Diễn đàn hỗ trợ Firefox

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.

Hello, When I view some pages with inline video graphics, I see a garbled video frame. I have attached a screen grab from part of one screen. I have no issues with YouTube or other videos. It's just the graphics of some webpages such as looking at an Apple product on their site. I have not had this issue using Chrome under the same conditions. It's like I have a corrupted Codec or something. Does anyone have any suggestions? Thanks.

Popups for Smithsonian magazine keep appearing, sometimes 2 at a time, despite having popups blocked. I need them to stop. They are annoying and cover up content of web pages.

The mute tabs icon is just a waste of space as soon as you get a few tabs loaded and the tabs shrink. I have multiple tabs showing at the moment where I have clicked on the icon and unmuted them when just trying to select them. It does not help that the icons have been placed in almost the exact centre of the tab, at least with the 19 I have showing in a mix of muted/unmuted. Only 7 of these tabs are still muted, although I did deliberately unmute one to check the action.

I would prefer it if these icons are not showing as they are a waste of space and my time. If you hit the icon the tab is not brought to the front as intended so you have to click on them again. I just want the tabs to work like real tabs.

Is there any way to remove the feature altogether? I have after a lot of frustration just reduced the sound for Firefox in the Windows Volume Mixer as I did before tab muting was thought of. I almost never use sound in Firefox anyway.

Firefox tabs start crashing all of a sudden and won't stop crashing, until BSOD happens.

In my case it caused PFN List Corrupt Blue screen error.

How can I identify the real reason for the crash of the tabs, leading to the crash of the system?

Every time I access the web I get a report from Norton saying "Threat secured". It attaches every single website that I open. See attachment for some exmaples (only variabole part of message shown apart from first one).This is occuring 50+ times a day but does not occur using Edge, so it appears to be related to Firefox. PLEASE help. Norton have not helped with this. Thank you- Colin O'Brien

Firefox releases email addresses and our data to third parties!

I installed the Arc browser and Arc offered to load my bookmarks from mozilla. Out of curiosity, I let it, and it loaded my bookmarks and folders smoothly. Arc didn't navigate Firefox to the login page, so Firefox released my information without asking me.

What probably happened in the background was that the Arc browser told Firefox which email address it was requesting data from, and Firefox handed over the data to it "on notice". Firefox was not even convinced that the real owner of the email address asked the Arc browser to synchronize the folders.

Is it the famous Firefox reliability?

Firefox is deleting my website exception list whether I have "Delete cookies and site data when Firefox is closed." checked or not. It is the same with the exceptions list for logins.

I'm trying to log into this page: https://accounts.firefox.com

The sign up or sign in button doesn't work. The first time I click it, it immediately refreshes. I click again and nothing. On the 3rd click, it just spins for 30 seconds then goes back to being blue. This continues every time I attempt to click further.

I can login on this page just fine using Firefox on my android phone. I can also login using the Edge browser. Matter of fact, I had to use Edge so I could post this issue.

This is a completely fresh install of Firefox, on a completely fresh install of Windows.

Hello,

This started happening recently, in the last 30 days. Gray screen is shown when I clink on any photo in "Your memories from this day" email from photos@onedrive.com. If I go to OneDrive, then select today's date the issue is the same.

I've tried the same actions in Chrome and the photos are shown without issues.

Can someone help with this?

Had it yesterday, happened this morning after the restart and just NOW, when I entered 6 lousy tabs, and they are NOT in the recently closed list either.. wups, gone, no tabs, setting has a check mark on open previous windows and tabs. Within 24 hours, lost the tabs three times with a non reported crash and Firefox closing itself with no warning.

I honestly do not think I am responsible to keep a backup of my browser history, I expect a browser to do that. I switched from Opera to Firefox not to long ago.. even Opera is a security risk.. at least it doesn't delete your tabs just for fun.

Very simple.. that happens once more and i am OFF this browser....

Trying to recover from a hard drive crash. Had to buy a new desktop with Windows 11 Pro (looking to be a bad move). I downloaded/updated to Firefox 126.0 (maybe also looking to be a bad move).

Have my last "working" userChrome file (it took me weeks to perfect this to my needs).

I am looking for: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

but there is no "AppData" folder. And there is no existing userChrome.css file, anywhere!

Is the functionality I am looking for a thing of the past?

Is Firefox not completely supported by Windows 11?

If so, what is the last version of Firefox that will still support userChrome.css?

I am using Firefox 125 in Windows 11. And this just happens recently.

Sometimes, quite frequently, when I click the addressbar wanting to input or select a new address. The Firefox UI freezes (before the dropdown list of addresses is shown). The video/audio/other effects are still working, and from task manager, it does not cost more CPU/mem than usual. But it does not response to key press or mouse action. All I can do (that I know of) is killing the processes. The problem does not seem related to "current" webpage I am browsing. And I have not installed new addons for a few months.

Any idea what should I look into?

Hello! I saw that the Test day event had started. In Firefox Beta, I entered messaging-system-action.testday in about:config, put it on a string and set the value to testday as it said in the instructions. When I restarted Firefox, the welcome window did not appear and there was also no letter S next to the search as it should be. Please help!

Thanks for the answers!

Hi,

am running firefox 127.0.1 on a windows 11 desktop. Numerous sites that use a captcha to login fail. In other words, the captcha never loads and I cannot login to those sites. Such sites include teamfaderpro, Coursera, and bandcamp. All logins fail as the captcha is required to be passed prior to logging in, but the captcha never appears and so when I try to log in, nothing happens and I cannot login.

I have tried the above same sites on the Edge browser and have no such issue, the captcha shows and I can login.

Just FYI, the agent switcher setting change recommended by others previously is not suitable. When I tried that fix I was unable to access a considerable percentage of the internet due to some cloudflare issue, so the agent switcher setting is not an option. So far, I have tried all recommended settings to fix this issue and nothing has worked.

I am surprised no one else is having this issue.

Any help is appreciated, or at least inform google/mozilla about this issue as it has been ongoing (on and off) for me for many months. And yes, this problem is persistent for me at the moment, it remains despite rebooting windows, despite clearing cookies and cache (which I have set to automatically delete when exiting firefox).

I'm using a new PC with Windows 11 and find that I, inadvertently close Firefox with 16-20 open tabs. Most of the time when I reopen FF, the tabs are still there, as expected. Sometimes, the browser opens with just a new home page and the pinned and other tabs have closed. I can sometimes see the 16ish tabs in history and reopen them. More recently, I find that they are not in history as a number of tabs so I have to set them up again. This rarely happened on my old PC and if it did I would have bookmarked a group of open tabs that I used regularly.

The failsafe FF General setting is as follows: Startup, Open previous windows and tabs.

I don't know how I can stop losing my open Tabs but if I was able to bookmark all the open tabs to be used in case of a problem I would feel more secure.

How do I bookmark ALL or several my open tabs?

Recently Firefox has been randomly crashing the past 3 weeks multiple times, Is anyone else having this odd issue ? I'll be watching a stream or youtube video and bam out of no where the Browser goes black for like 20 or 30 seconds then crashes. I sent in about 3 crash reports and wondering if the Firefox team is aware of this issue.
