My Blogger Videos Won't Play in FireFox
I am on a brand new MacBook Pro running FireFox 44.0 on OSX 10.11.3. I have upgraded to and installed Flash Player Version 20.0.0.286. Videos I have uploaded to my Blogpages (example: http://rhythmsofchange.blogspot.com/ ) show up at white squares and will not play (note: FYI they should be black screen and play audio only) . They play fine on Safari, Chrome and on my other laptop with an older version of Firefox. Can someone help please?

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History > Show All History" or "View > Sidebar > History") or via the about:permissions page.
Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks, cookies, passwords, cache, history, and exceptions, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.
You can't recover from this 'forget' unless you have a backup of the involved files.
If you revisit a 'forgotten' website then data from that website will be saved once again.
I get a white box on Windows 7 as well. Not sure what the issue is.
Is it necessary to serve the tracks as streaming Flash or do you have other options, such as MP3?
I don't know as well what is wrong there. In a profile where it doesn't work it works without problems if I switch the tab to Private Browsing mode or open the page in a PB mode window. In other profiles it works without problems in normal mode.
Edit: It suddenly started working when I cleared all caches (memory and disk cache). Ctrl+F5 doesn't seem to have any effect, but a full cache clear did.
Browser Console:
var cache = Cc["@mozilla.org/netwerk/cache-storage-service;1"] .getService(Ci.nsICacheStorageService); cache.clear();

Jscher2000 -thanks for suggestion, but blogger won't allow any audio files. cor-el - I cleared the Cache - no effect. I did replicate making it work by opening the page in Private Browsing mode. Very weird. I tried the "forget about this site" approach but it didn't help, though I am not sure I fully understood that and am going to dig into it again later. I also don't know what to do with
Browser Console:
var cache = Cc["@mozilla.org/netwerk/cache-storage-service;1"]
.getService(Ci.nsICacheStorageService);
cache.clear();
thanks to you both!

I notice in a regular tab that //www.youtube.com/get_player uses HTTPS while in a private tab it uses HTTP. Perhaps not coincidentally, the Flash plugin is not retrieving the crossdomain.xml file which may be necessary to embed the video. Comparison screen shots attached.
This difference could be related to "strict transport security", a header sites can use to force HTTPS instead of HTTP. I'm not sure of the best workaround.
the challenge here as I understand it is not unique to my computer, and it part of the current design of FireFox(?) Is that right? If so, how to bring this to Mozilla's attention to fix things? I'm not very tech savy, the help you are giving is very much appreciated!
I'm not really sure where the problem lies. Flash is a world unto itself and it's not obvious to me why the Flash plugin isn't proceeding to get the next file and play the video.
While anyone can file a bug report (https://bugzilla.mozilla.org/), problems that are internal to Flash generally do not get a high priority because Mozilla is trying to encourage developers to move away from Flash.
Does Blogger allow you to embed any other video formats? Formats like WebM (VP8) should play on all modern browsers, no Flash plugin needed.
i imagine blogger will allow other formats, but I am not eager to re-process the upwards of 100 videos I have on various pages... Thanks for the bug report link.
