Firefox Support Forum

as of 2023/09/29 hulu, netflix, prime and disney+ are not playing videos on firefox, after making zero changes to settings or configuration.

I tested Netflix on Google Chrome and videos played, confirming this is a Firefox issue. I cleared recent/all history and changed passwords for those sites. Netflix logs me out if I attempt to play content. Speedtest reports 200 mb/s. Mozilla VPN is installed but turned off. Netflix sign in reports a new device/login in my state which is different from the VPN setting so this confirms that the VPN is not active and blocking content. HBO/Max videos play correctly and that site does not have the same issues. Firefox has crashed numerous times in the last two weeks. Sometimes just a single tab, sometimes a full application insta-quit.

I prefer to compartmentalize usage across different browsers for privacy/security reasons and would like to continue to use Firefox for these streaming services.

I was set up, in myuserchrome.css, to hide my pinned tabs on the tab bar, allowing them to still be available in the "List all tabs" menu, see first image

.tabbrowser-tab[pinned="true"] { display: none !important;}

All of a sudden, it reverted back

That first image, with the hidden tabs, is actually from Librewolf, with has the identical setting.

One version says go "Tools > Options > Content" - but my Tools mention has no options found

Other version says to " Enable JavaScript on Mozilla Firefox

   1. On the web browser, click the Firefox menu and select Options.
   2. In Options window, select the Content tab.
   3. Mark the Enable JavaScript checkbox.
   4. In Options window, click on the OK button to close it.
   5. Click on the Reload current page button on the web browser to refresh the page.

Again, not found

I am in IOS Firefox, 118.0

Per version 118 we now have the possibility to have webpages to be automatically translated from its original language to another one. As end user I get prompted for every page I visit whether I would like that to be translated. This is quite the flow-stopper. I have no need nor interest for this amazing functionality. However, I can't find anywhere an explanation on how to disable that functionality. I would appreciate it if I was not prompted for this translation possibillty. My question: how to disable this translation functionality alltogether? (I.e. How to stop Firefox asking me about it?)

After upgrade to Firefox ESR 115.3, receive pop-ups of "Alert - Please authenticate to the token "ActivID ActiveClient 1". How to do so depends on the token (for example, using a fingerprint reader or entering a code with a keypad)." Firefox ESR 115.3 is installed on Windows 10 (22H2). ActiveClient 7.1.0 is used with SCR33x USB Smart Card Reader and US Government issued CAC (Smartcard) for authentication to different web sites. Some authentication actions complete by merely clicking OK on the pop-up alert. However, at least one web site (a tenable.sc site using authentication integrated with Active Directory) fails to authenticate and displays a Sign In requesting Username and Password. The only way to complete login (passwords are not permitted and smartcard authentication is required): In Privacy & Security > Certificate Manager > Authentications Decisions + delete the listing of the host name for the tenable.sc server. Close Firefox browser. Open Firefox browser and select the tenable.sc web site (it is an internal URL). Acknowledge the pop-up. A dialog box is displayed to select the certificate from the Smartcard. Authentication is successful and site is usable for that session; however, after browser is closed, inability to authenticate with SmartCard with future sessions unless the host name is deleted from the the Authentication Decisions. The SmartCard Reader is loaded in Privacy & Security Device Manager as ActivCard7.1 using the acpkcs211.dll from HID Global. Prior to upgrade to Firefox ESR 115.3 (from ESR 102.15); the pop-up did not appear for any of the CAC enabled web sites and login to the tenable.sc server correctly used to the smartcard certificate without requiring deletion of the hostname from authentication decisions.

Is there a main location where Firefox extensions (like Forecastfox) keep their settings? If so, or if you happen to know where Forecastfox in particular keeps its settings, I could use some help locating this folder. I have a settings file I could put in there to overcome some difficulties that the folks at Mozillazine can't seem to help with. (https://forums.mozillazine.org/viewtopic.php?f=48&t=2913287&p=14963740#p14963740). The folder I have is named Forecastfox.2023.04.22.21.11.51.txt

Over the last year I have uninstalled FF removed settings then reinstalled from scratch. Its been over a year now and FF never can pin point where I am at. Today it says I am 1300+ miles from where I am. I really don't want to go back to using Chrome but it appears I will have to as it normally has my exact position. I travel for 6 months of the year and have 3 internet connections shared via an internal WiFi that I use 99% of the time. They are connected via Starlink, GoogleFi (T-Mobile) and AT&T SIMs. I have a SSID with the _nomap suffix and that fixes Chrome but FF NEVER seems to know where I am, no matter how many times I clear the browsing data. I really don't want to go back to Chrome, but I cannot do my work if FF thinks I am somewhere else all the time. Geez, If only there was an addon or extension that would override FF location so I could tell it where I am. I'm in FF Hell. -Bill

I can not access for days my bank account at truist.com. It shows it is loading but never does. I CAN access from any other browser want to use! Truist says it is a Firefox browser issue.

