The new Firefox design is here

Original Article ↗ Hacker News Discussion ↗

Mozilla’s latest Firefox redesign—featuring pill-shaped tabs, gradients, a new sidebar, and native vertical tabs—has triggered a polarized response. Some users praise the fresher look, better vertical tab experience, and alignment with modern OS themes, while many others condemn the rounded “pills,” increased whitespace, and frequent aesthetic overhauls, arguing they hurt usability for tab-heavy workflows and distract from performance, stability, and feature work like ad blocking or advanced tab management. Several comments focus on workarounds (themes, config flags, userChrome.css) and express broader frustration that UI churn continues while Firefox’s market share and ecosystem challenges persist.

Overall reaction to the redesign

  • Very mixed response, skewing negative in this thread.
  • Some like the new look, calling it polished, more aligned with modern macOS/GNOME styles, and appreciating that an open-source project invests in design.
  • Many others see it as unnecessary “redesign for redesign’s sake” that breaks a previously “fine” UI and feels infantilizing or overly playful.

Tabs, pills, gradients, and spacing

  • Strong backlash against pill-shaped tabs, heavy rounding, gradients, and increased padding/whitespace.
  • Tab hoarders argue the new horizontal tab layout wastes vertical space and reduces information density; they want compact, rectangular tabs that reach the screen edge.
  • Some praise vertical tabs and split view, citing better organization and context management; others insist such features belong in extensions, not core.

Customization and workarounds

  • Multiple mentions of mitigations:
    • Settings → Appearance → Window Density → Compact.
    • Disabling sidebar, switching themes (e.g., Dark, Ash).
    • about:config → browser.nova.enabled → false to partially revert.
    • UserChrome.css tweaks for square tabs, removing gradients, hiding mascot, etc.
    • Third-party projects like Firefox-UI-Fix and extensions like Sidebery.

Desire for features and performance over visuals

  • Many wish Mozilla would prioritize:
    • Stronger built-in ad/tracker blocking.
    • Better tab/session/bookmark/history management.
    • Improved memory/CPU performance, especially with many tabs.
    • Sync reliability, dark mode controls, site CSS/JS management.
  • Some note specific missing integrations (e.g., virtual card support) that push them to Chromium browsers.

Performance and compatibility concerns

  • Reports of Firefox spawning many processes and becoming unusable on ad-heavy pages.
  • Some users experience a high rate of form breakage on smaller sites; others report near-zero issues and suspect extensions.

Mozilla strategy, funding, and trust

  • Frustration that frequent visual overhauls don’t reverse market-share decline.
  • Recurrent suspicion around Mozilla’s dependence on Google and limited appetite for aggressive built-in adblocking.
  • Meta-discussion about the disproportionate hostility Firefox-related announcements attract, versus a quieter base of satisfied users.
