Firefox 技術支援討論區

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

Recently have been unable to access the USPS Website from any of my Firefox Browsers. Firefox displays the following Message:

You do not have permission to access this page If you have found this page in error, please contact support Reference:10593116689666961403465577003670526342620034968299102359

Was getting some crash reports....now have a black bar on top of new tabs...it finally scrolls when you are halfway down the page. any help would be appreciated.

Firefox bookmarks exported from old Windows PC to html file. File transferred to new Windows PC and imported into Firefox. 'Bookmarks Imported Successfully' message seen. However no bookmarks visible in Firefox bookmark menu. Suggestions please?

when i have any of those 2 flags set to true it opens all links i middle click from firefox-view history all the way to left since firefox-view isn't a tab. I'd rather have it force them all to the right by default instead of it thinking i am not in a tab and have no tabs open

I have a subscription to Global Cycling Network, to which I login using my Google account at https://plus.globalcyclingnetwork.com/login. The login web page has options to login using Google, Facebook, or Apple, but in a normal Firefox window, the buttons for using these logins never appear - I just get a whirling circle where the buttons should appear, and the page never completes loading. If I open the GCN login web page in a private FF window, the buttons appear and I can login without any problem. If I use Firefox Settings to clear all cookies and cached web data, then close and restart Firefox, I still can't login from a normal FF window.

I tried the Edge browser (OS is Windows 11) and login there works without problem

Any suggestions on a fix to get it working on Firefox? FF is presently version 119.0.1.

My LastPass extension appears as a black box with an elipse. It is red when it is active. I have logged in to LastPass, and when I go to the extensions icon and select "Open Extension" nothing happens. It's not filling in any of my login information.

Why is this so difficult? I keep getting the attachment. How do I stop it? I NEVER WANT FIREFOX TO TELL ME THERE IS AN UPDATE. I will check and update when I'm ready. How do I stop this?

In error, I answered 'yes' to save an entry on a site to be my new login ID & pswd for that site. I want to get back to my original login ID & pswd. They told me I need to call my Browser FireFox to "get rid of my pre-saved login id & pswd". How do I do that? jerrybrown411@gmail.com

Firefox not responding to general websites on the web (Ex: Amazon.com, etc.). I have several Mozilla-recommended security extensions that may be working against my firefox connecting to these general-in-nature websites.

During my absence my house maid created a Google account for herself on my Firefox browser, which is confusing my browsing as it is also a default account. I wish to remove my maid's account but cannot find how. Please help. I am using Windows 10.

I was using Lightspeed today, and the website pops up a confirmation dialog box (probably through JavaScript) so that you can confirm that you want to do a specific action. I got annoyed with the dialog and clicked the included "Don't allow this website to show prompts anymore" box when I hit OK. But now it won't perform any action that requires you to hit the OK in the prompt, so I need to make the dialogs come back so I can do my job. I can't find any setting anywhere in the browser that I have actually disabled or changed by hitting the box in that prompt.

I am not able to navigate websites per the ADA Accessibility requirements using my FireFox browser. I have tested the same websites in Chrome and the TAB key is working correctly, but in my instance of Firefox it does not. I have a colleague who tested the same website in their Firefox browser and they are not experiencing a problem navigating the website using their keyboard TAB key.

I am on a Mac with most recent FF installed. Colleague was on a PC and tested in FF.

How can I get FF to work correctly on my Mac?
