Seems to be the time of the year where not only the nights but also the titles of my blog become longer and longer. I found something useful for all of you. I had the problem that some of my beloved firefox extensions would not work with firefox 1.5 until they were updated by the extensions programmers.
I had no intention to wait and thought of installing a firefox 1.0 version next to the new 1.5 but lucky Martin found a site that explains how to make firefox extensions that do not work with your firefox version work in your firefox version. Hehe, that sounds complicated somehow, lets see how this is done..
1. At the location bar, enter: about:config. This will show you a list of Firefox internal preferences.
2. Right-click on the list, select New > String
Enter “app.extensions.version� (without quotes) for the preference name.
3. Then, enter “1.0� (without quotes) as the value for app.extensions.version.
4. Restart Firefox 1.5, then enable those disabled Firefox extensions.
5. Restart Firefox 1.5 again to active the extensions. Done.
Thats it, five easy steps and every extension should be working like before. Thanks to the guys at dancameron.org

[...] My extensions list includes over 15 beautiful extensions but 5 of them did not work with the new fox. I’m looking into converting them (if that’s possible) or finding replacements. Technorati helped me find a way to make them work. [...]

I wonder if that would cause any other unforseen problems wiht the fox.
I´am not sure. I suppose it could be that some firefox extensions won´t work even though you changed this, maybe because firefox changed how it handels extensions.
I can´t tell but I think it won´t hurt much, if you encounter a problem simply undo the changes and everything should be back to normal..
I don’t recommend trying this. I did, and I got DLL errors with the extension I enabled. Firefox would open but it wouldn’t run correctly, and other extensions wouldn’t work. I had to go and reset the about:config entry, uninstall the extension, and reinstall Firefox 1.5 to get it all working again.
all the extensions i tried did work, which was it that did not work ben ?
