outrageous, i moved from windows to debian for the purpose of exceling my ram capacity on this low spec netbook with 4GB 3.7GB usable with emmc chip and a celeron n4000 cpu turns out ff eats just like in windows.

I am not an expert just savy, remember the time when upgrading from 32MB to 64MB was a big leap? well where the hell did 4GB of ram became obsolete? so there's no windows conspiracy just exponential ram usage?

Is there a different version of FF i could use for this 4GB machine? non-upgradable I could always try vivaldi or look else where but i trust FF for base security. I am using ublock origin on the machine too and 1 custom theme but i doubt that fixes the root cause. Is all the internet in the 2020s this ram voracious beast?

upon loading a empty tab FF uses 500MB for itself forget about the 64MB system ram from the 90s is FF 2025 really so complex or is this a conspiracy? then i load startpage.com and it uses 200MB!! of ram just on that search form man.

Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

If you have questions about the update or need help with the process, this is the place to ask! Whether you’re just starting or you’ve already updated and want to share your experience, we’d love to hear from you.

I prefer to use Startpage as my search engine with Firefox on my Mac. I have that set up, but it's so annoying that when I put something in the address or search bar, no search happens. Instead, I just get the Startpage home page and then have to retype the same thing in there! How do I solve this?

The search bar covers the bookmarks bar when hovering over the top on Mac. It needs to be so both the search bar and bookmarks bar move down when you hover over the main menu settings in Mac.

Hi friends.

As shown in the image, if I enable "Address Bar - (suggest) Browsing history" option at about:preferences#search page, bunch of subordinate pages are displayed, which is barely useful, in my opinion.

I want to hide them, but I want to keep the auto completion functioning. For instance: I want my Firefox to complete https://youtube.com/ with only typing y, but don't want to see those 'Firefox Suggestion' pages.

Is it possible to set it this way? Or I can't just have it both ways? Please let me know.

(Thanks in advance, and responses in easy English will be much appreciated; I'm a beginner in English.)

DO NOT COPY AND PASTE! This is not written correctly! Someone please help with this or correct the code. I tried different ways to do this and nothing works ---- I am beyond frustrated with it.

Security features warning

You may see a warning that “some of Firefox’s security features may offer less protection on your current operating system”.

The sandbox in Firefox makes use of unprivileged user namespaces when creating new processes for enforcing more security. This can be considered a security risk, therefore some Linux distributions have started to restrict its usage and only allow it to work where there is an AppArmor profile.

Such profiles can only cover a limited set of installations paths, including Snap and Debian packages. They cannot however cover some other use cases, such as tarball installations as well as local development builds.

To create an AppArmor profile for Firefox:

In /etc/apparmor.d/, create a file with the name firefox-local

In the file, add the following:

1. This profile allows everything and only exists to give the
2. application a name instead of having the label "unconfined"

abi <abi/4.0>, include <tunables/global> profile firefox-local /home/<USER>/bin/firefox/{firefox,firefox-bin,updater} flags=(unconfined) {

   userns,
   # Site-specific additions and overrides. See local/README for details.
   include if exists <local/firefox>

}

Replace <USER> with your Linux user name. This assumes the Firefox install is at $HOME/bin/

Once you have saved the file, run sudo systemctl restart apparmor.service in the Linux terminal.

Dear Mozilla,

Yesterday I successfully installed my [edited] @ledgreenus.com email on my desktop computer, but today I have no way to access it. I don't understand how it can be hidden like that. I can't do it on my cell phone either. Please help!

My computer is a mac running OS X Yosemite. When I tried to update I got a message saying that the update was not compatible (My operating system is too old?) I had to reset back to an earlier version of Firefox. Is there some way I can make an update that will allow me to keep using Firefox on my machine?

My Firefox browser has ceased working on my Mac Mini (OS X 10.10.5) - have tried several update downloads, all coming back with the message that I cannot update the browser due to the OS I have. What is my next step? Have I lost Firefox as a browser? Suggestions?

Can you add a configuration setting to Mozilla Firefox to disable Create New Profile, configurable in the policies.json file? (A second option but a much uglier one would be to disable being able to select a file location for a new profile. Then you could make the default profile directory write only, which would also accomplish the same thing.) (A third option would be to able to configure extensions by default upon installation in the ExtensionSettings policy.)

To explain, I use LeechblockNG on Firefox on Ubuntu. Very helpful. By placing a policies.json file (see at bottom) in /etc/firefox/policies/ directory, I can create a system wide policy. I can make the LeechblockNG extension mandatory and to be installed upon every new profile creation. That all works very well. HOWEVER, there is NO way to be able to set those options in the new profile. So LeechblockNG is installed with default options (which are no blocking at all), which effectively bypasses the addon.

I am also writing the author of the leechblock extension to see if there is any way to set the options for leechblock upon installation (the third option above).

But I know other people have this same question, and at present, if I am correct, there is no way to block new profile creation, or the Profile Manager window in Firefox.

So could you please add that option to the Firefox policies.json configuration? Something like "DisableNewProfiles": true would do it.

Thanks!

My current policies.json file in /etc/firefox/policies/ directory: { "policies": { "BlockAboutConfig": true, "BlockAboutProfiles": true, "PrivateBrowsingModeAvailability": 1, "DisableSafeMode": true, "ExtensionSettings":{ "*": { "installation_mode": "blocked", "blocked_install_message": "Prohibited install more extensions." }, "leechblockng@proginosko.com": { "installation_mode": "force_installed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/4374316/leechblock_ng-1.6.6.xpi" } } } }

Greetings all, my trusty Firefox stopped working. Error Code PR_Connect_reset_error. Other browsers work fine. I have windows 10 with the latest updates and use Kaspersky Internet Security 21.3.10.391 (m). I have paused Kaspersky, uninstalled then reinstalled Firefox 3 times. I have cleared all Firefox cookies and caches a number of times. On my 2nd Firefox reinstallation Firefox worked ok for a couple of times then stopped again with the same error code. Please note that I am not very familiar with computer stuff so any suggestions need baby steps. Many thanks.
