An error occurred while trying to find updates for Addons/Updates

In Firefox Portable Edition 3.x.xx sometimes when clicking in Tools -> Add-ons -> find Updates you might get the error for the various (if not all!) Plugins/Addons you have installed from addons.mozilla.org.



My solution to this known problem is as follow...

Type the URLs below in your browser or just click on them below one by one. Let it load. You should see the certificate error just like the one below...


https://services.addons.mozilla.org
https://versioncheck.addons.mozilla.org
https://versioncheck.addons.mozilla.com
https://versioncheck.acelb.sj.mozilla.com



You simply accept these certificates permanently and after doing this you are good to go.
Simply go back to the Add-ons Update and his UPDATE and voila! You shouldn't see the errors anymore and get the updates just fine from now on.
If for whatever reason the problem starts again just repeat the procedure above.

Tweak And Optimize Firefox Speed With FireTune

You can either configure the Firefox settings manually or use FireTune. The difference is 30 minutes or more. Instead of having to tweak settings in ‘about:config’ manually, just provide FireTune with some basic details such as CPU speed and Internet Speed, and it will optimize your Firefox based on such input.

Note: Make sure you have made the backup of Firefox configuration before tweaking it with this tool. Backup and Restoration of original configuration can be made from within this tool.

It is a portable tool for Windows only, just extract the content from the zip file, open the folder, and hit FireTune executable file. You can also optimize Firefox portable using this tool, hit Settings, select Type Of Firefox, and choose Firefox Portable.

Tips: Xmarks

One of my favorite Firefox add-ons is Xmarks. Xmarks keeps bookmarks and passwords synchronized among my computers and the various browsers I use. Before the advent of Xmarks it was a cumbersome process for me to keep bookmarks synchronized among my PCs and Macs, at home, at work, or while on the road.

Tips: Personas in Firefox 3.6

Personas are a popular new feature of the latest Firefox web browser. Personas imbue your browser with various colors and themes. They give your browser a distinctive personality to suit your whim and fancy. There are more than 57,000 personas available at getpersonas.com.

Versions of Firefox earlier than 3.6 require the Personas add-on, which is now incorporated into the new Firefox version 3.6. Personas in the new version of Firefox can be viewed and changed almost instantly. I highly recommend upgrading to 3.6 which is both faster and more secure.
