weird. I know can suck, especially if you have lots of extensions and stuff, but I would try doing a completely fresh install? remove chrome and google how to remove any lingering bits of it on your computer too and then do a clean install. if it's isolated to just one device/browser for you at least? seems like something went weird on that device than ij itself. run a malware scan too - malware bytes is pretty good. you may have picked something up that is just causing your browser/computer to glitch out.
