Firefox Support Forum

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

Hello Good People,

I noticed that the snap version of Firefox had a lag issue when typing into input field. For example, when composing an email and wanting to use backspace to quickly delete a misspelled word, then backspace works slowly, stuttering and jittering. If I hold down a key in the input field it also lays the character down in a stuttery, slow way.

I tried reinstalling the system and that solved the issue. But it has returned again. Maybe it was an update. I also installed WINE and waybridge to get some windows plugins to work on my DAW. I don't know if that has affected it.

I also tried removing the snap version and installing firefox using the terminal but the problem persisted.

It's an annoying problem. Any advice appreciated.

I am unable to sign the petition because the whole form does not show up in Firefox.

Hi

I've been having an issue logging into Gmail using Firefox. I've used both Gmail and Firefox for years and have never had a problem, but I now get stuck in an endless loop on the Gmail login page. I select my account, enter my password, then get sent back to the account selection page.

The problem seems to be relating to me trying to link two Gmail addresses so that mail from one is forwarded to the other. I set up one account this way without any issue, but when I went to do it with a different account, I got an error code. After that, I was logged out of Gmail in Firefox and haven't been able to log back in.

Things I've tried so far:

• Using a different browser. I can log in without issues in Chrome.
• Logging in with a different method. Neither my password nor my passkey work.
• Logging in with a different Gmail account. All of my accounts seem to be stuck in this way.
• Disabling all my extensions. This doesn't help.
• Clearing Firefox's cache. No luck here.
• Restarting Firefox and restarting my PC. Turning it off and on again doesn't fix it.
• Contacting Google support. They said they think it's a browser issue as I don't have any problems using Chrome.
• Using Firefox's private browsing mode. This does work and I can log in to Gmail. However, I don't know exactly what the problem is because I've disabled all my extensions and cleared the cache in regular browsing mode and still can't log in that way.

So I have a partial solution (using Firefox's private browsing mode) but it's not a long-term fix. What else can I try? Has anyone else seen this problem before and been able to fix it?

I use a web application that lists items in a table, which provides a link to download the table as a CSV file. It used to work fine in previous versions of Firefox. However, in the current version, while the file save dialog defaults to a filename that ends in .csv and CSV is selected in the "Save as type:" drop-down, the data in the file that Firefox actually saves is in XML rather than CSV format. I don't know in which version of Firefox this behavior changed, as it's been a couple years since I tried to use this feature. Or I suppose it actually could be a new bug. I do know that when I use the same feature in Microsoft Edge, it saves the CSV file in the correct format, so this behavior seems to be peculiar to Firefox, rather than anything wrong with the web application.

hello, I've been trying to follow Firefox's official guide in the docs and ready 3rd party articles in order to enable payment method auto-fill in Firefox. however, this section seems to be missing from my settings page.

under Privacy and Security, I cannot find anything to do with saved payment methods or the checkbox to enable payment method auto-fill.

how can I resolve it?

I cannot remove "Your browser is being managed by your organisation" and seems to be stopping the home settings saving. They simply revert back to the default (see image) when I restart Firefox. Not sure what is meant by "your organisation" as I am a personal user, not organisation. I'm the single user of the browser (e.g. just one user on my PC, which is me) and also Admisitrator. Can someone help me remove this. Thanks John

I am using KDE plasma 6.0.3 but the problem was also present when i was using Hyprland as my desktop enviroment. I tried troubleshoot mode but nothing changed. I am seeking help. Thanks.

Just recently Firefox seems to have its downloads capped at 15-16 meg speedtests show the full 1Gig speed OPERA AND EDGE both download at the full 999 megs but firefox has recently stopped downloading any faster then 19 meg

what in firefox could be causing this its not happening in any other browser.

Just updated a friend's computer from Windows 7 to 10. Installed firefox over previous ESR and now there's no way to remove the search bar from the new tab page. On my W10 system, the search bar isn't there, not sure how or why, but on her's there's no option NOT to show it as there used to be.

I found some VERY old (2014) info on this but doesn't seem to be up to date.

PLEASE give us our options back and stop taking them away, sheesh, getting as bad as Microsoft.

Is there a workaround for this to remove the redundant search bar from the new tab page since you can search from the address bar?

Thanks!

how can i get past this? All help appreciated!

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

I have Windows 11 and the Firefox 124.0.2 browser. I cannot update to the latest version of Firefox. I receive an error message "Failed to update". I've uninstalled and reinstalled the browser, ran the install utility selecting update, nothing seems to work. Please help

Duplicate question, please continue in your 2nd thread: /questions/1445013

Nothing happens when I press the play, like, dislike, notifications, favorite, or join server buttons. On top of this, when I try to open the catalogue it's just a grey screen with nothing in it. In the attached GIF I am clicking rapidly. I don't believe this is an issue with roblox itself, as when I open chrome everything works perfectly. The only extensions I am using for the site are RoPro and BTRoblox. I have tried to turn the extensions off and have even uninstalled them, however the problem was still not fixed.

Prior to update 125.0.1 corporate intranet users could download PDF files from our Line of Business applications / Webpages. Today after the latest update the PDF files download but are corrupted. The site was added to the trusted webpage without improvement.

Adobe Acrobat Reader could not open ********.pdf because it is either not a supported file or because the file has been damaged

Hello, When i create a new tab (cntrl + T) I can no longer just start typing and have that be a google search. Now I need to manually click in the search bar. Is there a way to enable it so creating a new tab automatically puts the text into the search bar field?

Not sure why this stopped working, maybe a recent update. Thanks for your help.
