Poipoi555, your not giving much information by just saying "doesn't work", as I have it installed in Opera version: 73.0.3856.344 (64 bit), it works fine.

...but, here is some information to help everyone understand the use of extensions.

Conflicts with Other Extensions?
If you have other extensions installed, deactivate them and check them one by one to see if any one of them interferes with Stylus.

Some Web Pages block Stylus
Some web pages may conflict with, or block Stylus since Stylus is a script itself for it to work. There was one time I had to deactivate Stylus because the web page conflicted with it. Nothing can be done about this. All you can do in this case is work the best with it.

Built-in Browser Pages
Stylus will not work in built-in pages of Opera such as the Speed Dial page or a default Tab page. Most extensions that affect web pages will not work in browser built-in pages.

If this is the case, click on the Stylus icon on the browser top bar and you will see this:

Stylus doesn't work on pages like this.
As a security precaution, the browser prohibits extensions from affecting its built-in pages (like chrome://version, the standard new tab page as of Chrome 61, about:addons, and so on) as well as other extensions' pages. Each browser also restricts access to its own extensions gallery (like Chrome Web Store or AMO).

Hope that helps.

I just tested Stylus in Opera version: 72.0.3815.186 and updated to version: 72.0.3815.200.

I used it:
Current tab - works fine
Opened a new tab -works fine.
Opened New Window - works fine
Closed Opera & tabs, reopened Opera with new default tab -works fine.

InCognito Mode
By default, most extensions won't work in Incognito mode, you have to change the settings for that extension for it to work.

Developer Inspection Window
This is when you right click any part of the webpage and click "inspect element". In the inspection window, you can change any part of the webpage. These changes will never remain on page refresh or new Tab or reopening Opera.

What the inspection window also does, it seems to bypass Stylus. I think because the DOM is affected or temporarily changed by the inspection window, and this affect remains so long as that page remains open. Once it is refreshed, renewed or Opera closed and reopens, Stylus works again.

Saving a CSS Style
I list this out for the benefit of new users to Stylus

• Click icon
• Click "manage" button
• Click "Write New Style" button for a new style (left window) or click a current saved style in the middle window
• Write the new CSS Style. It must be correct in syntax, else it won't work.
• Click save button left window, make sure the "enabled" box is checked and for real time results, check "live preview".
• Use the browsers back button to return to the main list.

Hope that helps, along with what I said above.

@shion-san said in Stylus:

Doesn't work properly anymore.

I still use this extension in the current versions of FireFox, Google Chrome and Opera. It works fine.

If anyone has a problem, then shut off all the other extensions you are using and see what other extension or plugin is causing the conflict.

Note: this extension will not work on any built-in default page templates used by Chrome, Firefox or Opera. These are the "New Tab" built-in default pages that show quickstart icons. The reason is how those built-in pages work and how they are generated by the browser.

ideenic has made a good point which I forgot about.

It is true, many websites now use a data scheme or a data attribute in their HTML source code of a web page to embed images, and "data attributes" tend to include various script methods. This can make downloading the image problematic. So, if the standard "right-click / save image as" command does not work, then take a screenshot and extract the specific image from the screenshot using an image editor like MSPaint, saving the image using the common format of JPG or PNG.

To see what ideeinc speaks about, you can read more here:

Don't use the image URL, instead download the image to your desktop and then drag it into Tineye page or the Google Images page (drag it over the search box of either).

URL's can be problematic, especially when they are too long or contain characters that create issues with servers. Also, some servers are purposely configured to block certain URL requests to stop excess use of their bandwidth and for security reasons. This is why using just the image as I described above is the best way to do an image search.

I have found the same thing happen at Google images, not just TinEye.

At times, the image is not found at Google, but found at TinEye and visa versa. I use both sometimes to see if there are different results.

Keep in mind, some people who make their websites block crawlers from indexing their images on purpose, to stop others from stealing their images.

It could happen that TinEye was blocked from indexing the image(s) but not Google. Either way, never depend on Google or TinEye 100% to locate or match an image, ... yet both provide excellent image search tools.

This screen-capture (still images) extension is pretty good, I use it a lot. It also works well when wanting to capture Google map images, either of the map or of any street-view image (once you click to print it)

This extension is very good, it works the same as Google image search.

I use this exact same extension on 2 of my other browsers, Chrome and FireFox. It is an excellent extension, it allows me to edit how things appear in any webpage that I frequently visit (ie: Google search results). It also acts like an AD blocker, where I can remove popups and elements on any webpage, especially in YouTube where they have these block elements popping up over the video while trying to watch it.

Of course, you need to know CSS coding and know how to use the source code inspector provided by any major browser.
