I spend a lot of time reading scientific papers, documentation, and educational websites, so I'm always looking for extensions that make research more efficient.

Right now, I mainly use extensions for:

PDF viewing and annotation
Dark mode for long reading sessions
Tab management
Citation or note-taking
Saving articles to read later

Most of my browsing involves comparing journal articles with educational resources on neuroscience and research peptides, so it's common for me to have 20–30 tabs open at once. One of the sites I regularly read is. alongside journal databases and university publications.

I'm curious what extensions other people recommend for:

Organizing large numbers of tabs
Highlighting and saving important text
Better bookmark management
Reading PDFs inside the browser
Improving productivity during long research sessions

I'd appreciate any recommendations. Thanks!
