My system memory is reading at 57% right now in task manager, that the vast majority of that is being used by Firefox.

Why?

Normally, this would be called a flaw in the program, not the user, as all I have done in regards to settings is "keep tabs previous open when re-opening Firefox" and "Do not automatically update" because Firefox took it upon itself to not re-open my previous tabs on the last update.

Why is this program eating up all of that memory? I have "Firefox (15)" in Task manager under "Apps" and then 13 more instances of Firefox in "Backround Processes"

Wtf?

I currently can't stream anything, and this keep getting this message: Widevine Content Decryption Module provided by Google Inc. will be installed shortly,but it never installs.

I have a macbook air and am currently running macOS Sequoia version 15.0.1.

I tried uninstalling and reinstalling, removing extensions, clearing cache and data, unchecking and then checking back again the reproduce drm protected content but nothing has worked.

In Firefox, and only in Firefox, I get 'Failed to verify your identity' on these sites. I have updated MacOS and Firefox, rebooted, tried a different DNS, and disabled all of my extensions. With extensions disabled I don't get the error, but the login site won't accept my login at all. See the attached image. I can't think of anything else to try.

how to permit

This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection.

When I'm in full screen mode, The Apple, "Firefox" "File" "Edit" "View" "History" "Bookmarks" "Tools" etc menu bar shows up at the top and won't disappear. On my iMac Pro, it doesn't show up. i.e. Off.

I can't figure out what is the setting to make sure it does not appear. I went digging everywhere and can't figure it out. If you could tell me what config, etc I'm missing I'd appreciate it.

Screen shot attached to show which menu bar I mean.

My firefox is up to date: 126.0 (64-bit)

Sync is a nightmare. It is so unintuitive! What exactly would be wrong with having separate Export and Import buttons for each of Settings, Addons, Tabs, History, Bookmarks, etc? I have a desktop box and a newer laptop I wanted to get up to date. I pressed the Sync button on the desktop ... By the way, there`s a link below that reads "Connect another device" ... Connect where? Someone is designing these interfaces who has absolutely zero imagination. Anyways, I signed off, moved the ethernet cable to my laptop, signed in, pressed Sync, and voila!, I got my Bookmarks, at least. But I have no idea how to get my tabs and windows. I tried with a "download link" something or other, but it seemed to assume I was sync-ing to a phone, and didn`t work. Any way to get my tabs?

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

With Firefox 135.0 i cant reach google.com but google.se i can.

I make daily images of C: and today i managed to go back one day to 2025-02-06 but accidentally chooses 2025-01-06 and with the older version of firefox i could reach google.com

I have tried to delete cookies. DNS over HTTPS off. No proxy in connection. Add-ons off but to no avail.

Good day, The issues that I am encountering are explained below. The solution found after hours of research is uBlock Origin : https://ublockorigin.com/. Do you know which filters and rules should be applied to exclude the Wikimedia Foundation and all of its derivatives from the results provided by my search engine? Please share your knowledge. Sincerely. ________________________________________________________________________________________________________________________ I am utilizing Firefox ESR 128.10 desktop version on the Linux operating system. I wish to conduct research on the internet, utilizing the Startpage search engine. I would like to exclude the following sites from my search results: wikipedia.org, the Wikimedia Foundation, and any affiliated websites, regardless of the language or location settings configured.

What is the correct approach to establish a customized Startpage search profile excluding all Wikimedia Foundation sites? What is the proper setting to create a persistent and customized search engine configuration that excludes all Wikimedia Foundation domains even after an operating system update or reinstallation? Is it permitted to manually manage a customized search engine?

I have been advised to utilize an add-on or create a dedicated profile.

What would be the most suitable solution in my case, and the one that will be the most effective and stable ?

It is unfortunate that mozilla-firefox does not appear to offer a 'blacklist' or exclusion list feature, as that would be the most direct approach to excluding the Wikimedia Foundation websites from the search results.

I thank you kindly for all of your suggestions and responses to come. ______________________________________________________________________________________________________________________

I'm stetting up a testing environment. It's a closed environment with no access to the Internet when it's in use.

The environment is launched from AWS and consists of an Ubuntu 18 desktop and a Ubuntu Server running Apache. The desktop is able to successfully load the website, but with a cert error that the certificate isn't trusted.

When the Ubuntu Desktop launches, it has a fresh install of Firefox, and therefore all the directories in the users home folder are not yet setup for Firefox, including the database where the root CAs are stored.

I'm am able to add the Root CA certificate into the Firefox cert database AFTER the machine fully boots and I run Firefox for the first time. I'm using the 'certutil' package to do this. After I load Firefox, then add the root CA certificate using certutil, I'm able to load the website without error.

I need to add this certificate to the database with the startup shell script for the machine.

Any help is greatly appreciated. Here's the commands I'm using:

1. copy the CA cert into firefox

export ffcerts=`ls /home/testuser/.mozilla/firefox/ | grep default-release` sudo certutil -A -n "testcert" -t "TC,," -i /home/testuser/certificates/testcertCA.pem -d sql:/home/testuser/.mozilla/firefox/$ffcerts

These commands work perfectly after Firefox is run for the first time. I've even tried adding 'Firefox' (with several different switches) into my startup script without success.

I tried to log on this morning to my mail and get this link" https://guce.yahoo.com/consent?brandType" with a pop up page "oops something went wrong"

all searches I have done to try and resolve seem to be 2019 or older with the 2024 being locked.

