Tag: Firefox extensions

When Firefox 3.6 detects a network connection issue, it switches to offline mode.

I find it rather annoying as it forces me to manually switch to “online”  mode via the file menu each time I replug my laptop.

This behavior can be disabled via a hidden preference.

Type about:config in Firefox address bar, right click to add a new Boolean key and create

network.manage-offline-status

set it to false

Alternatively you may add an extension for this: https://addons.mozilla.org/en-US/firefox/addon/13152/

When upgrading firefox, I cannot use extension which have not been flagged as compatible with the new version yet (open book for example).

Just add an entry in the about:config page to let firefox run it (at your own risks )
Add a boolean entry:

extensions.checkCompatibility.3.6

and set it to

false

The syntax evlolved since firefox 3.6 (the version number was not mentionned explicitly before).
Refer to http://le-moulin-de-verre.com/fieldnotes/?p=111 for firefox prior to 3.6.

The last version of firefox is out, but an extension that I use daily (QuickProxy) has not been updated yet. In fact, it should work but it is considered ‘not compatible’ by firefox and thus, is automatically de-activated.

The workaround (at your own risks !) is to bypass the security that enforces the compatibilty of extensions.

• Open firefox and enter  “about:config” in the URL bar.

• Right click in the page, then “new->boolean”

• enter “extensions.checkUpdateSecurity” as the preference name in the dialog

• set it’s value to false.

• Create a similar entry called “extensions.checkCompatibility” set to false too.

Be careful when testing unsupported extensions, you may want to activate them one by one ! However do not hesitate to try, I have been able to succesfully use QuickProxy this way for more than a month….

For the record, the list of all the about:config options of firefox.

[EDIT:] The extensions.checkUpdateSecurityallow the download of extension without SSL, and is not related to firefox version check. It should remain to true http://kb.mozillazine.org/Extensions.checkUpdateSecurity.
