Banks and Firebug

I had a prob­lem with online bank­ing; every time it got to the sec­ond­ary pass­word check on the login screen the whole browser froze. Com­pletely. Leav­ing it to sort itself out did­n’t help. And the bank had no idea; they just said “we’ve tested on Fire­fox on Win­dows XP, it works for us”. And it prob­ably did. Even­tu­ally I got sick of hav­ing to use anoth­er browser and tried the old debug­ging standby of turn­ing off all the exten­sions and add-ons. Lo and behold, it was some prob­lem when Fire­bug was act­ive. Not a big issue, just an annoy­ing one. Not annoy­ing enough to run around fil­ing bug reports every­where, but some­thing to keep in the back of my mind (and on this blog) for future reference.
