Firefox 7 Successor Firefox 8 allows to restore tabs on demand, disables third-party add-ons by default, adds twitter as a search engine to the search bar and offers improved tab animations besides all that when you upgraded from Firefox 7 to 8 you’ll be presented one-time add-on selection dialog to to select the add-ons you wish to keep or disable, this will happen only once and not for each time when you start Firefox.
This is good for Firefox users protects from third-party malicious add-ons, even though there are legitimate cases where security software installs add-ons without user consent. If you’re a bit confused and you’d like to tackle third-party add-ons on your own and you don’t want to view the add-on selection dialog when upgraded from Firefox 7 to Firefox 8, here is how to disable it.
Disabling Firefox Add-on Selection dialog
1. Type about:config in address bar and proceed forward by agreeing to the warning.
2. Type or paste “extensions.shownSelectionUI” opposite to Filter, double-click the preference and turns its value to False.
This preference exists in Firefox 7.
the disable trick does not work for me with firefox 8.0!
when i use the prefs.js i used with firefox 7 and install firefox 8 – i get the add-ons selection dialog. (with or without extensions.shownSelectionUI set to false)
i would like to stop the add-ons selection dialog for all my users, but if i deploy 8.0 everybody will get asked which extension he wants to get enabled and which he does not.
bad for a company where all users should use the same extensions…
Exactly same thing for me. I tryed some other way. The add-ons selection dialog is shown regadless of what I try. If I find, I’ll post the solution.
Above fix didn’t work, however,
I was able to fix via:
editing one of the prefs.js (there may be a few that get used depending on the config of your workstation)
1. add a # in front of the user_pref(“extensions.enabledItems”) “”
2. add a # in front of the user_pref(“urlclassfilter.keyupdatetime.https:sb-ssl.google.com/safebrosing….
save the edits
copy this file to all other prefs.js in other directory’s (if multiples exist)
The funny thing is, the setting extensions.shownSelectionUI should be set to “true” to disable it.. The setting seems to indicate whether the dialog has already been shown, so by setting it to true it won’t be shown “again”.
Worked for me. You can also add it to prefs.js as:
user_pref(“extensions.shownSelectionUI”, true);
Hi
Yes it disables the box from appearing but then tabs load on first run showing the add-ons installed and users can make changes ie: Menu Editior Add-on which I don’t want users to be able to change same with iMacros.
Thanks Mark
