I used the CSS animation property called animation-timeline , which is written as:

element{ animation-time: view(); }

When I view the webpage on Chrome, Edge, Opera, and even on Phoenix browser, the animation works.

It is only on Firefox that the animation does not work. I even added the Vendor-prefix of " -moz-animation-timeline " to the CSS property, and it still didn't work on Firefox, while it is working on all other browsers.

The CAN I USE website ( https://caniuse.com/?search=animation-timeline ) tells me that Firefox does not support it at all.

It however said that I can enable it, by setting "layout.css.scroll-driven-animations.enabled" to true.

1.) I don't know what that means.

2.) Would my website's users be able to see the animation on their Firefox browser, if we assume that I make this setting ?

3.) I am using Firefox version 138.0.3 (64-bit) : What can I do to see that both I and users of my website are able to see this animation on Firefox ?

Regards.

I recently upgraded FF on this computer and can no longer sign in to my att.net email account, although I was able to sign in on another computer on FF earlier today. I just get an error message and Att can't help...is there a setting that has me locked out? I can also access email on other browsers just not the FF version on this computer.

In firefox, an extension no longer appears in the toolbar. It used to. Therefore I can no longer log in into that extension nor can I restore it to the toolbar. My version Firefox 138.03 64-bit. The extension is Phantom version 25.16.0

Lately, whenever I try to open a PDF from a website open in Firefox, the tab crashes and the PDF does not open. An error stating that the Windows file-dialog has crashed is displayed at the top of the tab. I tried to attach a screenshot of the error but that action only generates another error.

This condition does not occur when I try to open the same PDF from the same website open in either Chrome or Edge, the PDF opens properly which leads me to believe the problem is in Firefox and not my Adobe installation.

Thank you

After a Firefox update, my bookmarks menu, which was on the left side of the screen vanished. I have not been able to restore it. When I click the bookmark box (at the top of the page) I get three choices showing up on the upper left side of the screen. 1) Summarize , brainstorm, etc. 2) Tabs from other devices. and 3) History. So how do I get bookmarks???

Hi, In the last hour FF has stopped working completely. I made the mistake of using Ccleaner, which is probably the problem, I haven't had issues cleaning before, though I usually check the registry before deleting and don't recall seeing any entry for Mozilla (I may be wrong, though).

Firefox was working fine a couple of hours ago, but now it won't open at all, except in admin mode and then it won't open any links or tabs, not even settings. I've uninstalled FF, deleted the folder in the Programs folder, and reinstalled it from scratch, but there is no change (the one difference is that it wouldn't open in Admin after before I reinstalled it). Waterfox doesn't open either, but Thunderbird seems to work with no problems.

Thanks, Matt

Using 2025-04 Cumulative Update Preview for Windows 10 Version 22H2 for x64-based Systems (KB5055612) Firefox 138.0.1 (64-bit) and says it is up todate. I have looked at the about:config to find the browser.tabs.remote.autostart but it does not exist in the list of processes. I have also unchecked in settings both performance options intermitently to try and correct this problem, but nothing happens: (unchecked) Use recommended performance settings Learn more These settings are tailored to your computer’s hardware and operating system. (Unchecked) Use hardware acceleration when available Nothing pops up to allow choosing a different number as many support articles say. I have AdBlocker running as an add on and turned off the duck duck go privacy essentials and still nothing stops these insane amount of processes clogging up my computer. right now, on this page there is only this tab open and there are 13 processes running. Please send real fix instructions- thank you

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

Update: Still persists in 136.0.2

WHEN I SIGN INTO MY OUTLOOK ACCOUNT, FIREFOX IS BLOCKING MY CONNECTION. IT WILL NOT CONNECT TO SECURESERVER.NET. I CANNOT ACCESS MY E-MAILS IN FIREFOX CURRENTLY. PLEASE HELP! ALL THE TECH PEOPLE SAID IT IS THE BROWSER????

I AM HAVING THE PROBLEM ON THE OTHER COMPUTER. I THINK THIS PC IS O.K.

I accidentally uninstalled firefox and need to recover passwords and bookmarks. Can this be done? I run an old dell latitude with Windows 10 and was trying to cleanup apps running in background at startup since it was running very slowly. At one point I saw 2 firefox icons. Uninstalled one and lost everything. Can you help me. Michael Evans

I have McAfee+ Ultimate Family Security package and was attempting to set up its Password Manager. As it worked out their tech rep indicated that Firefox (which is my default by choice) does not support that particular extension for some reason. Is Firefox/McAfee collaborating to resolve this issue?

I saw this page but now I have lost it. The page has a blank space where the user can paste the url of a page to get a written record of the content of the spoken word in the page. The page is fairly small. I saw the page on Youtube. You can email me at pastorkelly_2002@msn.com

When encouraged b g mail to sign in to a site they want to let that site use our information and Mozilla seems to discourage that why? I have used Mozilla for years and have been very happy with!
