Firefox , Flash player 11.3 & protected mode (Issues)

2 Comments »

 

Recently (June 6, 2012) Adobe introduced its new Flash player version 11.3 which supports protected mode for advance protection and allow flash plugin to run outside browser process and create separate sand-boxed version of flash plugin with low integrity process that will surely increase protection from bugs/flaws in Flash players discovered in the recent past. But now Flash plugin is directly accessing Internet instead of asking its parent process, like in the past, Firefox/IE or other browsers were responsible for communicating with the internet, but this new upgraded version of plugin needs direct internet communication (which is bad in my opinion, as now we needs to track its outgoing/incoming connection separately, no matter it is running with low/little access of system resources) Read the rest of this entry »

Microsoft launched a website today designed to give users a detailed look at how secure their browser is. The site, called Your Browser Matters, automatically detects the visitor's browser and returns a browser security score on a scale of four points.

When you visit the site, called Your Browser Matters, it allows you to see a score for the browser you’re using. Well, if you’re using IE, Chrome, or Firefox—other browsers are excluded. Not surprisingly, Microsoft’s latest release, Internet Explorer 9, gets a perfect 4 out of 4

Firefox 8 released

No Comments »

Mozilla announced today the official release of Firefox 8

The built-in search box in Firefox’s navigation toolbar has been extended to support Twitter searches. Users can now select Twitter from the drop-down list of available search engines. Mozilla partnered with Twitter earlier this year to release a special build of Firefox that ties into the social network. The search box integration from that custom build is now part of the official Firefox release.

Another noteworthy user-facing feature in Firefox 8 is stricter control over side-loaded add-ons. Mozilla is cracking down on third-party applications that install add-ons in Firefox without the user’s knowledge or permission.

If Firefox 8 detects side-loaded add-ons when it starts, it will disable them by default and display a prompt asking the user if they want the add-on to be enabled. This will help protect users from invasive toolbars and other unwanted cruft.

In addition to these new browser features, Firefox 8 also has some improvements under the hood. The browser’s HTML rendering engine has gained support for cross-origin resource sharing, a feature that will allow a website to load WebGL textures from other sites. WebSockets also got a boost in this release with an updated implementation that conforms with the latest draft specifications

Users can download Firefox 8 from Mozilla’s website. The new version will also be rolled out to users through the stable update channel.


Hacking Firefox and Thunderbird addons to work with new versions of Firefox/Thunderbird

No Comments »

Have you ever got used to a Firefox or Thunderbird addon that you really like, or just can't live without, and then a new version of either Firefox or Thunderbird is released, and suddenly your addon no longer works?

Of course, the generally recommended way is to search http://addon.mozilla.org for a new version, but sometimes when you try to update your addons, you find there is no new version, or it seems like nobody is maintaining the addon any more. I tend to live on the leading edge of new Firefox releases, I want the new features, I want the latest, and I want it now, so I quite frequently hit this problem. Fortunately, there is an easy way to keep using your favorite addons, usually with little or no risk.

The summary for those who just want to skim and jump in:

  • Download the addon file you want to update
  • Rename the addon archive file to add .zip to the end
  • Extract install.rdf
  • Edit install.rdf, find and change maxVersion, save the change
  • Pack install.rdf back into the install archive
  • Rename the file back to it's original .xpi name
  • Install using File, Open

The detail for those who need all the steps:
You will need only two free tools to help you do this job, the totally free 7-Zip or some other ZIP file management utility and hopefully knows how to use it. The other tool is a simple text editor. Microsoft's Notepad will do, but any other text editor will work if you have any particular preference. My preference is NotePad++ which is a good free programming and general purpose text editor.

A warning is the first important note here; always backup your Firefox or Thunderbird installation directory before doing any "hacking". While a problem is extremely rare, problems can happen, and you will only have yourself to blame if you don't take appropriate precautions before making any unsupported changes. I won't take any responsibility for any problems you inflict on yourself through sharing with you what I do on my own computer(s). It is often a good practice anyway to backup your installation directory before installing any new addon, just because you never really know what can happen, though usually by the time anything is approved and available for public download on http://addon.mozilla.org, it has been fairly well tested by others and proved to be safe. At the very least, before following my tips here, backup your profile and addons directories by making a copy of them to some other location on your disk. If you don't know how to do that, or don't know where your profile and other directories (folders) are, I don't suggest you try my tricks. Read Gizmo's article How to Back up Mozilla Firefox and Thunderbird, in which among other things Gizmo mentions using tools such as MozBackup which shields you for knowing how to do it manually.

