How do I disable the plug-in checker at Firefox (3.6) startup?


There was a previous thread on this topic, but it was closed before it was answered. Even though I have an older version of Firefox, Mozilla has changed it so as to start a plug-in check screen every time I open Firefox. It is really annoying, since all my plug-ins are up to date, and Firefox starts with the update tab instead of my home page tab. Please tell me how to disable this!!!!

hello phoggard, the 3.6 branch of firefox is no longer supported - the problem you're describing shouldn't occur in current versions, so please Update Firefox to the latest version & see if this already solves the issue.

Are referring to extensions compatibility check rather?

If that is the case then you should not use the same Profile with the ancient 3.6.28 and the new 18.0.1. If you want to use both then use a separate Profile for each.


The word Plugins refers to say Flash, Java, Quicktime etc and not Extensions.

Madperson, I'd be perfectly happy with Mozilla not supporting version 3.6 if they would actually leave their fingers off it. This plug-in checker screen on startup just started a couple of weeks ago, long after they supposedly ceased supporting it. One reason I don't want to switch is that some of my add-ons don't work with the newer versions of Firefox (which, unfortunately, we have on our other home computer). Whatever my reasons, Mozilla should not be purposely trying to make things more difficult.

And james, no it's not a compatibility checker, the one that shows up every time a new version is downloaded and installed. It's a screen (evidently not pushed onto your firefox) that lists all plug-ins (like Java) and whether or not they've been updated to the latest version. Once, OK, but it happens everytime I start (even though everything is updated). How would you like it if you expected your home screen and every time you got, say, a knitting site (or pick something else that might be more irrelevant) that you had to close before you could start to work?

This needs to be sorted out. Immensely annoying.

I'll move to another browser if it persists.

this should not happen in current versions (firefox 20) - if you get the plugin check page on each start of the browser nevertheless, please make sure that your homepage is set correctly in firefox/tools > options > general.

See these articles for some suggestions:

Firefox supports multiple home pages separated by '|' symbols.

  • Tools > Options > General > Startup: Home page

If you do not keep changes after a restart then see:
