Hi, i am trying to upload a Firefox extension, it is my first one and i am trying to upload it. I however cannot get it to work as the code my authentication app does not work. I have tried several authentication apps but i am always returned with the same error message whenever i enter in my code. "Invalid two-step authentication code". Is their a fix to this, so far i tried using google authenticator and DuoMoblile. Thanks

Sync works fine between my Android phone and my devices, in that I can see open tabs on the phone from both devices. But what does not work is sync between the laptop and desktop. They are both listed as connected devices along with the phone, both are signed in, both synch with the phone but neither will sync with the other, so I can't see the open tabs on either device. Is this an issue or is it by design? Thank you.

In May 2025 all browsers should have removed the default styling for the h1 element when it is nested in a sectioning element (article, aside, nav, section). I went into Firefox Dev Editions user-agent style sheet and noticed that the styling for nested h1 elements is still the same. I'm wondering why that is the case, since I was under the impression that all the major browsers had completed make the necessary adjustments at the end of May 2025.

Hi, an addon I was using was automatically disabled, with a banner containing the following text and a link to "see details": "This extension is restricted for violating Mozilla’s policies and has been disabled. You can enable it, but this may be risky."

This is vague and unhelpful, but maybe the "see details" link will provide more context.

If I click this link, I go to a new page which has the following: "This extension, theme, or plugin violates Mozilla's add-on policies. Version deleted"

This is even worse, as it's not clear what has happened, what I should do (if anything) and gives me no confidence in the process. Does "Version deleted" mean the developer deleted this, Mozilla deleted this, is it just this version or is it all versions? Why what it deleted, was there a security problem I should be concerned about, or does it no longer run on supported Firefox releases?

While I would be interested the reason for the specific addon, it seems to me there's a more important process and UX issue here.

Side note, there seems to be no topic for addons, which seems like an oversight.

My wife's Firefox was triggered from an e-mail link and in the process got updated to release 141.0 The result is that the tabs from the previous verion have not loaded. Can I still recover them?

I am old-school security conscious & have been using FF since its inception. Really. Clear my cache & delete browsing cookies on a regular basis. I use a private window for shopping and q&a info gathering. Recently I saw Walmart.com showing up in my cookies and couldn't figure out how/why as I *only* look at Walmart in a private window. Today I realized Walmart has managed to bypass the private window options and place cookies anyway! To say I'm furious about this is an understatement. I have adjusted my settings to "Strict" but it's still able to bypass the private window and is staying on my computer. I am updated to the most recent FF version; running MacOs Sonoma 14.7.7 which was just recently updated; I'm not going past this one for now but that really shouldn't be the issue. This is most definitely a FF issue and one that needs to be rectified not just because it's Walmart but because if they can do it so can others soon enough. This cannot stand.

Very often it happens to me that I'm not able to tell whether I'm at the beginning or at the end of a document. The scrollbar colors displayed by Firefox do not provide enough distinctive information to tell. (See images attached.)

From the 80's 'til the 10's we had 3D scrollbars with outset borders giving the impression of a raised scrollbar … for a reason.

Is there a setting to have Firefox display 3D scrollbars on Windows?

Hi: There is no Refresh Firefox tab. I go to Help More troubleshooting information. Like I've done a million times. And for Diagnose Issues there's only a Troubleshoot Mode and a Clear startup cache tab. No Refresh Firefox tab. I did not want a new profile. I did not want additional profiles. This has messed everything up. Firefox is not working. Thank you

Just noticed that Firefox only has translation for Chinese Simplified from Mainland China, but no Chinese Traditional from Hong Kong and Taiwan users. Any plans to get it going? I would hate to switch back to Chrome or Edge instead.
