Some advice for easy installation of my extensions
Unfortunately you cant install the extension directly by opening the download link in Opera, Chrome, Chromium, Vivaldi and others. That is a restriction by Chromium developers which i cant influence. And i dislike to upload to Google or Opera Web Store, i have my own repo for my programs.
But... You can install my extension by downloading the extension, opening the browsers extension mananger with Ctrl+Shift+E and dragging the downloaded extension file into extension manager.
And if you try to install one of my extensions the first time, Opera shows a popup blocking installation. Why? Because installation of extensions can only be done from trustful sites as Opera says (thanks, Opera !, i like your strange behaviour and distrust! But my website is trustful!). With Opera that procedure should work and must be done only one time. Sorry for the inconvinience, but please complain to Opera ASA in Norway for such disturbing feature.
Mozilla installs directly from download link.
If you download from link please use "Save As" in download save popup dialog. That is a Chromium restriction since Vivaldi 2.6
Vivaldi, Opera 15 and newer, and Chromium like browsers need a update by hand. Sorry, this is a new Opera and Chromium restriction! Please complain to Opera ASA and Chromium devs.
Start Extension manager with Ctrl+Shift+E, hit button Developermode and hit button Update Extensions now.
On Opera 12 the extension is updated automatically without any need of manual interaction.
On Mozilla Firefox the extension is updated automatically without any need of manual interaction.
Open Extension manager and near extension SearchenginePreview press the tool button to change settings. As a alternative you can activate settings by opening context menu on extension button.
After the settings window has opened, you can easily change the mode for the preview and hide the extension button in toolbar if desired.
This extension adds thumbnails of domains in result pages of a search engine.
These thumbnails are generated by a external service, which uses some data from the results page.
Data send to this service is scheme (means http(s):// part) and shorted URL (only domain name part) and requested size of thumb image.
These external URL are used (an explanatory example):
If you start a manual update check for the extension in Extension Managr some data will be send to gwendragon.de.
gwendragon.de/repo/tools/browser/extensions/searchengine-preview/1.4?os=win&arch=x64&os_arch=x86_64&nacl_arch=x86-64&prod=chromiumcrx&prodchannel=Stable&prodversion=67.0.3396.87&lang=de&acceptformat=crx2,crx3&x=id%3Dcjcekffpdbgaealgkhgmiccgdobfcbde%26v%3D126.96.36.199%26installsource%3Dnotfromwebstore%26installedby%3Dinternal%26ucYou can see the following data:
- Operating system
- Architekture of browser
- Version of browser
- UI Language of browser
- Id of Extension
- Version number of Extension
- Installation source of Extension
For the update the version of the extension and the name of the browser is used to determine if there exists a newer version.
This data is only used for the update check and no profiling or tracking is done.
If you do not agree to these terms, you can not use the extension and are advised to remove it from the browser!
Localization to other languages
For Opera 12 extension every language uses its own HTML files for Popup and Settings window.
For Opera 15 + Chromium extension every language has a own translation file with keyword and translated string. The JSON file is read at start of extension and replacement of translated strings will be automatically done.
Please read about Mozilla i18n and Chrome i18n for file format and information about translation. And please look into the source of files for localization (messages.json, options.html, popup.html) to have an idea about what you can do.
If you like to help me with translations, don't hesitate to contact me in in my blog or by mail. Translators will be made visible in extension's popup, with name or nick and a link to their own webpage, and in changelog. I'm sorry, i can't afford any money for translators, but i'm willing to help you in case of problems with Web programming or design. Perhaps, if i receive very useful help from you, you may get a Gift card which can be cashed in online on Amazon and others.
