Diễn đàn hỗ trợ Firefox

Is it a known issue that opening JIRA web pages immediately crashes and closes the Firefox browser on Windows 11. It never happened on Windows 10 however due to Windows 10 end of life we've been forced to upgrade at work. Now this crashes on a key webpage (we're software delevelopers). So we might have to change to Chrome which I really don't want to do. It would be great if you could find any or many crash reports I've filed and fix the issue.

I've copied the crash report info here in case its of use.

useragent_locale: en-US This report also contains technical information about the state of the application when it crashed.

They play for a couple of seconds, then the panel they are playing in goes black. They used to work a month or two ago. Videos play fine in YouTube. They also play fine in apps like VideoPlayer and VLC. They play fine in Chromium based browsers Opera, Brave and Vivaldi. My graphics card requires switching acceleration off. I can’t find a switch for that in Firefox.

Problem Videos start playing, then after a few seconds the video panel turns black. Audio may continue. Refreshing does not help.

Environment

   OS: Fedora Linux 43
   Firefox 147.0.1 (also tested Firefox Flatpak)
   Display server: Wayland and X11 (both tested)
   Hardware acceleration: on and off (tested)
   Media Source Extensions: enabled (disabling MSE triggers an “unsupported device” error)

What works

   BBC News videos play correctly in Chromium-based browsers (Brave, Vivaldi)
   Videos play correctly in mpv/VLC
   Other video sites (e.g., YouTube) play correctly in Firefox

What I’ve tried in Firefox

   Disabling hardware acceleration
   Disabling VA-API
   Disabling WebRender
   Disabling RDD sandbox
   Running Firefox under X11
   Using the Firefox Flatpak build

None of these measures help. This suggests the issue is related to Firefox’s interaction with BBC’s player on Linux. Has anyone else seen this, or is there a known workaround?

Hello,all, The built-in translation button in Firefox disappeared on the Reddit website.

Please add a fixed access key for the 'Translate button'. I also recommend introducing an automatic website translation function. Thank!

Hi Mozilla I hav got a problem with Firefox on Kubuntu 24.04.3. Everytime the computer is restarted Firefox crashes the first time it's started. That's not a big problem, starting Firefox again don't take long. But the problems is exceeding. If i start Firefox by clicking a link in a mail in Thunderbird. And Firefox has not yet been started, It crashes, but now it's also invaliding the Task bar on the screen where Firefox was started. Invaliding means that I cannot start apps from that screens taskbar, and the clock has stalled, none of the tools works etc. The only possibility solution I have been able to figure out, is restart (It's like going back to Win 98). Sometimes I am able to start a app from that invalid taskbar. But it's not the one app that i clicked on. Even though I can trigger it via Thunderbird, the invaliding of the taskbar will occur after a while. And I have to restart. I am not sure if this is the right place to post. But Firefox is always involved, but maybe Thunderbird or Ubuntu was the right place? Every time Firefox crashes there is send a crash report to Mozilla, but is has been going on for a while, so i guess that nobody is looking at the crash report. If I use Chromium instead of Firefox I don't see the problem.

Crash submitted, ID = 320cc808-4505-4cba-6e0f-9f2c2955d007 Still happens in troubleshoot mode. Still happens with extensions disabled (Ublock origin, Proton Pass) Started happening since Dec. 5, 2025 System is current with all Debian?Ubuntu updates installed (daily refreshes) Linux Kernel 6.8 on Lenovo Yoga i7 (ca. 2022) with Intel i5 & Intel graphics

Since Flathub list the org.mozilla.firefox app as official, i hope this is the correct support channel.

Recently i switched from distro specific package managers to flatpak as my application provider. The firefox flatpak won't play most embedded Video/Media on applications like in-browser fediverse clients, forums, blogs or wikis. Youtube works without any issues, Twitch is fine until there is an adbreak. Then it sometimes stops with the supported format/mime error (screenshot appended), only recoverable by cache-dismissive reload.

I used this Article https://support.mozilla.org/en-US/kb/audio-and-video-firefox and the links it contains to debug without any success. None of these samples play. just shows supported format/mime error https://test-videos.co.uk/bigbuckbunny/mp4-h265 At this test website 1. and 3. example won't play. I provided a screenshot before and after trying to click play on all the examples. https://www.tekeye.uk/html/html5-video-test-page

Contrary to the observed behavior about:support#media claims Software Decoding supported for everything except HEVC.

Chromium Flatpak has no such issues. So i copy the video url and play it with chromium. You can see: dire times.

The previous version allowed me to have Firefox as my browser and Brave as my search engine. Now Brave is both my browser and search engine. In the general settings, it says Firefox is my default browser. I'm confused. I just want to be like it was before the update. Please help.

