The problem I encounter when accessing Twitter is not that of redirecting to the Twitter mobile site. This redirection does not happen.

I think everyone here knows it, but the problem I am talking about is that Presto Opera 12 cannot display the Twitter screen properly:

When accessed with Firefox 45.0, the Twitter screen looks fine like this:

But when accessed with Presto Opera 12, the Twitter screen looks like this:

It is also difficult to send a tweet from Opera 12 because of this. So it is necessary to access the Twitter mobile site to send a tweet.

If this problem with Twitter is resolved, I don't need Chromium Opera at all. Presto Opera 12 is good enough for me.

For me, the only problem with Presto Opera is the problem with Twitter. If it does not have that problem, I don't need Chromium Opera or any other browser for that matter.

As for Netscape, about the only websites online that can be viewed with Netscape may be mine. I design my websites so that they can be viewed with Netscape 7.0. All of them work all right with any other browser and are ranked high in Google.

Posted with Netscape 9.0.0.6

Below is the one I use:

Machine: ThinkPad T43 (Model: 181734J)

CPU: Intel Pentium M 1.73GHz

Memory: 2GB RAM

Maybe, my computer is too old and too slow.

Also this forum sure has an editting option. I have just checked it out.

There was a typo in my previous comment:

[incorrect] Chrominium

[correct] Chromium

By the way, it takes about 5 to 8 seconds for Chromium Opera to display my bookmarks, which number around from 5000 to 7000.

I must say this is too slow.

Opera 12.18 is a great news, only it is just a security update. I want to use Presto Opera on Twitter, but it still cannot display the Twitter screen properly.

I installed Chrominium Opera for the second time today, but it is too slow to display bookmarks. I don't think I can use it. A big disappointment.

@lem729

The number of my bookmarks is not 500. It is 5000, that is, FIVE THOUSAND. Opera 20 does not seem to be able to properly handle this many bookmarks.

I already had around 500 bookmarks a year or two after I started to browse the Internet for the first time. That was a long time ago. Most of the people living in Japan did not access the Internet at that time, and Bill Clinton was still having fun with his secretary at the White House if my memory serves me correctly.

Thanks for telling me about the Bookmark Importer, lem729. I have just tried it, but it has a few probelms.

1. Some bookmarks are shown in the bookmark tool bar, and the rest of them is all hidden. There are a few problems with this.

It is inconvenient to get to the hidden bookmarks because it takes extra time, and this extra time seems a little too much.

Another problem is when I show my computer screen to other people. My bookmarks are basically secret. I do not want to show them to other people, but they are in the bookmarks tool bar so everybody can see. I often show my computer screen to students in my class. You can imagine an awkward situation when I do it with Opera 20.

What I need is the same bookmarks system as the one in Opera 12. That way, you can hide your bookmarks easily by using folders.

I have found that the same thing can be done with Opera 20 too, by dragging and dropping bookmarks folders into one folder. But it takes a lot of time to open this folder, and it is too inconvenient. "Over 5000 bookmarks" is not a joke; it is true, and a folder with 5000 bookmarks and a lot of sub-folders seems to work too slowly. Also I do not like the way bookmark folders work: it is just like Firefox bookmark folders. Those Firefox bookmark folders are terrible when you have hundreds of bookmarks in one folder: it takes too much time to go through bookmarks from the top to the bottom.

I need to go through thousands of bookmarks quickly and efficiently every day. So far Opera 12 is the best for that.

2. Bookmark folders open too slowly when thousands of bookmarks exist in them.

This is what I have just talked about.

The only problem with Opera 12 is speed, not functionality, I do not want Opera to change functionality. In any case, the reason I use Opera 12 is its functionality, not speed, and I am satisfied with the functionality of Opera 12.

In conclusion, the Opera 20 bookmark system is useless.

I have just tested the latest Opera 20 and have compared it with Opera 12.

Missing Important Features:

1. Bookmarks -- I have over 5000 bookmarks in Opera 12. They are just gone. An extension called "Bookmarks Manager" can import bookmarks from Opera 12, but this extension is considerably more inconvenient than the Opera 12 bookmark system. Without my bookmarks I cannot access some of the important websites I need to visit, especially my own 300+ websites. What a pity that I cannot visit MY OWN websites!

2. meta redirect control -- "Meta tag redirect" is used to redirect visitors from old websites to new websites. This happens when you move a website to a new domain. With Opera 12, you can always visit such old websites. This feature has proven to be very useful when you are in the process of moving a website to a new domain. I own quite a lot of old websites. So, if I stop using Opera 12, I can never go back to my old websites.

3. MHTML web page saving -- You can save a web page in ONE MHTML file with Opera 12. I have saved thousands of web pages in the MHTML file format with Opera 12. With Opera 20, you cannot save a web page this way, and you cannot view your archive of web pages saved in the MHTML format anymore. MHTML has been so useful, and I cannot give it up.

4. Default font set -- The default font set is MS P Gothic (for Japanese-language websites anyway) with Opera 12, but it is Times New Roman with Opera 20. No Japanese use Times New Roman in Japanese, of course. As a result, Japanese-language websites look very strange, not the way they should look. This can be adjusted if you do a few things in the settings, but it is hard to find where to look.

Good things about Opera 20:

Opera 20 is certainly faster than Opera 12. But that is just about it: there is nothing else to praise.

Bad things about Opera 12:

With Opera 12, you cannot tweet on the PC version of Twitter, and you cannot follow or unfollow other accounts either. You need to access the mobile version of Twitter to tweet and follow / unfollow other accounts.

My own decision:

I will stick to Opera 12 at least for now. When I need speed, I will use Firefox. I cannot part with Opera 12 because of the first three problems I mentioned earlier. When I need to access Twitter, I will use Firefox or just access mobile.twitter.com with Opera 12.

By the way, I prefer to use Opera 12 especially when I write articles for blogs, because Firefox often deletes all my writings and I have to write the same things all over again.

There are so many things that make me continue to use Opera 12, but there is none that compels me to use Opera 20 or Firefox, or for that matter, Chrome.
