Why firefox behaves so weirdly/annoying?

Occasionally FF starts very heavy activities, performing huge amounts of I/O (On my HDD) and considerable CPU usage for a long time (More than 10 minutes is really normal for it) that there is no apparent reason for it and can't be stopped easily. In the meanwhile my PC gets very slow and Firefox itself almost hangs. Very frustrating!



It continues even after closing Firefox for quite a while.



FF really behaves like a heavy antivirus program while performing a full HDD scan!!



I am using FFv60 on Windows7, but have experienced the same problem on other PCs with different FF versions and OSes.

  • I wonder if you have a hard disk and your FF is swapping?

How to calibrate 16:9 built-in touch-screen to a 4:3 resolution?

Image
up vote 0 down vote favorite I need help with an issue we're facing in a project where we are moving from a Windows-based POS environment to one running on CentOS7. The problem consists of a number of factors, please find the details below: The supplier of our POS application will only deliver an application that is hard-coded to run in a 1024:768 4:3 format. The hardware we are using is a POS unit from HP that has a built-in 16:9 touch-screen. The employees using this solution is not supposed to see nor have access to anything but the POS application. Our sales organization demands that touch is an available feature when going live with the new POS environment. Going further into this, allow me to explain what we have encountered on the way trying to achieve the goal of having a touch-screen: We've simply change...

QoS: MAC-Priority for clients behind a repeater

Image
1 1 I've setup a wireless network using a Linksys-Router (DD-WRT) as an AP and a TP-Link repeater for range extension. To manage bandwith for specific users, I've setup QoS-Rules on the AP (DD-WRT) using MAC-Priority: However the AP shows only the Repeater's MAC and the MACs of users inside the AP-Range. The MAC addresses of users behind the Repeater are not listed : The purple MAC is not listed in the AP-Clientlist. Its related to a device connected via the TP-Link repeater. Q: How can I setup MAC-Priority for repeater-clients? Do I simply add the purple MAC in AP-MAC priority list although it's not listed as a client? I want to setup specific priority instead of giving one priority for all clients behind the repeater by adding the repeater's MAC in the MAC priority list in the AP as ...
