Firefox Support Forum

Firefox is running very slow and when I try to refresh it as prompted, nothing changes. I'm not very technical and need clear instructions as to what to do next. Also, when I try to access LinkedIn, I can't and I don't know if that is a Firefox or linkedIn problem.

Today I upgraded my Firefox to the new version.... of course I lost all the "Theme", display style etc. etc. ... most of all I even lost the bookmarks. Now that is very inconvenient and time consuming to re do . Maybe some bookmarks needed some input which I may not have available now...

So is it possible to get those back....

Thanks Anil

my firefox browser will not start after I did the fresh up. it states that : Your Firefox profile cannot be loaded. It may be missing or inaccessible. tried to reinstall but still not working

Thanks for your help

THIS program needs WORK! I already added a whole paragraph describing my problem. Then per this pages clicked on the green button below. It took me to a page that said it couldn't find what I was looking for and when I clicked back, I lost ALL of what I had input before - Grrrrrrrrrrrrrrrrr. So here goes AGAIN:

I had been receiving error messages whenever I tried to load FF stating that it was already running. Jumped through all the hoops of how to fix that, including unchecking the read only in profile - BTW. After unchecking that box, clicking on apply now, and waiting for the program to stop doing whatever with the files. I clicked on OK and the properties closed. When I opened it up again - sure enough the read only box was filled in! - WTH - Then I installed the newest version (yesterday and everything worked). This AM when I went to open FF I got the same error message about it running and to close it. I am getting sick enough of this to start looking elsewhere. I have been a FF user for YEARS with NO problems. Until NOW.

When I try to access Firefox on my Laptop, (Windows 7) a message appears saying,

"Firefox Profile Can't be loaded, it may be missing or Inaccessible"

This all came about when I tried to Refresh Firefox, but stopped refressing before it was completed refreshing. Trevor

My son installed Firefox in my computer and he input his Google account as default. He is living in another country and I have to constantly change Google to my account. I've thought that, if I reinstall it the problem is going to be solved, but unfortunately absolutely all the old setting remain, even if I let the "Restore... " box checked. Firefox knows it's been reinstalled. I cannot login on my son's account for privacy reasons, so I cannot delete it. Is there a way to reinstall Firefox from scratch?

Thanks!

I am running with ubuntu 18.04.2 I was having a problem with the snap version of firefox so I downloaded, and installed the non-snap version of firefox. Now I want to delete the snap version and use the other. My problem is that all my stuff is in the snap version. My thought is to save the profile of the snap version and then use that profile for the non snap version, delete both versions and reinstall the version I want to use. before I start, however, I thought I would ask whether that would work.

Thank you........

I just installed the latest Firefox update (67) and when the browser restarted I noticed no web pages were loading. It turned out this was because my uBlock Origin and uMatrix extensions had been completely cleared of ALL data, including their default/pre-defined rules.

All of my extensions data seems to have been cleared. The extensions are still installed, but their settings/data are completely gone.

This is EXTREMELY frustrating.

Does Firefox make backups or anything before it attempts an update? Is my extension data/settings recoverable somehow?

Come on, Mozilla, what are you doing to Firefox recently?!

Hi,

Recently an issue with links and default browser has come up in Win10. When I click a link in Tbird for instance it opens a completely new window (as opposed to a new tab as before). This window has no prefs, logins or add-on on it. It's like a clean install of the app. Am on latest version of FF Portable.

Cheers, N

I restarted my computer and had previously set up firefox to save all tabs, I had a month of work saved here and it was to always open the tabs after closing the program. I also have about 50 sites book marked for my work and everything disappeared with a new version of firefox of course it said on the new landing page that I didnt lose my work or bookmarks everything is gone and I cant find them anywhere nor is there any instructions as to how I can restore it. I rolled back the computer to an earlier date and the system restore point didnt bring back the information either.--HELP

I cannot install or open firefox because I get a message saying the profile is missing so I try to create a new profile and it says an unexpected error occurred.

