## Description

Improves readability of Jira ticket diffs.

Jira Diff Highlighter is a browser extension for Chrome, Edge, and Firefox that enhances the readability of Jira issue description diffs. It transforms standard Jira diffs into a more user-friendly, side-by-side comparison with highlighted changes.

Key Features:
- Enhanced Diff View: Transforms standard Jira diffs into a readable side-by-side comparison.
- Highlighted Changes: Clearly see additions, deletions, and modifications with color-coded highlights.
- Configurable Large Change Handling: Choose the character limit for collapsing large insertions or deletions, keeping long Jira updates readable without cluttering the page.
- Show Full Text: Expand any collapsed large change inline when you need to inspect the full insertion or deletion.
- Toggle On/Off: Switch between enhanced and original diff views from the extension popup.
- Multi-Tab Support: Maintains consistent state across multiple Jira tabs.
- Custom Jira Domains: Atlassian-hosted Jira works automatically, and custom Jira domains can be enabled with explicit per-site access.

Perfect for:
- Developers reviewing code changes
- Project managers tracking requirement updates
- QA testers following bug report modifications
- Anyone who frequently works with Jira issue descriptions

Jira Diff Highlighter works automatically on Atlassian-hosted Jira instances using <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/84fedc0906f0923f3bcb7a0a76a2a1672b507c8e9ceb18c97c0b779a3951b244/http%3A//atlassian.net" rel="nofollow">atlassian.net</a> subdomains. If your team uses Jira on a custom domain, you can add that domain from the extension popup and grant access only to that site.

Open Source

Jira Diff Highlighter is an open-source project. You can view the source code, contribute, or report issues on GitHub:
