Greetings everyone,

Earlier, when I opened Firefox it didn't restore the tabs and windows I had been using from about 2 weeks ago. I tried looking in "History" in the Firefox menu but it only displays tabs and windows that I've closed and it doesn't have the tabs and windows I had actually open.

I've had the same Firefox settings since I first installed Firefox a few years ago and this is the first time this has happened... :'( :'( :'(

I must have had about 70 Firefox windows and even more tabs within those windows so this really hurt me... :'( :'( :'(

Thank you for any help!

What happened to Firefox's permission's page? There's so few options now. I'm being harassed by websites to give them permission that should be blocked across the entire browser. I'm autistic and sensitive to popups/interruptions/distractions. So most permissions I simply had off for everything, because I don't want to be asked anything. I don't want to confirm anything. I don't want any popup of any type. So I turned everything off and it was good. (except blocking cookies of course)

But now sites are asking me again and there's no way to blanket turn off everything. I see I can press "Ctrl+i" to bring up specific permissions for that site, but that's not good enough. I specifically need permissions blocked for sites I've never visited. Needing to visit the site first completely defeats the purpose.

The permissions listed in the settings isn't all of them. How do I turn off ALL permissions for ALL sites. I can turn on specific permissions when I want them. Essentially, how do I recreate functionality that used to exist but was removed from us for whatever reason.

Also, it's a huge security hole! I'm a senior full stack developer. Asking permissions for a user is a great way to fingerprint them. If I accidentally hit "yes" to a few key permissions, I can be fingerprinted. Another reason I should be able to blanket ban these permissions. I just want my browser to be a browser. These permissions do nothing for me but make the experience worse.

As the title says. I get this prompt on videos from different, yet particular websites and sources. And they fail to load. It's also happened where some video's work and some don't, side-by-side on the same website and session.

  • I've tried clearing all of my cached data, my browser history, cookies, site-data, settings, and fill-out information. No avail.
  • I've tried disabling all of my extensions and add-ons.
  • I've even tried using google instead, but I just get constant loading on those particular video's with no thumbnail (As depicted in second picture).
  • I've checked my video drivers for updates.
  • I've tried reinstalling Adobe Flash Player, even though it says it's no longer supported.

Since it also might be happening in another browser. I understand how this might not be Firefox's fault. But I'm hoping you'll be able to help me still.

I’ve been using Firefox with a screen reader, and while it works for most basic browsing, I’ve noticed some issues with certain sites. For example, form fields aren’t always announced properly, and sometimes navigation landmarks are skipped. When I test the same pages in Chrome, the experience feels smoother.

I’d like to keep using Firefox, so I’m wondering — is there something I can adjust in my settings to improve screen reader support? Or is this more of a compatibility issue that needs to be reported as a bug?

If others here use screen readers with Firefox, I’d love to know what has worked for you. Are there specific add-ons, preferences, or troubleshooting steps that make accessibility better?

Thanks in advance for any guidance.

Dear Mozilla Support Team,

I am writing to report an issue I have consistently encountered while using the Firefox browser. Whenever I log into my Mozilla account, the custom theme I have selected for Firefox is reset to the default theme. This necessitates manually re-selecting my preferred theme each time I log in.

This issue is a minor inconvenience, but it disrupts my user experience. I would appreciate it if you could investigate this behavior. I am using the latest version of Firefox on Windows 11 Pro.

Thank you for your time and attention to this matter. I look forward to a resolution.

Sincerely,

Clóvis Lauriano [edited email from public]

Hola, por favor, necesito ayuda con el micrófono. Como pueden ver en la imagen adjunta, cuando intento dictar por voz, aparece que el micrófono está deshabilitado.

He intentado acceder a los ajustes, pero no sé cómo agregar la página de Google Translate (u otra) a los permisos, ya que no encuentro ninguna opción que me permita incluir manualmente una nueva URL para habilitar el micrófono. Tampoco aparece la opción para permitir el uso automático del micrófono.

Además, he notado que ahora hay una nueva ventanita a la izquierda del chat de ChatGPT (¡me gusta mucho esta función!), pero el micrófono tampoco funciona en esa sección.

Agradezco mucho si me pueden orientar para solucionar esto.

Tab groups & bookmark favicon syncing issues

Hi, I've been using the latest Firefox version on 2 MacBook Pros, and the bookmark favicons are lost when syncing to other devices. They remain on the host device, but are not transferred to the synced device. This is my first attempt at syncing anything in Firefox, so I don’t have any previous settings/files that could be interfering.

Also, “Tabs from other devices” in the Firefox View window lists all of the tabs grouped together, and there are hundreds in the list. How can they be grouped by window (the same way that they appear in the browser), and is there a way to have them sync directly in the windows (w/ fwd/back history in tact) so that each browser appears identically when switching from one device to another?

Thanks

Every time I login on my computer, there is already an open Firefox webpage with a dialog box asking me if I want Firefox to be my primary default browser. Once I click "Set a Default Browse", a Microsoft Edge webpage appears giving me a list of choices of Microsoft application to select to be my browser. Firefox is not on the list. There is also a dialog box that appears on the lower right corner of the screen showing me the steps on how to make Firefox my default browser. The choices are "Show Me How" and "No Thanks". When I click the "Show me how", I am taken to Firefox setting, once I click the "Make Default" I am taken back to the list of Microsoft applications to choose as my browser. The bottom line is I cannot make Firefox my default browser anymore. In fact, I am not even sure if I am sending this message to Firefox or Mozilla. This is the URL that I see on this https://support.mozilla.org/en-US/questions/new/firefox/form.

Would you please check and correct the problem. I cannot make Firefox my default browser. Would you check if Firefox is my default browser.

Firefox claims does NOT save site/URL visit information while in Private Mode. And I thought that was true. However, I just discovered that Firefox DOES SAVE Private Mode URL/Site visits - in this specific place. I don't know how long the history will be saved - it looks like at least as long as the Window is open. I want to keep most of my open Private Tabs open - but want to Delete/Clear the ones I'm done with. I thought/understood that Private window/tab/visit info was not tracked/saved - and it's not saved in History, or Searchable. But it appears that this doesn't apply to the Recently Closed Tabs MenuItem. And there seems to be NO 'delete' or 'clear' option for this field. I can't find any reference to the subject in the Forum or Articles. The picture I've attached is NOT of the Recently Closed Tabs while in Private Browsing, but is the same MenuItem and field contents. Thanks for your interest. I'm hoping someone can help me figure out how to delete/clear this specific history.
