I use Firefox for Android; always have, on every device since the Moto DROID RAZR. I now use a Moto DROID Turbo 2, but that's irrelevant to my problem. Ever since switching from Chrome to Firefox, I noticed that typing a search into the search box on the Google home page is excruciatingly slow. The search suggestions take forever to come up, so much so that I have my entire query input before the second letter even appears. In searching for a fix for this, someone on Reddit claimed this behavior is designed by Google and that overriding the user agent would solve it - which it did. I went to the about:config settings and created a key titled general.useragent.override.google.com which contained the value "Mozilla/5.0 (Linux; Android 6.0; XT1585 Build/MCK24.78-13.12) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.89 Mobile Safari/537.36" which is the useragent string I got while using Chrome on the same phone and surfing to whatsmyuseragent.com. So now any google.com site should see my browser as Chrome instead of Firefox and this did indeed fix my search entry problem. But now, if I search Google Images, no thumbnails will appear. I can tap the blank space, and the image will load, but as soon as I back out it disappears again. I have tried disabling/uninstalling all add-ons, uninstalling and reinstalling Firefox, and Google Images works fine until I create this "general.useragent.override.google.com" string in the about:config page. Is there anyone who might have a solution? Or is there another solution for the slow search entry on Google in Firefox Android? I can't go back to Chrome; Google's refusal to allow the mobile version to use extensions is a deal-breaker. I've got to have my ad-free browsing.
