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

I have search separated from the url bar, and I have Firefox Suggest configured to only use history for tab completion. I've noticed a couple problems.

• Search is being prioritized over options in my history. I have the separate search box, if I wanted to search I would use it. If I type a single character I want the most common result from my history to be the result of hitting tab.
• I've noticed recently that I'm getting sponsored results even though I have them disabled. It's somewhat inconsistent, and I've only noticed it in one of my profiles. Specifically I am used to "w <tab>" taking me to weather.gov but I'm getting sponsored results for AccuWeather. I clicked the "feedback -> not interested" button but this is concerning that Firefox is ignoring preferences and there's a pattern of sending data to Google and AccuWeather despite me configuring the browser not to.

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

I moved to Firefox because I have autism and someone told me it would help block the popups and moving content that makes using the web exhausting and difficult. And it does!

The trouble is, it replaces them with something worse – a grey screen that rolls continuously from left to right. It's impossible to focus on text with such intrusive visual distraction, so I have to shut the page down. It seems to occur on so many websites that at the moment it's not worth trying to use the browser.

Half the problem is that I don't know the right term to describe it, which makes troubleshooting a bit complicated. Hopefully someone will recognise it from the description, though – if so, is there any way of stop it moving, please?

Thank you!

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

my browser continues to show symbols instead of words. I troubleshot the font issue and it does not seem to be that. this is on a macbook pro and the browser is updated. I deleted the browser and reinstalled it. which worked for a day but then everything went back to showing symbols. it is intermittent in that sometimes it will show the real words and then a few hours later is will show this.

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?

I am using Firefox version 119.0.1 (64-bit) on Ubuntu 22.04. Using this version of Firefox, as well as previous versions for the last few months, I am having a persistent error when using Google Advanced Search. I enter search criteria into the field “Find pages with … all these words” and successfully progress through a chain of web pages. Previously I was able to backtrack to the previously mentioned field and find my search criteria, then edit the text, and carry out a modified search. For many months this field has been blank when returning to it. So it is now necessary to re-enter all text for a new search. This is very frustrating. I have experienced this problem on the three computers that I regularly use.

I have found that when I use the Google Chrome browser the problem goes away and searches progress normally. I would much prefer to use Firefox as my browser as I find its bookmark system superior. The truth is that if this problem with Firefox can’t be fixed soon I will be forced to migrate to Chrome. Can you please help me resolve this Firefox problem?

Wanted to export some bookmarks, and couldn't figure out why (latest Firefox) Bookmarks "Library" was missing relevant buttons/menus. (Screenshots attached.)

After testing, found they actually are there, but have have almost no contrast vs background - that is when "Manage Bookmarks" is called from a Private window. But things look fine when called from a Standard window. (No extensions; same in Safe Mode.)

Can anyone advise?

A simple workaround is to bring a standard window to the front first, but am curious if this is Firefox on all systems? Only FF Linux? Only the particular (default) settings of my Linux Mint 20.3 Cinnamon installation, and display? Not even sure a Bookmark management window is ever meant to assume the theme of the foreground window (here Private browsing's dark).

Thank you.

This is the link that Fox was reporting difficulties playing on a Mac running Firefox. I just ran it on my ancient imac using an older LTS version of firefox and am not having any problems (nor with chrome)-

Contacted Specrum Customer Service because I couldn't login to my account. Rep told me it was a browser issue and suggested I try a different browser. I did so and was able to successfully log in to the Spectrum Site. What do you thing is the problem with Firefox and the Spectrum site? Everything else I log in to works fine.

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?

Dear Firefox Community,

my ff browser won't open the following websites:

https://www.haaretz.com/ (here it says: Error 54113) and https://archive.ph/ (this won't open at all without any notification)

Could you please let me know how get them to open?

Thank you!

I can't find any way to group windows. Yes, "windows".

I have about three dozen windows open (yes, there are a lot of tabs in them), and not just at home. And it’s hard to quickly find your bearings when you need to switch to another task (workspace). It would be nice to at least change the color of the windows, depending on the type of work. But in the API API I don’t see the ability to define a window property where you can specify a group identifier, which can be used to restore the color after re-opening FireFox.

If FireFox had a built-in or its own reliable extension for organizing thematic work, a deferred workspace (without losing the contents of windows). Arc browser - they realized that what browsers have been denying for a decade is already overdue, and they will be able to take over the market.

I tried several extensions for saving, restoring and organizing workspaces, and came to a clear conclusion: only the built-in FireFox solution for restoring windows after a crash/opening is the only truly reliable solution. There is no trust in extensions that are not supervised by a good team of developers and testers; there is a guarantee that data will be lost in the near future.

It is possible that in recent years some expansions have been completed. I'd be glad to know about it if you point it out. But here a question arises on a separate topic: improving the mechanism for rating and testing extensions, recommended extensions program.

I'm a newbe Thunderbird user making the transition from Outlook which I've used for years but recently discovered is too compromising especially when it comes to archiving. Have been using Mozilla for years on a Surface laptop (windows 11), Cyberpower desktop (windows 10), and Android Note 20. I've downloaded Thunderbird and it is working fine. Where can I find user training videos for Thundbird, especially archiving? Are there other ways besides on-line gifting in which I can contribute to the research that makes Mozilla and Thunderbird possible? Thank you.

I'm using Firefox for Windows and usually have a few set pages that appear every time I open a new window. Every now and again, I have to add, remove, or change one of these pages. The issue is that I have to see something like this whenever I want to change anything.

`https://link1.url.com/|https://link2.url.com/|https://link3.url.com/|https://link4.url.com/|https://link5.url.com/`

Naturally, whenever I open a new window in Firefox, this is automatically interpreted to open multiple pages. However, this way of displaying them is still inconvenient. I want to know if we can get something more like this.

https://link1.url.com/ https://link2.url.com/ https://link3.url.com/ https://link4.url.com/ https://link5.url.com/

Is there a way to edit the Settings UI to see a multi-line list with the ability to add, remove, or change these links individually? Thank you.
