Diễn đàn hỗ trợ Firefox

I'm using Firefox 124.0.2 (64 bit) on Windows, and every few days I get the error about using an older version of Firefox, with Exit or Create New Profile options. I then run "firefox -allow-downgrade" from the command prompt and everything works fine... for a few days, when it happens all over again. This only started happening a couple of weeks ago, but it's getting really annoying. How do I stop it (short of using something like Waterfox or Brave).

So I have an Excel workbook in my onedrive from MS, It was working fine on my firefox browser in my Ubuntu OS, last week it started to delete my cell's information whenever I pressed the enter, tab or arrow keys, I contacted the MS support and they get me to opened the same file on a chrome browser and worked fine... I still want to use my firefox browser but this problem is very annoying, please help me sort it out!!!

First, I am disabled

When I goto to YT Homepage it will play all the sounds of the downloaded video's when I hover with the mouse.

But I want to hear the sound of that video AFTER I selected that Video or clicked on the title.

Thx!

I am unable to sync my Meta Quest 2 FireFox bookmarks and data with my PC Firefox browser I press "sync" on VR but nothing happens. I am signed in under the same account for both devices
