Thanks you for the review and the kind words.
Version 1.91 is released. You can now exclude a list of domains by right-clicking on the list of words: a contextual window will appear where you can specify the domains you don't want Mukti Find to try to highlight. I also tried to enhance the performance.
Regarding the interface, it will be revamped soon: the toolbox icons (currently at the bottom of the interface) will be part of the new contextual window.
Stay tuned!

Thank you very much for your review and the 5 stars!
If you're a fan of minimalism, I imagine you've already hidden most of the user interface elements through the Display Options!
Currently, there is no setting to remove the context menu item, but I’m considering adding this feature in a future version.
Thank you again for the great suggestion!

Bardzo dziękuję za miłe słowa i polecenie!

Translation of the review: "A very nice and useful extension, I wholeheartedly recommend it."

Translation of the answer: "Thank you very much for your kind words and your recommendation!"

Great! Thank you so much for your 5-star review!

Thank you so much for your kind words and the 5-star review!

Thank you for your review and feedback! I'm glad to hear works fine for you.

Thank you very much for your review.

Regarding your request, I might introduce wildcard characters in the future, allowing you to separate different words. However, I'm afraid the search won't be able to span across different paragraphs. Stay tuned.

Thank you for your positive feedback and your patience. I apologize for any inconvenience caused by the colour issue, and I am pleased to hear that reinstalling the extension resolved the problem for you.

Version 1.60 introduced the dark theme, this is probably what you were seeing. The theme can be changed in the display settings (default is "system").
At this same place, you can choose the sub-range of colours to be used. It is not very intuitive: you have to click first on the first colour of the sub-range and then on the last colour of the sub-range (click on the first cell and then on the last one to retrieve the default settings).
Thank you for using Multi Find!

Thank you so much for your enthusiastic feedback! I'm thrilled to hear that this extension has been a game-changer for you.
Regarding your suggestion, and I'll definitely look into it.
I appreciate your support and I'm happy to share that a premium version with additional features will be available next year, so there's no need to donate for now.
Stay tuned for the updates, and thanks again for your fantastic support!

Thanks a lot. A new version is about to be released: I am convinced you will love the new features!

From version 1.70 you can edit all the highlight colors, including the dark mode ones. Feel free to make them brighter.

Thank you for the review, and I'm glad that you like the addon.
Regarding the keyboard shortcuts, it is difficult to find one that suits everybody. But the good news is that you can change it. Type "about:addons" in the address bar, then click on the cogwheel and choose "Manage Extension Shortcuts" in the menu. You can then change the key combination to anything you like.

Thank you for for using Multi Find and for your feedback: I am glad to hear that this extension has been helpful for your academic work.
To answer your concerns:
- Unfortunately, regarding the support of PDF, I am afraid this is too complex for this extension (basically I would have to re-write a PDF-viewer). A possible workaround is to convert the PDF into an HTML page.
- I understand the standard selection white highlight masking the extension colored highlight can be disturbing, but it is important to distinguish the current selected word while jumping from one occurrence to the next one, in case several of them are on the same line, for instance.
- And I appreciate your suggestion of the broader search with a random middle part: I will certainly consider implementing a joker/wildcard character in the future.
Thank you again for your support, and please keep checking for updates!

Edit: with the version 1.40 (Oct. 13), you can now activate the soft glow highlights: the color of the highlighs should still be visible even if you select the text.
