Please help an old dummie? I have an existing FF install on a laptop. I would like to clone it (with bookmarks, settings tiles etc) onto a new PC. An article I read said open FF on the PC you want to sync. This is confusing! "Synchronising" is ambiguous, meaning 2-way. (but which way) "copy from" & "copy to" would be clear. I am worried I will synch(copy) from the new to the old....... effectively deleting/wiping out all my preferences in my original install. OR (preferably) Is there a way to just copy the whole installation from my original PC onto a USB stick & installing FF to the new PC from it? Many Thanks

I'm using openSUSE Tumbleweed and KDE Plasma. Ever since I updated to Plasma 6.1, Firefox crashes constantly when using Wayland. I'm not having this problem if I'm using X11. Crash reports are sent after every crash so I'm sure someone can reference these. When starting Firefox from a console, I got this message after a crash: "[GFX1-]: Wayland protocol error: wp_linux_drm_syncobj_surface_v1#67: error 5: explicit sync is used, but no release point is set"

Will this get fixed with the next Firefox update? Currently using 127.0.

Firefox keeps going off for from 5 seconds to about 20 seconds. It happens several times a minute. The screen goes blank and I can’t click on anything. Really aggravating. I would appreciate any help. Thanks

HELP! I am currently using Thunderbird ver 115.13.0 and Mac OS 14.5 Sonoma and a 2018 Apple MacBook Pro 15 inch laptop. I have recently noticed that incoming emails with colored text responses included in the email response is not visible, i.e. the text response is completely missing. In addition when trying to reply to an email with a colored text response - the text is not showing up in any color except black. This is extremely frustrating. I have been using Thunderbird for over 15 years and am seriously considering moving to another email client. Any ideas?
