Diễn đàn hỗ trợ Firefox

I had this issue a few months ago but it then seemed to resolve itself. Now it's back.

I use passkey on a few sites like Google, Youtube, Hubspot... every time I attempt to use passkey on such sites Firefox locks up and I can't select anything on the page, a different tab. It just completely locks up and I have to restart it.

I always deselect cookies.

I don't have this issue on Safari so it is the only way I have to deal with this issue.

When watching videos, switching between my Bluetooth headphones and Mac speakers will cause the sound not being able to output correctly, the video will be seem muted. Sound output is fine when using other explorer and apps. Restarting Firefox will usually fix the problem.

My search history has disappeared. View/history shows a blank page. If I select "history" from the menu, "recently closed tabs" and "recently closed windows" are grayed out, and "recent history" is empty. But I've been to a dozen or more sites today. What can I do to make Firefox record my history?

When shutting down the computer through the OS, Firefox closes each window separately instead of quitting (e.g. with Ctrl+Q). Windows with multiple tabs ask for confirmation, stopping or delaying the shutdown process, and single tab windows close and are not restored. I have to manually quit Firefox before shutting down the computer every time if I want my session to be correctly restored.

I have been using Firefox for a long time, and remember it working nicely with shutdown/logout. This issue showed up after changing my OS, so I believe it must be related to Flatpak, Fedora, KDE, or a mix of them.

suddenly after a firefox upgrade this afternoon, the contacts lists for gmail started to get reduced in size so small it looked like specks of dust instead of names , adresses, etc.

another pc here which hasn't been upgraded  has no problem.   both pcs have the same 5 GMAIL acccounts, 

but the secondary (also sedentary ) has not been used for 2 or 3 days. Both are laptops, with Win 11 and are upgraded as soon as they available

I have attempted to sign in to MyHealtheVet.gov 3 or 4 times over as many hours. Every instance has encountered the same message "Secure Connection Failed. This is the Verterans Administration website and find it hard to believe their website is not secure. I'm not a computer geek, far from it, hence utilizing this method of contact. I have been notified by email that I have a secure messaging message on the VA site that I am unable to access/ Thanks in advance,

Every single time I close my Firefox and open the browser again, it reverts back to a previous theme that I already deleted. When I open the Add-ons manager, it shows that the theme I want is enabled but the wrong theme is the one active. I have to click the "disable/enable" button to toggle it on and off to re-enable the theme I want. I've looked this issue up but haven't found any answers. I appreciate any help!

When I click on a link on Firefox / Mozilla I get a "Hmm. We’re having trouble finding that site. We can’t connect to the server at ad.doubleclick.net" message. If I do the same on Brave, that doesn't happen, it will show the link that was clicked on. What can or may be the problem? This happens way too often, for example on "Newsmax" links.

I enter msn.ca on an open tab, https://www.msn.com/en-ca is displayed in the tab window but no content is displayed. No extensions are enabled.

Works in Edge browser. Also doesn't work with Brave browser

Hi all,

I would like to know if this color issue is expected behavior or a bug somewhere on my system.

I am using a monitor (Acer ET322QK wmiipx) which displays color at a depth of 10 bits per channel (for a total of 30-bit color depth). When viewing images which have color depth exceeding 8 bits per channel, color banding is visible in Firefox that does not appear in GNOME Image Viewer, indicating that the image is not being displayed at the correct color depth. I've attached an image with 16 bits per channel color depth as an example. This sphere render is deliberately dim to make color banding more obvious. It should look smooth/unbanded on a display with support for colors with greater than 8 bits per channel.

By opening the Firefox console with Ctrl+Shift+K and entering "screen.colorDepth", I have confirmed that the display is identified by Firefox as having 24-bit color depth.

With the upgrades to Firefox, I now cannot load any websites, even Mozilla Support pages. Have to use a different browser. Might this have to to with DNS over HTTPS? HELP! Thank you, very much.

Hello,

As my title says, there's no Closed Captioning available on ABC.com. It was working last night but tonight it's gone. It's only an issue on FF for Desktop. There's no problem on FF for Android and also no problem on Chrome for Desktop. There's no problem on any other video website like YouTube, Peacock, etc. It's just ABC.com. I tried restarting FF, reloading the website, clearing the cache, etc.

There have been quite a few FF (Desktop) updates over the past few days. There was even one first thing this morning before I tried watching something on ABC.com. I wonder if an update is causing this glitch.

Any ideas??

Thanks, Andre'a

Dear Mozilla Support Community,

This is a rather interesting observation I've recently made, but it appears that with every new software update on my Firefox Developer Edition browser, that I inexplicably (and mysteriously) get signed off/logged off of all my already logged in websites, and while this isn't a major tech issue, per se... It is an annoying one and I would like some clarity on this.

Is there a feature that toggles this on and/or off? Or perhaps, this is a known bug? What is the bottom line on this?

Thank you!
