Youtube does not work. It shows somekind of default page that is essentially blank. It does say: "Try searching to get started" and "Start watching videos to help us build a feed of videos you'll love."

But it will not respond when I attempt to search anything.

Hi, I’m facing an issue where some websites do not load properly even after clearing the cache and cookies. Sometimes images don’t show or pages freeze. Is there a method to force fresh loading or bypass the cache?

Thank you.

I can log into a random website and it goes right in then turns black and i can't see anything, i shut it down .... bring it back up and it does it again, any ideal what is happening ?

Log onto Firefox. Go to Yahoo mail, log off this and yahoo homepage shows daily pop up which is some sort of counter ("Don't ghost us" day 1,2,3, on on Google says this is a browser issue, Redirect to Chrome same thing. Have adblock on. All settings on all 3 browers do not stop it

When browsing with Firefox, scrolling with the up/down arrow keys intermittently causes the keyboard to be disabled. Trackpad and touchscreen still function, but keyboard becomes completely disabled, requiring a reboot.

I've had this problem for over a year and through several versions. It also happens when running in safe mode, so that should eliminate any plugins.

This ONLY happens while browsing with Firefox browser. I cannot deliberately reproduce this, but it happens frequently - up to several times a day. It seems to be tied to scrolling with the down and up keys. This only happens in Firefox, not in any other apps or browsers.

Can anyone help me isolate the problem and find a fix? I am a retired programmer, so I should be able to get to the bottom of this with some help. I suspect that my env may be so unique that nobody can

I recently noticed a scenario where a web tool loads updated data (via JavaScript and backend API), but the browser (and proxy cache) still serves outdated content when viewed on a different device. Clearing the browser cache fixes it, but that’s not a scalable solution for users.

I’m curious: does Firefox’s caching behavior differ for pages that use heavy client-side updates (e.g., incremental score calculators) compared to standard static pages? Should we be explicitly sending cache-control headers like no-store or must-revalidate to prevent stale data?

Any documented guidance on how Firefox handles cache revalidation for dynamic web-apps would be helpful.

Thanks in advance for any pointers.

Hello Mozilla Support Team,

I am writing to report a problem with the Mozilla Firefox browser. After the latest update, the browser appears to no longer decompress content that is compressed using the zstd (Zstandard) algorithm.

Previously, I could view web pages or resources compressed with zstd without issue, but now they fail to display correctly (or give errors). I have tested this on multiple websites and different systems, which suggests the change is not specific to one site or machine.

Could you please clarify the following:

Has support for zstd‐compressed content been removed or disabled in the recent Firefox version?

If so, are there plans to restore this support in a future release?

Is there a workaround or configuration setting that allows enabling zstd decompression in the meantime?

Thank you for your attention to this matter. I appreciate your help in ensuring this functionality is restored or clarified.

Best regards, Oleh Boiko Windiws 10, FF 144.0.2
