I've been using Firefox since forever but over the last couple of months, the auto translate subtitles (to English) hasn't been working when watching Youtube videos. There's a thread on the Youtube support site with nearly 40,000 posts of people with the same issue and tonight I was trying to watch a video where the hosts talk in Italian, so I use auto translate to English subtitles but no subtitles appear. It will show Italian language subtitles.

I've gone back through this Youtube channel's history trying videos I've previously watched from months/years ago when auto translate used to work but even they're not working now.

I decided to try the video in Edge browser and to my surprise the auto translate to English worked there. They also work in Chrome.

So what could be causing this issue on Firefox, which started about August time?

This is quite bizarre as I assumed all the processing/translation was done by Google/Youtube so in what way can Firefox be part of this issue?

To be clear, subtitles in the (foreign) language the people are speaking, works. Subtitles translated from that language to English (or other languages) has stopped working. Subtitles translated from that language to English IS working on Edge and Chrome browser.

Over the past six weeks I have had two failures of Firefox [running current version 146.0 (aarch64)] in completing CC payment processes -- at least one involved updating an expired car, I can't recall if the other involved such a change or just entering a card.

I am using Firefox on a mac mini M4 Pro running macOS Sequoia 15.7.2 (up to date, fully supported, but not Tahoe the recently released new version of macOS). I am running Firefox with 4 extensions -- 1 Password, Print Friendly, Raindrop.io, and Authenticator. None were being actively used during these incidents.

In both cases when I switched to Safari and opened the sites, I was able to successfully complete the CC changes and payments. So it does not appear to be related to a problem in my internet connection.

My questions are: a) has anyone had a similar experience with Firefox

     -- particularly incidents related to online financial transactions

b) if so, have you found a solution c) regardless, do you have any suggestions about the cause of the problem or changes to try

Otherwise, my experience with Firefox has been excellent and I am very happy with it, but this is obviously a frustrating and time-consuming problem.

I have reported it to Firefox -- the response was that they will look into it but that my next step should to ask "the community" here.

My thanks in advance for any help or suggestions.

Bob

Greetings Ya'll,

I have to apologize if this is a double post, but I came back to the forum, & wanted to see if there were any responses, but i could only find my post listed under "My Profile"/"My Questions".

My original post was made Dec. 19-2025

=======================================

Early this morning as I went to use the Firefox browser, on My Desktop, I got an update, & then firefox opened, somewhat.

The homepage did not fill in with favorites, suggestions, etc, and in fact all that did load was the Search bar, but not one of my usual website buttons. The "edit", "help", etc. buttons at the upper left hand corner did load, but that is all. Not one of the buttons work, nor can I close out the Firefox page, by tapping the "X" in the upper right hand corner.

The only way that I could close out the "Firefox Page" was by going through the "Control/Alt/Delete" & then "Signing Out", which would initiate a "Re-start". Once I signed in, I could return to the Desktop, where everything works.

I use Firefox as my Browser on my Android phone, & at this moment, I've not had any problems using Firefox on my Cell Phone.

The only way that I could get to the Mozilla Website was by using the Microsoft Edge Browser, which is not giving me any problems as far as accessing the Internet!

How can I correct this problem, & go back to the Firefox Browser?

Hi,

In the search bar (I’m not sure about its official name), my previous searches used to appear as suggestions before Google’s own suggestions. However, since I changed my default search engine from Google US to Google UK, it no longer seems to remember the searches I make. I’ve tried switching back to Google US, but that didn’t restore the behavior. Do you have any idea how to fix this?

For example, I previously searched for “things to see in Latvia”, which is why it appears as a suggestion in the screenshot. But if I now search for “things to see in Louvre Museum” and then try the same search again a few hours or days later, it isn’t saved and therefore doesn’t appear as a suggestion.

Thank you!

I have had Firefox using autofill for credit card payments for years--just replace my iMac with a new Mac Mini, and the credit card info still pops up when I am making a payment, but it will not autofill.

I have at least one question on the support forum which has never been answered. So I went to Bugzilla, and discovered dozens of YouTube issues under the Open/Unconfirmed status.

I can reproduce my problems. I'm sure others can reproduce their problems. Nothing is done. NOT EVEN admitting there is a problem.

If I can't use YouTube on Firefox (I can't), then why am I using FF? It is one of the biggest sites on all of the internet. But FF apparently doesn't care if it doesn't work.

What. Is. Going. On?

I - unwanted - have a second line of BOOKMARKS above the one I selected. HOW DO I GET RID OF unwanted BOOKMARKS?? SEE PICTURES I TOOK OF these TWO ROWS OF BOOKMARKS, thanks, sfd

In Firefox, the animation exhibits performance issues like stuttering, particularly in elements that rely on animateTransform and animate for movement or opacity transitions. This issue is not present in Chrome, where the animations run smoothly without any noticeable lag.

Expected Behavior: The animation should render smoothly on both Chrome and Firefox without any stuttering or lag, providing a seamless experience for users.

Steps to Reproduce:

Open the provided SVG code in Firefox.

Observe the animation, particularly the elements with animate and animateTransform attributes.

Notice the stuttering or lag compared to the smooth rendering in Chrome.

