Think before Calibrating Macbook Air

If you are having a 2011 Macbook Air, would suggest you to think again before calibrating the battery of your computer.

There are numerous posts about the ways and advantages of recovering battery condition through calibration.  They worked nicely on my previous Macbook Airs, but not on the 2011 model.

I did three times on my machine last year, and each time the battery health status dropped even a bit further after calibration.

Three times are more than enough.  I stopped doing that since last November.  And up to now, the health of my battery remains unchanged.

Probably the battery used on the 2011 Macbook Air is different from before.

Anyway, just a note :  Do think before you calibrate the battery of your 2011 Macbook Air.

Update on May-4:
The health of the battery is getting better from 95% to 96% after keeping the machine running as normal discharging and charging usages.

How to Make Incompatible Thunderbird Addons Compatible

Despite new features and potential performance gains, every major update from Mozilla’s Thunderbird is almost certain that some addons will be disabled due to version incompatibility.  It is very frustrating especially when some of these addons are key to one’s system.

Here’s how to quickly make incompatible addons compatible:

1. Locate extensions folder under the Profile folder of Thunderbird

2. Rename the file-extension of the addon to be modified from xpi to zip

3. Unzip the file and look for “install.rdf” inside the unzipped folder

4. Open the file with a text editor and edit the number of <em:maxVersion> to Thunderbird’s current version or higher

5. Save the file and then zip the whole folder

6. Rename the file-extension back to xpi from zip

7. The addon will now be compatible to the new version of Thunderbird

•   Although the addon can be used now, there may still be a chance of features incompatibility.
•   Same principle applies to make incompatible Firefox addon compatible.
• Location of Firefox Extensions is:
\Users\<user>\Library\Application Support\Firefox\Profiles\uzc25jg1.default\extensions
