Bugsnag can automatically notify you of unhandled exceptions in all versions of all browsers (yes, even IE 6!). Some browsers let us do even more, and internally we have 3 tiers of higher quality support:
|Tier A||Tier B||Tier C||Supported|
Most users are on tier A or B browsers (91.2%), errors from these browsers are deduplicated most effectively, and there’s lots of debugging information available.
A number of people are still on tier C (5.2%) or worse (3.6%) browsers (though those proportions will diminish over time). We can still notify you of problems in these browsers, though the quality is significantly lower.
If you’re only targetting up-to-date users, you can tell Bugsnag to only report errors from modern browsers by going to “Settings -> Error Handling”
