Φόρουμ υποστήριξης - Firefox

I have account, where i have passwords/logins, bookmarks, etc. Some days ago i as usual reinstalled my Windows, installed Firefox, and tried to Sync. Sync was done, i pressed Sync on Account button, and nothing happens. Then i tried to see my pass/logins there: about:logins , but there is empty. And my bookmarks doesn't show.

How can a get back my logins, passwords, bookmarks, plugins?

hey guys,

there doesn't seem to be an option for this. is there? if there is, I can't find it. see attached image for what I'm doing now. as it stands now, I have to manually push the DELETE button one time for every entry that is in that window for saved passwords. there has to be a better way to do this to get rid of all of them! can you guys help me with this?

I'd like to add Firefox to Adobe Dreamweaver for site design viewing. When searching Windows for Firefox.exe I don't see it in Program Files or Program Files (x86). Firefox is installed and used daily. Can someone tell me where it's located in Windows 10?

How can I do keyboard shortcut, "Text encoding options", then "Unicode". I have it on toolbars. Like on screnshot, I pint mouse, then I need to select Unicode, which is bothering. I am opening many many pages, which are always different than unicode.

I recently upgraded my Windows 7 laptop to Windows 10. Now in Facebook, videos won't play. I am using the latest Firefox and Flash player. The picture for the video shows up, but when I press play, it turns to a blur and won't play. I restarted Firefox in safe mode and the videos play normally, so it is an add-on causing the issue. I have disable each add-on, but can't seem to find the culprit. Maybe iI am not fully disabling them?

This raises another question...do I still need Flash Player at all? Do browsers now have other ways to play the videos?

Thanks in advance
