Firefox コミュニティフォーラム

Hello,

Not sure if posted under the right section.

Recently started having an issue trying to sign in to Microsoft Outlook (formally Hotmail) Web. I don't recall any changes i made or updates.

When i try to sign in, it opens a new tab and takes me back to the sign in page. This just continues.

Tried using MS Edge and don't have the issue.

So far tried Safe Mode which disabled add-ons, which are currently Add Block plus, and New Tab Override and the issue remains. Not sure if i tried the refresh option but i think it removes the extensions which is not the end of the world.

Added a few images, one shows duplicate tabs, which will continue

Firefox version 140.0.4 (64-bit)

Any ideas whats going

Thanks

From a week ago, for no apparent reason, I get "403 Forbidden" when I try to read articles on seattletimes.com using my prescription to the site. It's a total block of the site.

After rebooting, the site is OK until I log in, as needed to read particular articles. Then nothing is accessible any more.

The trouble is the same on all my laptop/desktop computors, which all have Firefox and are in sync with it, and once I log into the site on one of them it's blocked on all. But this doesn't affect my android phone, on which every article can still be read.

This is clearlly therefore a Firefox problem.  I'm worried that I'll have to switch out of Firefox to some other browser.  This is unreliable behavior.

I usually use Nightly as my default browser in a Windows 11 system. Recently I started to get a new error message showing up when I try to select multiple messages in Yahoo e-mail. I select them by clicking on the first message, then holding down Shift and clicking on the last message in the range. That should turn on the selection boxes for all the messages between the two.

Now, when I press the Shift key, I get an error box right on top of where my mouse cursor is, so it interferes with me. The top of the box says "mail.yahoo.com", which is the web-site I'm signed in on. Then it has a link with the text "Login - Sign in to Yahoo". Below that is an ad for all the wonderful things I can get by signing in to Yahoo. At the bottom is an error message, "We can't generate key points for this webpage."

I tried the same action in the current General Release of Firefox, v140, and this does not happen. I suspect that this is an intrusion by some sort of AI software, but I don't know what setting might have been activated to turn this on. Does anyone have any idea how to turn it off?

Lately when composing an e-mail at gmail.com on my Firefox the attachment button is missing. As well all styling aids are missing (font, fontsize, bold... etc.). This problem does not arise, when using Chrome or Windows Edge instead Firefox. But I sure want to stay with Firefox.

Firefox version 140.4.0 Windows 11

Thank you

I'm trying to access my federal government account. They want me to verify my identity at verify.id.me. When I reach the point that it wants to see my ugly mug on camera it tells me there is no camera. I've given verify.id.me permission to use the camera in privacy & security. I can record a video with ffmpeg. What have I missed? I don't see any relevant errors in firefox's output. I'm trying in safe mode.

When use the built-in button on a video to fullscreen it (Youtube or any other site) then the taskbar will do the animation to go away then instantly come back up. If I use f11 I to fullscreen all of firefox the taskbar does not show. Why is this happening with videos? Using other browsers I do not encounter this issue.

Trying to sign in on AOL and getting error number 15, this is Mac pro book and FireFox browser, went to Safari everything worked on that site. Went to my Dell Desk top with FireFox and it worked ok that computer. Has anyone else had this problem.

I tried to log in to NextDoor, which was supposed to send by email a 6-digit login code for me to enter. I tried at least twice, and no code was received. I'm using Firefox 128.12.0esr on a Mac running Catalina 10.15.7. Logging in to NextDoor from a Brave browser worked just fine, including getting the code by email. How to I fix this?

I have been having a problem the last 2 weeks. When ob certain pages my browser will suddenly jump to the top, or near the top, of the page. I have mostly noticed it on Walmart when i try to click on the add button or if i remove an item from my cart. It happens on a few other places like Barns and Nobles . Anyone else having this problem? Cant be sure but i first noticed it after one of the last updates. I have tried running my browser in safe mode and disabled all extensions and add-ons but still does the same thing. click and and page jumps to top. click on an item to look at it and the page goes all the way to the bottom.

Hi,

PayPal has a new verification method that involves sliding a bar.

After doing so it says I've been blocked.

I can log in using Edge (but I don't want to have to use Edge for PayPal).

Any help is appreciated.

Picture verification is Not working in Firefox, works correctly in Chrome. This is the verification I have do at some sites to make sure it is me or that I am human after I have not been on a site for long while.

It keeps repeating the picture even though I select all proper pictures. It happens to all sites I visit.

Firefox 139.0.4. version is also not good! Uploading videos to Youtube does not work with it! It does not move from zero percent! As I wrote earlier, the problem started with version 138.0.4. and is still ongoing! Uploading videos works with other browsers! I am waiting for the problem to be solved! If I wrote my letter in the wrong place, please forward it to the authorities! At the moment I could write a letter here, I can't really find a topic where this would be discussed! My OS Win10 64 bit. Thank you!

Hi everyone,

We’re testing scroll-linked animations on a landing page built with Tailwind and custom JS for our client project hosted at https://noveltyads.com. Specifically, we’re exploring the ViewTimeline API and CSS animation-timeline for a horizontal scroll section.

While everything works smoothly in Chromium-based browsers, we’ve noticed Firefox behaves inconsistently in the following ways:

The animation-timeline: view() property doesn’t always trigger on scroll as expected.

Debugging with Firefox DevTools, the animations don’t appear in the Animation panel at all.

We confirmed that no polyfills or fallbacks are interfering.

This is happening on a custom-built section on this live test page: https://noveltyads.com (it’s a mock client version for internal QA — nothing behind a paywall or login).

Has anyone experienced similar behavior with Firefox’s scroll-driven animations or ViewTimeline implementation?

We’d love to know:

Whether Firefox fully supports ViewTimeline (or still considers it experimental)

Any DevTools flags or settings needed to see scroll animations properly

If there's a better way to ensure cross-browser consistency using native APIs

Thanks a lot for your help and insights!

I am not having trouble signing into any page except FaceBook, I just get a plain white page. I am able to sign in on my phone and a secure browser, but FireFox in my default browser.
