Browser URL Size Limits Investigation
— Major browser engines demonstrate significant differences in how they enforce URL length limits.

Firefox relies on user-configurable preferences, employing a 1 MB "standard" limit but permitting up to 512 MB in absolute terms, with stricter limits (2,000 characters) for history and bookmarks.
