Firefox Community Forum

Hi,

I am using macbook pro latest one, and when I use firefox and scroll down from my wireless Mouse to the bottom of the page, the scroll bar jumps to the top while working, is there a fix for this.

Thanks

Is anyone looking into this? I found an article that told me to remove some cash files and it seemed to fix the issue but it continues to reoccur. Some apps such as MS360 Outlook seem to trigger it, but if it was truly just a corrupt cache issue then cleaning the cash/profile once should have fixed the issue. Instead its become a constant pain in the *** and I'm tempted to find another browser. Seems very recent as well as I've never had issues with firefox before.

Ubuntu 24 Mozilla Firefox 151.0.3

Estoy observando un comportamiento específico en Firefox que no logro reproducir en otros navegadores basados en Chromium.

Escenario de prueba:

Sitio web con un visor panorámico personalizado. Imágenes panorámicas de aproximadamente 4.500 px de ancho. Movimiento horizontal continuo y lento. Sin reproducción de video ni elementos pesados adicionales.

Resultados observados:

En Chrome, Edge, Brave y Opera el desplazamiento es fluido desde el primer instante. En Firefox el desplazamiento comienza con pequeños tirones o saltos visibles. Los tirones disminuyen progresivamente y desaparecen después de aproximadamente 4 a 12 segundos, dependiendo de la cantidad de panorámicas activas. Una vez estabilizado, el movimiento es completamente fluido. El comportamiento se reproduce incluso utilizando una sola imagen panorámica. Si existen varias panorámicas, el síntoma vuelve a aparecer cada vez que una nueva imagen entra en pantalla.

Pruebas realizadas:

Se descartó que el problema estuviera relacionado con transiciones entre imágenes. Se descartó que estuviera relacionado con programación o temporizadores. Se probó con una sola imagen activa. Se probó utilizando distintos métodos de desplazamiento. El comportamiento sigue siendo exclusivo de Firefox.

La impresión es que Firefox requiere algunos segundos para estabilizar el renderizado o la decodificación de imágenes panorámicas anchas antes de alcanzar una animación completamente fluida.

¿Existe alguna recomendación específica para animaciones panorámicas continuas de gran ancho en Firefox?

Firefox MAC freezes intermittently , will get spinning beach ball and status shows Firefox (Not Responding) and must force quit FF.

Sometimes FF after fresh down load from the official FF site for MAC will work great for an hour or half a day and then out of now where go into the spinning beach ball , and unable to enter data into any field - completly bricked and FF status shown as Not Responding. Tnis could happen immediately, or after an hour or anytime within a day or two.

No way of deciphering or determining what in the heck triggers it or why - way way too many factors and settings and variables both within the FF registry and the macOS and the activity I may or may not be doing at any given time.

I will say I experienced this when all apps on my MAC were shutdown, no apps up and running, but I do use Backblaze, Mai Backup X, Malwarebytes, Dropbox, MS NTFS Tuxera, DriveDX which all have ongoing background tasks running all the time or at least in the background from time to time.

However, I have used this setup for the last few years with Firefox MAC with absolutely no hiccup whatsoever.

And then immediately after the last FirForx update on Tahoe, just before I applied the latest 16.5.1 Tahoe upgrade is the intermittant freezing with FF started.

Could this be a FF / Tahoe incompatibility issue?

If not, does anyone out there have anything to fix this?

And yes i did a complete uninstall of all of FF hidden Library folders as well as the "firefox.app" itself - if anyone tells me to uninstall all the hidden FF folders and files in ~/Library one more time, then forget it, I am done using FireFox. Been there and done there a number of times the last week, exhausted with that, and doesn't do a thing.

And yes kept deleting and creating new FF profiles and did not fix the issue.

So does some great genius Mozzilla FF Mac SW engineer have any clue as to the real issue and the real fix without sending me on a wild goose chase?

thank you. clb6
