Firefox Community Forum

A popup box appears on screen when I try to turn on Firefox browser. I have never had to use a password before this box appeared. Funny thing is that when I click cancel the box disappears and Firefox comes to life. After searching I have found no way to remove this box and it is unnecessary. Would appreciate directions as how to remove this box.

Hello, For about two or three days now, when I launch Firefox and try to open any website, it takes maybe one minute to load the page, then the navigation is OK on every website.

It only happens when I launch Firefox for the first time of my session. If I close it then relaunch it, it's still very swift.

I tried clear cache and remove cookies, just lost my logins lol but didn't work. I also tried with no extensions, nothing changed. Lastly I tried to set "network.captive-portal-service.enabled" to "false" in "about:config" but it didn't change anything neither.

So before I try anything else that could erase something on my profile, I'd rather ask here for some help :)

PS: running FF 153.0.4 on Debian Trixie with Mozilla repos. Only have two extensions: µblockOrigin and NoScript.

Thank you in advance!

I recently bought a new computer and I need to know how to register this computer to my Firefox account,. and also remove my old computer from my account and keeping the same account number.

I've tried several times with different updates to use the AI-enhanced tab groups, and it has never given me actual useful suggestions of group names. It always shows me the most generic of names and chooses almost randomly what tabs to group. This is a thing that AI should be good for, but it looks like it's unaware of what is the content of my opened tabs.

Is this feature improving or I can disable it and stop it from consuming my CPU?

Recently I had to install a new windows, and I signed in to my Firefox account and found all the data from the previous windows including the open tabs, I could find them from "Tabs from other devices".

But now can't find them any more, although that device name is still there in my account page, under " connected services", please advise.

Hi, My Firefox crashes when alt tabbing into it from a 3D accelerated fullscreen application. Sometimes I am able to just close Firefox, most of the time the only thing helping is a complete system restart.

Hardware is an AMD Ryzen 5800X with a Radeon 6900xt and 32Gb of Ram. Windows 11 and the graphics drivers are up to date.

Firefox itself does not seem to recognize the crash and does not have any logs of it.

After I received a notification of a suspicious sign in from Brazil I attempted to change my password.

All went fine until after I received and entered the 6 digit OTC. When I clicked "Submit".... nothing. I tried to reset the password in a Private Window with the same lack of success. I can request the code, receive it via email, and enter it but am unable to submit it.

My account was accessed again from Jakarta and it now appears that the password was changed. On the Profile page it notes that the password was created 08/13/2026.

This is Firefox on Linux Mint 21.3

Whenever there's audio playing, such as in a Youtube video, there's also a faint continuous high pitched noise as well. This issue isn't present in other browsers, is there any way i could fix this?

"Please create a new version of the browser app that supports the ability to use FileSystemAPI on directories, this is essential for working with a BeatBuddy project and SD cards that are saved on my computer using the online editor."

Thanks

I've searched the community for support to add bookmarks inside my PDF files using Firefox, but all I get are articles and community posts from two or three years ago.

I currently see no features or buttons to edit the outline of a PDF using Firefox (153.0.4). Are there any Firefox extensions or other Firefox methods that I can use to do this in the meanwhile, or do I have to resort to using third-party software and solutions?

Where can I suggest to add this feature if it doesn't exist?

Thank you for reading.

Check https://piunikaweb.com/2026/08/14/firefox-x-images-videos-not-loading/ for details, but basically xTwitter/Melon messed again with their latest update.

Any word from those in the know yet? Having to use different browsers to see multi-pic posts is really annoying.

The plus sign to add a new window has disappeared. I search and went into Customize toolbar but there is no option to add the + sign back in. This happened previously and I was able to fix it. Now I can't. What is going on? what are you doing with firefox to make it so difficult to use. NOW I have to use chrome. I have been a loyal advocate for firefox for decades!
