I can't fill in form within TB

[mi]

Binary package hint: thunderbird

I use "ThunderBrowse" to open web pages within Thunderbird.
But when I try to fill in form, for exemple to sign a petition, it does not work !
In the name place I can only type 2 digits ( c and h for chaplin and the rest (here "aplin") goes at the bottom of the page within "move message to") ; for first name 3 digits are accepted ; no problem with "job and town of residence ; but with "address mail" only two digits are accepted again.

Uninstall or disable that extension/addon and you will no longer see this problem, the extension is at fault not thunderbird. We do not support that extesnion since we dont package it. Please see upstream author on how to fix it or if he can fix it.
