Firefox Community Forum

I have an website which I prior to this error message have visited many times on Firefox and had no problems. Recently though around two days ago I noticed that I couldn't get in and was met with the following message "Warning: Potential Security Risk Ahead". I can't bypass it apparently and I really need to be able to access this site as it's a University site.

I can access the site on other browsers such as Chrome and Edge but I use Firefox as my default browser and I'd like to keep it that way. I'd appreciate any help I can get.

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.

When I use Gemini 3 visual layout function to generate a homepage-like page, but Firefox cannot show any content of the result. It works fine in Microsoft Edge and Google Chrome.

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.

Firefox is preventing me from going to certain websites because it is telling me I am using adblocker but I have none installed.. I am trying to play around with the settings but I still can't do it. Is there an inbuilt adblocker? I need help please...

I downloaded firefox desktop for my imac 27" none of the passwords I had on file would work so I changed the password and tried it. It appeared to work but after a while the incorrect password came up again. I continued to try using the code you sent via email several times and even though it appeared to. accept the password it still rejects your code. I have tried both caps and lower case characters but it still rejects the login

Hi, I have 30 Firefox processes running and they are taking up ~2700 MB (84%) memory. I have 8GB installed memory. I'm running Win 11. What causes processes to run and how do I know which ones I can end?

Any help is appreciated.

Thanks, John

I have a new computer and I want to sync my Firefox account but the Sign In button next to Sync and save data options are missing from the browsers in both devices.

How do I fix this issue?

I just bought new PC and switched to win11(never happened on win10). Videos stutter when on 2nd monitor and game is open on first, but audio doesn't. Problem goes away immediately when clicking to the firefox window. Happens on both youtube and twitch, but not on Nebula.tv and not on chrome. Doesn't happen if the video is 480p, but does on 720 and 1080 and both of them are 60fps which might be something. Also doesn't happen if the game is windowed, but does on fullscreen and borderless.

I've disabled hardware acceleration (in windows and browser). I've tried setting both monitors to 60hz, setting firefox priority to high (and game to low), disabling effiency mode, setting power mode to performance and tried a lot of other things including about:config settings. Also ruled out extensions.
