Firefox puts privacy first but sacrifices extension support and can break sites, while Shift just wraps account switching around Chromium and feels like a thin layer on top of Chrome.

Only use Firefox if privacy is your top concern; stick with Shift if you just want easy account switching inside a familiar Chromium setup.

If you care about browser extension support and website compatibility, Shift has a clear edge over Firefox. Shift runs on Chromium, so most Chrome extensions work and websites are far less likely to break or act weird. Firefox, on the other hand, uses its own Quantum engine, which means way fewer extensions and a higher chance of sites not displaying right, especially with niche banking or newer tech.

If you're someone who relies on a big ecosystem of extensions or just wants things to work without hiccups, Shift is the safer pick. Firefox is only worth considering if privacy is your absolute top priority and you're willing to juggle a second browser for everything else. For most people, extension support and compatibility matter more day-to-day, and Firefox just falls short there.

Firefox Editor's Verdict

User Experience

Firefox sets itself apart with a privacy-focused approach, but you immediately run into friction from its limited extension support and lower compatibility with websites. You lose access to the huge ecosystem of Chrome extensions, unless developers specifically rebuild them for Firefox, which rarely happens. That means you're stuck with fewer options, and there's a real chance that some sites simply won't work right.

If you pick Firefox as your main browser, you'll probably find yourself reaching for a second browser just to get full features or to use sites that don't play nice. The interface doesn't get in your way, but the constant need to switch browsers or deal with missing tools breaks any sense of a truly efficient or seamless workflow. You can get by, but it never feels smooth or fully reliable for heavy or demanding use.

Shift Browser Editor's Verdict

What is Shift?

Shift is a tool that I've tried incredibly hard to like over the past 7+ years. The day I first found it, I was so stoked with it, until learning that it didn't have all of the Chromium extension support.

They've since made major strides on that front and have most extensions now supported, but it's beginning to feel a bit like a relic from the past, and pales in comparison to that of the more recent entrants into the space like Arc Browser and SigmaOS. In-fact, comparing Shift alongside Sidekick Browser and you'll be sure to confuse them with one another.

Who is Shift For?

I just have a tough time recommending them at this point, they really just allow for your favorite apps to be pinned on the sidebar and easy account switching with some quick action features.

They'd like to focus on the productivity users, but we feel like you can get most of the positives of Shift in your existing browser by utilizing a tool like Workona or Toby.

Who Shouldn't Use Shift?

If you're unwilling to install a new browser, stopping to use your beloved Chrome, Safari, or Firefox, well, you'd be hard-pressed to even give this browser a shot. We just don't feel like it innovates enough to actually take over your primary browser replacement, especially when looking at Shift vs Arc Browser for example.
