Many web hosts rely on ads for most of their revenue. Consider disabling ad block on sites you'd like to support. . Click the menu icon (three horizontal bars), then the help icon (?), then Restart with add-ons disabled. If Firefox runs much faster in Safe Mode, a faulty add-on is slowing you down. Enter about:addons in the address bar, or click the menu icon (three horizontal bars) and select Add-ons. Disable one add-on at a time, and browse for a while to see if it speeds you up. Visit the same page to remove the add-on permanently or re-enable it, depending on your test. If you have a custom theme, it could be slowing down your browser. Visit the Appearance tab on the add-ons page, and switch to the default theme. If you've just closed a bunch of tabs, Firefox might lag for a while until it deletes the contents of those tabs from its memory. Get rid of them right away by visiting about:memory and clicking Minimize memory usage. The cache is another feature that speeds up browsing in general, but can slow you down if it gets too full for your hard drive. To adjust the cache size, visit about:preferences#advanced, click the Network tab, and check "Override cache management." Increase the cache if you have a fast drive with plenty of space, and reduce it to about 250MB if you have a slow or mostly full hard drive. Clearing your cache every couple months is a good idea, or whenever your browser gets unusually slow. You should also clear the cache before reducing its size. . If you are experiencing major slowdowns on a broadband connection, you might have to reset Firefox to remove a buggy add-on or setting change. This will delete all your add-ons, themes, and download history, and return your settings to default. Visit about:support and click Refresh Firefox, or see this article for more detailed instructions.

Problem: Article: The cell membrane of an animal cell is not a perfect circle. You can make the circle misshapen or oblong. The important part is that it does not have any sharp edges. Also know that the membrane is not a rigid cell wall like in plant cells. Cell membranes do allow molecules to pass in and out of animal cells. Make the circle large enough to decipher all the organelles you draw inside. Detailed animal cell models may also include a pinocytic vesicle on the cell membrane. This will appear as a small bulbous shape. It should push into the outer circle of the cell membrane without breaking it. In pinocytosis the cell membrane wraps around extracellular fluids (those outside the cell). It then pulls the fluid into the cell for digestion or absorption. This is why you draw the vesicle as a bulbous shape that the membrane has wrapped around. The nucleus is one of the larger structures of the cell. Form the nucleus by drawing two circlesa larger circle that takes up around 10% of the cell with a slightly smaller circle inside it. The nucleus of an animal cell has pores in it called nuclear pores. To represent these pores, erase three or four small sections of each circle. Then connect the outer lines to the inner lines. The finished product will resemble curved cylinders that don't quite touch. This outer shell of the nuclear membrane is also called the nuclear envelope. To make a highly detailed cell model, put several dots on the outside of the nuclear membrane to represent ribosomes that attach to the membrane. The nucleolus is at the center of the nucleus and makes ribosomal sub-units that combine elsewhere in the cell. Represent the nucleolus with a small shaded circle. Most of the rest of the nucleus interior should appear as one big squiggle. This squiggle represents the chromatin material such as DNA and proteins.
Summary: Draw a simple circle or oval for the cell membrane. Draw a pinocytic vesicle. Draw two circles for the cell nucleus. Draw a small shaded circle for the nucleus. Draw a squiggle for the chromatin material.

There are many options for pranks and a lot of them involve physical humor. Come up with an idea that is funny and will keep your friends laughing for days. For example, you could try one of these pranks: Put toothpaste on your friend's fingers, then tickle their face. You could also use peanut butter or whipped cream. Put shaving cream into his/her shoes. If someone opens their mouth to snore, squirt sour spray! Draw on them with a black (not permanent) marker. Make a silly design on their face or arms. Anything you can access without waking them up. Draw a mustache and a beard. Just make sure it is the kind of marker that will rub off easily. Prank calls are a great way to create hilarious memories with your friends. Just make sure you don't call anyone that will be offended by your prank call. You should only call people who will appreciate the humor since it's all in good fun. Try calling someone and asking someone if their refrigerator is running. When they say yes, tell them that they better go catch it! You could also make prank calls using the cell phone of a person who already fell asleep at your sleepover. Just make sure you don't do anything that could get them in trouble. Pranks that scare someone for a moment can be hilarious. But be careful to keep the joke lighthearted. You want the people that you prank to be able to realize it is a joke right away, rather than being legitimately scared. For example, you could try one of these pranks: Put makeup on your face to make yourself look like an insane clown. Then wake up your friends! Hide in the shower behind the shower curtain and pop out when someone comes in to use the bathroom. Just make sure to do it before they start using the bathroom to avoid any awkwardness. Sometimes people do funny things in their sleep and it can be really funny to record it or to talk about it the next morning. But, even if no one does anything funny in their sleep, you can always pretend they did as another prank! Tell someone they said funny stuff in their sleep. For example, you could tell your friend that while he was sleeping he said, "I love the lunch-lady". If someone is a terrible sleep talker, record the funny things they say.
