Please GeraldSmallBear, provide technical details of your OS and your Opera version/setup, and people might me more inclined to assist you.

fungi-lives,
Very often the setup of mine does not crash either, especially right after boot or opening Opera, but when I leave the window with 6 tabs open for some time, say 5 or more minutes or so, and I reload all tabs or just reload the single bloomberg tab, then Opera crashes. I have exactly the same problem on my older computer too (WinXP, Opera 12.16, all 32-bit).
On all computers, I got the latest versions of Flashplayer, Java, and other plugins.

I just found out that bloomberg.com makes O12.16 32-bit on a Windows XP 32-bit machine also crash. The solution is the same as on the 64-bit version, that is, disabling Javascript in the Site Preference for bloomberg.com.

Windows 7 64-bit
Opera 12.16 64-bit

I got an Opera window open with the following tabs:
http://www.ft.com/home/uk
http://money.cnn.com/?iid=dmstedition
http://www.reuters.com/
http://www.bloomberg.com/
http://www.dw.de/
http://www.spiegel.de/

After having the window open for several minutes, Reloading All Tabs, or reload only the bloomberg.com tab, causes Opera to crash.

It turns out that it is the bloomberg.com tab that causes the crash in my case. I figured it out by disabling JavaScript for the bloomberg site:
Menu > Settings > Quick Preferences > Edit Site Preferences ... Go to the tab Scripting, then tick the box [Open console on error], just to see what errors are flying by upon reloading bloomberg.com, and Untick the box [Enable JavaScript].

Once JavaScript is disabled in the site preferences for bloomberg.com, the Window with its 6 tab does not crash anymore. Nonetheless, I noticed in the Error Console that there are a significant number of JavaScript error flying by from all tabs (sites) but these do not crash Opera, except some JavaScript errors from bloomberg.com.

I was wondering if anyone could reproduce the Opera window with the 6 tabs (sites) and see if the window also crashes upon reloading all tabs, or upon reloading only the bloomberg.com tab?

Internet Explorer 11 does not cause any problems. So, at first sight, it looks like Opera is not "robust" enough against the javascript errors coming from bloomberg.com.

thanks,

Done some research, and indeed, it looks like there is no 64 bit version available (yet) for 15+; what a disappointment! Is it not evident that 64 bit is main stream? Just wonder what Opera's plans are for any 64 bit version?

Opera can be downloaded from:
http://www.opera.com/download/guide/?os=windows&list=all

Opening in new tab the latest O15:
http://www.opera.com/download/guide/?os=windows&ver=15.0.1147.153&local=y
offers me the opportunity to choose between 32 or 64-bit

However, for O18
http://www.opera.com/download/guide/?os=windows&ver=18.0.1284.68&local=y
there is no option to choose between a 32 or 64-bit version.

Furthermore, the download page does not mention whether O18 is 32 or 64-bit.
Least thing Opera should do is mention very clearly/explicitly on their download page weather O18 (and O18+) is 32 or 64-bit.

So, is O18 then 32 or 64-bit? If 32-bit than this is a major step backward.

Ok Pesala, I'll start doing testing soon. Based on your response it looks worth while to put some effort and time in testing O18.

Hi,

I'm still using Opera 12.16. At the time 15 came out I Googled the Internet and realized upgrading would come with a high risk from the point of stability and usability. 12.16 is great, very efficient Bookmarks system, Sessions are just great, overall fast (enough, still), ...

MULTI-THREADING
----------------------
However, 12.16 has one big disadvantage: it's single-threaded! My computer has a processor that comprises 4 cores, each 2 threads, so 8 threads, and Opera 12.16 just runs on a single thread. As a result my sessions, with 20 to 40 tabs, run a lot faster on Internet Explorer 11, than on my O12. In IE11 each tab has its own process and consequently all tabs are distributed over all threads in the processor in a fashion that all 8 threads are pretty much equally loaded; this can be seen in Task Manager. Compared to O12, this makes IE blazing fast, and you can see that in the Link Speed in Task Manager->Networking; the link speed is saturated when opening a Folder with 10 to 20 favorites in a tab Group: that never happened when opening any of my sessions in O12.

So, what about multi-threading in Opera 18? Or is O18 still single-threaded?

SESSIONS
-----------
The Sessions Feature in O12 is great. It does not exist in IE11 but you can emulate O12 Sessions in IE11: put all your favorites in one single folder. Then open that folder in a tab Group, and all favorites in that folder open at once in the correct order as they appear in the favorites folder. And you can open several different favorites folder in a tab Group mode in different IE11 Windows, thereby emulating several different O12 sessions in different browser windows. Great!

But what about sessions in O18? How much better or worse is it in comparison to O12?

BOOKMARKS
--------------
From what I read on the Internet, O18 bookmarks are not all that great and it seems O18 has made a step backwards compared to O12. But just how bad is it? I got a huge number of bookmarks and I really need to maintain oversight.

Time to decide
------------------
Recently I got problems with www.bloomberg.com . My O12 crashes when I reload all tabs of the session where bloomberg.com is in. In IE11 all is OK, no crashes on bloomberg.com. Also my other sessions in O12, where bloomberg.com does not appear, do not crash upon reloading all tabs.

Considering that O12 will probably not receive any security updates anymore, I might have to move away from Opera, unless O18 is multi-threaded and has a speed advantage after all over IE11.

So, your comments on previous questions would be very much appreciated. Depending on the response to previous questions I'll see if I find it worth testing O18, or just move right away to IE11 or maybe even another browser.

Thanks,
johan
