[Timothy Nikkel (:tnikkel)]

I wonder if bug 619176 helps with this.

Comment 2

[Timothy Nikkel (:tnikkel)]

I thought this bug mentioned scrolling, but is doesn't look like it, so the previous comment is probably not correct.

Comment 3

[Benjamin Smedberg]

Which process has the high CPU usage? firefox.exe or plugin-container.exe? This is probably a dup of bug 612113.

Comment 4

[Alice0775 White]

plugin-container.exe is.
bug 612113 did not mention any regression range. so I do not know this is a dupe or not.

Comment 5

Unless this also causes noticeable lag or stuttering, I really don't think this needs to block. A profile might be nice, but since it will include Flash that might be a bit tricky.

Life of the battery of the laptop PC will become the problem
