Problem: Article: Visit https://www.mozilla.org/en-US/plugincheck/ to check the status of your plugins. If you see any Update Now buttons, click them and wait for them to update. Restart Firefox once finished. Plugins can increase CPU usage when you view videos, PDFs, or other media. Once all of your plugins are up to date, testing them is pretty easy:  Visit the Plugins tab of the Add-Ons manager. Click each drop-down menu that says "Always Activate" and set it to "Ask to Activate" instead. Browse as usual. You will see a small popup every time a plugin asks to be activated. If you say "Yes" and your CPU usage rises, that plugin is the problem. When the problem is identified, look for alternative plugins for the same format. If there are none, leave that plugin in "Ask to Activate" mode. One solution is to block media you don't want to see in the first place. Try these extensions:  If Flash causes the problem, install Flashblock. If JavaScript causes issues, install NoScript. This will take some hands-on effort at first to disable problematic scripts one by one. For a generally lower CPU load, install Adblock Plus or another ad blocker. . If all else fails, return your Firefox to default state. This will permanently delete your add-ons, but most preferences and bookmarks should remain unchanged. To do this, return to about:support and click Refresh Firefox. You may want to try the other issues below before you resort to this. If Safe Mode fixed your issue, however, add-ons are almost certainly the problem.
Summary: Update your plugins. Adjust plugin behavior. Install new extensions to disable problem content. Reset Firefox

Problem: Article: An alkyne is a hydrocarbon chain that contains one or more triple bonds between carbons.  The suffix at the end of an alkyne should always be -yne.  The parent chain of an alkyne must contain any carbons that are triple-bonded.   Number it from the end nearest to a triple-bonded carbon. If you're dealing with a molecule that has both double and triple bonds, start the numbering from the end located closest to any multiple bond. In addition to noting where substituents are on an alkyne chain, you must also note where the triple bond is.  Do this such that the lowest number on the triple bond is used. If your molecule contains double bonds as well as triple bonds, you must locate these as well. If your parent chain has two triple bonds, the name will end in "-diyne."  Three is "-triyne," and so on. As with alkanes and alkenes, you  must list substituents alphabetically in the final name.  Exclude prefixes such as di-, tri- and delta-. If your molecule contains double bonds as well as triple bonds, the double bonds must be named first.
Summary: Learn what an alkyne is. Draw out the molecule. Locate the parent chain. Note where the triple bond is located. Modify the suffix based on the number of triple bonds in the parent chain. Name the substituents alphabetically.

Problem: Article: The most important element of a great outfit is fit. If it doesn’t fit you, it won’t look good, no matter how nice it is. Always buy clothes that fit you in the shoulders and waist, and has sleeves and legs that are the right height for you. Don’t worry if you’re having trouble finding something perfect--you can have most clothes altered! If you’re going for black tie, you’ll need your very best clothes. Men should wear a black tuxedo with a white shirt--no ruffles, brightly-colored jackets, or flashy bow ties. You can wear a cummerbund in a darker, discreet color like burgundy, navy blue, or forest green.  You can rent a tuxedo at any formalwear store. There is also a much more formal dress code called white tie, but it’s unlikely you’ll ever see it at a casino. Formal and semiformal outfits don’t need to be as fancy as black-tie ones, but you should still make sure you look nice. Men should wear suits with ties. For semiformal, you can skip the tie, but be sure to wear a dress shirt and a blazer. If you want to wear dressy-casual or casual chic (they mean the same thing), you can be a little less formal. Men can wear khakis and dress shirts or even jeans with a sportcoat. A good guideline is to think of something you would wear to a beach wedding, someone else’s graduation, or a nice lunch outing. You will need to wear black dress shoes for formal and black-tie casinos, but you can wear other colors for semiformal and dressy-casual places. Your shoes should match the main color of your suit--black shoes for a black suit, brown for a brown suit, etc. Sneakers and flip-flops will almost never be appropriate for any casino. The only exceptions would be gaming bars and possibly beachfront casinos. Menswear doesn't accessorize much, but the casino is a great place to try something a little out of the ordinary for you. Unless the casino has a very strict black tie dress code, you can wear jewel cufflinks, bright ties, and even bolo ties and cowboy hats to most casinos. It’s always a good idea to have a backup just in case. In the time leading up to your casino outing, you might lose or damage your clothes, go through a weight change, or simply just change your mind. Keep a backup outfit handy, or at least know where you can get a quick replacement.
Summary:
Look for fitted clothes. Dress for a black-tie night out. Choose a formal or semiformal suit. Wear slacks and a dress shirt for dressy-casual casinos. Pick shoes that match the formality your outfit. Choose accessories that complement your clothes. Keep a backup outfit in mind.
