I recently installed new firefox version on my ubuntu and was trying to find some text on a webpage. Suddenly, as I pressed next to search it, the searchbox turns red showing Phrase not found and started making beep noise. I was annoyed, So was thinking of way to disable / turn it off. To look for some preference to set, I typed about:config (special firefox about: pages) in location bar and searched for sound. I was lucky i found two related preferences.
So you can set accessibility.typeaheadfind.enablesound Value to false by double clicking it. And you are done. No more beep beep to annoy you.
With Firefox 3, you can use firefox browser to view contents of zip/jar files.
For viewing contents of filename.zip type following at location bar:
jar:file://< full path to filename.zip >!/
This is specially very useful when you want to see contents (.js, .css, .html files) included in firefox extension’s jar file. After it list the contents, you can easily browse through the directory, sorting files etc.
Update: Security problems that come with jar: protocol
While serching for pages related to jar protocol in firefox, I found an interesting article at www.gnucitizen.org
In simple terms, it means that any application which allows upload of JAR/ZIP files is potentially vulnerable to a persistent Cross-site Scripting. Potential targets for this attack include applications such as web mail clients, collaboration systems, document sharing systems, almost everything that smells like Web2.0, etc, etc, etc.
Similar security concerns also arise in data: protocol in firefox. So one need to be careful to filter files you want to allow for upload. Actually, once I had similar situation with a website which allowed you to host image files, but the problem was they were not checking for file types. Thats means you are allowed to upload a php file too. So now you can do anything you want with that server (don’t ask me what I did ). So beware of such issues.
Firefox provides us with a special page, about:crashes (type it in location bar) to track all the crash reports that you have submitted whenever firefox crashes. Firefox crashes are being handled by Mozilla Crash reporter tool, BreakPad.You can also serach
Advantage of submitting the crash report is that if its a widely occurring bug then it will appear on Mozilla: Top Crashers, and chances are that it will get resolved in next release.
Read more about firefox crashes at MozillaZine. Also Standard diagnostic steps to take when firefox hangs or crashes.
I was going through bits of firefox code, and I found the algorithm used by firefox to measure password strength. You can find it in function setPasswordStrength() in this file : chrome://mozapps/content/preferences/changemp.js.
So point schema for password strength:
For length : password-length*10 – 20 (Max 30)
For Numbers: no-of-numerics * 10 (Max 30)
For Symbols: no-of-symbols * 15 (Max 45)
For UpperCase: no-of-Uppercase * 10 (Max 30)
Your password strength is sum of all these points. So smallest password that would get 100 on password meter can be : AAA@@@ or something similar. But there should also be some criterion for the uniqueness of the characters.
Interesting read-on how to choose good passwords. that are also easy to remember. Please share your tips on choosing passwords [but yeah dont share passwords ]
Type resource: in your location bar to directly go to firefox installation directory.
You may have read about firefox’s special about: pages like about:config, about:cache etc. Or you can go through Firefox about: pages to have an idea about them. There is one similar functionality in firefox which allows you to view page source of a page. You can type
this in location bar to view page source of google.com.
So i have made this Bookmarklet to view page source: View Source (So you can drag this to your bookmark toolbar to have quick access).
Key Board Shortcut: Use Ctrl+U to view page source
Yesterday I was working late night till 3AM, to update my extension ‘My Del.icio.us Toolbar’ which I made long back in October 2006. Reason was to make it work for newer versions of firefox. But then I added some new features too :
- I added a Explore feature which is similar to Stumble.
nsICookieManagerinterface to iterate over all of the cookies.
Try My Del.icio.us 2.0 (Right now you may have to login to access the extension as it’s in Sandbox.)
I also noticed that mozilla has redesigned the extension page. They have also added a nice statistics Dashboard for extension, provided graphical representation of number of downloads, active daily users etc. I was surprised to see that older version of My Del.icio.us has reached a total download of 11,200 (not that a big number but still surprising for me) and number of active user around 1000.
Try My Del.icio.us 2.0 and provide feedback.
Also Try: Del.icio.us SearchER
