Getting errors trying to pair firefox extension with keepassx w/keepasshttp

[NitrOP7674]

Everything was working perfectly until today. It may be that I recently made changes to my keepass database on linux (to add integration between keepassxc and their extension) or on my android device (to change a password), which I rarely do.

Now when I click on the extension icon, it pops up a "new key confirmation" dialog in keepass. When I name the key, it seems to work, but the next time I click on the extension, it does the same thing with a different key, and never will let the keys be exchanged.

Seems like the same symptoms as #55 but different browser and different integration, so could be unrelated.

I tried restarting firefox and keepassx.

I ran the debug console for the extension and initiated a password request, and got the following error:

Error: response is not valid

I have v0.8.1 of the plugin, v1.8.4.2 of KeePassHttp, and KeePass v2.57, and Firefox 129.0. Let me know if you need any more information or would like me to try anything else. And thank you for making this excellent plugin!

I was able to fix this by doing the "factory reset" in the extension's options -- in case anyone runs into this issue later and is searching for the solution.
