Firefox Support Forum

Hi, the turbotax website forced me to update Firefox and since I did, I am no longer able to open the browser at all. The error message reads, "You can't use this version of the application "Firefox" with this version of OS X. You have OS X 10.11.6. The application requires OS X 10.12 or later." Unfortunately, from what I have read, I can't get that update that on my iMac (21.5inch, late 2009) OS X El Capitan Version 10.11.6. Is there any way to downgrade the Firefox install? I can't even see what previous version of Firefox I had before because I can't open the browser anymore. If anyone can help I would be super grateful. Thanks in advance!

After Firefox updated to v127 YouTube videos stopped working for me. They work fine on Microsoft Edge and Google Chrome. Considering this only started happening with the latest update and the fact that YouTube videos work fine on other browsers the problem I feel has to be somewhere in Firefox. When I try to play a video I get the white circle going around in the center of the screen and the video does not play.

When I try to view my pictures... Firefox has started to ask, every time... "how do I want to view this JPG file.

I must choose, Firefox, Internet explorer and so forth. I choose Firefox and it opens.

BUT.....

How do I get this message to STOP.... every blasted time I click on my pictures.

There's some stuff in the "about:config" that someone changed from true to false... I think...

What do I change back... so this annoying pop up.... stops....

When using Firefox to access Hulu Hulu does not accept my password though it does let me reset my password. I CAN access Hulu using DuckDuckGo and IE. Have not been able to get through to Hulu.

My email address is [edited] @emal.com....you do not have this for me so I do not get any emails due to this error. You can call me at [removed phone# from public support forum]

To whom it may concern, Hi, I haven't been able to access this website for a couple of weeks and have never had any problems opening it in the past. Have contacted the bus company and they do not have any issues at their end. This is the error message I still continue to receive and don't know how to correct:

Unable to connect An error occurred during a connection to www.premierillawarra.com.au. • The site could be temporarily unavailable or too busy. Try again in a few moments. • If you are unable to load any pages, check your computer’s network connection. • If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

Hope to hear from you soon

I have used Firefox to access my Zoom accoutnfor several years. Today, the screen goes blank when I click on sign-in. This does not happen with other browsers on my PC. Help....

Hi Mozilla - I just wanted to report some recent phenomena. In the past couple weeks Firefox, and related Private Browsing browser, seem to have developed consistent hangups in fetching data across a pretty wide range of sites. Both my banking sites will not load after logging in to them, just spins and spins. Also some very general searches will not load any results for minutes at a time, I just give up and kill them. I've uninstalled/cleaned/reinstalled latest version, etc, etc. By comparison, these same data fetches in banking sites, etc, work dandy in Duckduckgo browser, which is also a heavy no-trace browser. This ominous to me as I really like Firefox and do NOT want to have to resort to Edge. Duckduckgo browser is very good but doesn't have nearly the menu or favorites sort of features that Firefox does. Can you investigate? This is typical Win 10 system in Lenovo i7, been working like a champ till just recently, no system changes. Thanks.

I using an ASIS Latop model X756U running the Windows 10 Operating System. Firefox is my default browser.

I installed the Opt-Out Google Analytics Extension on 9 June 2024. The intent was identify which of my applications are using Google Analytics by testing them and seeing which ones were broken.

Having done that I removed the Opt-Out Google Analytics Extension from the Firefox Extension list.

Unfortunately the extension remains active and continues to disrupt my browsing experience.

How do I remove this extension permanently?

I lost my Outlook365 with the latest Windows 10 update. When I reinstalled I went through the preferences to select Firefox as my default browser. I have been using this for years and every time I picked a link in an Email it would open a new tab in my existing browser.

Now, regardless of anything I try it continues to open an new Firefox browser, with pages included since this started on the weekend.

What settings am I needing to make to correct this. I have gone through the config settings and selected 0 in the browser.link.open_newwindow.restriction with no success.

Hello there,

I am using WordPress, and the Video Player Element does not display on Firefox, although in HTML code is visible. The same problem appears in Firefox troubleshooting mode if it helps.

Do you have any idea what causes it, and how can I solve it?

Hi - I updated my Firefox / Mozilla browser yesterday and now all types of downloads are failing. PDFs and EXEs alike. I can't an error that says Failed.

And yet, when I use Chrome or Edge, the downloads work fine, soooo - not sure what is going on.

Can you please assist? Thank you!

Firefox: 127.0 (64-bit) Windows 10

I keep getting a popup about using an older version and creating a new profile. I already created a new profile a few days ago so I cannot keep creating new profiles every time firefox deploys a new version and would need to open firefox to update the browser version.

When I reboot a Windows 10 computer and click once on the Firefox icon on the Taskbar, (1.) Firefox does not open full screen although when closed it was full screen. (2.) A second Firefox window opens with Yahoo on a Tab and also not full screen. Please fix!

Whenever I try to download anything, it automatically fails. The problem just started recently and I don't know what could have caused it because I haven't done anything that could affect downloads to my knowledge. Things I've already tried are

• Reinstalling firefox (including full uninstall via "Revo Uninstaller"
• Updating firefox to the latest version (127)
• Disabled all firewalls
• Chose the save location
• Disabled all parental controls in windows
• Chose the "don't enable HTTPS mode" (https://support.mozilla.org/en-US/questions/1414064)
• Tried firefox & windows safe mode (https://support.mozilla.org/en-US/questions/1442742)
• Chose a different save location inside my computer (a folder other than downloads)
• Cleared download history
• Ran a chkdsk on windows

The thing is that everthing else of firefox works (browsing the web, watching videos, etc), it's only the downloads. It's also not a computer problem I think because I can download on other browsers (such as chrome and pale moon). Any help asap is appreciated.

Firefox doesn't allow a web message to be sent but Google Chrome does. After filling out the form at: SPECTRUM URGENT: FUNDING FOR THE AFFORDABLE CONNECTIVITY PROGRAM IS RUNNING OUT, I could not send the message because I got a message saying, "Please enter a 5 digit zip code." but I did enter a 5 digit zip code! I copied the URL into a tab of Google Chrome and there was no zip code error so I was able to send my message.

I cannot register a credit card at: https://www.retailservicescommercial.citi.com/USCRSF/CMLSVC/index.html?siteId=PLCR_HOMEDEPOT#sec/signon

I was told eventually after clearing cookies and site data and refreshing the webpage that it doesn't work properly with Firefox and that I needed to use Google Chrome or Edge.

Can this be fixed or not?
