It happens on all my sights, ie: Facebook, etc.

Tonight Firefox updated itself and when the routine finished the new default-release profile did not contain any of my data including bookmarks.

I tried to launch the profile default in a new browser but this was empty too.

can anyone help me locate my data and restore it in the new profile?

I continually get error messages for webpages. I turn off my VPN, clear my history. Not sure what else I need to do. Last one was the webpage for Lindt Chocolate. Come on. Why am I getting error messages for this? I have been on this page before. There are other places also, like Macys. Getting fed up with Firefox.

When I launch Firefox, it uses well under 1GB in memory, but then it starts to increase that amount quickly in just a few minutes and gets up to 50+GB, causing error messages to pop up repeatedly until it uses all resources and locks up my computer. I have updated my MAC OS and the Firefox app, uninstalled the Firefox App and still have the same problem.

Please help

After creating yesterday a new Folder, today is not in the Bookmarks under the Star. Under three bars, Bookmarks, Manage bookmarks it shows there the web pages I put there yesterday. What is going on?

It has been two times now where I will open firefox and suddenly all my profiles are gone. I have tried everything to try to get them back like trying to get "old firefox data" back or about:profiles, but there is literally nothing to recover. All of my bookmarks and passwords are fine but I have to log in to everything all over again and reset my home page with all my shortcuts. it is extremely annoying, especially when I use up all the shortcut spaces. It prompts me when I start firefox to create a profile, sign in again, and set firefox as my preferred browser. I have been using firefox for about a year and havent had this problem until a couple of weeks ago. What can i do to avoid having to do this again in the future?

I lost my bookmarks and toolbar and cannot save any new bookmarks. I found the backup for the bookmarks but I am unable to restore. I also cannot find my profile file either. What can I do?

I got a new desktop computer and can't access firefox. My existing account is still under my old email ([edited] @q.com) and has been decommisioned. My new email is [edited] @myctl.net. I cannot sign in because I forgot my password for q.com which no longer exists, so I can't receive an email to change password. I am at a loss how to fix this... Can you help me please. I had sent you my new email back a few months ago so I thought it had been changed to myctl.net but it is not. help please, I am so frustrated. thx for your help

I can't open Firefox at all, so I downloaded Firefox again, before I got your message. The Crash ID: ⁨bp-958359b9-d3d4-4cba-aa19-4dcbc0260313⁩

That is the only one, not five crash ID's. I couldn't open Firefox to find an omni.ja file.

I can't import or access my bookmarks or passwords on the new Firefox I installed. Would you please be able to help with that?

Wenn ich mich auf einigen Seiten anmelden möchte, erscheint dann dieses Fenster: ' Zum synchronisieren anmelden' 'und probieren sie andere Schutzwerkzeuge von Mozilla aus'. Ich möchte nichts davon, ich möchte mich nur ganz normal anmelden.

I have just downloaded NordPass Password Manager. I think I have added an extension for this in Firefox, but I can't tell if it has been successfully added.

I am using Windows 11 Home Version 25H2 OS Build 26200.8037 64 bit operating system

I need help setting my passwords in Mozilla and Firefox. I'm also confused as to what is the difference between the 2 entitities. If there is anyone to guide me would be appreciated.

My sound does not work when using Firefox. But when I switch to the troubleshooting mode in the "Help" menu, the sound works normally. I did not make any changes to sound settings. Sound was fine last night and did not work when I woke the computer up this morning. I am using Windows 11. Going from troubleshooting mode back to normal mode causes the sound to stop working again.
