How to close tab on browser

From the home screen, if you look at the bottom of the screen.. the square which is second from the right should bring up all apps currently and previously used. You should be able to tap the X on the top right of each app box to close them individually. Alternatively, opening a browser window then to the right of the address bar is the amount of open tabs you have.... tapping on the number should bring up the open tabs... give them all a little time to completely load up, then you should be able to close them the same as above.
Hope this helps you solve your problem :)

Too many Chrome browser windows open (You didn't say that, but I'm guessing that's the problem. Press the overlapping-windows symbol at the top right.

Go into the settings for Chrome, or your internet browser and make sure that cookies are enabled. Clear out all old cookies and clear the cache. then close the browser, make sure you go to ram manager and close it out so its totally closed and not just "minimized" in the background(if you don't know how to do this part then just restart the tablet) then start the browser back up, and try again

Does this only happen with a single web site, or is it any web site with drop-down menus? Have you tried a different browser, such as Chrome or Dolphin? What version of Android is on your tablet?

your browser should have a tools tab, try adjusting the font size there.... the browser is what you use to access the internet
