Extensions are nothing new, but lately it seems like they’ve been becoming a lot more useful. These are a couple I’ve found that you might find useful as well.
Bookmarks Sync – Simply uploads your bookmarks to your website when you quit Firefox and downloads them when you start. I use it to keep my work/home comptuers synced.
Bookmarks Backup – With all this syncing going on, I want to make sure I have a backup of my bookmarks in case something goes horribly wrong. This is the tool for the job.
Highlight Search – Click a word, right click and select “highlight word” and poof, all the instances of that word are now yellow and red! Works like a charm.
