Diễn đàn hỗ trợ Firefox

Hi I'm running Firefox 152.0.1, 64 bit, english version from Italy. From last updates I learned that a built-in VPN is available for users. I looked for it everywhere in Firefox toolbars and menus, but I cannot find it. Am I stupid or VPN can be unavailable in my local version of Firefox? Thanks!

Hello, I've been using Firefox for several years because of all browsers it's the only one (I know of) that has a setting whether to open links in new tab or in new window. I want them opening in tabs. This has been quite alright until last week when I was suddenly shown a message that I was using an old Firefox version and was forced to create a new profile. I did that but ever since then links keep opening in new windows - even though I have found the relevant setting and ticked the box "Open links in tabs instead of new windows". With or without the box ticked, the only way to open links in new tabs is to simultaneously hold Cttrl and click on the link. I've tried all variations of this box and the next two, but no luck. This is really important for me. What am I doing wrong? Thanks!

I am at a complete loss on this. A recent firefox update has shifted all my site logins and passwords elsewhere in mystery and impossible to recover nor find them. I tried "Restore bookmarks, passwords and data from an old Firefox profile" but the profile is simply not there and the instructions completely haywire. I have nothing on the profile page. What have you lot done to make this completely unusable for the small person ? I thought I was computer savvy but now firefox is making things unnecessarily invisible and over-complex.

New install of Zorin OS 18 and new install of Firefox 152 resulted in not displaying bookmark tool bar with the imported bookmarks. Tried adding a new bookmark which displayed after the import bookmarks icon but none of the old ones. Tried to import from HTML that reported done, I closed and reopened Firefox and the same toolbar display. Is this something with Zorin or Firefox?

Running windows 10. I installed the newest vewrsion of Firefox, and now I can see or find bookmarks anywhere. I tried the tutorial but I dont see anywhere in my computer where a list of bookmarks are.

last night when i closed the system down, i had 5 spacial tabs with names, and apx 50 other tabs open, come to start the system this morning.. all gone.. nothing.. just a new firefox.. all my history.. gone... this is not good, as the 5 spacial tabs that i had where from seriten sits that need to be their,and now.. just gone.. the lot... and all the setting are correct..

I have a problem loading the page "claude.ai". yesterday it was working perfectly but today Firefox shows me a blank page. I really don't know what to do. I tried to clear the cache, going in private mode, forcing a reset, closing and reopening. What's the problem? Thanks

Hi,

After the last Firefox update, the "Open previous windows and tabs" setting stopped working, and I need to use the shortcut "Ctrl+Shift+T" after each start to restore the previous tabs.

Is there any solution for this problem or there is a way to downgrade to a version where "Open previous windows and tabs" works correctly?

My current version is 152.0.1 (64-bit).

thanks.

Whilst using default firefox browser on my mobile, I am now being constantly referred to the 'about blank' URL page and effectively unable to access browser pages - Eg; social media Facebook etc, or age confirmation..

Now that you are killing all my profiles about the sixth time, and you still have TWO profile managers, not compatible with each other but happily killing each other automatically, with your automatic update...

I think I need to become serious.

We need to talk.

1. What is going on? 2. Do you know that you are now quickly eradicating your core, most avid user base? 3. There must be a serious internal trouble at you, or this.... what here is going on, should not have been allowed. What is that?

What is the mechanism what makes this... this... this thing really happening?

Already the idea, that you will use MULTIPLE profile managers in your own same product. May I ask you, whose wonderful idea was it?

(AI written summary of troubleshooting steps taken before making this support thread)

Firefox version: - 152.0.1 Release - 153.0 Nightly

OS: - Windows 11 build 26200

GPU: - NVIDIA GeForce RTX 4070 SUPER

Codec package: - Microsoft HEVC Video Extensions installed from Microsoft Store

Problem

Firefox does not expose HEVC playback support, causing Twitch to disable 1440p streams encoded with HEVC.

The same machine can play the same HEVC Twitch streams in Chrome immediately after installing HEVC Video Extensions.

Expected result

Firefox should report HEVC playback support and allow playback of HEVC streams, as Chrome does on the same system.

Actual result

Firefox reports HEVC as unsupported.

about:support:

codecSupportInfo: H264 SWDEC HWDEC VP9 SWDEC HWDEC VP8 SWDEC HWDEC AV1 SWDEC HWDEC HEVC NONE

Troubleshooting already performed

- Installed Microsoft HEVC Video Extensions - Rebooted Windows - Updated NVIDIA drivers - Verified hardware acceleration is enabled - Tested with a brand new Firefox profile - Tested with Firefox Nightly - Confirmed Chrome can play the same HEVC streams

Additional observations

Chrome: - Twitch 1440p becomes available immediately after installing HEVC Video Extensions - Twitch Stats for Nerds reports:

 hev1.1.6.L150.90.0.0.0.0.0

Firefox: - Twitch reports that the browser does not support the required resolution - 1440p remains greyed out - about:support continues to report HEVC NONE

Reproducible tests

Firefox console:

MediaSource.isTypeSupported('video/mp4; codecs="hev1.1.6.L150.90"')

Result: false

MediaSource.isTypeSupported('video/mp4; codecs="hvc1.1.6.L150.90"')

Result: false

navigator.mediaCapabilities.decodingInfo({

 type: "media-source",
 video: {
   contentType: 'video/mp4; codecs="hev1.1.6.L150.90"',
   width: 2560,
   height: 1440,
   bitrate: 8000000,
   framerate: 60
 }

})

Result: {

 supported: false,
 smooth: false,
 powerEfficient: false

}

For comparison:

MediaSource.isTypeSupported('video/mp4; codecs="av01.0.08M.08"')

Result: true

navigator.mediaCapabilities.decodingInfo({

 type: "file",
 video: {
   contentType: 'video/mp4; codecs="av01.0.08M.08"',
   width: 2560,
   height: 1440,
   bitrate: 8000000,
   framerate: 60
 }

})

Result: {

 supported: true,
 smooth: true,
 powerEfficient: true

}

Additional note

Setting:

dom.media.webcodecs.h265.enabled = true

causes HTML5 codec test (https://html5test.co/) to report H.265 support, but does not change:

- about:support - MediaSource.isTypeSupported() - MediaCapabilities.decodingInfo() - Twitch HEVC playback availability

Question

Is this a known issue with HEVC Media Source Extensions support on Windows 11 build 26200, or is there another requirement for Firefox to expose HEVC playback capability through MediaSource and MediaCapabilities when the Windows HEVC codec is installed and functioning in Chromium-based browsers?

How do I add the Translate icon to my Toolbar - W10 - please?

If I open the following page in Chrome it automatically translated from German to English. https://www.camperprotect.de/p/fahrer-und-beifahrertuerverriegelung-einbruchschutz-2006-2019

I cannot find how to translate it in Firefox. I do not have the Translate icon that is suggested.

Many thanks

Brian
