As bloggers, we do blog walking once in a while. Sometimes we even exchange G+, FB Likes, Tweets etc. but some of the blogs that we visited have templates that don't show the G+, FB like, twitter widgets. Worry no more! There's a very easy solution on how to make them appear.
If the blog has heavy images, or does not show the widgets you can simply do this:
Press Control - ( Ctrl -) to make the blog smaller
What I do if the blog has heavy images and doesn't load fast: I keep on pressing ctfl - until everything appears, I then press
Press Control + ( Ctrl+) to make the blog bigger
When you zoom out the blog post the widgets load more easily. No need for you to refresh the page over and over again.
After the widget appears you can now zoom in the blog post so you can click on the widget.
Try this! Happy Blogging! I hope I was able to help.
