Firefox Community Forum

I seem to keep getting a popup every few hours regarding XULRunner complaining about "This profile was last used with a newer version of this application. Please create a new profile." This will occur every so often, even when Firefox is not open.

I have already attempted to:

• Reboot
• Clear cache
• Uninstall extensions
• Uninstall/reinstall Firefox
• Downgrade Firefox
• Make a new profile and switch to it
• Delete all previous existing profiles

I think I've run out of things to do, anyone got a silver bullet for this thing? I was unable to find anything conclusive with Google, so I figured I'd ask here.

If I try to type the URL for Wikipedia in the URL field, Firefox suggests Wikihow. How can I change it so that it assumes I want Wikipedia?

(Using Firefox 134.0.2 on MacOS 15.3 (Sequoia).

One specific site used to work very well. Suddenly it stopped, showing the continuous running circle. It works on another device. Obviously some setting on this device has changed, but I didn't change anything myself. Please help.

Hi, I have noticed that recently the URL link in the posts, and the video in the post are not displayed when using X (formerly Twitter). Initially I thought my security software blocked the contents, but I do not have such issues when used another web browser on the same PC, or the app on my Android.

Could you please let me know how to fix these? I have a lot of bookmarks and passwords saved, so I do not want to lose them.

Thank you for your help in advance!

My Firefox suddenly seems to be behaving abdurptly. The icon of the taskbar for firefox is also lost, and it was hard to open. I just updated my windows and I observe this effect. What oculd have gone wrong? What data would you need to get to root cause of this?

bold text Rufe ich firefox auf, ist der Hintergrund weiss, sobald aber eine Seite aufgerufen wird, ist der Hintergrund schwarz Alle Versuche über add-ons etc/ Einstellungen ändern bislang frustran

Das ganze ist, seit ich bei eingeschaltetem PC mit einem Staubtusch über die Tastatur gefahren bin

I have used Firefox for years, and especially since the ability to pin tabs was created. After this last update I experienced an issue on one website, which the tab is pinned, that was not present before. After putting things into my shopping cart, I click on the shopping cart and if the original tab is pinned then the shopping cart opens in a new tab. Before this latest update Firefox was smarter than that.

a few months ago firefox started rendering images funky. I am not sure what changed, it seems to be a setting problem as other computers with FF 135 don't seem to do this. I have not been able to come up with the right search terms to describe the problem. here is a screen shot of the issue.

Hi,

We are using Mozilla's URL (https://firefox.settings.services.mozilla.com/v1/buckets/blocklists/collections/certificates/records) to fetch the OneCRL.json that contain the list of CRL data. This URL was working fine till recently (last month) and we see this URL is returning 404 error. Attached the screenshot of the error.

Need some help on this. Is this a temporary issue OR Can we use different Mozilla URL to get the OneCRL.json data ?

Appreciate any assistance on this.

Thanks, Bharath

Hello,

I inadvertently used the option Block Element to get rid of a horrible recurring spam post on FB. I thought I was just blocking that post but what it ended up blocking the options on my whole Facebook program, so now I can't edit/undo anything on my FB page. I know it's within Firefox as it doesn't happen on the other browsers when I am using FB.

I tried to look it up but can't find anything to help me. I was hoping I could end up talking to a real person as I know it can get confusing but perhaps you can give me step by step instructions?

I need to know how to UNDO blocking an element. I've attached an image but I'm not sure if it fully explains what I'm dealing with.

Thanks, Ellen Claxton