I reinstalled it a few times but no luck. I flushed my cache Tried developer edition

This application does not seem to work at all.

Today i lost all of my bookmarks and menu settings when i opened my website. I have been a customer of Firefox for many years and cannot seem to fix the problem for retrieving all my bookmarks and settings within the Firefox program! How do i restore all the settings i had?

when i launched firefox this morning, my profile was gone. I resynchronized, but it didn't load my profile. When I go to "about profile" none of the profiles offered matches mine. What should I do?

I mounted my windows disk and acces profile folder this is my windows 10 Profiles.ini content.

[Install308046B0AF4A39CB] Default=Profiles/4mltjd12.default

[Profile1] Name=Neutronized IsRelative=1 Path=Profiles/2lebgv8x.Prof1

Locked=1

[General] StartWithLastProfile=1 Version=2

When I go to my windows 10 and i open firefox i go to "about:support" and the profile im using is 4mltjd12.default So what i try is to move this profile to my ubuntu 18.04 firefox profile and load it

Windows 10 partition mounted in /mnt

from /mnt/Users/localhost/AppData/Roaming/Mozilla/Firefox$

sudo cp -r Profiles/4mltjd12.default /home/localhost/.mozilla/firefox/

and edited profiles.ini of ubuntu firefox to

[Install4F96D1932A9F858E] Default=4mltjd12.default

1. This is previous Default profile Default=4b9sltm5.default-release

Locked=1

[Profile1] Name=4mltjd12.default IsRelative=1 Path=4mltjd12.default Default=1

[Profile0] Name=default-release IsRelative=1 Path=4b9sltm5.default-release

[General] StartWithLastProfile=1 Version=2

But when trying to open firefox i get message: "Firefox already opened please close all firefox processes or restart" Am i doing something bad?

Hello, as in my title, all of my bookmarks from the last 10+ years have been deleted with this weird profiles update that happened. It told me to create a profile, I did, and then it took me to a browser that had none of my bookmarks or toolbar and had nothing in the backups at all. Am I completely screwed by the update or is there any way to restore?

I want to COMPLETELY wipe firefox, and then reinstall it and bring back only my passwords and bookmarks. I'm trying to troubleshoot some graphical glitches in firefox. How do I restore passwords and bookmarks after restoring? Thanks

I no longer have any:

passwords addons bookmarks history previously opened tabs user configuration

Nothing. Everything was completely wiped out. And that's just what I know about. Who knows what else is gone.

Does anyone know how I can retrieve this lost information.

Thank you.

I loose my hard disk so I reinstalled it (iOS Mojave) and all the apps, including Firefox. I had never saved explicitly my bookmarks so I do not have any html or other kinds of backup files. From the TimeMachine backup I have, I would like to get out my previous Firefox profile and put it in the right place on the new Mac. I found these instructions, that seem exactly what I need: "You can also copy Firefox’s bookmarks from its profile folder, if you cannot open Firefox on the old Mac or just have access to backups. Navigate to the “Library/Mozilla/Firefox/Profiles/” or “Library/Application Support/Firefox/Profiles” folders inside your user folder. You will find a folder named “Bookmarkbackups” inside a profile folder with a random name. Copy the most recent “.json” file from the folder to your external hard drive and use the “Restore” option in the Import and Backup menu to import it on the other Mac." But, unfortunately, both in my new Mac and in the TimeMachine backup the mentioned pathnames are missing. Under the "Library-Mozilla" folder there is only a file named global.regs. Under the "Library-Application Support" there isn't any "Firefox" folder, only a "Mozilla" folder containing another folder named "Extensions" (having 3 subfolders, all of them apparently empty) Someone can help me to find and replace my profile? Thank you!

I use FF since years and never created a profile. Hundreds of PW have been saved in the FF browser secured with my master PW. Since a few hours they are ALL GONE! I created the account I´m writing you herer from but obviously alos there no PW? What can I do. Need them urgently back.

Thanks for your help! Best, Karsten
