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?

I have been using Firefox forever. It has been running very slow and bugging out especially with you tube on close. I've been working on this for a couple of weeks and am about to give up. My self built system is about 10 months old. Am using a completely debloated MS 11 pro 25h2. Did not ask for AI from Firefox and have disabled AI in Firefox and copilot is long gone. I have tried everything. Am about to quit firefox. Have refreshed firefox and prevented firefox from running in MS win 11 pro "efficiency mode". I usually have to exit firefox with task manager - there are usually 17 instances of firefox running. Mozilla has become Microsoft.

The system: Gigabyte B650 mobo, 32 gig of DDR5 6000, AMD 7700X processor and an Asrock 9060 graphics card with 16 gig DDR6 Vram. All other apps are running just fine. So I don't think a lack of compute is the problem.

Help please! Thanks in advance!

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.

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

Been using Firefox for over a decade. But lately is has become so slow now. Often freezes up if more than two tabs are open or a website is in any way very complex. What settings and issues should I check? What has changed? I can run the same sites on Brave and Edge browsers with no issues or not nearly as slow and bogged down.

Words duplicating, cursor jumping into the middle of words while typing in some fillable fields

I am using Firefox version 151.0.2 on android version 16, but I have been having this issue for months, since before 151.0.1. In some fillable fields on some sites, words duplicate as I type and/or the cursor jumps into the middle of a word. This is most frequently triggered by backspacing but can also happen when using numbers or symbols, such as when filling in a date with slashes or dashes. I've also witnessed it happen seemingly randomly.

Some situations in which this has occurred: -the tag field when creating or reblogging a post on the browser version of tumblr -the birth date field on my state's DMV website when trying to renew my car registration -multiple billing fields when trying to enter card information on a ticket vending site -this text box, the one I'm typing in right now to report this issue. Backspacing and using these dashes for this list both triggered the bug during the course of writing this up.

This has gone from merely irritating to actually being an obstacle (in the DMV example I could not get the field to accept any date format without duplicating and had to use the little popup calendar to select the day instead. What if that had not been a option?). My phone says both its software and Firefox are up to date. What else can I do?

Using the home screen search widget with the composable toolbar enabled(which can't be disabled anymore) on LG G8 causes the keyboard to open as usual but will not dismiss with the button or completing a search where it will attempt to dismiss but fail halfway through animation and block part of the screen.

Reproduce-able with these steps on LG G8: 1 Close Firefox 2 Open search widget from home screen 3 search something in url bar 4 Press Enter 5 Go to homepage, screen off, take a screenshot, or click on another text input box to make keyboard go down, sometimes with glitchy animation.

Not sure the exact cause but it also happens when browsing normally, i think its when a website loads and opens keyboard on its own.

Doesn't seem to happen on Samsung A16
