## Description

Containerise is a powerful Firefox extension that automatically opens websites in dedicated containers. By simply adding rules that map domains or subdomains to containers using an easy CSV-based configuration, users can ensure consistent web compartmentalization, enhancing privacy and management.

Users can define mappings using basic domains, glob patterns, or regex to tailor the opening behavior for all matching sites. For example, mapping `amazon.co.uk` to a "Shopping" container ensures all Amazon UK visits open isolated from other browsing activities. This functionality is disabled in private mode, respecting user privacy preferences. Containerise streamlines container setup, making multi-container browsing effortless and efficient.

## Review summary

Users praise Containerise for reliable performance and as a strong replacement for Multi-Account Containers, with powerful URL/path-based rules and good handling of subdomains. It fits well with privacy workflows and bookmarks. However, maintenance appears inactive, cross-device syncing is missing, and users report bugs and occasional data loss. Regex/documentation are limited, and there are compatibility issues with Firefox updates. Overall, it’s valuable but has notable stability and synchronization drawbacks.

### Pros

- Reliable and generally smooth performance; widely considered to work well.
- Strong replacement for the Firefox Multi-Account Containers extension; improve workflow.
- Powerful rule-based URL/relative-path matching to assign sites to specific containers.
- Effective handling of subdomains and multiple accounts with per-site rules.
- Easy to use and integrates well with privacy workflows, including bookmark support.

### Cons

- Not actively maintained; development appears inactive.
- Lacks cross-device sync for container/URL rules; manual setup on each install.
- Buggy/unstable behavior reported (UI issues, tab loops, occasional data loss).
- Regex support is limited (no flags, limited examples) and documentation is sparse.
- Compatibility issues/regressions with Firefox updates causing features to stop working.
