anyone had this problem?

[donvan1]

After the last few Firefox upgrades (above v6.x) I notice that my mouse (Logitech wireless) seems sluggish at times. It does work but seems to lag for a short time when making multiple clicks on a web page...such as making a selection and then a back arrow in too rapid of succession. The pointer doesn't seem to be highlighting the selected item when positioned over it, and multiple left clicks do nothing. If I move the mouse pointer about the page for a while Firefox seems to catch up and respond correctly. This happens often enough to be slightly annoying. Using the updated KDE desktop.

Check your batteries....

Batteries were the first thing I looked at...new batteries.  Also I checked the mouse settings in system properties and the battery monitor shows @ 70% charged.

Is it only Firefox or is it doing it elsewhere as well?

Hit CTRL + ESC , it might be a addon that is hogging all cpu power

[donvan1]

menotu, sorry for the slow reply....yes it only appears to be happening in Firefox...perhaps I'll begin by shutting down some of my add ons one by one.

demilord, I could see no excessive use of any system resource when I hit ctl + esc keys...cpu usage was @ 4% most of the time.

Which DE/GPU/Kernel?

Try FF in safe mode:

Code:

firefox --safe-mode
