Iframes? What year is this?!

They should consider integrating adblock into the client. Would save a lot of resources not having to run it as a script.

This is an old article but still relevant;

"It turns out that Firefox will by default automatically adjust the number of history pages PER TAB. The adjustment is such that for most of the modern computers, you will store 8 history pages PER TAB. This is clearly not appropriate for people like me who like to have upwards of 20 tabs up in Firefox."

in my opinion Adblock Plus should be avoided for their business model (whitelisting ads for a part of the revenue) anyways.

better use AdBlock, i can also recommend Adguard: http://adguard.com/en/welcome.html 

20 tabs is nothing, minimalists should be running 8gb of ram.  I'm burning a truly absurd 580MB with palemoon here thanks to plugins and history, but it means absolutely dick.  I've got over 26GB free.

I've found one way of keeping memory down in Firefox while still keeping and saving many tabs is using the BarTab extension. Basically when re-opening firefox it doesn't automatically load any of your tabs until you actually click on them. I've found it to be a decent compromise, and have been using it for a year to two now I believe.

Definitely interesting to hear about Adblock Plus. Thanks!

I found another way of reducing memory usage by Firefox several years ago...........uninstall it. 

And use IE or Chrome? Are you mad?

You can turn off the whitelisting so it's not too bad.

sure. but it reminds me of ransomware. personally i would not install software from a company that uses such practices.

Why not use the Whitehat browser. No adds, no tracking, no keeping download history or cookies and WC is automatically whitelisted. The only thing with Whitehat is that you can't comment on skins but you can in the forums. Beats the heck out of FF. No memory leaks, no high cpu usage to speak of and no addons.

I'm mad.  They're the only 2 I use.

Originally it was Opera...but that was a decade ago...

Well then. It's never going to be over!

How can the fat lady sing if there's no Opera?

Ransomware is stuff that charges you for this, not just a simple click-off. 

Opera's still around and kicking. 

I'll be so glad when the ad market crashes for websites, even if it means many sites go to a pay model.

and this is what they do. they block the ads, and charge the ad provider (site owner, etc.) to whitelist them.

for the end user this hardly makes a difference. it still seems shady to me, and as the plugin has (else it wouldn't work) access to all your browsing, it might be worth thinking twice giving your personal data to such a company.

Ablockedge is not bad,either. AdBlock and  Adguard are not strong as AdBlock  plus.
