Firefox is lagging horribly and I'm not sure how to fix this. What do you advise?

Posted

I have an Acer Veriton X2611G Windows 7 machine with 4GB of RAM.

I switched away from Chrome as a main browser as other users have complainned about performance issues.

Since then, I've found that Firefox has become laggy with more recent versions.

A lot of RAM seems to be eaten up for a browser.

Sometimes I have to turn my machine off because running Firefox and another program can lead to the machine becoming unresponsive with a lot of seeming disk chatter.

All in all, it seems that my machine runs less smoothly when Firefox is open.

Has a decision been made to ignore the userbase that doesn't have recent machines?

P.S: Please avoid Level 1 support type answers. I used to be a PC technician and kindly ask that you respect my time and yours.

Hello,

Firefox was smooth after a reset.

I cannot confirm but the culprit might be Lastpass as it was the only extension loaded afterwards.
