For what seems like perhaps a couple of weeks, I have had an odd situation where typing into the Google search box in Firefox 60.7.2esr (32-bit) causes the whole screen to fade somewhat until I click elsewhere on the screen (whether a link or an inactive area). Importantly, I am talking about the search box at Google.com, *not* the Firefox search box (the issue does *not* occur when I use the latter). It's kind of like what you see happen to the screen when activating the Windows Snipping tool, before taking the snip, though not quite *that* faded. In the attached image, the left half is *without* the cursor positioned in the search box, and the right half -- which shows the fading -- is *with* the cursor positioned in the search box for typing. Some points: (1) This does not happen when using Google Search in Chrome or IE. (Firefox is my default browser, BTW.) (2) This does not happen on either of my other two Windows 7 pc's, which also use Firefox 60.7.2esr (32-bit). (3) Disabling add-ons by using Safe Mode doesn't change the behavior. (4) Disabling Hardware Acceleration doesn't change the behavior. My main concern with this behavior is in case it indicates the possibility of some kind of malware. My secondary concern is whether it might indicate some other current or potential problem with my system, although I haven't noticed any other issues thus far. Other than that, I don't mind the behavior, as it doesn't slow me down or prevent me from accomplishing anything. Any suggestions or other thoughts? (I prefer not to do a reset.) Thanks.
