Firefox Extension Incompatible? 2006-12-23 12:02

Rename, unzip, compatibilize, zip-up, use

Just updated to the latest version of Firefox only to receive a message that your favorite extension is not compatible? Of course, the best thing to do is to check the same exact place where you downloaded the extension – to see if there is a newer version. If there is not, a friend showed me what you can do in the meantime, before the particular developer releases a newer version.

  1. Download the extension instead of directly installing it. (You know, right-click and Save Link As…)
  2. Rename the extension from filename.xpi to filename.zip.
  3. Unzip the extension, and open install.rdf for editing.
  4. Change the em:maxVersion parameter value to include your version of Firefox, better yet, change it to 4.0 just to be safe.
  5. Save the file, zip up the folder and rename the new filename.zip to filename.xpi.
  6. To install it, open the filename.xpi file with firefox.

    Beautiful tip, though scary. The new theme made me laugh (I linked over here from Topher's blog), though it is not the easiest to understand. I am guessing a search box would kind of ruin the effect? : – )
