Diễn đàn hỗ trợ Firefox

All my other browsers work fine but since April 4, 2025 Firefox won’t work at all. Websites won’t load. I have tried to clear my cache & cookies, I have checked my connection settings, I have checked for malware, I have turned off all my extensions and I have completely restarted my computer several times now, nothing has worked. I also did trouble shoot mode & reinstalled Firefox (though I will admit I maybe didn’t do this step properly). I refreshed Firefox. Why is it not working? What happened? I don’t know what to do as I don’t want to lose all my bookmarks and passwords that I have yet to move over to my password manager. Please help.

Helo team, I think I hit some key and firefox settings changed. I see squiggly characters in menu options, bookmarks etc.. Web pages load all right. I tried uninstalling/reinstalling. It did not help. Please see attached screenshots. I use a Mac M1 mini.

In recent weeks when I open my Macbook and go to https://meet.google.com, the page that loads says "404. That’s an error. The requested URL was not found on this server. That’s all we know." The issue is only on Firefox and not Chrome or Safari. When I see the error page, I look at the URL and it has the word "unsupported": https://meet.google.com/unsupported?meetingCode=landing&ref=https://meet.google.com/landing

So I dragged firefox to the trash, reinstalled and the issue persisted. I do not have a VPN. I'm using my own Wifi at home. If I switch to my desktop computer (m2 mac ultra) and go to the same Google Meet URL, I don't get a 404 error on firefox, however no one can hear my microphone any more as of 1 month ago, when I didn't have this issue in the past and I've done everything that everyone has told me to (in order to fix it) and nothing has worked.

Laptop: MacBook Pro 2021, MacOS Sequoia 15.0 Firefox: 13.0.1 (64 bit)

macOS. Firefox is running. I enter: open -a Firefox --args -private-window "https://apple.com" (in Terminal or Automator) which I believe should open apple.com in a new private window, but although the focus change to the already open Firefox window, a new private window does not open. It does work (apple.com opens in a new private window) if Firefox is not already running, but I thought the -private-window argument is supposed to open a new private window whether Firefox is already running or not. What have I got wrong?

I use a program called "URL Manager Pro" on the Mac to manage my bookmarks in all my browsers. Double clicking on a bookmark icon in URL Manager can open the URL in a new tab, the same tab, or a new window depending upon how I set the preferences in URL Manager Pro. This works fine in Safari. However, in Firefox, the website opens in a new tab regardless of how I set my preferences in URL Manager.

The author of URL Manager tells me the issue is a problem with how Firefox deals with AppleEvents. It's very annoying to accumulate so many unintended new tabs and then manually close them. Is this fixable in Firefox or is there a work around?

Thanks

we have 2 imacs here:

imac A just had OS catalina installed and firefox is shown as up to date running v 115.15. However, while it loads the apple tv website the site remains unresponsive to input.

imac B is runnning OS Sonoma and firefox is shown as up to date running v 130.01. There is no problem with the apple tv site, which responds to input.

So: why can't I update firefox to the latest version on imac A and why is the apple tv website unresponsive when it works on imac B running an older OS?

I am unable to use Fidelity Investments using Firefox Version 134.00. Just says "Service Unavailable" this site always worked with Firefox in the past. No problem when I use Safari.. Anyone else having this problem.

Hello,

I checked the troubleshoot and gave all the necesarry permissions on my Mac for Google Meet to use my screen (allowed audio, video and screen recording). Nevertheless, I cannot manage to share my screen on Google Meet. As shown in the screenshot, it offers the option to share my whole screen (I cannot select a window or a tab...) but for my audience neither this is working.

Could you please help me fix this?

Many thanks in advance!

hello all,

I'm running Firefox 115.18.0esr For a month now, tabs have crashed constantly. That is, *every single tab* crashes sooner or later and usually it's sooner. It's making Firefox unusable.

I know my desktop is old and my OS is considered obsolete, but still, I'm a fan of Firefox and want it to work. I'm running OS 10.13.6 (which I can no longer update) on a iMac mid-2011.

Any advice much appreciated.

My MacOS is 10.13.6 (cannot go higher on this machine). Since update to 15.119.0esr, embedded map graphics are no longer showing. The map graphic sub-window instead shows "Sorry, we have no imagery here" in several places across the map. I am getting the same for multiple websites, including the location maps in Zillow.com . Google Maps works fine, and I think the problem is isolated to maps embedded in pages. Did not have this issue last week, prior to updating to 15.119.0esr. This is SO BAD that if it's not fixable, I want to revert to 15.118...

Hi, I wonder if someone can help me log into the KeyBank website. I keep getting this message: "Due to technical concerns, your current version of Firefox is no longer an option for KeyBank online banking. Nothing is wrong with your account. You simply need an updated browser – like the most up-to-date version of Microsoft Edge, Google Chrome, or Mozilla Firefox – to sign on to online banking." My Mac indicates I have an up-to-date version of Firefox (78.10.0esr (64-bit) Thank you

When I try to access a movie or get further info by clicking the movie's pic, I get this message, despite deleting my cache and cookies, closing and opening Firefox, shutting and opening my MacBook. Any suggestions most appreciated!

That shouldn't have happened.

It looks like something went wrong on our side. Let's find you a great video to watch instead.

Hello support-type people,

I have a specific website that I have active in FireFox called myNoise.net. It allows me to generate background noise generators to cover-up the distracting noises from my neighbours when working at home on my desktop computer. The audio on the website worked the last time I opened Firefox ~2 July ... but today, when I opened the browser, the audio no longer works. I cannot get the website audio to load at all - I added the website to additional exception lists & shut down some content blocking extensions, but no joy. The website was already listed in multiple exception lists & I do not know or understand what change(s) occurred with the browser that would prevent this site from properly functioning - since it literally worked a week ago. I would appreciate any assistance and/or guidance with this issue, otherwise I will be eliminating Firefox as one of my browser options. I have provided a screenshot of the site that shows the perpetual "now loading" screen. Thank you.
