You started pushing a widget a while back that shows the days I've been on Yahoo, concurrent and otherwise. This thing is annoying and I want it gone. I don't care how much I've used Yahoo on my devices and You already know via tracking cookies.

Make it go away or tell me how to get rid of it - PLEASE.

I cannot find Firefox About - Help because I don’t see the toolbar that is supposed to contain the About button.

I am using Firefox 147.2.1 (67326) on an iPhone 13 Pro 26.2.1

Any help is much appreciated!

In my org - ever since the release of Firefox 146 - each time an update is rolled out on a WIndows 11 endpoint - Firefox is no longer able to launch.

This is resolved by uninstalling and reinstalling the client. We've had no issues with the ESR release in my testing.

What changed? Anyone else experiencing this?

I had our security team take a look at the antivirus - they've confirmed we aren't blocking Firefox and they did not see any block reports.

No relevant policy changes have gone through around the time of the incident. Initially I suspected users were installing Firefox ESR from the Company Portal alongside the standard release - but confirmed this is not the case. Also ruled out browser extensions - error persisted across a config without any extensions.

Please let me know if there is troubleshooting info I can collect. I included info from my own browser, but I reinstalled on the 27th and it has been working since. However, it has broke specifically on the days new releases have come out.

Thank you for any suggestions!

I won't show my account information but when I try to access Amtrak's Guest Rewards site it goes into a loop. First it asks for username & password and accepts that with no problem. Then it asks for the code it sends to my cell phone and accepts that. And then it just keeps reloading various pages until I kill it. This is the error message shown in the log, it's repeated over and over:

NS_ERROR_ILLEGAL_VALUE: Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIFaviconService.replaceFaviconDataFromDataURL]

I'm running under Mac OS 10.13.6 The site loads fine when I use Safari (version 13.1.2)

Thanks

I’m seeing a layout and font spacing issue in Firefox that doesn’t appear in Chrome or Edge. The page loads, but some elements shift after render and text spacing looks off.

I’ve tested in a private window, disabled extensions, and cleared cache, so it doesn’t seem profile-related. Any suggestions on what Firefox settings or DevTools checks might help?

Page where the issue is reproducible: dbrosmenu.com Thanks.

thank you for your time & expertise:) Can you please help me understand what would happen if firefox stops supporting windows 7 users. Will i still be able to use the browser - just with less security? I will probably have to give up using a computer if I cant continue with Windows 7 so I'd even be prepared to pay an annual fee to keep the support going. Look forward to hearing from you, thanks Julie

They play for a couple of seconds, then the panel they are playing in goes black. They used to work a month or two ago. Videos play fine in YouTube. They also play fine in apps like VideoPlayer and VLC. They play fine in Chromium based browsers Opera, Brave and Vivaldi. My graphics card requires switching acceleration off. I can’t find a switch for that in Firefox.

Problem Videos start playing, then after a few seconds the video panel turns black. Audio may continue. Refreshing does not help.

Environment

   OS: Fedora Linux 43
   Firefox 147.0.1 (also tested Firefox Flatpak)
   Display server: Wayland and X11 (both tested)
   Hardware acceleration: on and off (tested)
   Media Source Extensions: enabled (disabling MSE triggers an “unsupported device” error)

What works

   BBC News videos play correctly in Chromium-based browsers (Brave, Vivaldi)
   Videos play correctly in mpv/VLC
   Other video sites (e.g., YouTube) play correctly in Firefox

What I’ve tried in Firefox

   Disabling hardware acceleration
   Disabling VA-API
   Disabling WebRender
   Disabling RDD sandbox
   Running Firefox under X11
   Using the Firefox Flatpak build

None of these measures help. This suggests the issue is related to Firefox’s interaction with BBC’s player on Linux. Has anyone else seen this, or is there a known workaround?

I am unable to sign in to my yahoo mail account. It gives me a fault that "something went wrong, please try another device". I can use brave as my browser and sign in with no problem but not with firefox. Any idea why?

I recently purchased a new HP laptop to replace my old laptop. On the old laptop I used Firefox as my default browser. I do not care for Chrome or Microsoft Edge. On my old computer I had installed Trend Micro Toolbar on my Firefox browser and loved the protection it gave me on the web. However, since I purchased my new HP laptop I have been unsuccessful adding Trend Micro Toolbar, so I have had to settle for using Chrome. Can you please advise me how to add Trend Micro Toolbar to my Firefox browser?

Hello,

When I try to visit a specific journal site that requires authentication, the browser automatically redirects me to an authentication page that I have used before. This is very annoying because every time I click a link to the journal, I’m sent to the other portal and can’t access the article. I want to stress that I haven’t installed any add‑on that would cause this redirection. I think I did that myself manually but I have no idea how. I’ve already deleted the cookies for both sites, but nothing has changed. I hope that makes sense, it’s a bit difficult to explain.

I'm using firefox 147.0, on mac Tahoe 26.2.

Thanks for the help !

I've been using Firefox on Linux since it was Nautilus. Currently running EasyOS Linux Daedalus and Excalibur on different Lenovo ThinkCentre Tiny Core i3-8100t boxes and different drives: A good Samsung SSD and two good flashdrives. 32G new RAM installed on each box. I've been using these boxes for over a year. For the last month or so, ever since updating to v. 146 my tabs have been crashing like crazy! I don't normally have more than 10 tabs open at once. But now, as soon as I open a 5th tab it crashes.

I'm running Top to watch CPU and RAM usage. I see nothing unusual. I've rebooted. Disabled all add-ons and run in Troubleshoot mode. Tabs still crash. My only add-ons are uBlock Origin, Temporary Containers and Dark Mode. It happens whether I have hardware acceleration turned on or off. I don't know what else to try. Here are my most recent crash reports. I hope you can figure out the problem. Thank you so much!

Hi, I've recently discovered that Firefox replaces the % with underscore while downloading file.

I've read that question: https://support.mozilla.org/fr/questions/1439267 but there is no answer.

Is there a way to prevent that? I use a online tool I've made myself and the % is used as a separator.

I have been using Firefox with Dragon Naturally Speaking Professional 16.1 since 2022. Never had a problem with dictating into any boxes or search bars before today. Now I cannot dictate into those and I need to. I am a quadriplegic and ventilator dependent and need to use Firefox and be able to dictate into it. Can someone tell me what to do to get that to work again?
