I have upgraded from openSUSE-13.2 to Tumbleweed (x86_64), successfully. The OS is working fine in my Dell Laptop with Intel® Core™ i5-4210U CPU @ 1.70GHz ×4 & Haswell-ULT Integrated Graphics Controller. But my Firefox Browser does not play any videos of any denomination. Even YouTube videos are not played. I have ‘flashplayer’ and ‘Videos (Totem)’ applications installed.
Will greatly appreciate help ;).
My remark was about “switching to Packman”. Subscribing to the repo is only part of that action. You must also do the “switch” by either using the repo view of YaST Software management then click uper right tth “switch …” text, or
I asked if you switched to the packages offered by Packman (that is, those packages that are in both OSS and Packman).
You answer was that you added the Packman repo to your repo lits. As adding a repo does not change anything in itself, but only makes it possible to use that repo, I asked for confirmation that you realy did something with that repo. Specialy if you did one of the actions that replaces the packages that are both in OSS and in Packman to the Packman ones. In other words: did you switch to Packman.
And in case you did not switch, I also explained the details on how to do it using YaST or zypper in my post above.
When you have the correct Packman (Tumbleweed) repo in your repo list (and of course np other Packan repos from other openSUSE versions), just start YaST > Software > Software Managemnt, then use the View button and choose the Repositories View from there. Then select Packman at left and then click above the list at right in the text "Switch system packages to the versions in this repository (Packman repository)
I do not know at the moment how to explain it better. But please start using these instructions. Then when you got stuck somewhere, you can come back with the details and ask further. IMHO it is better you start doing something and see for yourself so you can ask about what you see.
I have now upgraded to Firefox-44.0, but videos still do not play properly. But some progress has been made…
When the video-play window opens in Firefox, there appears a thin line on top of the window with a cross at the rightmost end of the line. If I click on that cross, the line disappears and then the video starts playing clearly.
