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

Please return the scroll bar to the proper width like in Win 10, like Chrome in Win 11. Who's the idiot that thinks tiny thin scroll bars are cool and easy to use? tf is wrong with you idiots. Don't offer me solutions. You are the solution. Update firefox, fix the damn scroll bar.

New computer (Windows 11) shows 'Old Firefox Data'. Opened hidden files. Using File Explorer found Profile Folder & renamed it 'old'. Copied and pasted 'Old Firefox Data' as new profile. Firefox would not open. Had to remove etc and Firefox worked again. Thought this maybe the easiest way to get my Bookmarks back.

PS Presume Profile Folder does not contain Thunderbird Addresses?

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.

Firefox browser problem. When dragging the mouse over text on a webpage to select text I want to copy, some of the selected text and an area of webpage adjacent to the text I'm trying to select is blocked by a box that automatically appears. Sometimes it whites-out a box-shape but usually it's blacks-out. This blocks that part of the page and some of the text I'm trying to select while I'm dragging my mouse and I can't see the mouse while I'm trying to select text within that box. What did I do to cause this and can I change something to make it stop? This is only when using Firefox and I didn't have this issue until October 2023.

My extension is greyed out in the Extensions drop down. I have redeployed it in the Mozilla Developer Hub but to no effect. It has been down for a couple of days. What could be the reason behind it and how can I fix it?

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.

Hello,

I have reinstalled fresh firefox for like the 5th time now. It continues to not load web site pages completely. One other example, I log in to yahoo mail the page loads. I then click on the mail icon to go to the mail and NOTHING happens.

This is getting old. It only happens with firefox and not MS Edge.

anytime I type www into the URL window firefox autopopulates youtube.com even though I have turned off auto suggestion. It shows up before the bookmarked links !

it always automatically checks the "Search suggestions ahead of address bar results" and will not let me uncheck it.

I just dont want it to suggest anything and am okay typing the complete URL. How can I fix this issue? I am including snapshot of what the autosuggestion, settings and version info in the attached doc

Hello! Since updating to the last version (119.0.1), Firefox started keeping my open tabs between sessions. This is a behavior I don't want, and the only solution that I found told me to enable "clear history on close", however that is also not ideal, because I don't want to clear my history. The "Open previous windows and tabs" setting is off and my homepage is set to Firefox Default. I don't know where else to look for such a setting, except in the about:config, but even there I'm not sure which one is causing the issue. Any assistance would be appreciated.

Windows 10 Pro 21H2, Firefox 119.0.1

With increasing frequency, when I open Yahoo in Firefox, there are no photos on the site and I can't access my email. In order to fix this, I have to shut off my computer and do a clean reboot. Then it works for a while, but then, all of a sudden I have the problem again. When I use a different browser (Chrome, Edge), I never have this problem. I thought it was Ghostery that was interfering, because Ghostery does screen out a lot of stuff, so I turned Ghostery off. It made no difference. What solution do you have to offer for this problem? I really don't want to switch to Chrome or Edge, because Firefox's general user interface is so far superior, but the issue I have described is a serious one. (There are two or three other websites that also don't work with Firefox when it comes to user doing data input on the site, but I'll be sending a separate inquiry on that).

Thank you, Alan Rosenbaum

Hi all,

Using: Firefox 119.0.1 (64-bit) on Windows 10.

I seem to having an issue with adding search shortcuts on FF, I am following this guide:

https://support.mozilla.org/en-US/kb/assign-shortcuts-search-engines

But I'm stuck at step #4 as the table seems to be disabled.

This is a personal laptop and has not policies on it.

Thanks for your time and assistance!

Hello. I have 2 Other Bookmarks Folders. One near the top under the Bookmarks Toolbar & one at the bottom. They seem to have the same folders & bookmarks. I'd like to delete one, but I'm apprehensive about that because I think I would end up deleting both of them.

Any suggestions. Why do I have two? Thanks In Advance, Carol

A tab for the Etsy website automatically appears every time FF starts up. How to stop this?

Just began after using the site a couple of times, but I did not indicate or click a setting on the Etsy site to ask for this.

All solution suggestions seem to be for pop-up ads, and don't work to block a website. Is there a way to block this?
