My computer updated with no warning one night, and i lost all personalization and even everything stored in my firefox, the sign ins, passwords, bookmarks, all. is there a way for me to find all that was erased?

I did an Upgrade to a version of Firefox that would bypass those "Your Browser Is Not Supported" messages that apparently come from "Cloud-flare." I figured [naievely!] that my addons would "port" to the upgrade. They didn't. Is there any way [e.g., a putative backup file, perhaps] that would allow this?

Thanks in advance...!

While following this step in order to reduce CPU and memory consumption of firefox [content-prefs.sqlite file], I accidently deleted the Profile folder itself.

After this firefox wasn't opening and was stuck on not responding in activity monitor.

I reinstalled firefox, multiple times even after a shutdown, removing any old files in the Library folder. Still it's stuck on the same issue, firefox doesn't opens up even once.

This has been going on for over a week. I have downloaded and applied the installation program multiple times (>3). The problem persists. What is going on, and how do I fix it? Thanks

So, I installed a new hard drive about a week ago and while re-installing things I also re-installed the Firefox Browser 64- bit. Strangely, it seems like the files did not install itself in the right areas or the files installed did not install themself in the right or normal places. It does work, but for some reason I don't see it's program files? Is this normal or something that happens?

Anyways, I've backed-up my bookmarks, and I am going to uninstall it, re-boot, and re-install it and see what happens I guess. Or should I uninstall Firefox and its Profile Folders also, etc, and than re-install it?

All of a sudden, I can't download any attachments, no matter what file type it is. I've reset Firefox to it's default, restarted, everything suggested. I don't have the first clue as to what this is.

After installing Thunderbird i had first download problems for new Firefox Versions. I tested around, installed everything new and found the solution. Somehow the Maintenance Service didn`t work properly on my machine and after deinstalling and restarting i can update firefox again. Problem remains: When trying to install Offline Languages , see picture, i get the message that it does not work. I tried everything possible, including reinstalling and deleting all old profiles (was a lot of work). Any ideas?

I use Using Video Download Ultimate add on in Firefox. It works great on most websites, but it will not connect and download from "https://yeahmovies.to/home" or "https://ww5.cmovies.co/movies/". Will you rectify this, or teach a work around to me?

Many thanks. Roger Woods buckwoods@yahoo.com

Hi there. I love Firefox, but I have an issue at the moment where I have one copy set up on my Mac, and it has two profiles. However, I'm running into regular problems where they're both open and they can't quit, or they crash, or they want updates, the other one, and then it has to be restarted and can't open web pages for stuff like that.

A little bit more about my setup. I have two admin accounts on my Mac and an applications folder with Firefox in it. Then each of my Mac accounts has a version of Firefox with a different profile.

I'm about to do a clean install of macOS with the two admin accounts. I want to install Firefox correctly this time. How do I have two entirely separate copies of Firefox running on my Mac in the two admin accounts? I just don't want their threads to be mixed or them to be updating each other or anything like that.

Absolutely love Firefox, but this has been quite a big issue for me and I'd love some advice here. Thank you.

Additional note, I followed the link below the first time I setup to create two profiles, but that didn't quite do what I wanted.

A firefox support article told me to reinstall firefox from snap on ubuntu, without mentioning anything about the profile, settings, and bookmarks. Now everything is gone.

Is there any way to recover my local profile?

I don't think it was synced properly with my other devices

Hi,

My computer was on during the week-end and when I came back home I noticed we had a couple of power outages. Computer restarted automatically (Win 10 22h2) and when I launched Firefox, it started as brand new with all my addons gone and none of the previous session restored (I had 4 Firefox browsers opened with each 20+ tabs opened).

I have tried looking at C:\Users\MYUSER\AppData\Roaming\Mozilla\Firefox\Profiles but found nothing of interest. Where is everything and how can I restore everything I had ?

I even tried Troubleshooting mode and downgrading to a former version of Firefox (126.0.1 64 bits).

Thanks,

Hi when i have to download my bios updates i am being forced to use misrosoft edge or chrome none of which i use , so the question is can i use firefox safely thanks . Lee
