Hi Al,

Try updating to a new version of Firefox. Are you still encountering these high CPU issues? Thanks.

Comment 2

[Al Schapira]

Firefox is version 38.0.5-1.fc20, the latest that yumex knows about.
Yes, the problem persists.
It may be related to Adobe Flash Plugin 11.2.202.554, which frequenly also goes to 100% CPU.

Can't reproduce on Fedora 22, either with Nightly, nor with the latest release (FF43).

Could you perhaps try with the latest FF version.
38, which is ESR release, will get usually only security updates.

Other than yum/yumex I know of no way of installing the "latest" firefox under fedora 20.

Download from https://www.mozilla.org and tar xvfj <downloaded *.tar.bz2 file> in some directory
and run firefox there?

Downloaded Firefox 43, as above, and it seems to work properly.  However I get the following output:

[ads@ADS2 firefox]$ ./firefox
