Diễn đàn hỗ trợ Firefox

I was receiving Directv content on Mozilla Firefox for months without issue. Suddenly it stopped completely and left a message "We couldn't play this content at this time". I don't understand why this happened or how to fix it. I want to do all my browsing with Mozilla Firefox so I need help. It would be truly excellent if I could speak to a human about this issue. Please.

Recently my system updated Firefox to version 149.0.2. It works great! However, it will not display my homepage which is yahoo.com. I can go to any other website and everything is normal. But when I click on the little house for "Homepage" it briefly displays and then goes blank.

This does not happen when I use a different browser.

Please advise.

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.

When there is a field to fill in my credit card info, the info will appear and let me select the CC I want to use but when I move away from the field the CC info goes away.

I'm on Debian 13 stable with firefox nightly (tarball) downloaded from the firefox website with firefox running on wayland. I don't recall the exact time / build that this issue happened, but it has been persistent for over a week or two already.

The issue I am seeing is where secondary menus or popups do not scale properly in firefox. This includes Popups for extensions, right click menus, or even link previews (long click left mouse btn).

Things I tried with no luck:

• Restarting my computer
• Restarting firefox / Updating firefox from the firefox website (https://www.firefox.com/en-US/channel/desktop/)
• Changing my display scale (100%) to (90%)
• Changing firefox display scale from (130%) to (100%)
• Refreshing firefox through the settings (aka clearing extensions and all the other stuff)
• Switching to X11 and back to Wayland... X11 worked fine, but back to Wayland just got things borked again
• Updating all system packages on Debian (nothing much except for security updates on debian stable)

Now the questions I have:

1. Is there a way to fix this issue? 2. Where could I file a bug for this issue? 3. Are there other people with this same issue?

When I hit enter after clicking youtube.com , my screen turns into grey spots where the videos should show and no other written info on screen. What is going on??? I can go in when Safari or chrome.

When I click to fill in a Credit Card field to pay for something, my correct card info appears momentarily, but then disappears. To execute a payment, I am forced to manually fill in all required information. I made sure the "save autofill" box was properly checked in the Settings, and it was. Names, addressed, etc. are all filled in properly; only credit card info is not.

I have credit card auto-filling enabled and several credit cards active. However, most of the time, when I go to use the autofill, though the card choices appear and I am able to select one, and it usually temporarily shows the fields to be filled, when the menu closes, the auto-fills are gone! It's worse than not having autofill at all. This seems to happen the majority of sites where I try to use it.

I have used gmail including calendar and contacts with Firefox for 5 years, suddenly contacts and calendar will not open, has a Firefox upgrade caused this problem?

I have had FF VPN for 2 days Pages load incredibly slowly Videos do not load at all

Do other people have experience with this?

I am no longer using the VPN

Sorry for my bad Englisch

Google is my home page. Every time I open the browser or return to Google, it request access to my location. I click "Allow" and I click the "remember this decision" box. I've done this repeatedly and still Google bugs me with an access requests. This started with your last update which included the VPN. I have a 2018 Mac Mini with macOS Sonoma 17.8.7.

How can I stop this annoyance?

I asked about troubles with passkeys in Microsoft password manager, not Windows Hello. The question was denied. https://support.mozilla.org/en-US/questions/1585824

I am only a home PC customer and have Windows OEM vendor's support only. It supports operation mises about Windows OS and preinstalled applications, but doesn't support Windows's bug trouble shootings. I was denied supporting from FUJITSU CLIENT COMPUTING LIMITED (known as a Japanese company, but a subsidiary of Lenovo now). I copied the raw Japanese text to avoid my failure of translating.

By the answer, I lost any support about trouble shooting.

I ask questions. Have Firefox development team previously confirmed that it works? Does you have Bugzilla ID about functionality check with passkeys in Microsoft password manager or something like it?

When i start fire fox it immediately opens 10 additional versions in the background which I can see in task manager and they take up a lot off memory. If i end task them they immediately come back. This only started recently. I noticed it because now when i open say a youtube video it shows it as number 4. This never happened before unless I had the same video open more than once.

If I can not stop this I will have to uninstall.

I had an unusual system crash, and when I restarted Firefox, the History > Restore Previous Session feature was grayed out. Due to the nature of my work, I had a large quantity of tabs open at the time of the crash (please don't judge). I then backed up the contents of the \Library\Application Support\Firefox\Profiles\[session].default\sessionstore-backups\ folder, but unfortunately not the full Profiles folder content. The file recovery.baklz4 does seem to contain my open session info (I can see a recent link in it). Based on web advice, I then tried restarting Firefox, but that didn't solve my issue. I also tried copying in sessionstore-backups files, without success. I then tried the "Session History Scrounger" web application to try and recover links from the contents of recovery.baklz4 because that worked for me in a prior crash years ago, but it doesn't seem to work properly anymore (it only retrieved 4 web pages). Appreciate any guidance as to how I can use my backed up sessionstore-backup files to re-enable Restore Previous Session, or alternatively to scrounge the links that were open at the time of the crash. Greatly appreciate your help! (Please do not suggest using "Show All History"... I have no plans to sort through a dump truck of rice with a pair of tweezers.)

i can see the video detected but when i click on the blue download button it says sadly we failed at downloading that specific video. It does this for youtube videos no matter how many times i try it. i never had this problem before and it seemed to have started in may of 2026

Hi there. Ian here. My home page "www.news.com.au" keeps wanting to lock me out due to apparent addblockers on my PC. I am not aware of any that I have installed and can't find a way to remove them or turn them off. I am also not sure if this is a healthy consideration in any case. Can you Help me please.
