Firefox Support Forum

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.

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!

My Firefox is the most recent version 126. I am having trouble with pop-ups being blocked. I have added the website to the pop-up exception list. When I go to the site, it shows me the little icon showing I have added exceptions for this site. However; the pop-up still gets blocked.

The site is: https://www.foxit.com/ I try clicking the Log In drop down then Foxit Account. Before this would pop-up the log in screen for the site but since version 125, it does not. I just updated to version 126 to see if that resolved it before creating this post but it didn't. Thus I am here trying to get help.

I have had some issues using Firefox and I was told that the website works better with Google Chrome by a support person. For the last recent issue, I was told a website doesn't work correctly basically with Firefox and that I needed to use Google Chrome or Edge. I recently received an email from Mozilla which had a link to an article titled, "Here’s what we’re working on in Firefox" at: link text and in the article in large print it says, "Bringing you the features you’ve been asking for." I didn't see any mention about increasing Firefox's compatibility with websites.

Hopefully, somehow comparability with websites will be made better.

Is it possible to install Firefox (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles. Nor is it about where files are downloaded by default.

Windows 11 is consuming nearly all of the C: drive. I badly need to get Firefox (and later Thunderbird) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

Most of the help I've found on the web is clearly outdated.

Thanks. jt

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.

Hi,

My computer was on during the week-end and when I came back home I noticed we had a couple of power outages. Computer restarted automatically (Win 10 22h2) and when I launched Firefox, it started as brand new with all my addons gone and none of the previous session restored (I had 4 Firefox browsers opened with each 20+ tabs opened).

I have tried looking at C:\Users\MYUSER\AppData\Roaming\Mozilla\Firefox\Profiles but found nothing of interest. Where is everything and how can I restore everything I had ?

I even tried Troubleshooting mode and downgrading to a former version of Firefox (126.0.1 64 bits).

Thanks,

Why is Firefox backing up my bookmarks in a json file, when Firefox itself doesn't recognise the file type when trying to restore said bookmarks? I WAS able to restore my bookmarks by converting the json file at https://www.jeffersonscher.com/ffu/bookbackreader.html. But why can't Firefox just back up as an html file like it used to? I had to go off searching the internet for a solution, turning what should've been a 5 minute job into nearly an hour 😕

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

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

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?
