High cpu usage by firefox After power failure
Hi guys,
I am using slackware 14.2 32bit on my dell vostro 1015(core 2 due 2.10 ghz, 4gb ram, intel graphics).
Some days ago my system shutdown because of a power failure while firefox and chrome were running.
After the reboot both the browsers start using a lot of cpu .
I tried deleting .mozilla folder from my home dir and .cache dir ,deleting some unused plugins, and a complete reinstall of firefox but the problem is still there.

Maybe run a live gparted session on a live iso and
do a check on your slackware partitions also.

I don't run firebug but if you do, the line from your core-dump looks odd ( I broke the line on the '<' symbol ):
Maybe turn off or uninstall firebug if it is installed ?
Another suggestion ... try creating a new user and try firefox on the new account ?

WOW! What surprise! Amazing!
So, you discovered that both
Chrome and Firefox are CPU and Memory Hogs ? Who through that?
What's next? You want to present us a revolutionary round device called "wheel" ?!?

Maybe you could try palemoon or light-firefox, both are available at slackbuilds.org, and see if they use the same amount of resources.

Don't mind Darth Vader... he tends to vent his frustration at random posts on here, without regard to the person he is replying to and whether that information will be beneficial.
As to your issue, you stated you removed the .mozilla/ and .cache/mozilla/ folders, but in your initial output, it is showing that there's missing files from at least the .mozilla/ directory, which seems to indicate that it didn't completely remove your profile. Try creating a new profile using
firefox -p (or create a new user and try launching it from there) and see if that shows the same issues. That can help determine if this is simply a corrupted profile or something more involved.

Thanks for the replay bassmadrigal .
Using firefox from a fresh account seems to have the same problem.
I am going to try light-firefox which Skaendo suggested.

After power failure ? Firefox saves a lot of data (such as browsing history ) using SQLite. One of the databases can be broken due to the power failure.
