Diễn đàn hỗ trợ Firefox

In firefox developer edition, when opening a new window of any kind, or when relaunching/opening the app, the new tab button always ends up on the left hand side. Going to the customization menu, I can move the button to the right side (next to the last tab), which is where I prefer it, however when opening any new window the button goes back to the left side

I'm getting "Too Many Requests" error message this morning when I try to login to MS Outlook. My OS is Windows and I run Proton VPN.

NOTE: I do not GET this error when I use the DuckDuckGo browser to login to Outlook.

All shortcuts I had for months below the search bar are gone from the home page of ff. Nothing suggested in the past I try ever fixed it. They just showed back up one day long ago. Until today I refreshed FF did not work. When I tried to browse it will not let me access the desktop to attach a photo this is only when using FF.Thankyou
