Had a bit of time to mess around with Opera this afternoon. I did a clean install of Opera 12 Final, it seems to run better than before although there are still glitches. I also installed the latest Opera Next snapshot, which also runs a little bit better.

I was looking through some of the bug reports on the Opera site, users have posted links to sites that they say don't load or render correctly so I tried a couple and got the same results, pages didn't load correctly. So I decided to disable the extensions I have installed and try the pages again. This time they loaded.

I have three extensions installed - WOT, Up For Everyone, and Opera Adblock. Tried them one by one and noticed that the extension causing the page loading problems, for me, was Opera Adblock. When that extension is disabled the problem sites load. So it seems to me that Opera may be suffering from the effects of third party add-ons in some cases, problems similar to other browsers that support add-ons / extensions.

I still have issues on some sites, mainly ones containing video [stuttering playback and tabs freezing] - although uTube seems to work fine. And I also have issues with rendering maps on the Garmin site I use, issues which I don't have with any other browser on that site.

Memory still ramps up high when using the latest Opera, but using the old trick of minimising the browser to the tray then re-opening it knocks memory use back down again. That doesn't worry me because I have plenty of RAM, but even so, Opera has become more resource hungry from what I can see - both with XP and Win 7.

I hope they take their time to iron out the glitches before releasing any more updates to the Final version. I decided to clean install Opera 12, thinking that maybe too many over the tops in the past could have been the problem. Doing that appears to have improved performance but, as I said, I also think that the Opera Adblock extension is causing some problems.

I find Opera Adblock causes a fair number of problems with loading of pages for me too. It was much the same with the later versions of Opera 11. For a while now I've have been using the Opera Adblock toolbar button to disable it when a page doesn't load properly, and in many cases it does indeed seem to be the main culprit.

It's hard to blame these on the Adblock extensions as a whole. Remember that these extensions are checking the addresses against thousands and more filters to block the ads by calling the content policies and there could be a few false positives here and there. In that case it's best to whitelist the webpage or even the whole domain. You can also put the blame on websites becauses some of them requires the ads to render the page correctly and blocking these ads would be critical.

It's not necessary that these problems should be concerned with Opera. Until the latest update Flash 11.3 didn't load any videos on Firefox and this news was all over the net to which Adobe apologized later on. If you are not getting videos properly rendered on Opera try updating to the latest patch or downgrade to v11.2. Also there was a issue with the co-existence of Real Player plugin and Adobe Flash. If you're still having problems, hopefully Opera will be fixing them in the next update.

I wonder when will Firefox follow this suit, of minimizing the web browser to reduce memory consumption while not active. Opera 11.5 was lighter than v12, may be this was because plugin processes wasn't separated from the main process.

All that being said, in all the latest tests at Tom's Hardware Web Browser Grand Prix involving the 5 major browsers, Opera seems to lead by a good margin against other browsers in proper page load reliability category since v11. I can see this from personal experience too. Page rendering problems with Opera is a thing of the past. Also for the first time Opera came out as the winner after a long break in his tests, the spot which was usually occupied by Chrome or Firefox.

Doesn't anybody use Fanboy's Adblock List + Optimized Element Filters with Opera? It works better than Opera Adblock for me, though not as powerful, but still cleans out ads well and removes the white spaces too. Also it's more resource friendly than adding an extension for the same.

On the whole, I was pleased when Opera started supporting extensions. Although I don't use many, some of them are useful, WOT being one of them. Opera Adblock has, and does, work well enough for me but I was always happy enough to use the built in content blocker in the past. But as we see with other browsers, extensions / add-ons have to be kept up to date or they can begin to cause issues, then we end up with all the compatibility problems - compatibility reporters etc.

I think Sope has used Opera for a long time, as have I, and he's seeing the same thing with Adblock. What I'm saying is that many of the site related issues, pages not loading etc, that are being reported are probably being caused by that particular extension - and yet users are blaming Opera itself, which is not necessarily the case. It's more likely a third party issue.

Opera always has had page rendering issues, always. Some Websites just don't load properly with Presto, some require you have 'send referrer information' enabled for them to show correctly. But I agree that Opera's overall page rendering has vastly improved of late.

I have the latest Flash, Java etc, installed. But running some video sites, or sites with lots of Flash and heavy graphics causes Opera problems at the moment. This wasn't as evident in 11. Perhaps there are issues with Opera and Flash, but I don't see the same problems when using other browsers on the same sites. Maxthon 3 for example runs video almost flawlessly for me, including using the built in pop-out player. And the only time I've had problems with the maps while using Garmin Connect is when I'm accessing the site with Opera - but this is not new to Opera 12.

No doubt, in time, the opere-plugin-wrapper will improve, it's early days for Opera in that respect. I mentioned Maxthon 3 earlier, but that runs more processes than Opera to achieve it's performance and has taken ages in development to get there so, in a way, it's a bit of an unfair comparison. But Opera seemed, to me, to use less resources in previous builds with just the one process running - opera.exe. And although the latest browsers all seem to claim they use less resources these days, I don't particularly notice it much, so Opera is no different there either.

As stated by Opera, many times, the only way to gauge the browser is to run it in default mode, with no extensions installed. I think the developers, in certain cases, are taking a bit of a kicking from users who are probably using an extension laden Opera, when in fact it may be one or two of those extensions causing the issues. Looking at it again, as I have today, indicates to me that Opera Adblock can cause some sites not to load, which in turn gives the impression that the browser is running slow or sluggish - even causing higher resource use.

Nothing's perfect, and these are just my observations. But I wonder how many users have come across these same issues while using / trying Opera 12, only to dismiss the browser as a poor performer and un-install it?

These claims can be best measured on old systems. On all the latest systems running Win7, having oodles of RAM available and also a graphics card to reduce the chores of the CPU, there's no marked difference in memory consumption among these browsers. This is one of the reasons why I'm left with not much choices, except for Opera and other light weight browsers on my low-end system.

I used Fanboy's Adblock List for a long time before Opera introduced extensions and yes, it did the job well. Once Opera Adblock extension became available I switched over to using that, mainly for the convenience of automatic updates. Hard to know if it's the current Fanboy list that is the cause of certain page loading issues or something else within the extension itself. Suppose I could go back to manually using the old urlfilter.ini method for comparison but it's not that big a deal to me really.
As you say, I suspect it's the way that some websites are integrating ads into their pages that is also a significant factor in this. After all, it's not in their interests to allow people to easily block their ads!

I'm using the Fanboy's list + tracking with Opera 12 (Linux) and it's fine for what I need.

Without Element Hiding Filter's doesn't the white spaces bother you?
