Reading the blogs of Mozilla contributors is a great way to keep up with the latest news about Mozilla. (Reading mozillaZine is required.) To save you time, Henrik Gemal has put together a page of Mozilla Related Blogs aka Blogupdates that shows a snippet from the latest few posts from each blog. Even better, each time you visit the page it marks which blogs have been updated since your last visit. Many thanks for the page!
To save a few more seconds, I created a bookmarklet that will open a new window for each blog that has been updated. Go to his Blogupdates page and click the bookmarklet. I wish there was a way to get them to open in new tabs — opening lots of windows can be slow — but that doesn’t seem to be possible from a bookmarklet. (I’ve heard that there’s an extension (multizilla?) that might support this but haven’t checked. Perhaps there’s one that lets you force opening of new windows to use tabs.) The bookmarklet also leverages code and specifics of his site, so it may break if he makes any changes.
I’ve found that a quick way to switch between them on Windows is to use Alt+Tab immediately after they finish opening. If you close each blog window after you read it and then press Alt+Tab, you’ll jump to the next one. This also lets you read them oldest to newest.
Update: Well that didn’t last long. I fixed it to work with the site again after some style changes caused it to break.
