[questions about functionality]

I get the following warning when I try to install the extension : "Malicious extensions may cause problems and invade privacy." I prefer not to install it as long as'm not sure it's completely safe. One of the main reasons I like the old Opera is that I've never needed extensions or add-ons for it because everything was built-in.

For "Fit to Width" look at these screen dumps before and after enabling the function.

1) text isn't wrapping and can't be read without a lot of horizontal scrolling : http://img8.pixhost.org/images/143/34221976_too-wide.gif

2) text wraps and no horizontal scrollbar is needed to read the text : http://img8.pixhost.org/images/143/34221973_fit-to-width.gif

This happens only with smaller sites that have designers who don't know much about HTML.

Most people think Javascript isn't a threat but I know better. I just give a few articles about past problems and the incidents are increasing with time :-

[Many Chrome browser extensions do sneaky things - Computerworld - Opera]
For example, extensions can intercept Web requests from the browser and modify traffic and inject JavaScript into Web pages.

I might be a control freak and a bit paranoid, but I want to keep security risks as low as possible. I know many people don't care about their privacy or malware but I do. I enable JavaScript only when strictly necessary. I choose sites on the basis of their content and navigability. Most of the time JS isn't necessary at all. For instance, the m-version of Yahoo works without JS on my PC.

@BugMiss006 

I'm sorry I didn't see your feedback at first.

1) Very well hidden, but I found it. Solved. Thanks.

2) ?

3) I mostly hide images because I'm very distracted by images when I'm reading. I'm also allergic for all types of advertising. A third, minor reason is that sites load faster without the images. In Opera 12.14 I can completely disable the caching of images and that feature also increases performance and lifetime of my disk. The old Opera has many features concerning the handling of images. The context menu function allows reloading/viewing any selected but blocked image. You can put a button in the toolbar that allows you to unblock all images on a page at once. There is also a setting for the blocking of animated graphics. Etc.
Maxthon has an adblocker, I use OpenDNS with malware blocking set in the dashboard and a Hosts file (found in C:\windows\system32\drivers\etc) with more than 13 000 malware/tracking domains blocked. The latter is updated by Hostsman, but I included domains I consider as spying sites such as Facebook and Google. All those measures are good but insufficient, because I still get the images/ads of the websites I visit themselves.

Thanks for the reply, but I don't need a script editor or style sheet. The page you refer to is in a language I don't understand.

1) If I find no solution for this, I'll re-install Maxthon and no longer login as I don't see the purpose of it. I'll lock my screen as soon as I leave my computer for a moment.

2) ?

3) not possible

4) ?
