Firefox 技術支援討論區

For the past few days, when I try to log on to PlayStation on Firefox, the sign-in page sits on a loading swirl after inputting email. There's a clear memory leak shown on Task Manager. The menu bar's right-click doesn't draw properly. FF can't be closed and needs to be terminated. The only extension I have is uBlock Origin disabled for this site.

This website works on Edge.

Attached is the broken menu from right-clicking the menu bar.

Hi there, I have configured Firefox to remove cookies after closing it. At the same time, I have added some webs that I usually use as exceptions, allowing to remember cookies in those. However, I have the following question: if I reject all cookies except for the mandatories ones in a website that I added to my "remember list", does that mean that future entrances in that web will be with only essential cookies?

As an example, if I mark https://www.bbc.com/ as cookies, and the first time I enter I reject all non-essential cookies, next times I enter in the bbc will I be navigating with only the cookies I accepted on this first entrance? Or allowing a site automatically accepts all cookies?

Thank you very much on advanced.

I accidentally hid the menu bar and toolbars (with an accidental keyboard shortcut, I think), and when I re-enabled them, now the tab bar is above the location bar instead of right above the content windows. How do I move it back? I can't find the "browser.tabs.onTop" setting in about:config, or any check box in the View menu, settings, etc.

I'm using Firefox 119.0.1 on Ubuntu Linux.

Thanks!

Hello, I recently used my MacBook Air to connect with a projector for a classroom presentation. The presentation was using Google Slides. I adjusted the settings to optimize the presentation--setting the navigation and bookmarks bars to hide when in full screen.

I normally use my Firefox browser in full screen mode, but have the navigation bar and tool bar visible.

I cannot figure out how to undo what I did so that my navigation bar and toolbar are visible again when I am in full screen mode. Indeed, when I move the pointer to the top of the screen to make the navigation bar and toolbar visible, I cannot move the pointer back to the navigation bar or toolbar without it disappearing again. Essentially, I need to undo full screen mode.

Thanks, jch

Hello there,

while trying to stream a Live-Stream i unfortunately get the following error, while the stream is loading: "Playback cannot continue. No available working or supported playlists."

Is anybody else encountering this issue?

Thanks in advance.

Sincerely

Dear Friends,

Trust all is well...

PLEEZE put an end to this mystery. Can you BLOCK YOUTUBE ADS or not? If so, how is that accomplished.

Many of the extension are not safe even dangerous to use.

Thank You!

Best, Ralph

My Windows Task Scheduler contains an entry called "Firefox Default Browser Agent". If I delete it, it returns. If I disable it, it re-enables itself. Can't be modified either. How do I turn it off permanently?

I already have telemetry and automatic updates both turned off.

In about:config default-browser-agent.enabled is set to false

For some reason my Firefox on my Mac and Windows computer won't sync even though I am using the same account. I would like my Mac to look the same as my Windows computer. I have tried logging in and logging out on both, all the basic fixes but nothing has helped.

Thanks.

I've been trying to export my bookmarks to an external hard drive so that if something should happen to my computer I have a file of them. I'm using Windows 11.

When I export the bookmarks as an HTML file, it saves OLD bookmarks from a few years ago, not the current ones. I know this because when I go to my external hard drive and click on the file and open it up it shows the old bookmarks.

I have no idea why this is happening. Can anyone help me? Thanks.

I decided to migrate from chrome to firefox, sadly, my experience has been faced with random slow downs or partial loads even on a fresh install. It's weird but it seems that at random times some websites will refuse to fully load or even start loading, it appears that the app is just hanging. This is usually fixed after several refreshes. Oddly enough, even on a fresh install, if I attempt to load up the same website while in private browsing, it loads right away, again this is consistent even on a fresh install, the attached image was an attempt to load youtube after signing in on a fresh install without add-ons, I tried loading up youtube in private and it worked right away. Chrome wasn't presenting this problem on my computer for years. Any ideas? My computer specs are high enough where they shouldn't matter. I'm running an AMD GPU (7900 XTX) but I haven't found any know issues regarding these, to even discard that, I disabled hardware acceleration, but the issue persisted. Running up to date windows 10, installing latest version of firefox.

In the Microsoft Store there are all these updates for video extensions like "AV1 Video Extension". Should I be doing these updates? Do they make any difference to streaming video on the Firefox Browser?

Hi all, I can not get Firefox to use my Microphone,

Apprantly Firefox updated last night. I still show all the names of my bookmarks but NONE of them have any information in them. Probably lost my passwords too.

Tried all the fixes shown in prior posts. This is unacceptable !

Hello,

I have tried many times to import my passwords from Chrome and from my desktop Firefox, using synchronising, to this laptop, and it has continually failed to happen. My Tabs and Bookmarks, for example, have all been successfully imported.

I want to make Firefox my default browser but cannot do this without successfully importing my passwords.

Please let me know what I should do next.

Are you able to take control of my laptop remotely and resolve the problem? If so, please let me know the times and days when you can do this, so that I can make an appointment, stating which time zone you are in as I am in England.

Many thanks, Michael

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD
