I'm asking about FF2 here because (1) I feel it's still a very relevant (and very functional) browser for win-98, and (2) nobody in any mozilla forums wants to talk about old versions of FF.

I installed the "remember mismatched domains" addon a while ago, but I find for the past few months that I have to keep dealing with dialog boxes for domains that I've already told FF to remember my instructions to ignore the domain mismatch. These seem to be for domains I've put in my hosts file. I'm not sure if it goes beyond that, but I do have Abyss web-server running on the local machine, serving up local copies of js files for these domains (such as apis.google.com).

Does anyone here run FF2 (2.0.0.20) with that add-on? Are you dealing with the same issue?

(in case you're wondering, I've tried FF3 but it screws up bit-mapped images on web-pages when you scroll them up and down, so I still use FF2 as my default browser).

Maybe check if the certificates are indeed saved (that's what I understand this addon should do?). BTW, a possibly better browser for Win9x is Opera 10.xx.
