<Solved (for now...)> "Web Content" process running from Firefox

[LamphunLumyai]

Kernel: 3.13.0-37-generic x86_64 (64 bit)
Desktop: Cinnamon 2.8.8 Distro: Linux Mint 17.3 Rosa

Today I noticed a process called "Web Content" that was pegging the CPU cycles and making Firefox dog slow.

Code: Select all

/usr/lib/firefox/plugin-container -greomni /usr/lib/firefox/omni.ja -appomni /usr/lib/firefox/browser/omni.ja -appdir /usr/lib/firefox/browser 2672 true tab

Has anyone encounter this before. It seems to be something new since I've updated Firefox to v49.0. I never noticed it before.

What are your add-ons?

Does this process stay open, if you close Firefox completely?

Click in Firefox the menu (sandwich) icon -> help icon -> restart with deactivated add-ons, then open the same tab(s). Does this process still show in the list?

This is just odd.

I was using System Monitor to look at the properties of the Web Content process. As I was doing this, System Monitor closed down by itself. This was just after posting this topic. Since then the "Web Content" process has not appeared again as I monitor the system with System Monitor continually now.

I've checked my update manager for foreign sources and noticed two. One was related to flash. The options for the command that fired off "Web Content" seem related to flash. Coincidence? Don't know. I've removed both packages which I don't explicitly remember installing.

Code: Select all

mint-flashplugin-steam 11.2.202.460
libcinnamon-desktop0 (2.4.2+rebecca)

After which I've run PPA-Purge.

We'll see...

You could check if you installed those packages off the cronology of Synaptic.

BTW I had the same problem when installing flashplugin-installer in place of the pre-installed Adobe flash packages. Reverting that change, everything looks solved and the Web Content seems quiet.

what worked for me was disabling extensions.

Probably new versions of Quantum will solve this.
