Problem
Some users in certain locales (like Austria) had trouble entering target sample rates in Firefox. The problem happens because toLocaleString() formats numbers using local rules (like "1.000,25" instead of "1000.25"), but parsePercent() uses parseFloat(), which can’t handle these local number formats.
Solution
Replaced
.toLocaleString()with.toString()inorganizationSampling.tsxwhen setting up the form. This keeps the number format consistent so it can be parsed correctly and matches how the rest of the project handles sampling numbers.closes https://linear.app/getsentry/issue/TET-1001/localization-issue-with-number-formatting-in-firefox-affecting-ds
