Firefox Community Forum

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.

For the last few days, Firefox is being removed from my computer overnight and i have to re-intall the browser the next morning. Sometimes it's still there the next day, and sometimes it's gone again the next day. What i causing this and how can i prevent it from being removed? Jenny

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?

(See the attached image... the big blank space is where the video should display)

I'm on a Mac using Mac OS Big Sur, 11.7.10.

Videos will not play on Firefox, whether on Youtube, in social media, on websites, or whatever. Sometimes the video will play with no audio, sometimes I just getting a rolling wheel.

I have other functionality issues that may be related.

I don't want to close and restart all the time. I am considering changing to a new default browser over the issue.

If I switch to Chrome or Safari, the videos play fine. Which seems like my answer.

Once again I have experienced that my Bookmarks disappeared. Some months ago, I had a HTML backup made, for easy Import. Now I started out by shutting down Firefox, followed by a restart. That worked last time (without import) This time it did no change. I shut down Firefox, and restarted the PC....... no change. (without import) Then I shut down Firefox and restarted the PC. Opened Firefox, and wanted to import the Bookmarks from the HTML file. The system comes up with a message stating that the file does not contain any bookmark references. ( Opening the HTML file using Firefox, reveals that all bookmarks are there, and can be used ) I uninstall Firefox, and re-install it . Flw. I try the import once again, using the HTML file...... to no avail. What am I missing here ?? My final option appears to be moving the bookmark one by one.. rather time consuming.

Is there a way to remove specific stories from appearing? I'm Canadian and do not wish to see what the US President has done in these stories. Google News has a hide feature for specific keywords. Does Mozilla?

I continue to receive this message when I open the browser. Fix "The bookmarks and history system will not be functional" error message

I have attempted to correct this with the various workarounds to no avail.

Anyone who can help with this?

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.

"Error code: SSL_ERROR_RX_RECORD_TOO_LONG"

   This message shows when a spam quarantine program updates in my Thunderbird mail (3 times daily)  Where do I adjust the record length to allow viewing ?

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.

my delete history has not been working since yesterday. I have not changed anything to my knowledge in settings so please help in correcting this. I have looked at settings and not sure if something changed or ?

I have not used private settings at all.

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!

Firefox is my default browser. The problems have arisen from around December 27th 2025. Till then everything worked smoothly. The first problem is that if I go to google.com then search for say , “Wordle”. The search output is displayed on the screen but when I click on the search result, it does not go anywhere- nothing happens.

The second issues, is till the problem cropped up, I had set google.com as the custom url for home page and windows through settings, home, and had used an extension, “ New tab override” available from Firefox, to set every new tab to open as google.com The url for the webpage works but the new tab override does not. I have tried removing the extension but problem 1 persists.

The third issue is that I have subscriptions to newspapers and had set up the logins. These newspapers are in my bookmarks. When I click on the bookmark the main page opens but the login area is missing. It tells me to get a subscription. e.g., among others, NY times, Uniqlo gb, the Turnitin of my university will not load although I am logged in to the university. I have cleaned all cookies, removed all extension including Ad blockers to fix the problem, tried resetting all to default setting but nothing works. Would appreciate any help you can provide. Thank you.

In order to connect to Amazon using Firefox on my PC, I am required to scan a QR code with my phone and then, presumably, connect via Firefox or Amazon apps (instructions woefully unclear). It NEVER works. It's no big deal, but it is annoying, particularly since I want to use Firefox as my default browser. I can always connect via Google or Edge. For those of us who aren't tech savvy, why don't you add standard two-factor authentication or Windows Hello as an option?