I type in yahoo.com, do a search yahoo, they all come up the same message. anything yahoo related I cannot load. and get this same message.

I run malware byte and Ccleaner neither solved this issue

I use Microsoft edge and have no issues.

thank you

Every time I try to change the resolution of YouTube videos, it only provides 360p as an option, with a "Missing options?" message that redirects me to Google help page that just says my browser might be out of date (I'm on most recent Firefox and Windows 10 updates). The quality is still stuck in 360p when I reboot Firefox in Troubleshooting mode, and there are no quality issues when I use a browser like Edge. What should I be checking to resolve the issue?

There are 32 shortcuts on my home screen - 4 rows of 8 each. However, I accidentally "dismissed" one shortcut - now there are 31 total. I cannot figure out how to restore a shortcut. Is the solution in about:config (browser.newtabpage.pinned)?

I've added https://x.com as an exception site but it is still blocked.

https://x.com/mozilla doesn't work either

Error message on the page:

"Something went wrong, but don’t fret — let’s give it another shot.

⚠ Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com"

After 2 days it used to finally load without my doing anything, but not now. I never loads using Firefox.

https://x.com is added as an exception, but obviously ignored.

Tried You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

   hold down the Shift key and left-click the Reload button   

NOPE

Tried: Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings), click the padlock icon (Clear cookies and site data) for the domain in the selected tab.

"Remove the Cookies" for websites that cause problems:

   Settings -> Privacy & Security
   Cookies and Site Data: "Manage Data" 

"Clear the Cache":

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

NOPE - lost all my bookmarks, extensions, settings - not going there again thank you

as for:

You can check for issues with Enhanced Tracking Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

   click the shield icon for more detail and possibly disable the protection 

the sheild has a slash thru it saying "enhanced tracking is off for this site" when i put my mouse over it.

All of my addons are disabled and won't re-enable!

They all say "addon name" could not be verified for use in Nightly and has been disabled. See attachment clipboard00.jpg

If I try to install an addon from the recommended extensions settings (for example "return youtube dislike ") I get a message bubble stating "The Addon downloaded from this site could not be installed because it appears to be corrupt. {OK!}" See attachment clipboard01.jpg

The message above about addons appearing to be corrupt happens if I go to any of my current addon pages and try to redownload them.

Hi! I'm using Firefox 126.0 on Fedora 39.

Pages from Amazon.co.uk load very slowly, incompletely, or not at all. All other Web sites are fine.

I had a couple of certificate-related errors saying that the identity of the site couldn't be verified, but I can't reproduce the problem, so I can't quote the exact wording, I'm afraid.

The same Amazon pages load properly in Chrome on the same machine, and they load properly in Firefox in a VM on the same machine. That tells me network connectivity must be fine.

I've tried disabling all extensions, reverting to the default theme, running in Troubleshoot Mode, clearing cookies and site data, clearing the startup cache, disabling hardware acceleration, and creating a new profile. The new profile helps slightly, in that it loads more of the page before getting stuck. Nothing else helps at all.

I'd prefer not to refresh Firefox if I can avoid it, because I don't want to lose all my plugins and settings. This installation is five years old. Besides, a new profile didn't fix the problem.

What's the next thing to try? I'd really appreciate any ideas.

An hour ago I had all of my Firefox bookmarks. Ten years of meticulously filed and regularly culled references that I use multiple times daily. I rarely log out of Firefox sync, so that I can keep them up to date.

I now have no bookmarks and no tags.

For some context, two things just happened simultaneously. So, I'm not entirely sure which is the culprit.

1) Firefox just updated and I rebooted my computer.

2) Norton 360 updated sometime in the past two days. I attempted to familiarise myself with the new interface. Foolishly, given the track record of Norton-360-for-breaking-your-games, I ran the disc cleanup, which recommended I remove approximately 400 Mb of data. Norton stated this data was temporary files. If they were indeed my bookmark history, nowhere did Norton indicate they were bookmarks. Also, never have I encountered a disc cleanup that wholesale wipes bookmarks. I do hope Norton is not the culprit and this is just a glitch, because if this were due to Norton having no safety net for deleting an entire library of bookmarks - and they can't help me restore them - then that will be the final nail in the coffin for me doing business with Norton.

The suggestion to go to Import and Backup in Firefox, then click Restore, offers only the option of Choose file... - and then launches nothing.

Currently, I'm seeking any means of restoring my bookmarks. Any help would be appreciated.

I had presumed that I was taking reasonable measures through my Firefox Sync settings to protect my bookmarks and ensure they could be restored in the event of accidents. If these bookmarks are permanently lost, the amount of work I've just lost is quite the blow.

Edit No. 01: After writing this, my Bookmarks Toolbar is also now empty. Perhaps it had wiped earlier, but was merely waiting for a refresh to take effect.

Edit No. 02: Also, it seems I am unable to create any new bookmarks. I shall read the help suggestions relating to that now, to see if it's a relevant issue.

Hello, At one time I could login at home to view my Spectrum.net account on Firefox (default browser), now I get a popup which reads "This feature is currently unavailable. Please try again from home or contact us for assistance. "IDID-4000"

I get the same message on my laptop and desktop, both running Firefox. I can switch to the Edge browser and login with no issues. I have cleared cookies and used other suggestions I have read on the web, but to no avail. Any help would be appreciated!

Thanks! Tony
