Thank you for your detailed feedback — I'm really sorry about the problems you encountered.

Regarding keyboard shortcuts: it is possible to assign a shortcut to search for the next occurrence and another shortcut for the previous occurrence (although unfortunately "Enter" cannot be assigned as a shortcut key). To set this up, click the puzzle piece icon to open the Extensions page, then click the gear icon to open the tools menu, and choose "Manage extension shortcuts."

About your comment on matching the default search behavior more closely: I took it very seriously and made two significant changes.
First, in the search window, you can now click the "eye" icon and choose the half-open eye mode: highlights will only be visible when the search window is open, similar to the default search bar behavior.
Second, there is now a new option in the display settings to choose what should be shown when you reopen the search window — including an option to automatically select all the previous search content, allowing you to instantly replace it by typing a new word.

As for the highlight colors: all highlight colors are fully customizable through the display settings (just click the gear icon in the Multi Find window).

Concerning the random arrows appearing on the page: I have fixed a bug that caused unexpected scrollbar arrows, so hopefully it should now work much better. However, please note that scrollbars (and their arrows) can appear not only on the main page but also inside any iframe embedded in the page.

Finally, regarding the extension completely stopping working: I don't have a clear explanation, and I am surprised that uninstalling and reinstalling didn't solve it. Perhaps cleaning the browser's cache could help?

Again, thank you very much for your feedback: it helps me improving Multi Find!

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!

Большое спасибо за ваш отзыв и за то, что нашли время так подробно описать обнаруженные проблемы!
Благодаря вашим точным описаниям, мне удалось исправить обе ошибки: белые полосы вокруг окна расширения в тёмном режиме, а также исчезающую стрелку на встроенных видео в Яндексе и DuckDuckGo.
Ещё раз благодарю вас за помощь в улучшении Multi Find!

Translation of the review: "I liked your extension so much that I decided to write a review about it. While using Multi Find, I found two issues that I hope you can fix in the future.

The first issue is white borders around the extension window when using Multi Find in dark mode on the Yandex search page, even when dark mode is also selected in the extension itself.
The second issue is a briefly appearing and then disappearing arrow on the right side of embedded videos in the Yandex and DuckDuckGo search engines (in the video sections under the search bar).

I am using Firefox Browser version 135.0.1 (64-bit)."

Translation of the answer: "Thank you very much for your review and for taking the time to report these issues in such detail!
Thanks to your precise descriptions, I was able to fix both problems: the white borders around the extension window in dark mode, and the disappearing arrow on embedded videos in Yandex and DuckDuckGo.
Thank you again for helping me improve Multi Find!"

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!

Glad you appreciate this add-on.
Version 1.86 will fix the issue on Ebay. Thanks for the heads-up.
The default shortcut to open Multi Find is Ctrl-Shift-F, but if it does not work, you can change it through the Firefox menus: click on the jigsaw icon, then on the cogwheel menu and choose "manage extension shortcuts". Hope this helps.

Thank you for your detailed feedback!
I'm glad you appreciate the lack of word limits in Multi Find.
I'm continuously working on improving the extension, and your input is invaluable.
I'm aware of the slowdown issue with many words (and long webpages) and am exploring ways to optimize performance (v1.81 should already be faster than v1.80, and you can try to set diacritic sensitiveness *on* to speed up even more).
The reason why there are no different settings per site is that the extension is not aware of the navigation URL, for confidentiality issue. There is for now no plan to change that but the different word lists are on my radar instead. I hope to add this feature in a future update. Thanks for your support and patience!

Thank you for your review and remarks.
I will try to add the option to have no highlight at all in the settings (none/regular/soft glow).
Regarding your second point, unfortunately, I tested this same website, and I did not see any issue with the highlights. I would appreciate if you could, please, send a screenshot to info(at)vgreco(dot)fr
[EDIT 30/09/2024] version 1.83 can now have the highlight style set to none (go in the display options via the cogwheel) and still be able to count and select the searched words.

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 feedback!
Regarding the horizontal scrolling, the extension does not currently support a horizontal scrollbar because most search expressions fit within the window's width. However, I will consider ways to improve this (larger window or horizontal scrollbar).
[EDIT] Horizontal scrollbar added in version 1.74.
As for the search window not closing when clicking on the webpage, this feature was added recently due to user requests for a persistent window. You can revert to the previous behavior by disabling the "persistent search window" option in the display settings (click the cogwheel).

Thank you for your review and suggestions.
I'm sorry to hear about the slowdown issues you're experiencing. I will see what I can do to improve the speed (but is highly depends on the length of the word list and the webpage).
For the profile feature, the upcoming support for multiple keyword lists should address your needs. Stay tuned.
Regarding the color-coding for specific keywords, I'll see what can be done to implement this feature. [EDIT] Version 1.80 introduced color choices for individual words (and a faster search window).
Thank you again for your feedback!

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.
