Firefox Community Forum

Hello! I am an avid user of firefox (especially with adblockers) on a windows 11 PC. Unfortunately, I have recently been experiencing an issue where when I attempt to open firefox, a window will open for a split second before instantly closing again. My PC is up to date, I have tried refreshing firefox and doing a clean install, but cannot seem to overcome the issue, or even open it in safe mode. Does anyone have any advice? Many thanks in advance!

Today randomly i noticed that my bookmark bar is waaay shorter out of the blue, i didn't change or adjust anything, all i do is the updates from mozilla that's all, it was all music it really saddens me because atm it's lost forever, i hope somebody can help me (i don't know since when it disappered i literally just noticed it right now ...)

For some reason text rendered in canvases (used by Minecraft hostings to display console) is distorted. I'm not getting this behavior in other browsers (including Zen – Firefox fork). The issue persists in both stable and nightly versions, with and without hardware acceleration, in safe mode too. Any clues?

Hello, I would like to know if the suggested in the URL bar have an expiration date, because sometimes they reset and the suggested that appeared first the day before no longer appear.

Since the last update Firefox sends the processor load through the roof. Both on desktop and on Android. For the first time since like version 7 I'm a bit disappointed.

What's up with this?

Why when I view a site in a private window are the cookies saved in the cookies and site data list on the privacy and security page of my main firefox pages. I though when you used private windows no cookies or history was saved once you closed the page.

The crashing is soo repeated- that even on an individual web page- it can crash over & over; a page won't remain open more than a moment (literally) & can crash again & again.

This's across different websites.

Just started like this week.

Any suggestions? Can Mozilla fix this??

Thanks!

Hi everyone,

We’re testing scroll-linked animations on a landing page built with Tailwind and custom JS for our client project hosted at https://noveltyads.com. Specifically, we’re exploring the ViewTimeline API and CSS animation-timeline for a horizontal scroll section.

While everything works smoothly in Chromium-based browsers, we’ve noticed Firefox behaves inconsistently in the following ways:

The animation-timeline: view() property doesn’t always trigger on scroll as expected.

Debugging with Firefox DevTools, the animations don’t appear in the Animation panel at all.

We confirmed that no polyfills or fallbacks are interfering.

This is happening on a custom-built section on this live test page: https://noveltyads.com (it’s a mock client version for internal QA — nothing behind a paywall or login).

Has anyone experienced similar behavior with Firefox’s scroll-driven animations or ViewTimeline implementation?

We’d love to know:

Whether Firefox fully supports ViewTimeline (or still considers it experimental)

Any DevTools flags or settings needed to see scroll animations properly

If there's a better way to ensure cross-browser consistency using native APIs

Thanks a lot for your help and insights!

I found that the sound produced when watching YouTube or any website that uses sound is very small, I tried to compare it with other browsers and Firefox sounds very small when compared to other browsers with the same volume and settings.

The contents of my Bookmarks Toolbar disappeared at the same time as a Windows 10 update. Instead of my bookmarks, I see "For quick access, place your bookmarks here on the bookmarks toolbar. Manage bookmarks." I right-clicked on the space and I have "Always Show" still checked.

To protect your security, eazypay.icicibank.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.
