addons for Firefox

Okay, just a quick post. I've been using quite a few Firefox add-ons, and there are some I consider very useful.

These are my recommended add-ons (in alphabetical order):

• AdBlock Plus - most of the time, I don't even notice this add-on. But I have to admit, the only reason why I didn't notice was that I didn't see any ads. I consider AdBlock to be a very useful extension, and the best thing is that you probably won't notice it.
• Firebug - the most useful tool for analyzing webpages for any web developer. (If you aren't a web developer, then it may not be useful to you.) In general, you would rather look at the neatly generated HTML code in Firebug than to look at the HTML page source itself (which is usually messy), and it also provides tools to view the CSS style of each element. You can even dynamically change the webpage you are viewing with Firebug!
• Foxmarks Bookmark Synchronizer - if you use bookmarks on various computers or OS's, then you might want this so that you can synchronizes your bookmarks across computers. Most of the time, it works pretty well at synchronizing, but from my experience, it is not a "perfect" solution (there are some weird "glitches" occasionally, especially if you don't know what you are doing). Still, it's really useful and definitely worth using.
  
• FoxyProxy - this is really useful if you surf using proxies. If you use Tor often, and want Firefox to use Tor only when necessary, this can be a time-saver indeed. Once it knows your basic filters, it will automatically use the Tor proxy when you need it. If you want to turn it on temporarily, you can just click the icon on the right of the status bar. It certainly saves a lot of time. (If you don't use proxies, then this is not applicable to you.)
  
• IE Tabs - this is my favorite way of viewing pages the require Internet Explorer. Instead of view IE in its own window, you just click and it creates a tab within Firefox that emulates IE. Again, a time-saver, and you don't even have to run Internet Explorer.

Note: This is not an ad of any kind (although my tone was a bit like that); I'm just suggesting add-ons that I personally consider useful.
