Hello and welcome to Android Forums. Hopefully I can help you with your problem.
Ok, here's what I would do. I would open up your device settings. Find your apps then locate your browser. Choose to wipe or delete all the data. You'll lose all your settings but your can go back in and set it back up.
Another alternative is to try a different browser. There are plenty nice ones on Google Play to choose from.
If you are experiencing issue while not using the browser too, I would actually do a factory reset on the phone. If you are rooted and have a recovery like CWM or TWRP, you'll be ahead of the game and should know how to do a factory reset.
If you are not rooted, you can still do a factory reset with the phones stock recovery more than likely. You'll have to create a new post with more info.
Without knowing the model of the device, I cannot give you the exact steps needed. If you would like, make a new post stating model. Also let us know it's an LG like you did this time. Let us know whether or not you are rooted, what recovery you have, etc. We'll need a good bit of info to properly help you solve this if you want to continue here.
I ask you to browse through Android Forum's list of devices. If you see yours there, I wold like to invite you to join our awesome site. We have a wealth of information on many devices. By becoming a member, you'll have all the info at your fingertips PLUS a community to answer any other questions you may have.
Hopefully the information I have provided above will help you out by either wiping the browser data or doing a factory reset. If not, I invite you to choose one of the other options mentioned.
Good luck and I hope this info helps you. I am going to mark this post as solved due to the fact that there was no model mentioned. Please make another post with more detailed info about how your device is set up or better yet.... join our community.
Thanks WB7
