Firefox using a lot of memory? Could be Adblock Plus

Mozilla recently tested the most popular extension Adblock Plus. It has approximately 19 million users.

Turns out there’s a constant overhead of 60-70 MiB (on a 32 bit machine, it’s smaller, probably). This is due to additional JavaScript memory usage and some extra layout memory.

“The difference is significant, especially under the right circumstances. Adblock Plus adds an overhead to Firefox's memory usage of about 60-70 Megabyte. While that may be a lot depending on the installed memory on the computer, the difference can widen quickly under certain circumstances. For every iframe that gets loaded in the browser, four additional Megabytes are added to the browser's memory usage. That does not appear to be much, but if you consider that some sites may make use of many iframes, it can grow quickly.” – gHacks

On a regular machine, this isn’t a bad trade off. On a low end machine, the picture is quite the opposite, and may really slow things down to a crawl.

So, Adblock Plus will hopefully get some love from its devs. In the meantime, if you hear complaints about Firefox being a memory hog, in truth it isn’t.

It’s Adblock Plus and the site you’re on.

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;

http://annoyances-resolved.blogspot.com/2011/05/firefox-memory-problem-solved-or-rather.html

 

"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.

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

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.

This is really a misnomer - yes, Adblock uses memory - but it also prevents ads from being downloaded/run.  The memory profile, slowdown, and extra bandwidth of those ads makes the extra memory from Adblock meaningless.  Not to mention it's probably one of the best security programs out there in preventing "driveby attacks" (NoScript is better for that of course)
