Firefox Support Forum

my version of firefox is obsolete in security...so as many sites tell me. I want to upgrade to the newest release but am not sure what happens to my stored logins and passwords. Also, is there any way I can view the stored info...since I have been careless and not saved all of that info.

I recently purchased a dell refurbished computer, I set it up went and downloaded fire fox without any trouble. I restarted computer today and it would not accept password I called DiscountcomputerDepot.com help and they helped me to restart and they told me they would have to reinstall windows from computer. So I lost all my programs. when it restarted said would have to update windows. I have tried multiple locations and get this same message This download.mozilla.org page can’t be foundNo webpage was found for the web address: https://download.mozilla.org/?product=firefox-stub&os=win&lang=en-US&attribution_code=c291cmNlPShub3Qgc2V0KSZtZWRpdW09KGRpcmVjdCkmY2FtcGFpZ249KG5vdCBzZXQpJmNvbnRlbnQ9KG5vdCBzZXQpJmV4cGVyaW1lbnQ9KG5vdCBzZXQpJnZhcmlhdGlvbj0obm90IHNldCkmdWE9ZWRnZSZ2aXNpdF9pZD0obm90IHNldCk.&attribution_sig=c3e7484d24556be08270fa603b3ed24cad53bd6caaec3f9e3f355d5c37300daa HTTP ERROR 404 Please help ,I have only use firefox since I had a computer , about 25 years.

At some point every night, my Firefox (and only Firefox) reverts to version 111 from the latest version. This happens on 2 different Windows 11 machines.

I can only get Firefox to run again by running from command prompt with "-allow-downgrade" option and then updating again.

I usually don't notice until I launch Firefox the following morning and it gives me a message that the profile was created with an older version and to exit or create a new profile.

I've had Firefox open and then it reverts and it gives me a XULRunner error about the profile being used by an older version.

I don't have any special backup or restore software running and the physical files in my Firefox folder in c:\program files\mozilla firefox are being physically pushed to a prior version dated 3/21/2023.

On both machines, I've completely uninstalled and reinstalled and it's good for a day and then reverts.

No log entries for the reversion can be found. It's just back to a prior version.

I've never come across anything like this before and have scanned for any malware or other issue, but haven't found anything.

Trying to download nord vpn and is says "failed" tried to download a receipt for the purchase of above and it says "failed" the browser on Win 10 is set to save files to downloads

When I try to open any PDF file, I have to Browse to find my pdf viewer (Flexipdf). I do that and also check your "Save this for future" option. Every time I try to open a pdf after that I still have to go through all the Browse steps. I also set up Flexipdf in your Settings and it just gets ignored.

Hello Fred McD,

Thanks for getting back to me. First, my computer screen froze (I suspect some interference of a hacker or something).

Anyway, I turned off my computer, waited several minutes, and turned it back on, again. A message came on the screen said I wasn't "signed in." Then, another smaller window came up saying I could "sign in" by clicking on a blue button. But, that didn't work after three tries, so I clicked on the "closed" button. That allowed me very limited access to the internet. A "black" label announcement said that I wasn't signed in - and that my files were inaccessible to me.

It looks like I need a technician, but I presently have no car and I don't know of any technicians who do "House Calls."

I'm also wary of contacting an online technician. One time a year or so ago, I looked up a phone number for Microsoft - and the guy I spoke with had an "Indian" accent. He sort of helped me for a stiff fee. In hindsight, I realized he couldn't possibly have worked for Microsoft - even though he assured me that he did...

Can you or someone on your staff possibly help me. I trust Mozilla Firefox and I'm prepared to pay a reasonable fee.

Thank You, Eric Vollmer

My laptop died but I have been able to rescue the SSD and turn it into a USB connected external drive. I can see all data from my old PC.

I have tried to copy all of my User, Local Apps Data Mozilla Profile data folders to my new Laptop but the data does not appear when I fire up Firefox on the new laptop.

The old laptop folder was c:\Users|Phil, the new laptop is C:\Users\Phill {setup of new PC added a second L to my name}

Is this an issue ?

On one computer I have deleted everything from Firefox including the folders within Apps Roaming except for one folder. There in one folder "41A66E7EE5E1" within Profiles which I cannot delete. It holds the files prefs.js and sessionCheckpoints.json which were created at 20/02/2021 and I cannot delete those.

My new installation is dated 24/07/2021.

There is nothing in the properties of those two files to suggest an issue. I do find however that when I seek to change the Property/Security to Administrator (I should be able to do that) I receive a dialog box that "the file or directory is corrupted and unreadable".

Please advise on how I address this.
