I-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.

hi for some reason twitch.tv or some other websites will no longer play videos on my pc and i have no idea why, firefox works fine on my laptop

On Firefox browser, I cannot Copy a file in Studio Code Server (within Home Assistant). SCS is open in HA in a Firefox tab. I get the error popup "Unable to read from the browser's clipboard. Please make sure you have granted access for this website to read from the clipboard." "Learn More" links to https://code.visualstudio.com/docs/remote/codespaces#_how-do-i-allow-vs-code-to-access-my-clipboard-for-reading and the "How do I allow VS Code to access my clipboard for reading?" section. But I cannot find similar settings in Firefox's Settings menu.

Any suggestions please on how to resolve this? I'm sure I used ~ a year back to be able to Copy a file ok in VSCode on Firefox. Thank you.

Yahoo isn't loading at all for me, more specifically guce.yahoo.com. I have managed to get into the login.yahoo.com page and log in but after the log in process it goes to the first page again and gives me the same "The connection has timed out". I just installed the browser and this might make me not use it ngl. I have tried both clearing cookies and troubleshooting mode.

Hi, I used Firefox browser at work since it had the best add-in for tab groups (Simple Tab Groups). Unfortunately browser is not supported any more. Is there a portable version that can be run without installing, from Mozilla.

I read a post that indicated it was available from PortableApps, but am not conversant enough to know that it's 100% safe. Believe that it was able to be updated as well.

When I try to make a Google search I get the following message, "I'm not a robot" with a reCAPTCHA: "Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?". This happens on Firefox, but not Chrome or Edge. If I 'Allow' Google in the 'Exceptions - Cookies and Site Data' then I do not get the message, but it takes several seconds for Google display the resulting page. However, if I delete the cookies/cache the message will return and I have to redo the reCAPTCHA. I have scanned with Malwarebytes, Bitdefender, Hitman Pro, Trend Micro House Call and Microsoft Defender, nothing detected. Running Win 10 (64) with 'Extended Security Updates', Firefox 147.0 (64), no additional Extensions or Plugins. Also I uninstalled and reinstalled Firefox.

To whom it may concern,

I have an angular application accessing data from a 3rd party data provider. To get data, POST-requests are sent to the data provider REST API (https://capzlog.aero). The application works correctly using Google Chrome and Microsoft Edge. However, when using Firefox, the following error appears:

"Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://capzlog.aero/api/pel/public/externalsystemflights/GetMissingIDs. (Reason: CORS request did not succeed). Status code: (null)."

As the POST request contains basic authentication, a preflight-request (OPTIONS) is first sent to the data provider. This request fails when using Firefox (but not when using Chrome or Edge), see attached screen-shots.

I have spent 4 days on the internet trying to figure out a solution, but I could not solve the issue. I tried the following: 1) check the certificates of the 3rd party provider (https://capzlog.aero): There are no issues. 2) start Firefox in safe-mode, disactivating the "Enhanced Tracking Protecting", clearing the cache. 3) changing the following Firefox settings:

   security.enterprise_roots.enabled (true<->false)
   security.tls.version.min (1<->3)
   security.tls.version.max (2<->4)
   network.http.network-changed.timeout

I tried sending the "OPTIONS"-request using curl and it worked as expected:

curl --verbose -XOPTIONS -H "Access-Control-Request-Method: POST" -H "Origin: https://projectz.numericalsolutions.ch" https://capzlog.aero/api/pel/public/externalsystemflights/GetMissingIDs

I really do not know what to do anymore to solve that problem.

As the problem is impacting hundreds of users, I really hope there is a solution.

In advance thanks for your help.

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

Hi,

Recently, I have noticed that when using Firefox, if I try to view an embedded YouTube video on sites that I visit regularly, instead of the embedded video playing, I now get a message on the video window that says, "Sign-in to confirm you are not a Bot. However, there is no option to 'sign-in', so I am not able to view the video. (screenshot attached)''

I did a little testing and discovered 2 things which I thought were noteworthy:

1) If I turned-off my VPN (Norton), then the embedded video plays in Firefox without any issues.

2) If I access the same site within the Chrome browser then the embedded video play regardless of whether I have the VPN service On or Off.

Strange, but true !!

I cannot find any Firefox Settings that address this issue.

Any clues?

Thanks.

Is there any Add-on that will shoot a scrolling screenshot (full page screenshot)?

For reference, there's an excellent extension on Chrome/Brave called "Go full screen" which has simple but perfect functionality, one-click automation, saves as either .pdf or .png format to your downloads folder.

The other day I accidentally pressed a keystroke that changed a Firefox setting, and now it thinks I'm on a mobile device/displays sites in mobile view where possible by default. This has persisted despite restarts of the browser and the computer and has been happening since Sunday (Australian time). I've tried opening the Responsive Design dev tool and I've sent screenshots to a techsavvy friend (I'm totally blind and use a screen-reader, so couldn't tell this was happening until I tried to use a site that had a radically different layout in mobile view), and aside from not seeing an exit button or a switch to change device mode, he couldn't tell what was going on.

I'm stuck and need help! I would like to unmobile my Firefox!

I have various shortcuts saved on the shortcut page comes up after logging in. Its set to 2 rows.. I use it every day. Used it this morning and working perfectly. Been out and when I came back the page is totally blank. I've tried sytem restore to 5th October but makes no difference. I use Windows 10 and read that Firefox are continuing to support Windows 10 I'm visually impaired and use a desktop PC with a large screen. I'm not PC techically knowledgeable. How do I restore my shortcuts or how do I re create them?

So I need to update my Firefox Browser to 128 BUT somehow "Updates disabled by your system administrator." and as I am the only user I have never set up an administrator.

So I have had a look and I don't understand most of what I am reading.

So about:policies.... DisableAppUpdate true So how do I change that? I have looked at Reg Editor but have no idea what I am looking at.

It took me a long time to update to Firefox 121 because I did not like some of the changes Mozilla did to it like spacing between Bookmarks in the dropdown so to update again is a big thing for me. Attached as much as I think is relevant. Any help will be much appreciated.

Hi,

I'm currently on Firefox Developer Edition version 136.0b6, and for some reason the search bar no longer displays the https:// header. Is it possible to turn this back on?

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

Hi. There is a problem with video playback when skipping through the video using a playback bar. The video (but not audio) freezes at the spot when one skippes to another part of the video and re-establishes after a while (not so short while) to the part of the video that is currently played. I'm using Linux Fedora.
