Diễn đàn hỗ trợ Firefox

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

I recently updated to 125.0.1 and now get 'failed to check for updates': - when I manually check (help > about Firefox) (see image) - in 'settings' it also shows 'failed to check for updates' (see image) I never had such a problem with previous versions; any suggestions?

Using the arm64 version of Firefox on a Surface Pro X causes several graphical issues. These issues started either with a update of Firefox or drivers.

This topic has already been reported, please see here for more information and documentation: Reddit: https://www.reddit.com/r/firefox/comments/182iojx/firefox_arm64_graphical_problems_on_surface_pro_x/ Mozilla Connect: https://connect.mozilla.org/t5/discussions/firefox-arm64-graphical-problems-on-surface-pro-x/m-p/52086

What can be done to report this issue and help it getting fixed?

I tried clearing cache and temp files. I tried a new profile. I tried a fresh install without logging in on account. Tried disabling all addons, running in safemode and incognito. Nothing works.

When opening in Chrome, it works as always. Same computer.

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

I am having a significant issue with firefox draining my battery. I used chrome up until the new year and then switched over to firefox from chrome. Overall I love firefox so much more. The format is way more pleasing. I love how it easily signs me back into everything, BUT IT DRAINS MY COMPUTER SO MUCH. Like i used to have an 8hour + battery span my laptop neverrr died. Now I get through MAX 2 hours of full use before needing to charge, and maybe 4 hours just having it at school but not using it.

I thought my dell suddenly started crashing, ran all these tests, and then I realized the only change was that I had started using Firefox... So sad I think I am going to have to leave it.

I read a lot of articles and did everything suggested. my graphics is webreader , i turned on all the suggested features, i have 2 extensions , the only thing I could maybe think of was that I use an animated theme so maybe that was killing the battery, but like if I can't use my theme than whats the point.

I like to split windows so I can have running YouTube videos on the left half of the screen and browsing the web on the right. If I open another site on the right side of the screen that has multimedia (ESPN, CNN, IMDB), the video freezes on the YouTube window but audio continues to play without issue.

I have done the following troubleshooting steps:

• Hardware acceleration turned off/on
• cleared cookies/cache
• A few About:config fixes

Videos don't have a problem running if I open YouTube with Chrome and continue to use Firefox for surfing.

Hi!

I get repeated messages that I use an old version despite having downloaded the most recent version. When i try to start Firefox it won't start, I only get a message and the precise wording of the message is" You've launched an older version of Firefox Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox." Then I get two choices, either "Exit" or "Create New Profile". If I choose the first, I exit. If I choose the latter and create a new profile then I loose my bookmarks and browsing history. Appreciate any solution you might have

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

Since a couple days ago I cannot Copy anything in Firefox. Be it with CTRL+C or RightClick>copy. I can paste juste fine, and it works on any other app and browser I own. I tried to restart in safe mode (no add-on) but the issue persists. I ended up resetting firefox and it solved the issue... For a couple hours.. then it came back and I can't copy anymore. I did check that I was using the latest version of Firefox windows. I only have two add-ons, but since in safe mode it still doesn't work I'm not sure it's related to that. I also checked that Firefox was allowed in the firewall (I don't know why that would help but a forum said to check that).

Thank you for your assistance:)

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

I have used Firefox since forever, was a Netscape user in the past

But for about 3 months Firefox simply is no good anymore\

It is more and more sites I can not access with Firefox and have to use Edge instead.

Last example, just now

See screens attached

This is just one example, many other sites simply do not open, or open properly, in Firefox

WHAT IS HAPPENING?

Thank you

Whenever I attempt to watch something on any streaming service, I get an error message from the streaming service and a note from Firefox saying "The WidevineCdm plugin has crashed." I have tried to solve this problem a number of ways, but have unable to find a solution.

My best guess is the problem is due to the most recent WidevineCdm update, as in the plugins settings the most recent update for the plugin was on 10/21/23, which is shortly before I first noticed the problem. I did test out various streaming platforms on other computer browsers (Chrome and Microsoft Edge) — they gave the same website errors as I got on Firefox, but those browsers did not indicate the cause or suggest which plugin failed. I additionally tested out desktop apps for some of the streaming platforms; they work fine without any issues, but unfortunately the main streaming platform I use doesn't have a desktop app and only works in browser.

