Firefox sometimes crashes when extension is installed.

I followed these instructions and completely deleted the extension, restarted Firefox, deleted all "extensions.dnssec.*" keys in "about:config" and restarted again before installing version 2.1.2 of the " DNSSEC/TLSA Validator" extension. https://addons.mozilla.org/de/firefox/addon/dnssec-validator/#detail-relnotes

Software used: OS: openSUSE 13.1 Linux (x86_64) Firefox version 32.0 by openSUSE (x86_64) DNSSEC/TLSA Validator version 2.1.2 (also tried version 2.2.0.1)

Another reports:

1. I've recently had to disable DNSSEC/TLSA validator (v2.2.0.1) when running in Firefox 36.0.4 'cos it seems to cause FF to repeatedly crash. Some more detail: I looked at page "about:crashes" in Firefox and picked out a couple of crash reports - the most recent and one a week ago. What they had in common was the crash reason: EXCEPTION_ACCESS_VIOLATION_READ, and the following dll highlighted in red as a possible culprit: libDNSSECcore-WINNT-x86.dll. I guessed that this might be used by the FF plugin DNSSEC/TLSA validator (v2.2.0.1). So disabled that plugin. Firefox then stopped crashing. Are the developers maintaining this plugin? If so, will they address this problem? I should say, that when the plugin worked, it was of little use to me - so turning it off was no sacrifice.

2. DNSSEC/TLSA Validator 2.2.0.1 Addon for Firefox browser causes a Firefox (version 36.0) crash if You close Firefox before a web page is fully loaded. It's always a plugin-container error.
