1170568 - Animated personas do not work after restarting Firefox

Status: RESOLVED DUPLICATE of bug 819190

(Firefox :: Untriaged, defect)

Description

[u540525]

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:38.0) Gecko/20100101 Firefox/38.0
Build ID: 20150525141253

Steps to reproduce:

1) Install the animated persona from this link: https://addons.mozilla.org/firefox/addon/derpy-hooves-animated/
2) Restart Firefox
3) The background is no longer animated

This was tested on a new Firefox profile and the problem happens 100% of the time. Tested on two computers (Windows 8.1).


Actual results:

The background image is no longer animated. The only way to solve this is by disabling and re-enabling it, or by using the workaround by sean50350 listed on this page: https://support.mozilla.org/questions/965834


Expected results:

I expect the personas to remain animated after reopening Firefox. The workaround listed on the Mozilla support page works for a while, but every now and then the settings get reset and I have to apply them again.

Because these type of personas hase been disabled in Firefox due to bad performance for the user.

So what you're basically saying is that instead of adding something like a message to inform users that these kind of personas can have a negative performance impact, somebody ended up crippling a feature in a way that makes it work for once and not after re-opening a browser? Why are animated personas still a thing when it's disabled anyway?

I read through the bug reports that are related to this which I found through the link that you mentioned and checked my own system. I'm definitely not speaking for everyone when I say this, but in my case I don't care whether I waste a few hundred megabytes of RAM and some CPU cycles. The firefox.exe process uses 1% of my i7-3770k when its doing nothing and uses around 500MB of memory.

Instead of breaking a feature in order to improve performance it would have been preferable for those who have different priorities to be able to remain using said features. A simple warning about performance is more than enough...
