Make firefox addons compatible again

[Thelovefool]

Hello Community,
i think many of you have favourite addons which arent updated for the newest firefox version. But today i found a little workaround which make addons compatible again ...

1. Lets choose an outdated addon ... (eg Kaizou)

2. Go to mozdev.org - kaizou: installation

3. Right click on "Click here to install the latest version of the Kaizou Firefox Extension" and choose "Save target under" from the dropdownmenu.

4. After saving kaizou to the desktop you should see a file called "kaizou-0.5.7.xpi"

5. Rename the extension (xpi) to .rar and open the file.

6. You should see two files:
"chrome"
"install.rdf"

7. Open "install.rdf" and change this

(the red part is the part which tells firefox if the addon is compatible)





9. Winrar will ask you if you want to renew the archiv. Click on yes. (ITS VERY IMPORTANT TO LET WINRAR RENEW THE ARCHIV OR THE CHANGES WONT GET SAVED)

10. Now change the extension from "kaizou-0.5.7" back to xpi again.

11. For the last step drag&drop "kaizou-0.5.7.xpi" into firefox's favourite bar and click on the new kaizou bookmark. (the addon checker will launch and install kaizou)


This routine is for every addon file exactly the same

Hope i could help a few of you.

When I am trying to edit the values, it just sounds DONG and it won't let me to.
Yes, I use WinRAR and I've done it correctly ;o

[Thelovefool]

[Danne206]

I don't :/. You know when you try to edit something that you can't edit - I get that noise.

[Thelovefool]

hmm idk for me it dont happen
1. maybe you can rename it to rar
2. unzip files edit them create a new .rar archive with them and rename its extension to xpi?

[Ground Zero]