Once you have taken your backup, the first step is to find and download the latest version of the addon you want, and download a copy to your disk. Remember, at this point you can not simply click the Install link, because you know the installer will tell you the addon is unsupported for your version of Firefox or Thunderbird, which is more than likely why you are reading this article! Normally, you would click the Install button, but in this case, you want to save the file to disk, so right click on the install (or Add to Firefox / Add to Thunderbird) button, and then click 'Save Link As'. Choose a location on your disk, make a new folder if necessary. The file you download will be named something like better_gmail_2-0.6-fx.xpi. On rare occasions you may find that when using Firefox, you just can't click 'Save Link As' for some reason. Try a different browser, you may have better luck saving the file when the browser itself is not capable of actually installing the addon.

Having saved the addon, you will need to extract one file named install.rdf from it, make a change, and then pack it back into the file. Since the addon is just a zip file containing all the supporting files necessary for the addon, the easiest way to extract files is to rename the original by changing the .xpi extension to .zip, or by simply adding .zip to the end of the file name temporarily. You will need to extract the install.rdf file from the zip file, edit it, and then put it back in again, so if you're not comfortable with these tasks without me describing them in great detail, don't try. Ask somebody else who is comfortable using zip to extract a file and pack it back in again to help you with this process.

Once you have the install.rdf file extracted, open it with your text editor, and look for lines like the ones listed below. Many addons don't have these lines, so they are not checking for specific versions, and you should not see any incompatibility messages.

    <em:targetApplication>
      <Description>
        <em:id>{ec8030f7-c20a-464f-9b0e-13a3a9e97384}</em:id>
        <em:minVersion>1.0</em:minVersion>
        <em:maxVersion>3.0</em:maxVersion>
      </Description>
    </em:targetApplication>

The part you need to change is the line with the maxVersion setting. As long as I am running Firefox 3.0.1, this addon should work for me, but when I upgrade to 3.1, or 4, it will no longer work. The next step is to change the maxVersion setting to at least the version you are currently running, I usually just change it to 9.0 which means I can run any version that will be released for some time to come.

    <em:targetApplication>
      <Description>
        <em:id>{ec8030f7-c20a-464f-9b0e-13a3a9e97384}</em:id>
        <em:minVersion>1.0</em:minVersion>
        <em:maxVersion>9.0</em:maxVersion>
      </Description>
    </em:targetApplication>

If your install.rdf looks really weird when you open it, and seems to have just a few lines that look really long, and don't all display on the screen, don't panic. Most likely, the addon programmer has used a Unix or Linux system to create the files, or they have used an editor that does not automatically wrap lines. The Unix or Linux option may be the more likely of the two, and if you don't know what I mean by line termination characters and vi, explaining more would only confuse you even more. Either way, some Windows text editors will know what to do with a non-typical Windows text file, Notepad will not, so if you see just a few long lines, just use Ctrl F, or click Edit, Find, and then type maxVersion. All you need is to find this setting, change it, and save it. Don't worry about the strange file formatting.

After making the change, save the install.rdf file, pack it back into the addon zip archive, and rename it back to it's original name ending in .xpi. The last step is to actually install it, and to do this, rather than browsing to http://addon.mozilla.org, simply click File, Open File, select your modified .xpi file and click the Install Now button. At this point, unless you made any mistakes or any other problems were detected during installation, your addon is installed and will be ready for use when you restart Firefox. The procedure is same for Thunderbird addons.

As I said, problems are rare, however you don't know everything the programmer did when writing the addon, so monitor everything carefully until you are sure everything is functioning as it should. There may be specific features in different releases of Firefox or Thunderbird being used by the addon programmer which might really make the addon incompatible with a newer release. In general, unless there is a major change, most things should be safe. The real point is, be careful, and keep backups so that you don't have any reason to curse yourself for making the change, and me for telling you how to do it.
