Firefox Support Forum

A few days ago I tried to download something from a modding website for a game, and the download simply failed instantly. I thought it might have been an issue with that website, but after pressing on with my plans with Edge and later trying to download Microsoft Visual Studio through Firefox, it failed again.

A week or two prior downloads were working fine, and I hadn't changed any Firefox settings between now and then. There's clearly something blocking downloads, but I don't know what. I'm not adept enough at fiddling with individual settings all day to know what they do or figure it out easily. All I know is that pretty much all of the conventional solutions from the most recent posts about this (2+ years ago) are not working. I've tried messing around in about:config and about:profiles, tried disabling and unchecking Firefox security settings, and changing the directory for downloaded files. I've even tried disabling Windows Firewall and Nord VPN.

This problem began a couple days ago. I have no problem accessing other sites on Firefox (and none for this site over years of use.) Can access site on Safari without problem.

Out of nowhere a couple days ago Firefox started loading local html files extremely slowly. I was using Live Server to render the pages, so I turned that on and off, uninstalled and reinstalled to no avail. I tried dragging files in from the original folder on my computer, but even that doesn't work. I tried updating firefox, and then my computer (which is running Fedora Linux 40), but still nothing.

When I try hitting inspect on the page, it only loads the HTML but doesn't let me inspect the JS as it wont load, and it's saying I have a ton of errors too. I can't look at the errors because they wont load, but I know it doesn't have to do with the original file as there was only one error which the page was working fine with before and each time I try opening the file it gives me a different amount of errors.

I tried clearing my cache and cookies, which didn't work either.

Does anyone know how to fix this? I'm having no other errors on other pages.

Hi Firefox team

I am Yuki belong to Electronic company IT department. We have a project to implement salesforce for customer facing and target to go live by end of this July. we are facing one issue related with firefox and salesforce.

<issue detail> Our salesforce have customized serach founctions. this search function doesn't work only in firefox browser(Edge, Chorme is ok). we can send input data from salesforce to search, however search result doesn't appear.

<current situation> we were investigating this issue with salesforce. we found this article : https://developer.salesforce.com/docs/platform/lwc/guide/security-lwsec-async.html >When LWS is enabled, JavaScript async functions that are used from a static resource work in Chromium-based browsers, but don't work in Firefox currently. The issue is a bug in Firefox.

<requet to firefox team> Would you solve above bug?

if yes, I would like to know the timeline
if no, I would like to know the reason why you don't solve.

Hi!

Every 10-15 days Firefox crashes on one of the machines.

The only error I have is the "No mapping between account names and security IDs was done" in the Event Viewer at the time of the crash.

Firefox and the system fully up to date. The system exhibits no other issues.

Windows 11 Pro, no domain, crashes happen on multiple accounts on that machine.

The user is not signed in at the time of the crash. They have been using the same add-ons for years, but just to rule it out, Troubleshooting mode was attempted to no avail.

AV has been completely removed temporarily to avoid any conflicts.

Hello, I cannot log in to Twitter/x.com with the Firefox browser. There is a constant loop when registering. Firefox browser does not connect Twitter/X.com.

Thanks for your Help.

Since my last upgrade my You Tube starts up in the tiny right hand screen, fails to go to full screen or just disappear unless I close Firefox and restart often multiple times. This only happens on Firefox and only since the last upgrade.

Recently firefox stopped playing audio, I have searched through the settings multiple times, tried safari and google chrome and they both still work so here I am for help.

So i'm a basic PC user and not a Pro to solve Problems related to Web browsers. İ wonder if this happens to any one out there using Latest version of Firefox. (127.0.2 64bit) PS:İ use a app called user agent switcher to fix freezing or lagging or buffering. İ have read some where on the internet that youtube is doing it on purpose?. This happens only with Firefox but not with Microsoft edge.

Hi, Archived thread on this from 2023 has no answers. Why is this browser so slow now and why is it glitching with resizing my windows? Beyond a total reinstall - how completely inconvenient - I would like an EASY FIX.

NOTE TO MOZILLA - WHY DON'T YOU HAVE A SOLUTION FOR THIS, NO REASON TO GO TO COMMUNITY 'IN CASE' SOMEONE HAS THE SAME PROBLEM!!!

I was sitting playing on the computer, I go to firefox browser and go to zelenka.guru, I look, and I'm not in an account on this site for some reason. I decided to go to another site, but there is the same problem, as I realized - for some reason I got out of all accounts on all sites.

Hello all. Having updated Firefox a few days ago, we can no longer sign into Instagram. This happens only on Firefox, only since the last update, and Firefox is the same browser we have been using for years with Instagram. The problem is the cookie permission window for Instagram a) will not make a selection and b) will not disappear/close. We have attached a screenshot. There are no close tabs/buttons anywhere on this window, and we have looked the full length of the expanded window. As we have not changed any other setting, have not added any software, and this only happens on Firefox, we can only conclude that we have missed something which may have changed or been upgraded with your last update. This is quite urgent, as this is to manage the Instagram account of a wildlife conservation charity. So far we have tried reinstalling Firefox, clearing cookies, and deactivating/uninstalling all add-ons, however this has solved nothing. Could anyone suggest a solution please? Thank you for your time and assistance.

For the past couple of days when I watch videos on YouTube on my iMac it's VERY slow to start. Sometimes it takes minutes, at which point I have to refresh, and best case it takes about 1 minute to start.

I have cleared the startup cache, cleared cookies and restarted Firefox.

Also, YouTube works normally on both Safari and Chrome.

Not a super 'tech' guy so any basic steps I can take are appreciated.

Thank you!
