    Like it or hate it, Edge has evolved into a worthy rival for all at the top of the Blink-based web browser heap, and for those that have to operate on Microsoft environments with multiple sets of Microsoft credentials, its intuitive maintenance and switching of profiles to suit the task underway is an absolute game changer. It's become more tightly integrated with Outlook and has begun feeling like a co-equal member of the Office suite constituents.

    Imagine Chromium but with bing by default for search and with not spyware of Google, instead of Microsoft's one. Not Open Source, no good add-ons, no privacy, no security and a company that only want your data for sell it...

    Bloatware. Spyware. So ingrained into registry that you have to use win11debloat in order to uninstall. Firefox, its only a few clicks to remove or get.

    Despite Chromium being "open source", it still downloads Google-related crap and phones home to Google. If you value your online privacy, you'll appreciate the Ungoogled Chromium browser, which removes all that. However, Firefox remains more customizable in terms of privacy options.

    More like GNU/Chromium. It will not load anything deemed "non-free". This includes DRM content, regular Chrome extensions, and a bunch of other random tweaks here and there. Not a good idea to use unless you know what you're doing.

    1. It doesn't update like Chromium 2. It's hard to install on Windows and Linux 3. There is no DRM support, so forget about watching Netflix on it 4. It's hard to install extensions, no access to Google Web Store. 5. No Widevine codec available and to install it is hard and need manual intervention that doesn't work always.

    It's easy to use and customize. It's clean, the preferences are easy to understand. They could do a little better on the support side, but everything else is awesome.

    Falkon's really fast even on low-end hardware. Add-ons are still really sparse though, and I haven't found a good way to sync bookmarks or connect it to KeePassXC yet.

    It isn't really bad, but not a lot of add-ons and based con Qtweb (chromium). Not fingerprinting protection like Firefox but also no telemetry by default. It is ok, but it could be better.