I seem to have lost all of my bookmarks & i have tried to Import and backup / restore in manage bookmarks tab but all i get is a message "unable to process the backup file" plus when i tried to bookmark a web page by clicking on the Star bookmark icon nothing happens now for some reason. Was there an update as this only just started around 2 days ago

Stupid mistakes were made - I reinstallted windows and when I opened firefox I realized, that I did not know my password and also was not sure about the mailadress. I finally found an account with my mailadress but reset the password - it said that all data in the account will be deleted if I do that.

I got the old files recovered, but everytime I copy paste the old key4, login and cert file... nothing changes withing the browser. If I copy the whole old profile folder and exchange it with the new one and then I open firefox it just says "profile could not be found" and then firefox closes.

Is there any chance of recovering my old saved passwords or did I screw up entirely ?

'I was sent a link that goes to a learning site by my future employer to take some online classes via email. Every time I try to access the site I get a message that I need to close the page as the website may be impersonating someone trying to steal my information. I use Safari, not that I have a clue what it means, is this a restriction issue I need to avoid or sidestep like a firewall or something similar? I tried typing the web address and the HR office says not to do that - to only use the link. How can I check what’s wrong so that I can take access the online classes for this position?

In the Security Measures overview, under Manage Passwords, I see the following: 3 passwords may have been exposed through data breaches.

All 3 websites with data breaches belong to Facebook.

I permanently deleted all Facebook accounts more than 3 years ago.

Without Facebook accounts, I can't and don't need to change my passwords, right?

Thanks and regards

Hi Mozilla Community,

I am running Firefox on Windows 11 and I'm encountering a strange issue regarding the UI updates.

The Issue: My Firefox browser updates automatically to the latest version. However, my Default Profile is visually stuck on the old UI design. It does not reflect the recent interface changes associated with the update.

The Troubleshooting Context:

• I have verified that the browser itself is technically updated (via Help > About Firefox).
• The strange part: I have other Firefox profiles on this same machine. When I launch those profiles, they correctly display the new, updated UI.
• This issue is isolated strictly to my main/default profile.

Has anyone experienced this mismatch where the version number is correct, but the UI fails to refresh on a specific profile? Is there a specific fix for this?

Thanks in advance for the help.

When I click on the URL bar, the entire URL is highlighted. Then, if I click the left arrow, it brings my cursor to the start of the URL. After it moves my cursor, it then prepends the URL with the protocol (https://, http://, etc). My cursor is now no longer on the left side, and I need to hit my left-arrow key several more times to reach the left side.

Here is a screen recording of the issue: https://youtu.be/JtoL88bqSB0

Ideally, it would bring my cursor to the left side of the protocol, or show the entire URL, with protocol, in the URL bar, so that it does not need to prepend it.

Pages won't load, including the firefox home page, or the autoupdate URL. My home page news stories load no images.

The Firefox .dmg downloaded and installed over previous version. Firefox failed to load any pages. Firefox deleted from Applications folder and moved to Trash. The Firefox installation file downloaded again. Firefox failed again.

This is a bug report. The browser does not function.

Troubleshooting Information would have been added, but it included personal information. Sorry. "userAgent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:146.0) Gecko/20100101 Firefox/146.0" Specifically, Firefox/146.0.1 (64-bit)

Windows 10 and cannot upgrade to 11. Firefox is current.

Pages began to open slowly so restarted computer, which fixed that issue but the bookmarks (happens often), Bitwarden & Instapaper icons were missing from the toolbar. I managed to retrieve the bookmarks but while attempting to restore the icons, the puzzle icon disappeared, which, after many hours I did manage to retrieve.

The boxes that open after right-clicking on the gear or puzzle icons do not match what the multiple online help suggestions show (I cannot take a screenshot of what I see in my drop down menus). I have deleted and reinstalled Instapaper and Bitwarden to no avail. Multiple suggestions from Bitwarden emails did not work and they suggested that it may be a Firefox issue.

Also, videos will not load but will load on Microsoft Edge.

Hello Firefox Support,

I am experiencing a consistent and disruptive performance issue that occurs immediately after certain complex web pages (particularly those with heavy scripting or dynamic content) have fully loaded.

The symptom is a temporary but complete freeze of the Firefox window, often lasting between 5 to 10 seconds, during which time the browser is completely unresponsive. This freeze is accompanied by a significant spike in CPU usage (often reaching 90-100%, according to Task Manager/Activity Monitor).

Details:

Trigger: The freeze reliably occurs right after the page status changes from "Loading" to "Done." I suspect it is related to post-load scripting execution or rendering finalization.

Impact: Any ongoing user interaction is halted until the spike subsides.

Tested Scenarios: I have replicated this on multiple sites, including heavy news aggregators, social media feeds, and complex web applications.

Troubleshooting: This issue persists even after:

Clearing cache and cookies.

Running Firefox in Safe Mode (disabling all extensions).

Creating a new, clean Firefox profile.

This severely degrades the browsing experience, especially when quickly navigating between tabs or starting a session.

Could you please investigate potential issues within the core rendering engine or script execution scheduler that might be causing these severe post-load processing bottlenecks?

Thank you.
