Writers who do most of their work in the browser — in Google Docs, Notion, blogging platforms, or plain-text editors — spend hours in a single window. Here are Firefox extensions that support a long-form writing workflow.
Grammar checking without cloud processing
AI Writing Assistant — grammar checking and text rewriting that runs locally in Firefox.
For writers working on sensitive content — personal essays, work in progress before publication, any content you don't want on a third-party server — local grammar checking eliminates exposure. The accuracy is sufficient for standard grammar checking; Grammarly's cloud model is more capable for edge cases.
Voice capture for drafting
Voice Notes and Audio Recorder — speak first, write later. When you have a thought during research, record it as audio. It downloads as an MP3 to your machine.
Useful for: narrative outlines, scene ideas, section arguments. Many writers find that speaking an idea is faster than typing a note, and the audio can be referenced while drafting.
Research tab management
Tab Manager and Session Saver — save named sets of research tabs for each piece you are working on.
A long-form article or book chapter might require 20-30 reference tabs. Tab Manager lets you save this context as a named session ("Chapter 3 sources," "Interview background") and restore it in one click. Close the research context when you switch to drafting; reopen it when you need to cite sources.
Daily writing tasks
Daily Planner and To-Do List — today's writing goals on every new tab. "Draft section 2," "Edit introduction," "Research claim X." The new tab visibility means your writing goals are always in front of you.
Habit building for consistent output
Habit Tracker — a monthly grid for tracking writing habits. "Write 500 words," "Edit for 1 hour," "Read for research." Daily check-in on the new tab makes the streak visible.
Dark mode for extended sessions
NightOwl — if you write in the evening, automatic dark mode that follows sunset eliminates the need to manually adjust the display.
