LeetBlur: Blur & Redo LeetCode Solutions

Want to hide your previous LeetCode solution so you can redo a problem you've already solved? When you reopen a solved problem, LeetCode auto-restores your old submitted code, which spoils the whole point of practicing again. LeetBlur fixes that. It blurs your previously saved solution behind a frosted overlay the moment the problem loads, and adds two small buttons to the code pane: - Look: reveal your old solution when you're ready to check it. It stays revealed until you open a different problem. - Clear: wipe your old code and reset the editor to LeetCode's starter stub for the current language, so you can redo the problem from a clean slate. The blur only appears when there's an actual solution to hide. A brand-new, template-only editor is left alone, so a fresh problem is never touched. Prefer not to see difficulty labels? Turn on Hide difficulty and LeetBlur hides the Easy, Medium, and Hard tags across LeetCode, on both the problem list and the problem page, so an intimidating "Hard" doesn't psych you out before you start. It's off by default; flip it on any time from the toolbar. You're always in control. Flip blurring or hide-difficulty on or off from the toolbar popup, or from the on-page control button that sits quietly in the corner of every LeetCode page, so your settings are one click away without ever leaving the problem. Your choices are remembered across pages and sessions. Private by design: everything runs locally in your browser. No account, no tracking, no analytics, and no data ever sent to us (we have no servers). The only network request goes to LeetCode's own public API, without your cookies, to fetch the problem's starter template. If you've been looking for a way to hide or cover your previous LeetCode answers so you can practice already-solved problems from scratch, that's exactly what LeetBlur does. Works on https://leetcode.com (blur on problem pages; hide difficulty across the site).
