I’ll post it after going home.

Half of that memory is being taken by the GPU as visible in Firefox task manager.

I haven’t seen an ad since the time I installed uBlock Origin from Firefox store.

Indeed it is.

I’ll check that out. Thanks.

I’ll try that out. Thanks.

Thanks. I’ll try that out.

Thanks for the link. I’ll check this out at home.

Thanks for the reply. I’ll try out your first suggestion. Btw, I use uBlock Origin, but it isn’t visible in the list. Will edit in the post.
