop,p which is the main device to do everything.

I can't help what happened to me, and I will rebuild what I used to be on that day, but I am curious if it's just me, or there is some logic to cause this data loss.

I find that when I reopen Firefox, many of the tabs in a group are duplicated, appearing both inside and out of the tab group. Is there a fix for this or something I can do? I'm on Firefox 147, on Windows 11. Thanks.

Hi,

On the "Your Firefox has updated" page, I recently found out that in addition to Firefox Sync, you can also create a backup in the form of a local file. When I try to follow the instructions on the support page for the function (here I get stuck. For some reason I am only allowed to choose a file to restore my data, but I am not allowed to create a new backup. I have tried refreshing Firefox and even creating a new profile, but both have the same issue. I am not seeing a "manage backup" button either (see screenshot).

It's not the end of the world thanks to Firefox Sync, but I would like to get it working as a nice backup :)

Thanks in advance for any help you guys can give me!

With the update I lost everything, bookmarks, passwords, extensions, and themes that extensions gave me.... LIKE WTF did you do? I need to get all my stuff back as it was, just on the extension that let's you create a theme, took me an entire day and maybe more to be done, and by day I mean more than 24 hours, now I don't even got my history, bookmarks, NOTHING!!!! I need my stuff as it was, I will be waiting for a response, a proper response on how to get all back, if not please let me know so I could move to another browser like Brave... I spend a considerable amount of time in Mozilla and all the features, all gone, and because of this I didn't switch to Brave

I am unable to open my profile on Firefox. I am using desktop and windows 11. I am typing this question on DuckDuckGo browser because I was unable to go in. It will not let me search, open new tabs, refuse to open new tabs and even to click on settings. I also tried to delete it in an attempt to log in again but it won't even let me delete it. The image I shared is all I see. No bookmarks, shortcuts, ways to do settings and other things. Thank you!

The primary email that I have For my account is no longer active. I can't use that to sign in. Then email is arris@reagan.com. I do have a secondary email. it is mystikog@protonmail.com. Your system wants to demand that I use that primary email address. I can't do that. Can you help me?

I only have one profile, the default one , I clicked something ; Firefox closed and when I opened it again I had to create a profile again , and everything I had, bookmarks history, was lost . How can I recover it , or go back to the first default profile, why is it even possible to exit firefox in any way and not be able to go back where you were.

I have set Bing as my home page when I start Firefox (it has been this way for years). This morning when I started Firefox the Bing home page only partially loaded. The home screen picture of the day won't load and I can't search with it. The only thing that works is the other bookmark tab. I also have Bing in those tabs but the same thing happens when I try to start it from there. I have shut down and restarted my computer, still happens. I have downloaded the latest update of Firefox, still happens. I don't think doing anything with Bing will help, since when I try to start it from the saved bookmarks tab or type it into the address bar it still won't load. I also started Microsoft Edge and it loads fine from there. Although, I just started Chrome and the same thing happens there, it only half loads, so not sure what is going on. I am not tech savy, so am a little uncomfortable with deleting Firefox and re installing it myself. Not sure if I would loose all my saved bookmarks. Can you help.
