it has rich customization features (you can set your letters bolded just like you want). and keeps previous versions with changelogs! although i find dark mode to be somewhat redundant, since it's not the extension's main selling point, but a nice bonus nonetheless, i guess. i second one other commenter's suggestion to make an option to switch from bold to italics or make highlighting use a different font
edit. it also doesn't paste the bold html tags into wherever you're pasting the text from a page into, which is great and what i need
edit 2. ALSO it's available on mobile, for which i must give my separate thanks!

I’ve been using Bionic Reader for a while now, and it has completely transformed my browsing experience! This extension allows me to change the fonts on any website to match my personal style using the fonts I already have installed on my system. Whether I want to switch to a sleek sans-serif or a classic serif, Bionic Reader makes it incredibly easy.

The interface is user-friendly and intuitive. With just a few clicks, I can customize the fonts on any website, and the changes are applied instantly. One of the best features is that my preferences stick around even after I close the tab, so I don’t have to reapply my settings every time.

Bionic Reader also supports dynamic websites, which means it works seamlessly across all the sites I visit. The ability to restore the original fonts with a single click is a great touch, ensuring that I can always go back to the default settings if needed.

Overall, Bionic Reader is a fantastic tool for anyone looking to personalize their web browsing experience. Kudos to the developer for creating such a versatile and reliable extension!

This is a really sweet Add-On. I've been looking for a text formatter to use with Outlook Web, and this is the only one I found that works well.

In an ideal world, I would have liked the Dark mode to follow the Text Formatting. The Text Formatting can be applied to specific Webpages, but Dark mode must be applied to all Webpages.

It would also be a great enhancement to have customizable Hotkeys. Unfortunately, in my circumstance, two Hotkeys that I use a lot come in conflict with Bionic Reader: "Ctrl + Alt + =" and "Ctrl + Alt + -", which I use in Google Sheets and Excel to "insert rows/columns" and "delete rows/columns".

I will say however, this is a Kicka* Add-On. Kudos! Very well done.

Having some trouble with the extension inverting the bold, resulting in the end of the words being emphasized. Not sure if this is a known behavior with a workaround/inbuilt fix, but aside from that seems a good extension.

Follow on edit: Figured it out. If you adjust weights appropriately and the strength, it will de-emphasize emphasized content in pages, while also not effectively emphasizing other content due to the limits it has been provided.

Surprise, the 'issue' was once again the user, not the product.

My bad for assuming this extension was malicious - it works great.

works

Great extension, thanks for sharing it, mind sharing repo so we can watch for new PRs? Thank you

Great extention. Compared to the oringinal BR app is that it keeps the webpage in tact. It would be gread if this extention can also be made for Chrome.

Works more consistently than the other two I tried... Also nice customization