On my work laptop, I disabled "Recommended by Pocket" to avoid distractions.

On my personal laptop, that setting is already enabled. But I never see any stories recommended by pocket when I open a new tab. What can I do about this?

Can't update to latest version, or access any Mozilla site. Instead I get an Unable to Connect -- try again message. No other websites affected, just Mozilla. Tried running Firefox in recovery mode, same result. Also tried to download an installation package using Chrome. Again, the same error. I'm asking for help on my phone, since doing so on my laptop is denied. Would appreciate assistance.

Centurylink Webmail will not open in Firefox. Worked yesterday but not today. Can open it on Chrome, Edge, and surprisingly a "Private" Firefox window.

I've made no changes to browsers in the past week so don't believe it is anything I did.

Help, please. Not sure what to try next.

Hola. Mi ordenador tiene Debian 12. Utilizo Firefox 118, instalado a través de Flatpak. El problema que tengo en algunas páginas es que veo las fuentes pixeladas y la impresión es muy defectuosa, hasta el punto de no entender lo que aparece escrito. Esto sólo pasa en algunas páginas.

Si descargo directamente Firefox desde la página de Mozilla y abro la paǵina con una configuración limpia del navegador, las fuentes se ven correctamente; sin embargo, si sincronizo los datos de usuario, instalándose los datos, extensiones y demás las fuentes en determinadas páginas se ven mal.

Desactivé las extensiones pero el problema no se resuelve. Desde una instalación limpia de Firefox instalé una a una las extensiones y complementos, pero no logré reproducir el problema. Borré incluso la caché del navegador, pero nada. Y también sincronicé los datos de usuario en una instalación de Firefox en Fedora, pero el resultado es también negativo.

Alguna idea?

Gracias.

I have been using the Walgreens web site to manage my many prescriptions without problems. Now, most of the Walgreens web site still works but the two menu options that need to display my personal prescription details fail with the display "Sorry, an unexpected error occurred. Please try again later." I initially thought that a Walgreens update might be in progress so just waited. Walgreens support gave me the same answer that there was probably web site maintenance in progress. After 4 days of the same problem and answer, I ported enough information to login in to Walgreens with the Microsoft Edge browser and access to my prescription information worked without a problem. I believe this problem with Firefox started around the time I updated to 117.0.1 but I might not have this perfectly correct. I was just notified to update to 118.0 and did so. Firefox access still fails and Edge access still works. Thanks for any help you can provide. Windows 10

Is there a way to stop Firefox from creating a desktop shortcut every time it updates? It is just desktop clutter for a lot of people, especially since Firefox is pinned to the taskbar anyhow.

I use 50+ Add-Ons on Firefox. I would like see all the Add-Ons I gave permission to work in Private Mode, all in one page. Is there a Settings page that shows all Add-On permissions to shown in one place?

So far I've been clicking on each Add-On, one by one. It becomes very tedious to manage them when you have no other choice.

Thanks, Cheers!

I am using Firefox 115.3 on Debian 12.1. I have numerous tasks which require the use of my web browser and have allocated a different virtual desktop for each. This means that my browser session typically has several dozen tabs open in numerous windows at one time. Under normal circumstances, this works just fine (and is a testament to the engineering that has gone into this browser).

My issue is that Firefox renders my machine virtually unusable for a few minutes each time I restart my desktop session due to focus stealing. When I open the browser, several dozen windows pop up (as expected) and relocate to their correct virtual desktops (as expected); however, as the windows begin to load, the most recently active Firefox window steals focus repeatedly. If I am, for instance, in the process of typing my password into my desktop e-mail client, a Firefox window may steal focus from the password dialog. In practice, this focus steal happens once every few seconds for several minutes.

I would prefer that Firefox would not steal focus while restoring a session. Does anyone have any suggestions for correcting this issue?

Your new translation feature is great, by any chance do you have simplified Chinese or will that be coming in the future? A second question, what is your pricing for VPN? Thank you for your time.
