Yesterday, I received a pop-up for a firefox security patch. It was only a 428 KB patch entitled liirawynagrodzenia.net. Is this legit??

My question above pretty well explains my problem and concern. The pop-up read "firefox-patch.exe". I presumed that it was a legitimate update - - - forgetting that Firefox does automatic updates. So, I did the download. Now I'm concerned that this is not legitimate, and I should not have done it. Please confirm if this is the case, and what my solution should be. I see nothing different on my Firefox home page. And, it seems to be operating normally. Thank you. WFBsr

No, that is an attempt to spread malware that has been ongoing for the last few weeks. You should immediately delete the file you downloaded, and run scans using all the tools at Troubleshoot Firefox issues caused by malware

Also, if you installed that patch, I suggest you uninstall Firefox and install it using a fresh file from www.getfirefox.com.

Mozilla doesn't patch Firefox. "Fixes" are done via an update - major or minor version updates - and that is done via a .mar file that Mozilla installs automatically. Nothing for the user to save and then install manually, as with a file like malware that might be named "firefox-patch.exe".
