I'm frustrated by how unreliable Instagram's web client has become. I use Firefox and plan to keep using it, so some compatibility issues may be browser-specific, but basic features often fail: buttons do nothing, pages require a full refresh, and certain views refuse to load. Even the video carousel behaves strangely, sometimes continuing playback from the previous video instead of restarting at the beginning.
Other large platforms have similar problems, including awkward nested-comment navigation and scroll positions that reset unexpectedly. It makes me wonder whether major companies have largely stopped investing in polished web experiences because most users now rely on mobile apps. Is the web version intentionally kept basic, or are apps simply a higher priority?

Firefox’s smaller market share definitely affects priority. A company may decide that fixing a Firefox-only bug is less valuable than shipping features for the majority of users. That said, basic navigation and playback problems are still poor quality control, especially when the same sort of issues appear across multiple devices.
Instagram has a particularly poor reputation for cross-platform consistency, and the mobile app isn’t flawless either. Broken comments, links, and loading screens show that the issue may be less about deliberately sabotaging the website and more about a company that prioritizes growth and engagement features over maintenance and polish.
This isn’t universal. Companies whose products are primarily web-based still have a reason to maintain excellent browser experiences. The pattern is especially noticeable with social media and advertising businesses, where the app gives them more direct access to notifications, permissions, and user behavior.
There are also technical reasons. Browsers run inside stricter permission and security boundaries, while native apps can integrate more deeply with the operating system. Supporting every browser and debugging edge cases takes time, so companies often prioritize the platforms used by most of their audience—usually mobile apps and Chromium-based browsers.
For many social and ad-driven companies, the web version is mainly a funnel toward the app. Native apps usually produce more engagement, more notifications, and more opportunities to collect behavioral and device data. That gives companies a strong incentive to make the app the best experience while keeping the website functional enough to avoid completely losing web users.

The market-share argument is understandable, but relying almost entirely on one browser engine is risky. A healthy web needs independent engines to remain viable, otherwise compatibility problems and platform control become much harder to challenge.
