Diễn đàn hỗ trợ Firefox

Hello, I am transferring to a new device but my device is not syncing and just loading even when I tried to close and open Firefox. I've tried to also log this in via support but to no avail. Appreciate any help on this. Thank you!

I just installed Firefox on a new PC build and Twitch will load but just gets a spinning circle instead of playing the stream. The streams play fine on other browsers but i can't figure out why its lagging so bad/not working on Firefox. I did some digging and tried resetting cache and cookies and switched of recommended settings but nothing seems to work.

After having created a couple of tab groups with some of the numerous tabs that were already open in my browser (Firefox, of course) and then closing and reopening the browser shortly after, no tabs at all reopened even though this is my normal setting for Firefox: open all previous tabs when opening firefox. This setting had always worked before - as it does now with the new tabs. However, all my previous tabs as well as the freshly created groups have vanished. Do you have an explanation and ideally a way of recovering the tabs - or the groups at least? Thank you very much. Kind regards, Kerstin

I recently had to have my harddisk replaced as it had become corrupted. The technician did not reload Firefox or Thunderbird. I hope this can be done as a restore so that I find my bookmarked and favourite websites and my e-mails

Why is Firefox crashing so often? What changed? Is there something I need to do to prevent his? Once or twice a week or sometimes a day, but It seems to crash when I am just in my Gmail, sometimes 4 or 5 times an hour. Is Chrome a better option?
