Firefox Community Forum

Hi Community,

I am writing as recently I noticed that extreme amount of data was written on my system SSD. Here we are talking about 100-200GB of data written daily. In resource monitor I found that Firefox is writing this amount of data in its Profiles folder, but only when Facebook's main page is open. I also noticed that when only the Messenger part is open the problem goes away. Currently I symlinked the Profiles folder onto one of my HDDs so the data is being written there, however I would like to know if anyone experienced the same issue and what could be the solution for this. I completely reinstalled Firefox, my installed extensions are Adblock Plus, Enhancer for youtube and Facebook Container.

Lately, I’ve noticed Firefox consuming more RAM, especially with multiple tabs open. Is this a common issue in recent updates? What are some tips to optimize Firefox performance on lower-end PCs? Would love to hear your experiences!

Hello, I am running win 7. Yes and Old computer. When the system is running slow I do a task manager to see what might be causing it.

I have noticed multiple Firefox processes running with 0 CPU usage. What are all those for and do I need them? Can I disable them?

On a separate issue I am getting this rendering error. This may be a Microsoft question, but I thought I'd ask. Error in rendering player Error Code: 400-404 Session Id: k6x4392p (Pls: 35a725dd-3aac-4813-8431-159ebc196c01)

Lastly I did contact support about uninstalling two Firefox programs. I deleted the one you said.

Thanks again for all the help, Irv

I am a heavy Firefox user, and have been using it (and its predecessor) since Netscape. In the last year, the size of my Firefox profile has more than doubled, from 500MB to 1.3GB. What's the probable cause(s), and what can I do about it?
