Diễn đàn hỗ trợ Firefox

I am running Firefox 119.0 on Linux and am unable to stream video on many sites. I have tested a few sites, and the only site that actually works for streaming video is YouTube. The others either say 'Source Error' or just load forever.

Things I have tried:

• Accepting cookies (via site exception)

• Turned off Enhanced Tracking Protection for the site that won't stream video

• Turned off pop-up blocker

• Enabled auto-play of video and audio on the site

• Checked for updates of Firefox (but there are none available)

• Launched Firefox in Troubleshooting mode with all extensions and customizations disabled, but this makes no difference

At this point, after doing some online research and trying everything I can think of, I'm really out of ideas.

I would appreciate any suggestions or information anybody has.

Thank you

Ever since about a week ago, my Firefox just started... bugging. Twitch doesn't work, now Netflix doesn't work, basically anything that plays videos (except for YouTube) doesn't seem to be working.

On Twitch, if a person is live and streaming, upon clicking their stream to view it, it's suddenly offline, even if the chat is going and the "this person is live" notification is there. Netflix gives me a f7351 error. Websites with online media (like free movies on putlocker) have multiple streaming services attached and neither of them works.

I've cleared all cookies, cache, data and history.

This is only concerning Firefox, other web browsers work perfectly.

Extensions on my Firefox are as follows: BetterTTV, Dark Mode, DocsAfterDark, Facebook Container, FrankerFaceZ, I don't care about cookies, Instagram Dark Theme, New XKit, TinEye, Tumblr Saviour. No adblocks, no nothing.

My operating system is Windows 10, 64bit, Firefox is updated to 119.0.1.

Any help would be appreciated as this has been the bane of my existence for a while.

Wanted to export some bookmarks, and couldn't figure out why (latest Firefox) Bookmarks "Library" was missing relevant buttons/menus. (Screenshots attached.)

After testing, found they actually are there, but have have almost no contrast vs background - that is when "Manage Bookmarks" is called from a Private window. But things look fine when called from a Standard window. (No extensions; same in Safe Mode.)

Can anyone advise?

A simple workaround is to bring a standard window to the front first, but am curious if this is Firefox on all systems? Only FF Linux? Only the particular (default) settings of my Linux Mint 20.3 Cinnamon installation, and display? Not even sure a Bookmark management window is ever meant to assume the theme of the foreground window (here Private browsing's dark).

Thank you.

I can't find any way to group windows. Yes, "windows".

I have about three dozen windows open (yes, there are a lot of tabs in them), and not just at home. And it’s hard to quickly find your bearings when you need to switch to another task (workspace). It would be nice to at least change the color of the windows, depending on the type of work. But in the API API I don’t see the ability to define a window property where you can specify a group identifier, which can be used to restore the color after re-opening FireFox.

If FireFox had a built-in or its own reliable extension for organizing thematic work, a deferred workspace (without losing the contents of windows). Arc browser - they realized that what browsers have been denying for a decade is already overdue, and they will be able to take over the market.

I tried several extensions for saving, restoring and organizing workspaces, and came to a clear conclusion: only the built-in FireFox solution for restoring windows after a crash/opening is the only truly reliable solution. There is no trust in extensions that are not supervised by a good team of developers and testers; there is a guarantee that data will be lost in the near future.

It is possible that in recent years some expansions have been completed. I'd be glad to know about it if you point it out. But here a question arises on a separate topic: improving the mechanism for rating and testing extensions, recommended extensions program.

Dear Firefox Community,

my ff browser won't open the following websites:

https://www.haaretz.com/ (here it says: Error 54113) and https://archive.ph/ (this won't open at all without any notification)

Could you please let me know how get them to open?

Thank you!

I use a VPN connection to access my workplace. This means that all my DNS queries MUST go through the company's VPN tunnel.

Firefox is deliberately blocking my work. The DNS over HTTPS "feature" does not work over this VPN connection.

In Firefox, there was previously the following setting: Preferences > General > Network Settings > Enable DNS over HTTPS

I REALLY NEED to have this setting restored right now.

Contacted Specrum Customer Service because I couldn't login to my account. Rep told me it was a browser issue and suggested I try a different browser. I did so and was able to successfully log in to the Spectrum Site. What do you thing is the problem with Firefox and the Spectrum site? Everything else I log in to works fine.

In the past when I reinstalled Windows and then Firefox, I would sign into my account and all my bookmarks/addons etc. would automatically get reinstalled. Today I had to reinstall Windows and when I logged into my firefox account, nothing happened. Does Mozilla no longer keep these settings for us? I don't have any other devices to sync off of and never have, so where did all those settings come from when I did previous reinstalls?

Using text boxes such as comment sections in certain sites will "duplicate" the boxes directly over it Scrolling up and down will lock the boxes on screen and leave multiple traces of the text boxes Refreshing the page will remove the boxes temporarily but will happen again Happens inconsistently on multiple websites Site shown under is dcinside.com

When I went to watch Tubi TV today I got this error message when I tried to load the video:

"Oops, your web browser is no longer supported. Please upgrade to a modern, fully supported browser."

But only for a few seconds, then it shows

"Sorry, there was a problem loading the video player. Please try to reload the page. If you are using an ad-blocker, please disable it or whitelist tubitv.com If the problem persists, please contact us at tubitv.com/support"

I booted my firefox in safe mode, still get this exact sequence of events. My firefox is up-to-date. Is there a workaround for Tubi blocking content from firefox browsers? Is that what this is? Thank you

hi Edge is 2x faster then Firefox using Onshape 3D cad cad program Firefox picks another driver GTX 980/PCIe/SSE2 Edge use Gforce RTX 3060 PCIe SSe2 How can I make Firefox use the same driver as Edge

This is the link that Fox was reporting difficulties playing on a Mac running Firefox. I just ran it on my ancient imac using an older LTS version of firefox and am not having any problems (nor with chrome)- 

https://hlsjs.video-dev.org/demo/?src=https%3A%2F%2Fgyllp63pcjwbfl.data.mediastore.us-[…]mZhbHNlLCJsZXZlbENhcHBpbmciOi0xLCJsaW1pdE1ldHJpY3MiOi0xfQ==

I was using Lightspeed today, and the website pops up a confirmation dialog box (probably through JavaScript) so that you can confirm that you want to do a specific action. I got annoyed with the dialog and clicked the included "Don't allow this website to show prompts anymore" box when I hit OK. But now it won't perform any action that requires you to hit the OK in the prompt, so I need to make the dialogs come back so I can do my job. I can't find any setting anywhere in the browser that I have actually disabled or changed by hitting the box in that prompt.

Just pointing out the idiocy of this software... despite having tabs with multiple pages of the same host website open, Muppet-Zilla FireFux starts giving me the old Secure Connection Failed rubbish. Take the link, open it in public of MFF, it opens fine. Even a page that was open fine, try to open a link it, Secure Connection Failed rubbish. Hit the back key, A PAGE THAT WAS OPENED, then Secure Connection Failed rubbish. Yet in CCLeaner, Vivaldi, Chrome, Edge, no issues. So, I guess the message in that is clear - uninstall MFF, never install again. Good to know.

The box in Settings > General > Startup > Open previous windows and tabs is still unticked.

Does anyone know what could be causing it and how to fix it?

Thanks :)

I found an answer to this question, but I need it in English; how to do this if you're not a programmer. The new feature is beyond annoying, so if someone wants to work on making it optional, that would be a super improvement, but I'll be happy if I can just turn it off! Thank you
