Nice Firefox extension to check both dead and duplicate bookmarks. Still in experimental but I haven’t had any problems with it (except it being slow, I have huge amount of bookmarks.)
Ever wonder what my Firefox addons are? Now you know! (I didn’t bother adding ones that come with programs, e.g. the AVG thingy, or some Microsoft .NET framework assistant.)
AdBlock Plus: Does what it says — blocks ads. And saves bandwidth too.
BookmarkDD: Finds duplicate bookmarks, also deletes them. Good for disorganized bookmarker like me.
ColorfulTabs: Just makes the tabs colorful. Nice to look at, and it can be easier to tell apart tabs.
FEBE: As well as MozBackup, I use this to backup my extensions and stuff.
FoxClocks: If you have a lot of friends in different timezones, this is for you.
IE Tab: Good for when stupid site developers make their sites incompatible with Firefox.
ImageShack Toolbar: I use Imageshack a lot. Need I say more?
Menu Editor: Good for when other addons add stuff to the context menu you’ll never use.
Stop Autoplay: Stops….autoplay. Well, duh.
Here are a few options, for when you want non-social (anti-social sounded awful) bookmarks.
Foxmarks: Actually a Firefox addon for syncing bookmarks, it lets you access and edit your bookmarks online.
Google Bookmarks: Probably one of the better-known ones. I used to use it before switching to Foxmarks.
MyBookmarks: Although I haven’t tested this, it seems like a good option. (However, at the moment, new signups are disabled.)
Also, although it’s not online, here are a few options for USB drive users:
When doing the math for timezones, I’m pretty good, but I get confused when one timezone is in AM and the other in PM.
However, I discovered an addon, FoxClocks, which can display whichever timezones you want! You can even set it to sync with a LAN server — if you’re using Firefox offline, for instance.
When I first got Firefox, the first thing I looked for was a way to make my tabs colored. And I found ColorfulTabs. Also, it lets you choose certain colours for certain domains — so for example, you can make all pages on mozilla.com orange, or sourceforge.net purple.
In these days, banner ads can be a security threat! They can redirect you to pages which automatically download spyware onto your computer.
Fortunately, Firefox blocks automatic downloads. But those banner ads can still be annoying. Firefox blocks pop-ups, but not banner ads. That’s where AdBlock Plus comes in.
You can either “teach” it to block ads, or save your time and use a predefined list.
If you’re like me, you hate it when music or videos start playing — LOUD — when you load a webpage.
If you have Firefox, you can use Stop Autoplay to block it. (You can still play if you choose to — simply click on the frame.)
Also, you can choose to block all flash, which is useful if you hate those flash banner ads and don’t have an adblocker installed.