My computer is a Lenovo Yoga 9i, it's running Windows 11, and everything is up-to-date.

The methods I have tried to fix this issue with, to no avail: - submitted crash reports - toggling the "play DRM restricted content" options in Firefox, and toggling whether or not the WidevineCdm was activated, closing the browser between each toggle of options - clearing Firefox's cache - running Firefox in troubleshooting mode to make sure it wasn't a different extension interfering with it - tried running Firefox in compatibility mode - tried to find support from the people who made WidevineCdm, but apparently they don't do end-user support - deleting the WidevineCdm manually from the program files for Firefox and Chrome (since Firefox says the plugin is from Google), and then reinstalling it via the chrome components page. This briefly lead to the message on the plugin page that WidevinceCdm would "begin installing shortly." It seemed frozen like that for a good while, but then I tried clicking the "check for updates" and that message disappeared, and it went back to crashing when I tried using a streaming service. - uninstalling both Chrome and Firefox, restarting the computer, then reinstalling both browsers

As far as I can tell, the plugin comes automatically installed in the browser, and there isn't an alternate plugin for decrypting DRM-restricted content. If there's a way to set the WidevineCdm to a previous version before the update that's crashing it, I haven't found it, but I am no expert in computers or coding, and my guess about it being caused by the recent update could be wrong too.

I'm at my wit's end here, any help fixing this problem is greatly appreciated.

Hello, today firefox has been appearing as a blank icon on my taskbar. I have tried solutions suggested in older posts but it did not help unfortunately. if i try to

1- right click unpin from taskbar the icon shows once more. 2- right click, the icon disappears/becomes blank. 3- click pin to taskbar, the icon remains blank.

attached is the image showing the steps i described above

I frequently open new tabs by right-clicking the current tab and choosing "New Tab" from the context menu. Naturally, I want to start typing a URL or search term.

But the focus/cursor/caret is nowhere and typing does nothing. I have to click on the address bar, and then I can type.

I'm not using New Tab Override and I have Firefox's new tab set to a blank page.

I tried disabling all my add-ons, but I still had the problem.

I tried setting new tab to the Firefox home page and for a short while I got a cursor in the address bar. But the problem returned after a few hours

Any clues on what might be wrong? Firefox version 120.0.1 (64-bit) on MacOS Ventura 13.5.1. Thanks!

(A similar problem is described here: https://support.mozilla.org/en-US/questions/1420220 -- but in my case this is not a container tab.)

Hello, I am running Ubuntu 22.04 (Firefox v 121.0) on a custom PC. Ryzen 5700G, 32GB Ram, 2TB Storage, and a Radeon RX 580 (just to give some insight into the system in case it is useful). I use multiple mozilla services and haven't had many issues up until now. Everytime I open Firefox it immediately it fires right up, the moment I try to open a tab, search, etc.. it begins to lag. It will then freeze the browser and my entire PC soon follows suit. I have had to hard reset the PC about 3 times now. I originally had the snap version installed and thought that installing the deb package would fix the issue. I completely uninstalled the snap version and turned off unattended installations in case the system tried to reinstall the snap. I then installed the deb package and fired it up again, only to have the same issue. I have ruled out a couple of things on my end. I entered Firefox Safe Mode and unchecked all of my extensions (the only ones I run are Ublock, Bitwarden, and Relay). I ran a mem test and have been monitoring Psensor to ensure the CPU wasn't overheating (both of these tests were fine). I also scanned my entire PC to ensure I did not have any viruses (clamscan reported no viruses). I have been running my PC for about an hour now without starting Firefox and using Chrome, and I have had no issues with freezing or anything similar to what happened with Firefox. Not sure where to go from here. I love using Firefox and would love to get back to surfing as soon as possible! Any tips/help would be greatly appreciated! PS I could not find any logs about the session. I looked in ~/.mozilla/firefox/Crash Reports/events and couldn't find anything. If there is another place they are stored let me know and I would be happy to send them. I just don't want to open Firefox until I feel it is safe for my PC.

I forgot to add: I disabled hardware acceleration as well, did not fix the issue.
