If I go to the profile folder, exit firefox then copy and paste the folder to a backup location. The attempted backup fails. Something about permissions as I recall. I have tried many things unsuccessfully. Something has changed that does not allow for the backup of profile folders. Adding a backup option to the profile manager would be nice. I noticed some people have found work-arounds but I need a straight-forward procedure for backing up my folders. No work-arounds please, just a simple procedure. May I ask for help with this issue?

When I export a presentation from Perplexity in Firefox, the downloaded file is completely empty (slides without content).

If I do the same export in other browsers (for example, Chrome or Edge), the presentation exports correctly and the file is not empty.

So it seems this issue only happens in Firefox. Firefox 145.0.2

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.

Hello I got a pop up or it was new tab informing about new firefox functions. It was about profile creation and management. Now i have two profiles and cant switch back to my old one. I cant seem to be able to delete new profile to return to my old one.

Incoming messages on Firefox display is quite small as compared to Microsoft Edge and I cannot seem to enlarge as I do not see a "zoom" icon. When

I highlight the words, they are Arial font size 14 but visually they are not.  How do I zoom and default the window size? Here is a frame shot.

Dear Firefox Support,

Since yesterday, I’ve been experiencing an issue where the entire browser randomly freezes for a few seconds. When this happens, everything stops — I can’t open or close tabs or windows, and I can’t type in the address bar. If I’m typing something when it freezes, the input seems to be stored in the background and then appears all at once after about 5 seconds, when the browser becomes responsive again. All add-ons are disabled, the computer has been restarted, and the latest version of Firefox is installed. This issue started just yesterday — before that, everything was working perfectly. No new programs were installed, and all other applications on my system are functioning normally. When I switch to Chrome, there are no issues at all. Thank you for your help.

Best regards, Peter

I have two computers both with Windows 11 and Firefox is synced. On one computer the Capital One website works perfectly with no problems but on the other I can't get details of credit card charges and I often get messages like oops something went wrong. On that computer the site works perfectly when I use Chrome to access it. Any ideas?

Suite à la mise à jour de Firefox avec l'arrivée des nouveaux profils, j'ai perdu tout ce que j'avais enregistré sur ma session : tous mes mots de passe, mes marque-pages ainsi que les données de mon compte. Impossible de les retrouver ou de récupérer les données de mon compte initial. Je ne comprends pas ce qu'il s'est passé et surtout, j'aimerais savoir comment faire pour récupérer mes mots de passes et marques pages qui ont disparus ??

I had the Primary password set.

Today I restarted Firefox to install some updates (not sure if that's relevant), and when I opened Firefox again, I expected to enter my primary password for sync, but nothing showed up. I thought it was some bug after update or something, so I closed and reopened Firefox, but no dialog box came out.

So I went to passwords section and tried to view one password, which should prompt me to enter my primary password, but it just showed the password to me without asking for my primary. This is where I got quite scared.

I went to my settings and I found out that my primary password is just... not set. I did not remove it, I never told it to anyone, I didn't give anyone a chance to extract it. But it is just not there.

What the hell is going on? I couldn't find any answer to this, anywhere. Is there some option to see how/when was my primary password removed? Some logs?

I just purchase a new computer. Windows 11. When I first set it up I tried to log into Yahoo.com mail on 4 different browsers. None of them worked. Either had the error message of "1. Disable Ad Blockers 2. Enable Java Script". or "something went wrong". I disabled the ad/pop up blockers but cannot find settings for Java. I am not having trouble on any other device, nor with any other website.

I restored the computer to factory specs since I had hardly anything on it. That did not work either.

I want to delete/remove subject folder from my Windows 11 desktop. I did not create this folder; it suddenly appeared after I reinstalled the Firefox browser. These are the steps I am using in the deletion process: I right click on the folder and click on the delete icon. At the top of the window it says "Folder Access Denied." (Image 1) Below that it says, "You'll need to provide administrator permission to delete this folder." If I click on the "Continue" button, then the error message changes to "You require permission from OWNER/(me) ... to make changes to this folder." (Image 3) The permissions for this folder listed in the "Security" tab lists three groups: 1. "SYSTEM," 2. "F... S... (...@ Outlook.com)" and 3. "Administrators (Owners/Administrators)." All the foregoing have full control and modify control for this folder. The "More details" seen in Images 1 and 3 is grayed out so I cannot get any additional information. How can I delete this unnecessary and data hogging folder? Thank you all very much in advance to all that chose to respond.

I can't get to OpelGT.com. It is a car site that I moderate and visit frequently. I just get "waiting" or other messages if I use the link on the Firefox start screen. I can get to all other websites I normally visit with no problems(CNN, various Facebook groups and pages, Amazon, etc.). This problem started around the last few days of November. I CAN get to OpelGT.com using Microsoft Edge with no troubles.
