Diễn đàn hỗ trợ Firefox

I recently switched from Linux to Windows and installed Firefox on my new system. I signed in with the same Firefox Account that I had used on Linux, but none of my bookmarks, shortcuts, or other data have synced. It feels like a fresh Firefox setup. Here’s what I’ve tried so far: 1. Confirmed that I signed in with the same Firefox Account. 2. Verified that Sync is enabled for bookmarks, history, and other items on Windows. 3. Triggered manual sync multiple times, but nothing has appeared. Is there any way to check if my bookmarks were stored on the Firefox servers, and if so, how can I retrieve them?

When I try to use Publisher's Clearing House games on an ACER Chromebook 315 the screen locks up at "please rotate your device" it is a laptop so of course I am not going to rotate it!!

I accepted an update to my computer and immediately Firefox could not load, the exe file is missing. Again I use windows 7 . May have lost all passwords and bookmarks. Please advise.

Using Firefox browser 126.0.1 via Steam Deck desktop running SteamOS 3.6.22; I am unable to download any extensions. I tried to download uBlock Origin and ProtonVPN through addons.mozilla.org, but recieved an error message:

"Installation aborted because the add-onn appears to be corrupt."

I then checked other extensions I found on the front page recommendations, like "Dark Reader" and "Image Search Options" and they gave me the same error.

Could not find anything that helped my situation upon searching for solutions, any help would be appreciated.
