How to Uninstall Microsoft Windows Presentation Foundation (WPF) Firefox plugin

mozilla firefox wpf

Firefox is relatively secure and well designed web browser. Any closed source plugin and especialy the Windows Presentation Foundation Plugin from Microsoft can be serious security hole. There is also posibility of your privacy violation. Who knows what the Windows Presentation Foundation Plugin from Microsoft exactly do and what data it reads, colect and process ? Generall security rulle is not to use any software with closed source, becouse it cannot be verified therefore it cannot be trusted.

via Uninstall Windows Presentation Foundation Plugin From Firefox

Okay so I got a pop-up from Firefox saying it is blocking Windows Presentation Foundation as it’s unsafe. In the same light as the .Net Assistant, the WPF can not be uninstalled with a GUI. Firefox blocks it now and if you want to remove it, follow the link above. I think it probably piggy-backed on the slew of security updates released a few days back.

CyberSearch Firefox Extension

[CyberSearch :: Add-ons for Firefox]

Despite it’s dubious sounding name, I feel CyberSearch will soon become an extension I can’t live without. If you have been using Keyword searching on Firefox, you’d fall in love with CyberSearch. This cool extension basically displays search result in your Awesome Bar (stupid name isn’t it?) as you type. This saves you that extra trip to the search results page. What’s cool is you can set up keywords to limit your search to certain sites, essentially making the previous keyword searching method obsolete.

I set up imdb to limit my search to IMDB and this is the result:


Definitely a time saver, if you search for things extensively. It is also integrated with other Google services.

Another Firefox Performance Tip

[Lifehacker: Make Firefox Faster by Vacuuming Your Database]

Firefox tip: Firefox 3.0’s Awesome Bar added all kinds of features to the ‘fox, but unfortunately it’s also created some performance issues—for example, by upping the default history time, leading to larger, fragmented databases. This quick hack speeds things up.

There’s an experimental plugin released which automates this ‘vacuuming’ task. You get to set the number of restarts before the plugin automatically sorts out your database or you can set it to reveal the status bar icon after a certain interval if you derive some kind of satisfaction from clicking a simple button to make your browser faster.

I make sure of the awesome bar rather often for searching or hoping I’m lucky and get to the site I want. Hopefully this will make somewhat of a difference. You can follow Lifehacker’s article and discussion on the plugin here.

Lifehacker: How to Fix Annoying YouTube Jumpiness in Firefox

[How to Fix Annoying YouTube Jumpiness in Firefox – Firefox – Lifehacker]

Many users, myself included, visit YouTube on an almost daily basis. Ever since Firefox version 2.0 implemented the session restore function, when you are watching a video on YouTube (perhaps on other video sites as well, I haven’t really tested that), you may notice a tiny freeze-up of the video every 10 seconds or so. This happens because the session restore is by default set to save all open tabs every 10 seconds. This is especially noticeable if you happen to have a lot of tabs open at once.

The quick fix for this problem, at least for my own sake, is to increase the time between each of the saves performed by session restore. By opening about:config in your Firefox address bar, then typing browser.sessionstore.interval in the filter box, you’ll see a value of 10000, which is in milliseconds. (Meaning your session is saved every 10 seconds.) I changed this to 300000, or every 5 minutes, as I don’t have the urgent need for tab restoration. If you feel like being more on the safe side, try increasing it to something a bit lower, say 120000, or every 2 minutes.

I’ve been having the problem myself. I tested the sessionstore and it seems your tabs are stored whenever you close down your browser properly anyway so a 5 min tab storing for when your browser crash should not be that much of a biggie.

Now to test if YouTube indeed becomes less jumpy.

Firefox 3.5 and 7 extensions I can’t live without

Mozilla Firefox

In case you haven’t upgraded your Firefox to the latest 3.5, hit your Check for Updates… button. If you don’t have Firefox (*gasp*) grab it now!

Some of the features includes:

  • Faster page load
  • Faster Javascript
  • Smaller memory footprint
  • Tabs tearing
  • Built-in privacy browsing
  • And more…

This is also a good opportunity for me to share some of the extensions I use, 7 of my favourites which I may or may not live without:

Adblock Plus + NoScript


Ever been annoyed by all those ads and banners on the internet that often take longer to download than everything else on the page? Install Adblock Plus now and get rid of them.

Adblock Plus


The best security you can get in a web browser!
Allow active content to run only from sites you trust, and protect yourself against XSS and Clickjacking attacks.


With these two extensions, you basically idiot-proof your system against most threats. And it’d get rid of all the annoying ads, pop-up or otherwise.



The first and only download manager/accelerator built inside Firefox!


The description is rather brief but dTa! is a must-get in my opinion. It has other nifty stuff like resume, queuing and mass grabbing of embedded static media and links.



