This issue can be demonstrated when updating the Flash Player. If you are running the extension Ghostery, depending on your configuration, it can sometimes interfere with the loading of the Flash Player. There is one other add-on that sometimes interferes with Flash Player's function. So, if you have both Shockwave Flash and OpenH264, and you have problems playing videos on some pages, try going into the Add-Ons manager and setting the Shockwave Flash plugin to "Never Activate", then reload the problematic page. What happens is that the site, which is set up to detect whether you have Shockwave Flash or OpenH264 plugin, sees both plugins and tries to load both players, which results in an error, or a player loading but an inability to play the video. On most sites, Flash and OpenH264 will coexist but on sites like CNN, their video configuration fails if both plugins are active. For those sites, Shockwave Flash must be set to "Always Activate, or to "Ask to Activate". There are some sites, still, that use Flash as their player of choice, instead of OpenH264. This will allow videos that would not play or load to play normally.
The resolution to the problem is to set Shockwave Flash to "Never Activate". Until these two major developers can get their act together and work out the problem, there is a workaround. Therefore, it is a Firefox issue, and a Firefox 45.0.1 issue specifically.Īm I just stuck with this albatross, or is there somewhere I can download Firefox 45.0 and go back to that version of Firefox?Īfter playing with the settings, and reinstalling Firefox version 45.0, I found the problem.įor future reference, for those who are having the same problem, the problem is that there is a compatibility issue between two plugins: OpenH264 Video Codec by Cisco Systems Inc, v. I tried playing the same videos in Internet Explorer 11, and they load and play just fine. Before the update, everything was working fine. I began having the problem when I updated Firefox from v. I am running Windows 7 SP1 64-bit operating system, have plenty of RAM. On sites that have an indicator as to what percentage of the file is loaded, it will go up to 99%, but will never finish loading, if it is really loading at all.Īll my plugins related to video files are up to date. The video page and player will load, and the loading animation will start, but the video never loads. After the update, some video files will not load at all. In my case, all videos loaded fine UNTIL I installed the update that Firefox said it needed, which was to update Firefox 45.0 to 45.0.1. I read somewhere that the recent update from Firefox 45.0 to 45.0.1 was, in part, to fix an issue where some videos do not load in Firefox if third party cookies were blocked.