Hello! See the screenshot please: so, I downloaded à pay-bill, with Firefox (under ubuntu), in private navigation, and I get the file with a padlock-symbol at the end. What means that? What means that for me (on my computer), what means that for à friend, when I sent him the pdt-file (can he open it?). Nota: I understood that I can choose between "delete downloads when closing the privat window" or not. And I choosed not to delete them (but there appears this padlock-symbol). Thanks for your help! Michael from France

We are experiencing an ongoing issue with Firefox that persists even after performing the following troubleshooting steps: - Uninstalled Firefox completely. - Removed all browser add-ons and extensions. - Reinstalled the latest version of Firefox. Despite these steps, the issue still occurs: Browser crashes, pages not loading, extension not working. Additional Information: - Operating System: Windows 11 Pro - Firefox Version: 145.0.1 - Error Message:

We would appreciate guidance on resolving this problem, as standard troubleshooting has not resolved it.

Thank you in advance for your assistance. Kind regards, Edward

I recently got a new machine and loaded it with Linux Mint 21.3 - Cinnamon, FF 142.0 and Bitwarden Version: 2025.8.2 along with the usual cadre of extensions that I use on every other machine I have.

When I first start Firefox, Bitwarden autofill suggestions does not work, autofill from the "Fill" button in Bitwarden does not work and returns an error. The only thing that works is to individually and manually copy the username, paste it, then copy the password and paste it.

If I log out of Reddit and then try to log back in, the autofill suggestions works and the "Fill" button also works.

This is only on Firefox and only on the fresh start of the app. This does not occur on Chrome and I have not tried (and don't want to try) it on Windows.

For some days now the Guardian (UK journal) website can't be loaded. It's specific for Guardian, I have no such problems with other sites, and I don't have this problem with Guardian with Chrome. I've erased cookies and caches, restarted my computer, to no avail. I'm using version 146.6.0 of Firefox on MacBook Pro 2020 with Sequoia 15.7.1.

I recently wiped & reloaded my computer. Multi-Account containers re-installed successfully & I see all my containers. The issue is with sign-in to Reddit.com website. If I try to login using a container, I get invalid username or password error. If I login without using a container, it's fine. I am copy/pasting my account info. I tried different containers; same issue. Tried creating a new container; same issue. Try again without using a container; login to Reddit is successful.

its pretty much what it says on the tin, im not seeing my channel points in chat

 i have turned off all the tracking stuff 

i turned off the enhanced tracking and i still cannot see or earn my channel points i have turned my site security to nothing to see if that would do anything I have turned off all my add-ons and they just dont show can anyone tell me whats happening here

With Firefox 144, there is unasked for/unwanted AI introduced. How do I ensure that all AI is completely disabled in my browser? I found a link describing some settings, but want to confirm this will disable ALL AI in the browser. I don't want it, don't trust the privacy/security holes yet to be found and would prefer it was not included in Firefox to begin with. The list I've found is:

• user_pref("browser.ml.chat.enabled", false);
• user_pref("browser.ml.chat.menu", false);
• user_pref("browser.ml.chat.page", false);
• user_pref("browser.ml.chat.shortcuts", false);
• user_pref("browser.ml.chat.sidebar", false);
• user_pref("browser.ml.enable", false);
• user_pref("browser.ml.linkPreview.enabled", false);
• user_pref("browser.ml.linkPreview.optin", false);
• user_pref("browser.ml.modelHubRootUrl", "");

Will this do it? What about:

browser.ml.chat.nimbus

Do I need to clear that field to ensure I don't get some auto opt-in in the future as more and more of this "stuff" is put into the browser?

Why not leave Firefox as a security/privacy conscious browser and put out a separate AI browser (FirefoxML?) for those that are not as concerned. How does Mozilla ensure that no information is leaked through AI from sessions for professionals that must protect physician/patient, attorney/client information or other legally confidential information?

I get screen tearing on videos or when i scroll on any website. Only happens on Firefox, I've tested Chrome, Edge, Opera.

Smooth Scrolling is Off. Hardware Acceleration is Off. I've tried toggling "gfx.font_rendering.directwrite.force-enabled" Firefox is up to date.

None of this has helped.

Firefox is not saving my passwords. Every time I start up my laptop, all the saved passwords are gone. I have tried a refresh and a new install as well, but the problem persists. I have to sync to my other machine to restore them.

Below are two attached images, please take a look. From my understanding there are two different translation features built into firefox, you can identify them by looking at the attached screenshots. I very much dislike the translation features which has the "page icon". The other option which looks like an "alphabet icon" and has "EN" attached to it is very much welcome. I want to add this translation feature to the toolbar, however when i open up the "customize toolbar option" there is no translation feature available. How can i add it? I do remember that in previous firefox version, the translation feature was pinned to the very right of the bar.
