Between a rock and a hard place...

[MozillaMonkey]

That's where I'm stuck!

Had been using Ublock Origin as an ad blocker, as recommended by
many here.

The app itself states:
"Finally, an efficient blocker. Easy on CPU and memory."

Yes it was a very efficient ad blocker.
However it wasn't easy on CPU and memory.

I got tired on Firefox slowing down so much that I disabled Ublock Origin a few days ago.
It helped a bit.

HOWEVER, I am now getting quite annoyed by the nerve sites have with their ads!
In the ol' days they used to annoy you with their ads to the right of the screen.

Then they made those ads start to flash and blink etc.

Now advertisers are inserting videos in the middle of the screen that start playing
as you are trying to read an interesting article!!!

Any suggestions?

You can try other adblockers if you like. However, the best might be to tweak ublock origin. About half of its filters are "cosmetic" filters that you might not need. On a slow computer, in ublock origin settings, the filter lists tab, set to:
auto update filter lists - either yes or no, your preference
uncheck "parse and enforce cosmetic filters"
check "ignore generic cosmetic filters"
With those options, the number of filters in use should drop by maybe 40,000. That could help. If not, you may be able to uncheck a filter list or two. The others can be nice, but if you use only easylist you should still see many less ads and processor load could be less.

I am not aware of any performance/memory issues with uBO.

How exactly, in details, did you come to the conclusion "it wasn't easy on CPU and memory"?

Provide these details please so that others can confirm your findings.

uBO is equipped to handle even hundreds of thousands of filters -- we shouldn't assume that OP's findings are grounded unless he provide details for others to reproduce the same (objective, measurable) results.

Is this era of webextensions, that might be a questionable tactic.
(I by chance did an AMO search earlier for, 'ad blocker', & then 'ublock'. Based on the results I'd be wary of the "imposters". [AMO is rife with that, crud.])

Thanks lasardo I'll mess around with its filters a bit if I can figure them out.
I'll see if that helps.

Hi mightyglydd.
Thanks for your help!

Yes I did create a new test profile as suggested, a while ago.
It worked great. It sped things up really nicely!

However after a while I needed to put back the ad blockers, etc.
Once I did that it was back to the same slow browser.

I don't have any utils to measure specifically the CPU/memory hit my computer is taking.
However anecdotally I know that without UBlock things are moving much faster than with it.

As you probably know, I'm still on WinXP, which probably plays into this.

You've just been told by the uBlock Origin DEVELOPER (gorhill) that's likely NOT causing your problem.

(My XP, 2GB, Intel e4300, [SeaMonkey, akin to FF 52] + NoScript + uBlock Origin + other extensions, no issues I'm aware of.)

[lasardo]

I do love ublock origin and I agree I wouldn't trust most of the other results for ad blockers that are on addons.mozilla.org .
