About this extension
Tired of clicking "Join" one subreddit at a time? Subreddits Auto Joiner lets you bulk-join dozens — or hundreds — of subreddits in a single session, with smart randomized delays that keep your account safe.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🚀 HOW IT WORKS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. Paste a list of subreddits into the popup — one per line
2. Pick your speed (Slow, Normal, or Fast)
3. Hit "Start Joining" and let the extension do the rest

It opens each subreddit in a worker tab, clicks the Join button, waits a randomized delay, then moves to the next one. That's it.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

✨ KEY FEATURES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

▸ Bulk Join — Process 10, 50, or 500+ subreddits in one go.

▸ Anti-Detection Delays — Three speed presets with randomized intervals:
🐢 Slow (7–14s) ⚡ Normal (4–8s) 🚀 Fast (2–4.5s)

▸ Extract from Page — Browse any Reddit page (lists, wikis, recommendations) and pull every subreddit link with one click. No manual copying.

▸ Pause / Resume / Stop — Full control at any time. Pause the queue, grab a coffee, come back and resume exactly where you left off.

▸ Session Recovery — Closed the popup or browser mid-job? The extension remembers your progress. Reopen it and hit "Continue Remaining" to pick up right where you stopped.

▸ Retry Failed — If some subreddits failed (404s, network issues), hit "Retry Failed" to re-queue only the ones that didn't work.

▸ Live Progress — Real-time progress bar, percentage counter, and a color-coded activity log showing the result for every subreddit (JOINED / MEMBER / 404 / PRIVATE / ERROR).

▸ Completion Stats — When a job finishes you get a clean summary: total joined, already a member, and failed — at a glance.

▸ Job History — Past sessions are saved (up to 50). Expand any history entry to see its full results, retry its failures, or continue its remaining items.

▸ Floating Widget — A non-intrusive floating progress widget appears on Reddit tabs while a job is running, so you can browse while it works.

▸ Flexible Input — Accepts every format:
r/AskReddit, /r/funny, https://reddit.com/r/pics, or just "pics"
