On the page listing passwords, it was possible to sort them by "Alerts".

In settings, there is an option to enable checking the vulnerable passwords: https://support.mozilla.org/en-US/kb/firefox-password-manager-alerts-breached-websites

On my other laptop using Firefox v121, the alerts are properly displayed. But on my second laptop using Firefox v124, the alerts are gone. I can't sort password by "Alerts", the option isn't there. Both laptops share the same Firefox account and have password synchronized between each other.

Obviously, I ticked the "Show alerts about passwords for breached websites" box in the settings but it looks like it does not nothing. I also checked in "about:config" and everything seems good.

Is this feature gone?

Dzień dobry, W mojej przeglądarce chciałabym skorzystać z czatu GPT, ale pojawia się komunikat, że żeby skorzystać muszę wyłączyć blokadę reklam. Szukałam takiego czegoś w ustawieniach i firefox support, ale nie znalazłam nic co by pomogło w wyłączeniu blokady reklam. Czy mógłby mi ktoś pomóc i pokierować jak mogłabym wyłączyć blokadę reklam? Jeśli tak, byłabym wdzięczna.

Proszę o szybką odpowiedź

Hi,

We have an application where we do not want to share the session cookies between tabs. Is this possible? If above answer is yes, next we would like to filter out some cookies by name that should not be shared across tabs. Meaning, we want some cookies that can be shared across tabs and some should not be shared.

Thanks in advance

Hi, I did a clean install from win10 to win11, then installed firefox and logged in to my account but it havent synced anything? All my saved passwords and bookmarks are gone!?

Can someone please help me get them back! Does anyone have a solution for this?

Read something about that a backup is saved on your computer? Isnt saved to a cloud? Thats what a thought! I have done a clean install on a new drive, old drive i already wiped aswell! Doesnt have a windows.old dir or anything.

Please tell me everything isnt lost!

Best regards Gabriel

Whenever I get a link whether in an email from a verified sender or from using a site like Amazon, clicking on a link always results in "Hmm. We’re having trouble finding that site." This has happened ever since loading the most recent version of Firefox (124.0.2) and it is very, very frustrating. What is causing this? Even in "safe" mode this occurs. Please rectify this situation. I do not want to have to change browsers after more than 20 years with Firefox.

remove ad blockers even though I already have removed them.

printer is not recognized as being online although my other devices don't have the problem. i use Firefox on all devices

I have 3 laptops all running windows 10 or 11. These all share a docking station giving access to an extended display, keyboard etc. All laptops run fine with the docking station except for one issue with the newest laptop... The screen resolution, only on firefox on the one laptop, (everything else is fine) is completly out of whack. I have tried the zoom function but no luck. I have trawled the internet but all the solutions are from 10+ years ago and refer to different versions of firefox and windows. I am not a computer geek so please dumb down any advice.

Starting a couple of weeks ago, I began noticing that occasionally (every 2-3 days usually), a few empty files appear in my c:\ folder (Windows 10, as up-to-date as Windows ever is). They have names like "wal3A7109C6" (no file extension). Usually 4-5 will be generated at the same time (ie, same timestamp, so within the same second).

When I first noticed them, I (nervously) deleted a batch with no apparent consequences - but I had to activate Administrator privileges to get rid of them. I ran virus scans but have seen nothing unusual.

A few minutes ago, I had Firefox open but minimized to the task bar. I also happened to have c:\ open in a Window I could see. As I tapped to expand the browser, another of the files appeared, and the browser window behaved oddly for a moment, as though about to crash. The last few versions - I'm at 125.0.3 (64 bit) - have been crashing more than I'm accustomed to, but this is the first time I'd considered the browser to be a likely suspect.

Does anyone have any clues/possibilities to offer? It would be much appreciated.

Opened a directory of pdfs from the command line using ```firefox * &``` and went on with my work. Checked the terminal to see these error messages: ``` [Child 19416, MediaDecoderStateMachine #1] WARNING: Decoder=7f6e75431700 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005): file /builddir/build/BUILD/firefox-125.0.2/dom/media/MediaDecoderStateMachineBase.cpp:167 [Child 19416, MediaDecoderStateMachine #1] WARNING: Decoder=7f6e79a87a00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005): file /builddir/build/BUILD/firefox-125.0.2/dom/media/MediaDecoderStateMachineBase.cpp:167 [Child 19416, MediaDecoderStateMachine #1] WARNING: Decoder=7f6e84e52400 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005): file /builddir/build/BUILD/firefox-125.0.2/dom/media/MediaDecoderStateMachineBase.cpp:167 ``` I tried recreating this error by restarting the entire process and repeating everything, but to no avail. I'll try to recreate the error a few more times, however if I don't post a message it means I was unsuccessful.

Hi thanks for clicking.

I'm on Linux, Zorin OS, which is Ubuntu based if I'm not mistaken, very new to Linux.

Anyway, I've made a userChrome.css and done some changes I like to Firefox. It has been working fine until I tried to change the tab bar's overflow shadows when there are more tabs than there is space in the bar.

The rest of the css edits I've made in userChrome.css works fine but this overflow shadow reference Firefox just doesn't grab. I can live edit with the Toolbox and then it works fine, but when opening Firefox as default this css definition is as if gone.

Image 1: after live edit with Toolbox Image 2: before live edit with Toolbox Image 3: my userChrome.css

What can I do to fix this?

Thanks / p

It started today.

I can no longer sign into X if I have my Firefox browser setting "Never Remember History" enabled.

If I enable "Remember History" I can log in to X.

This has never been an issue before and is a bit frustrating.

I am receiving this error message when I try to log into my router. My router has a certificate from Let's Encrypt.

What settings do I have wrong?

Regards.

Hi,

I am encountering an issue where Firefox throws an "Uncaught out of memory" error in the console, despite my system having ample RAM available. Here are the details of the problem:

• Error Message in Console: Uncaught out of memory
• Memory Usage Observed: Using about:processes, I noticed that Firefox's maximum memory usage caps at around 7GB.
• System Specifications: The machine running Firefox has 128GB of RAM, so there should be plenty of memory available.
• Firefox Version: 126.0a1

Given the significant amount of RAM available on my machine, it seems unusual that Firefox would hit a memory limit at just 7GB. I suspect there might be a bug or a misconfiguration causing this issue.

Can you please assist in diagnosing and resolving this problem? Are there any settings or configurations I should adjust, or is this a known issue with the current version of Firefox?

Thank you for your help.

I am trying to add custom search engines to Firefox. I have tried the steps given in the forum thread https://support.mozilla.org/en-US/questions/1212596.

However when I try to go and add the search engine as per the article given above I do not get the option. Please see the attached screen shot for more details. I do not want to add an extension or a plugin, but just manually have the option of adding search engines.

I encountered a website today for which the reCAPTCHA dialog wouldn't appear. This is not a case of the endless blue circling of the reCAPTCHA screen. In this case, the reCAPTCHA screen does not appear at all.

I thought it was a problem with my account at the website since nothing happened when I clicked LOGIN. It wasn't until I tried Edge and the reCAPTCHA dialog appeared that I realized the problem was not with the website, but with Firefox not presenting the reCAPTCHA dialog.

I do not know whether the problem is with the site specifically since I have not encountered any other sites recently that required reCAPTCHA authentication.

Thanks... bms

Currently running Firefox v125.0.3 (Standard Browser Security) on Windows 11 Pro (v10.0.22621 Build 22621)

After upgrading to fedora 40, firefox just takes ages to boot up, even when it's running if I want to open a new window it still takes ages to run. I have tried uninstalling it and deleting it's data but with no luck. The issue still presists.
