Greetings again everyone, (especially Bob & Pol)
O.k. - - I decided to take the plunge...on trying out the ublock plugin for FF. After first removing ABP, I installed it "as is" - not changing any of the default settings, lists, etc. (As mentioned previously, I'm a far cry from being an "advanced user").
Shown further down is a screenshot (like Lisandro's) of what ublock shows 24 hours after installation, and visiting the websites/forums etc I belong to + a couple of websites I've never been to before.
One question: With regard to the memory usage comparisons previously given by Pol - - what would be the simplest way to just get a general idea of how much less ublock is actually using compared to ABE or ABP?
If it simply involves looking in Task Manager (Processes tab) at what FF is using, then it appears it's using significantly less memory than before. Previously, (with either ABE or ABP installed), FF was using in the neighborhood of 250,000 - 270,000K, according to Task Manager. Now, the FF usage is between 205,000 - 212,000K (when I checked Task Manager 3 times while typing this post).
So far...so good.
Pete