A customizable mouse gestures extension which enables you to execute various commands and user scripts with five types of gestures.


I used to use another extension but it became incompatible with 3.5. I run gestures without trace and only have short-cuts for Next / Previous Tab, New Tab, Reload, Reload without cache and Close Tab.

Greasemonkey + Greasefire


Allows you to customize the way a webpage displays using small bits of JavaScript. …


Basically allows you to customise how parts of websites look with bits of Javascript; basically client-side changes to website. Of course, not all of us know what we’re doing, that’s why there’s a huge library of scripts available at UserScripts.


Automatically find Greasemonkey scripts on (requires Greasemonkey)


Rather self-explanatory. Good helper to Greasemonkey and entirely pointless without it.

Some of the Greasemonkey scripts I’m running:




IE Tab – an extension from Taiwan, features: Embedding Internet Explorer in tabs of Mozilla/Firefox…

IE Tab

There’s basically 2 function of this extension. The first is as the author intend, “easily see how your web page displayed in IE”. The second, which I mostly use it for, is to make a web page look sensible to me because there are still some sites which Firefox can’t render properly.

Tabs Open Relative


Tabs Open Relative makes all new tabs open to the right of the current tab, rather than at the far right of the tab bar (optionally this only applies to links).

Tabs Open Relative

New tabs in Firefox are typically chucked at the end of tabs list. This extension simply makes new tabs open in a new queue relative to current tab. If words are hard to comprehend, the author has a simple example:

In the case where several new tabs are opened in a row without switching tabs, each subsequent tab will be opened to the right of the previous one, so as to keep them in order.
For example if you have three tabs open, {A}, {B} and {C}, where the current tab is {B}, and then you open three more tabs, {1}, {2} and {3}, you’ll get:
{A} {B} {1} {2} {3} {C}.



UnPlug is an extension which lets you save video and audio which is embedded on a webpage – it’s a video download tool.


This is the only extension in this list that isn’t compatible with 3.5 but seems to work perfectly. Somehow the author doesn’t update at Mozilla’s add-on portal anymore so go to the author’s website to grab the latest version.

Some of the cool features:

  • Don’t need to buffer the video
  • Doesn’t send you to another URL to download the video
  • Tries to locate highest quality video, meaning it’d help you get a HD MP4 video file if it’s available
  • Integrates with dTa for higher speed!

Follow the instructions provided here at Lifehacker to circumvent version checking for extensions to use UnPlug. It has a huge USE AT YOUR OWN RISK warning but UnPlug hasn’t exploded on it yet.

Of course I cheated and listed 9 extensions instead of 7 but who cares. Hope this rare non-vlog entry is useful. Do leave a comment if you have any cool extensions to recommend or feedback for any of those in the list.

Fix for WordPress Image Uploader crashing Firefox

[WordPress Image Uploader crashes Firefox, how to fix it]

Just like Ram, it only occurred for the first time for me. I tried removing all the sites from my Gears settings but that didn’t solve the problem. Disabling Gears from Firefox’s add-on list worked as reported.

This is very odd as there’s no particular update from either Google Gears or WordPress or Firefox, hope there’s a proper official fix soon.

How to remove Microsoft .NET Assistant from Firefox

Mozilla Firefox

Not exactly breaking news but better late than never. Prevent your favourite browser from becoming Internet Fire Explorer Fox.

2nd link has lots of screen shots and may be easier to follow.

This update adds to Firefox one of the most dangerous vulnerabilities present in all versions of Internet Explorer: the ability for websites to easily and quietly install software on your PC. Since this design flaw is one of the reasons you may’ve originally chosen to abandon IE in favor of a safer browser like Firefox, you may wish to remove this extension with all due haste.

I like Microsoft products overall, but I cannot and will never condone blatant misuse of corporate power to distribute useless, unasked-for software to masses who do not have the skills to tell part good from bad or how to handle issues like the above.

The Assistant, if at all, should be an optional package, with clear user consent granted before any installation. Furthermore, the installation should be fully 100% revocable, so that anyone using the computer can do it, via the standard Add/Remove panel.

This is a very serious breach of user trust. Not only is this package delivered without explicit approval, it’s also made difficult to remove. Moreover, its use is not clear. Lastly, the change affects third-party software, not one of Microsoft products, so the question is, what the hell did Microsoft want to achieve with this nebulous, spyware-like update? Animosity from a few trusted users? Force people not to install updates or use older versions of their products?

IE is bad for you, it’s true.

[Internet Explorer: Security Experts Advising You Stay Off Internet Explorer For Now.]

I don’t like using Internet Explorer for so many reasons. For a big corporation like Microsoft, they’re not particularly bothered with making their browser compliant with web-standards or even secure. So yea, if you’re still using IE, now is good time to jump on to another browser. I like Firefox. ;)
