I deleted a bunch of certificates. Now I can't get into web sites. I tried reinstalling firefox. No joy. John

Hi steeldrv, you can remove Firefox's certificate store file (cert9.db) and let it generate a new one. However, if you mention what is happening now -- do you get an insecure connection error page? -- there might be a different workaround. For the steps to replace the cert9.db file, see the "corrupted certificate store" section of the following article: [[What do the security warning codes mean?]] That article also lists possible fixes for other issues. To find the particular error code, you might need to click an "Advanced" button on the error page.
