Firefox Support Forum

I have used Firefox for years and had AVG free antivirus installed also for years. Tonight I had a popup window open from AVG informing me that AVG no longer support Firefox and have uninstalled their antivirus addon with immediate effect.

Does anyone know of a Free antivirus program that is any good and still supports Firefox?

TL;DR : Disqus comments used to work while using privacy Strict mode now it doesn't.

After years of it working out of the get-go while using Strict mode up till recently (about a year ago this was really low on my priority list) refused to work I though it was my Ad blocker was causing issues but after setting it in the filters to allow and even after turning it off still no dice.

Removed all add-ons tried again still Disqus comment section refused to load in the websites I regularly visit. So after giving up, I just look around in the browser setting to see if there is anything that may cause conflict with certain scripts from running.

I have set Firefox as my default browser. I can open it using a shortcut on my desktop. However, if I follow a link from an email, it does not open in Firefox. How come?

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.

All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

My Wife's computer - still on Windows 10 - says it can't start Firefox as it is still running, hitting the "close Firefox now" button just returns us to the same screen. I tried to uninstall and reinstall Firefox it tried to do a "reinstall" it says her profile is no longer available, while inconvenient she still should be able to start it up, but it still gives me the same message. that it is still running and needs closed. Trying to "close it doesn't do anything. I have restarted several times and even did a shut down and restart. Nothing seems to work. I assume some "stub" of Firefox is out there in the system/cache making Firefox think it is is still active but I can't find it to shut it down. Where do I need to go to "end task" on this phantom Firefox?

Other information: 1. We have Norton Security software installed, if that matters. 2. The same seems to happening to Thunderbird, but maybe I need to go to another help forum for that? 3. I am entering this issue from my computer that seems to be just fine with Firefox, so can't send browser data as it is irrelevant to the issue (it's on a different computer and install instance.

Hello dear community,

I have a program that continuously monitors the download folder under Windows 11 for a specific file and retrieves it. I download this file in Firefox, but the said program gives an error.

I have noticed that when files are downloaded in FireFox, they already appear in the Downloads folder with the corresponding file extension with 0 bytes and these are then apparently swapped or merged with the .parts file.

The problem is that the mentioned program now tries to retrieve the unfinished file, which then leads to an error.

Does anyone know if it is possible to customize Firefox so that the file only appears in the download folder when the download is fully complete?

Many thanks for your help :D

Several pages don't display properly. espn doesn't have a menu, cnbc displays and then goes blank, as do some articles on nytimes.com. These and other anomalies all work fine on safari. Any help greatly appreciated. Jim

I have been getting a message that says firefox has something running and cannot shut down. I went into task manager and 'shut down' firefox, but the message keeps on coming. I then thought that I would uninstall it and then reinstall, but it tells me that it cannot uninstall because it is running, -"Firefox is already running but is not responding. The old Firefox process must be closed to open a new window." When I click on ' Close Firefox' nothing happens. when I click on 'Cancel' the message disappears, but will reappear. Then in desperation, I went into program files and deleted the Fifefox folders but it wouldn't reinstall. There is obviously somewhere a file/file which is screwing me up, does anyone know what this it?

Hello, Firefox randomly downloaded a file, with seemingly randomly name, that is 0 bytes and in download manager the source is moz-safe-about. It happened when I was accessing a popular wiki site. I opened the file in notepad, it was empty. I put it on virus total and came back negative, as it is an empty file. I've curbed through the support tickets here, using the keyphrase 'moz-safe-about'. I understand this was/is quite a common problem, but it still makes me quite worried and left a sour taste in my mouth, as I haven't understood any of the explanations. I have enabled firefox to ask me whenever it wants to save something (I have no idea why this isnt the default state). Happened on a somewhat fresh, updated win 11 installation. I'm also attaching more information here with a picture. Long story short: should I be worried? Am I overreacting and this is just some sort of a bug that occurred while getting a sites data? Thank you for your time.

I've got a really old MacBook Pro that's still running 10.13, and Firefox has started displaying a nag screen telling me that this version is no longer supported, and to install a newer version of MacOS.

Is there something in the advanced settings that will stop it nagging me? I now know it's not going to get any more updates, there's no need to keep telling me every 20 minutes...

(Note to the devs: a "don't remind me again" checkbox would be nice for things like this!)

For System Administrative reasons, I want to disable automatic Firefox updates. Firefox can ask me if I want to install an update, but I get to choose whether or not to update.

This started a few weeks ago. I thought it might have been because I synced the passwords with other devices. I reverted it back.

When in about:logins, I click on the log in button but nothing happens.

Firefox decided to remove the total amount of homepage shortcuts. For months, it allowed for 4 rows and 8 columns, with blank "Add Shortcut" shortcuts. This allowed me to organize or split my shortcuts better. This morning, it decided to move all shortcuts together. As per the "Before" and "After" screenshots attached.

Usual disclaimers: Firefox 125.0.1 (64-bit) on Windows 10 No Config edits No extensions currently installed manipulate, affect or otherwise influence shortcuts

Please advise.

i am setting up a new laptop and trying to import all my current data from my old pc. Nothing is right. It imported alll the shortcuts on my toolbar from years ago. None of these are the current bookmarks from my old pc. ive tried syncing, importing again, nothing works. my bookmarks on my side bar are years old. I dont have ANY of these on my old pc as i deleted them years ago. what the heck is happening and how do i get my new pc browser to look exactly as my old pc looks. This is very frustrating. I have over 500 bookmarks on my sidebar. it looks like every bookmark i have EVER used. This is ridiculous.
