Firefox 技術支援討論區

I recently performed a system reset and upon re downloading Firefox I can't seem to find any of my 50+ tabs that I had open previously, all of them I need for one reason or another, history is empty, can anyone please help explain how to get them back in simple steps?

Please let me know what is wrong here I have recorded the issue as you can see that the buttons of pop up for screen record are missing text also location pop up is missing text same with download file names.

I don't know what is the issue and why the texts are not showing but it's been a big hassle.

Please help me solve it. I barely managed to record thing since even it doesn't show which screen I want to record.

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

As of yesterday when I was running v119.0 I was able to screen capture streaming content from Hulu/Netflix etc, this morning after upgrading to v120.0 overnight, that capability is now lost. Video and still captures are just a black screen. Please fix!

On FF 120.0.1 and Tab Reloader 0.6.1

I have FF set up with 7 tabs as home page, 6 of the tabs have tab reloader set to reload ever 1 hour. This has worked fine for years, the tab reload for the 6 tabs were saved after restarting FF. I didn't have to go back and tell tab reloader to reload after restarting FF. Maybe once and a while one tab didn't get the reload saved on a restart, usually always the same one.

Now when I restart FF none of the tabs have saved the setting to reload every 1 hour.

This has been going on for the last 2 releases of FF updates and there hasn't been any updates for tab reloader. Does anyone know why this is happening, I haven't changed anything in settings. I did uncheck hardware acceleration to see if that would fix another issue, but tabs weren't reloading after restart prior to that change on hardware accelation.

Many complex websites that had no problem till the latest version of Firefox don't load any more with the newest version. If this goes on like this I have to change my browser. I used Firefox now for many years but it looks like I have to change, as there are no problems with other web browsers (Opera, Edge, Chrome, etc).

Aren't there a lot of feedbacks like mine?

SIncerely, Franz

Hi,

It hard to explain what I mean so I recorded video, link is below. I want Firefox to behaves the same as Chrome. So as you can see, when I use address field for quick search then pop-up appears with search results. And I click on these search results with middle mouse button. But on Chrome it works normally and on Firefox not. I am redirected to just opened tab what is really annoying. I must go back, input the same if I want open several result. How to change this behaviour to achieve the same what I have in Chrome?

Chrome Firefox Serach Behaviour

Also it’s exactly the same when it comes to bookmarked pages in a folder on the bookmark bar. When we click folder with bookmarks we have dropdown menu with bookmarked web pages from this folder. And when I click something with middle mouse button then page opens in new tab but this dropdown menu disappears, and again I must click folder when I want open more sites. In chrome it doesn’t. How to set it the same for this?

I use to be able to work on one app/window and hover over multiple tabs to obtain brief details on the browser (tabs) as it sits behind the app/window I'm currently working on. Since about a week ago, this feature has gone away. Now I have to be on the browser to be able to hover over the tabs to obtain the info I need on the tabs. I do this to compare the order # that displays on the tabs for what I use it for. How do I get this feature back. I want to be able to hover over tabs to view the small details even when not currently on the browser itself. Please help.

I use Firefox for Mac. Often when I want to click on a link or complete an on-line form, a long list of unwanted suggestions pops up and orevents me doing this. Only by hitting Escape can I get control back.

By the way, I don't want any solution which involves clearing the cache, as I value that help.

I'm using Firefox on a Fedora system. As shown in the picture, the first Firefox Project below the address bar is pinned there. I searched and searched in the settings, but still couldn't find a way to remove it. I didn’t pin this address myself. Firefox on Fedora did it itself. In time, I switched to Firefox on the Windows, and after logging in to the account, it also synced out.

I use photopea.com for photo editing and stuff, but I accidentally clicked on the option to have that site not show a pop-up asking if I'm sure I want to leave the site and asking if I'm sure I want to close a project. Now I can't close projects at all.

Can someone tell me how I can re-enable it for the website?

We write an SDK that needs to detect what subdomain a site is running on. For example to detect that app.foo.example.com.au and web.foo.example.com.au share example.com.au

In order to do that we check if we can set a cookie on `.au` that fails. Then `.com.au` also fails, then `example.com.au` and that succeeds

This is safe and fast and leaks no information not already available to any JS running in the page.

In most browsers this is fine. In Firefox it is also fine _except_ it logs a warning to the console that a cookie was rejected. This then causes users to open a support ticket with us in order to find out about "the error"

Is it possible for us to suppress this log?

Hi,

i want to autoupdate firefox silently on a bunch of servers. When the mentioned settings are in place i'm still promted to update firefox when opening it. This isn't possible for the users as this is something a systemengineer should do. Is there anything i'm missing for a silent autoupdate? There is no JSON file in place. these settings have been distributed by a GPO.

Kind regards,

Remco

Embedded links in Outlook email on Windows 10 will not open automatically when the new email is first opened to be read if Firefox has been selected as the default Browser. This is a new issue !

The message is" if there are problems with how this message is displayed, click HERE to view it in a web browser " and then the Browser used is only Edge!

Restoring disliked Edge to be the default browser corrects the issue but Edge is a known tracking device.

Hi,

I'm getting errors when trying to make online card payments with Firefox. Things like, Invalid card number, not being able to type number in box provided, (No Cursor). It works ok on some sites but not others. However, if I switch to the Edge browser all transactions work perfectly. This has been happening for some time (Windows 11). I'm thinking this could be a bug but not sure.

When viewing any tiktok account profile page, for example this one , the videos do not show up, and says "Something went wrong, Sorry about that! Please try again later."

Here's what i did:

1. Created new Firefox profile with default settings and no extensions
2. Visited a TikTok profile, and saw it opens as expected
3. Changed privacy.resistFingerprinting to true
4. Refreshed the TikTok profile page, and the error message shows up

I opened the console and compared and there were new warnings:

• Blocked https://www.tiktok.com/@tiktok from extracting canvas data because no user input was detected.
• Get user detail failed for getting wrong response

And 3 errors, when there were 0 before, all three read

• Uncaught TypeError: _0x5e9eb8[_0x2bd187] is null
