Diễn đàn hỗ trợ Firefox

Hi Yesterday I replaced my computer. I'm trying to sync my account data, but unfortunately, nothing is syncing. I have all the data selected for syncing (bookmarks, history, etc.), and the logs in about:sync-log are empty. It looks like the data from your server has been cleared. Firefox is freshly installed. Please help.

Simply put, I continue to get a message window telling me to update Firefox. I continue to get a response saying I need Windows 10 or later installed. I am running Windows 11 Home on my PC. Multiple attempts to get a reply on this from Mozilla Support. No replies.

Instead of syncing my current settings, sync just overwrote them with an old, outdated copy from another device, completely ruining my addons, bookmarks and various other settings. I managed to restore the bookmarks, but is there really no proper way to undo this or prevent such thing from happening in the first place? Is there no way to control if I want to sync my setting TO the server or FROM the server? How such a vital decision is even made then and why wouldn't there be a way for a user to control that? This is so disappointing :(

I need to recover a `.jsonlz4` file to restore a Firefox session with 8 active instances, as the "Restore Session" feature only opened 5 due to the `browser.sessionstore.max_windows_undo` setting being capped at 5, and the full original `.jsonlz4` file is now missing.

In the`firefox/Crash Reports` directory, there are numerous files I can’t interpret, can I retrieve my session data via telemetry or other methods using this crash information. I’m using Linux Mint with Flatpak Firefox, and I also have crash logs containing a "last crash" text file and a string of numbers, could these be useful for getting back my session?

Dear Anyone.

Trying to download Tampermonkey for Firefox. I'm NOT very good at computers, be nice! Every time I click on the "Add Tampermonkey to Firefox" button, I get "You are not online. Please check your internet connection." and it won't download it.

I AM on the Internet, tried it just now before coming here and it still won't believe I'm online. Everything else does. Why won't Tampermonkey?

Yours puzzledly,

Chris. Who's using Windows 10 on an antique computer that was designed for Windows XP! And Firefox, Best Browser.
