Firefox 社群討論區

Hey there Mozilla team, Love the new free built-in VPN for the browser and Kit. :D But I have problems with enabling the VPN. I am on Linux Kubuntu and the VPN cannot start. Funnily enough when i turn on Mozilla VPN on device level the Browser VPN does manage the enable itself.

Also I have a question about the Mozilla VPN browser extension. Is support for Linux still being worked on? And could we see the support being implemented soon?

Have a wonderful Day

Previously, had no problem loading YouTube videos in multiple tabs, switching between them and them playing their videos with no freezing , pausing or buffering. Since the last upgrade loading a single YouTube video causes it to freeze and continually buffer. And Firefox is spawning multile copies of itself in task manager. (One instance had 15 copies.)

Why my mozilla account didn't save my bookmark correctly, I just upgrade my windows to Windows 11, before I install my OS, I already syinced my Mozilla Account and all its data include bookmark toolbar. But, when I try to login and resync all my old data, its all gone, how to solve this issue?

I'd like to know how to hide the previews for vertical tabs in Firefox. I've already unchecked the "Show preview image when hovering over tabs" option in the settings. Is it impossible to hide them?

pourquoi "acheter" AdBlock puisqu'elle est proposée gratuitement? a ma connaissance c'est la seule extension Firefox à me proposer une contribution payante. Je refuse of course!

I just lost my bookmarks again, it happened a month or so ago as well. Appears to have been due to updates.

I have already followed the recommended ideas of navigating to restore, but there is no date given to restore to.

Just "choose a file comes" up, and that appears to lead nowhere.

I also went about:profiles , and all that was there was the current "cannot be deleted " profile and the option to make a new one, I tried that, it did not restore bookmarks. I need some of tose bookmarks quite badly this time

What more can I do ?

I Loged In To My Firefox Account Today Done My Work and Close the Browser and Shutdown The Computer. On next Day When Again I On My Computer And Open Firefox The Firefox Account Gets Logged Out. I Am Facing This Issue From Long Time. I Want It Shoud Be Logged In and Only Loged Out When I Do. Plese Help Me Out.

First off - love Mozilla's work, thank you all for your efforts!

The problem: I f'd up with the Profiles option. I wanted to set up a Work profile on a new windows laptop associated with a new work email (msta....), and then separately have my personal profile connected to my gmail (mstn...).

Well somehow I managed to make my Work (default) profile connected to my overall Firefox + Google personal profile, and have spent a month in my ignorance saving away settings and bookmarks on this machine. Is there anyway that I can disconnect my Gmail account from the profile Work, and connect it to the secondary profile on the same machine titled 'Mel'? Or will I need to export the last month of bookmarks, implode my Mozilla install on this machine, and start over with new profiles and better practices?

Help, multipass!

Thanks, Mel

I'm using Firefox esr, the latest version 149.0.2. Since this update, I can no longer load the videos on NPR.org's home page. Something pops up, but then the wheel/circle thingie just goes round and round, and never loads the video.

My ad blocker was already off for this site. I've tried restarting Firefox in Troubleshooting mode, and changing the various security settings mentioned in this article: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings, such as adding it to the "Allow popups" exceptions (never necessary before) and other settings. I've reloaded the page multiple times, restarted Firefox, etc.

Can anyone suggest anything else to try?

Relevant to Firefox running on Ubuntu 22.04 Linux and an x86_64 platform.

Until roughly 2/2026, it was possible to load a security device by opening Settings, Privacy and Security, Security Devices, then browsing to a shared pkcs11 shared library, in my case /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so, and clicking Load. The shared library would load and would be loaded subsequently whenever Firefox was started. For roughly the last two months, Firefox would pop up an error saying it was not possible to load the security device, but it would actually be loaded and it;s functionality would be available for the current session. For the last two weeks, the library would load without error, but only for the current session. Starting on 4/13/2026, some functions in opensc-pkcs11.so work, but not others. For example, it is no longer possible to connect to MS Teams web interface.

I don't really want to disable storage or ALL cookies. But I DO want to COMPLETELY sanitize on shutdown. While this policy is effective AND network.cookie.noPersistentStorage in config has been set True, NEITHER stops Persistent Storage nor cleans it. ONLY manual cleaning (deletion) of persistent storage is available in Settings: Privacy & Security: Manage browsing data. There is no other option available that I can find. One solution suggested a setting that both disallowed cross-site cookies AND isolate other cross-site data but there is no setting like that. There are TWO separate settings for that. Besides, that is not what is wanted.

How can I either completely disable persistent storage - or, more preferred is to completely clear persistent storage upon quitting?!

I have everything else cleared on quitting but persistent storage is indeed persistent. If I have to, I will disable it completely (not preferred) but do NOT want to disable ALL storage use.

Why doesn't network.cookie.noPersistentStorage not work? Or, if it does, what does it actually do?

I would like a policies.json entry for this as I already employ the file in /etc/firefox/policies as described. This is the preferred method for multiple users.

I am using Ubuntu and Firefox Snap for Ubuntu 149.0.2 (64-bit). Let me know if other information is needed. Thank you.

HI i have an ASUS-VivoBook laptop that has an intel i5 10th gen and geforce mx250 with 8gb ddr4 ram when i use firefox it uses about 550 mb ram alone on one page only is that supposed to happen ? if not how can i reduce my ram usage and power usage from settings and thank you for this amazing web browser i realy like the animated castle town from deltarune theme i am never going back to chrome THANKS ALOT

When opening websites the images are not opening, only blank boxes appear. I don't have any settings for security causing problems because I turned them off previously. simply cannot find what is driving this. Thanks, Don
