    Finally, the perfect tool I've been searching for! If you're looking for a quick and clean way to handle selected text, this is it. What it does: Select any text — and the popup appears right next to your selection. Works with any selection method: drag with mouse, double-click a word, or triple-click a paragraph. It's rare to see such attention to different workflows. One-click copy — exactly what I needed. No extra menus, no right-click hassle. Easily switch search and translate engines from the settings. Want Yandex instead of Google? It's already in the list — no need to ma
    morenually dig for URLs or mess with custom search strings. Just select and go. Citation made simple: when copying, it automatically adds brackets and formats the text. No more switching keyboard layouts just to get a proper quote. For those working with AI tools: it adds an extra paragraph break when needed — one click and your text is ready to paste into ChatGPT, DeepSeek, or Giga.chat and any other service. Character count — the popup automatically shows how many words and characters you've selected. Small detail, incredibly handy. Deep customization — the settings are surprisingly rich and varied. You can tweak almost everything: appearance, behavior, which icons appear, and how they work. For a perfectionist (and yes, for a nitpicker like me 😄), this is pure satisfaction. You can make it behave exactly the way you want. Everything works right out of the box, no complicated setup, and it doesn't slow down your browser. After five days of testing various browsers and extensions, this one is a breath of fresh air. Big thanks to the developer — you've created something genuinely useful! 👏 If you're tired of copying via right-click or hunting for search options, just install this. You won't regret it.

    Не понравилось то что перевод текст открывается в новой вкладке. Мне удобнее во всплывающем окошке. UPD разобрался, при наведение курсором на кнопку появляется перевод

    Fantastic Add-On with great functionality, but does not work with Touchscreen devices. The Add-on works perfectly if i use my touchpad. With Touchscreen I can make the Add-on Popup appear by double tapping a word, but it disappears the moment i extend the text selection by dragging the caret. I tried disabling the touch friendly Firefox caret in about:config but could not fix the add-on. PS: In Response to the Developer: Thanks for your Answer. It is possible to simulate Firefox Touch Text Selection by going to about:config. Set layout.accessiblecaret.enabled to true and layout.accessiblec
    morearet.hide_carets_for_mouse_input to false. It would be fantastic to get this working.

    Thanks for your review. This extension only supports mouse click events. Touchscreen support is not stated anywhere in the extension description, and it will not work without deliberate implementation by me. If you want to request adding this feature to the extension, then I don't see it possible because I don't have a computer with a touchscreen for debugging and testing.

    So far works great. I needed a simple extension that would quickly help me with converting units from Imperial to Metric when cooking and this extension does that perfectly. It has a lot of other features but there are way too many for me and I got a little bit overwhelmed by them so I turned them all of

    Current Review (8/5/2024): I'm back to giving Firefox a full time go again (Thank you Google & Manifest V3), this time using Floorp (a great fork!) and I finally got this addon working how I like it to. I'm not sure where I went wrong last time, but this time I exported the addon settings I was using in Brave, and imported them in Floorp, and everything is working as intended. I'm using this on my Surface Pro 7 tablet. This and the Glitterdrag Pro addon makes for nice and lazy one-handed browsing for when I'm watching TV. I'll be installing these on my desktop at some point as well. A fanta
    morestic addon with tons of options. Previous Review (About 4 months ago): I'm switching over to FF from Chromium based browsers. I tried out Opera a few weeks ago and loved their text highlight menu and found this for the other browsers. I'm glad this is here for FF, but it won't let me change the custom tooltip colors. My choices don't save.

    Hi there! I’m sorry to hear that you faced difficulties on changing the extension settings. If I remember correctly, Firefox might have a bug that when you open color picker window, the options popup closes, resulting in color picker result not catched by the options page. Could you please try to open extension settings in a separate tab and verify if the colors are saved correctly then? You can do it by clicking a button with arrow in the top right corner (it should say something like «Open in new tab» on hover). If I guessed the reason of your problem correctly, then you should be able to change tooltip colors on this page without any problem.

    Great extension! Suggestion: Add a submenu to customize order of the buttons

    I wish I could have this outside of a web browser too, it's that convenient.
