How can I only use html5 to play videos instead of flash (which is what I would like to delete)?

I have firefox 50, I am aware that most of the Web site I visit can offer videos with html5 (and that the flash is used only if it is installed, it is 100% correct in the mobile world) so I would like to have firefox using default html5 instead of flash (which is what I would like to withdraw as soon as possible). Thank you

  • How can I change where Firefox seeks its saved data from cookie/bookmark/password? I would like to move these files to an encrypted drive.

When I drive, I wish I could tell Firefox to consult about it and find the data in profile automatically.

    How can I connect using adminastrator account?

    By design, the only way to connect to the built-in Windows XP Home administrator account is to restart in Mode without failure.  For WinXP Pro, by pressing CTRL + ALT + DELETE twice at the Welcome screen will produce the standard login dialog box.

  • How can I search using a word or phrase in the file?

    I can't find anything using windows 7. How can I search using the old option to find "a word or phrase in the file" when I don't know the file name, type, or location, as we could do in XP and all the previous versions?

    Hi rayf1967,

    I was back tonight, saw your post and tried a search in my .xls and .xlsx files.  They results were not as I suspected.  But now is a result of the work.

    I had left the 'files allow on this drive to have content indexed in addition to file properties' unchecked.  This means that my old index was sought but changes or new files were not included.  When finally, I went to properties and permit of indexation for the drive, I could search for .xls and .xlsx text files inside the cells and inside the text boxes.  I edited my last post to include this observation.

    Window 7 file & directory search success
    Yahoo! I finally successfully a text file for a search string.  Thank you Lisa and Thahaseena I have studied the links and then did some testing over a period of 5 hours.  FYI, I get using the old DOS commands in .bat files.  Understand the new search engine was much more difficult than learning a RegEx in the 1980s.

    1 CAUTION: The box of the property known as the disk:
    "Allow files on this disc have content indexed in addition to file properties"
    This check box controls the update of the data base of the index.  It must be checked to build or update an index that may be searched.
    You can select the entire disc or only a subset of records.
    For discs:
    RT-click file / properties
    For the records:
    RT-click File / Properties / General tab / advanced

    I correctly searched for file names and files with this box unchecked, but the results do not include the files created or edited since the last time the index was built or in other words since the indexing has been authorized.

    2. research in the files has N O T by default after my installation of W7.  My system keeps all the files on a non-system drive and that the drive did not appear in the search index settings. Fault of not Ms.

    3. research in the files REQUIRES that the drive/directories are specified:
    Set the locations:
    Control Panel/Indexing Options/change /-down and check any disk or dirs you want indexed.
    Set the file types you want to allow search inside:
    Panel of control/indexing options / Advanced Options/File Types/Index Properties and the content of the file - set as you wish
    The file types are grouped and there are filter categories they fall.
    Defining the .txt (plain text filter) to "Properties Index and contents of the file" will allow many other types of files to be indexed.  The same is true for .doc (Microsoft Office filter); This one will allow indexing for all Office files.
    My QuadCore 3 GHz/4 GB indexed to 2500 points per second.  I have let it run overnight on my drive of files I have about 3 hours to complete.

    4. read on "Windows Search Advanced Query Syntax" it can help you a lot.

    5 W7 will show what looks like a mistake/complaint at research suggesting that you change your settings for indexing.  This will happen even if you have defined the so ignore/disable it.

    E x a m p l e s (all text left - has been typed/pasted in the search box):

    1 test cycle after: 07/20/10 - find all the file names with the string 'test' in them with update a value greater than 20/07/10.

    2 * test*.txt after: 07/30/10 - it found only files of type .txt 'test' in the name and modifed today (30/07/10).

    3. content *.txt: citabria after: 20/07/10 - searched the citabria word in files of text changed after 20/07/10!

    4. content *.docx: citabria after: 20/07/10 - searched the citabria word within Word files modified after 20/07/10!

    5 *.xlsx content: fardap - looking for the word inside all my files fardap .xlsx; found in cells and the text box.

    Spammers use other peoples addresses all the time. It's easy. The only thing you could really do is change your address. On the positive side, they usually do this method for a few days and then change the address, then it must stop.

    You CAN open the file *.wpl with a text editor. You can (or cannot) be successful
    by making a change to the paths you will find in these files.

  • How can you set it up to play 2 songs always together?

    How can you set it up to play 2 songs always together in iTunes, downloaded on your ipod?

    You can reach consecutive tracks whole CD you rip a CD, a file which has two songs, otherwise you can not really do. There is an iTunes feature called Shuffle by grouping, but it is not the iPod.

  • How can I make the tΓches play a mp3 file at some point please?

    I would like to that task scheduler to open windows media player and play an MP3 for me at a given time. I followed the instructions here, but nothing helps. The windows media player window does not open, but it does not play mp3.

    http://www.Vistax64.com/tutorials/132903-Task-Scheduler-create-task.html

    In the program/script box, I put in "C:\Program Files\Windows Media Player\wmplayer.exe '.

    In the Add arguments box, I put in: Wildlife.mp3

    At the beginning of area (optional), I put in: C:\Reminders

    which is a folder that I created in the C drive.

    Wildlife.MP3 file is of course in the C\Reminders folder.

    I have Windows 7.

    I have Acrobat professional 9. I moved it to my new computer Windows 10. Whenever I have printed on a home printer it ask again me if I want to improve and I only have 12 days to do it. How can I get rid of him. I have a valid license. What is the cost and benefits, the upgrade to Acrobat 9 professional to the latest version (I think it's X)

    No, X is not the last. In fact, X, as 9 is now unsupported. After X XI, after that XI was DC. DC is the current version. No upgrade price from 9 more, unfortunately. You can subscribe to DC, and this is recommended because it gets new features faster and includes future updates (probably will be necessary as Microsoft moves to Windows 10 edition when they feel like it, instead of waiting for Windows 11/12 etc..)
