When I use the arrow keys in firefox to go forward and back, the cursor erases tiny pieces of letters.

Even within this field of text that I type, everything is normal, but a back using the arrow keys (and then spacing also forward using the arrow keys as I go back to typing) deletes chunks of the text. Once I have started typing again in this area, the components are deleted to normal. This effect can be captured in a screenshot. After inspection, it seems to be a second invisible cursor, a character to the right of the cursor visible. So when the back arrow back, the invisible cursor trails that visible, destroying the text behind. When the spacing before using the arrow keys, the text gets fact sinking in front of the cursor visible.

Try turning off hardware acceleration.

  • Tools > Options > advanced > General > Browsing: "use hardware acceleration when available.

If disable hardware acceleration works then check if there is an update available for your graphics display driver.

  • When to use the cursor for loop and the cursor (open, fetch, close)

    Hello world
    I have a small doubt about when to use the cursor for loop and when to use the cursor for loop and the cursor (open, fetch, close).
    Well, I'm not the difference between implicit and explicit cursor. So please tell me how I got to know, what to use and when?




    Kind regards

    All SQLs are analyzed, stored and executed as cursors. Thus, you will always use a cursor.

    The problem is that languages, such as PL/SQL, provide different interfaces to interact with the SQL cursor. As the ref, the slider interface, the interface DBMS_SQL slider interface and so on.

    Each of these interfaces offers different features. For example, using the interface DBMS_SQL allows binding dynamics and dynamic recovery. The Ref Cursor interface allows your code PL/SQL pass a handle to a reference pointing to the SQL cursor, to an external client. Etc.

    The fundamental reason for the use of an explicit cursor interface is mainly that you own and manage bulk made extraction output provided by PL/SQL cursor.

    With a cursor FOR , the motor loop of PL/SQL optimize the loop by extracting block a 100 lines both. However, you cannot access this collection in bulk directly inside the loop.

    With an explicit cursor interface, you specify the size of the extraction in bulk via the clause LIMIT , and you set the variable of collection to use. This allows you to use the collection directly variable inside the loop.

    However, the need to do - code manually in bulk collection - rarely occur in the daily programs in PL/SQL. A line of treatment is both slow and not well fits. And even if your bulk code collects lines, these lines must still be processed one at a time in your code. It is much more efficient and scalable rather write SQL code, and make the engine SQL the line of treatment for you.

  • Print layout on screen rotation when you use the arrow keys

    I must have accidentally pressed a wrong key combination.  Now, when I use the arrow keys on the keyboard while typing of text, orientation changes screen, according to which key I hit it, I hit the down arrow, the text on the printed page rotates 180 degrees.

    How can I fix it?

    Thanks for your reply.

    I googled the question of fun and learned you can hit CTRL + Alt + an arrow key to change the direction of the display on the monitor.  Pressing on the same new keys cancels the function.  I must have accidentally done to create the mess in the first place.

    I've done the same thing if I had rebooted the system.

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem.

    • Put yourself in the DEFAULT theme: Firefox/tools > Modules > appearance
    • Do NOT click on the reset button on the startup window Mode safe

    You can also try another mouse in case there is a problem with your current mouse and check the double-click setting in the mouse driver software.

  • How to change the search engine when you use the functionality of Firefox Home button Search?

    In Firefox itself, I have configured duckduckgo as my default search provider.

    But when I use the host Firefox search button it is always defined on google and I don't see any possibility to change that?

    I love the Firefox Home button Search (or whatever we call it) otherwise, but it's annoying that it does not use the default Firefox.

    I use the Google Launcher now.

    Hi mrt181, it is planned to use the same search engine as in firefox - however, there is a bug at the moment, so it does not apply in all situations.
    usually, it will be enough to change the default engine in firefox back once to work around the problem in the search widget and get the same as set in the browser search provider.

  • How can I stop Firefox from sinking my IP when I use the proxy settings?

    So basically I use settings from manual proxy on Firefox from time to time to be more anonymous. These proxies are normally rather slow (but hey, it's the price for you to pay for anonymity). Sometimes I'll see a sudden leap of speed. I suspected that the proxy may not work for some reason any. So, I use a website that tells you that your IP address is to see if the proxy settings are really working. Of course when I update the site it gives me my real IP. I have check the proxy settings and it turns out that the browser was restored to use the proxy settings of the system (for some reason that is the default instead of no proxy). This happens randomly and why not apparently when I use the Manual proxy settings and it flees my IP every time that happens (and I never know when it does, unless I am very attentive). Is it possible to prevent him from returning to the system without no reason proxy settings? BTW, I tested the proxy in question after what is happening so it still works which preclude the possibility of the proxy does not (even if that were the case, I'd rather my IP don't Connect at all that the leak). So yes, any help in getting it to stop doing that would be nice.

  • When I use the printer icon in Firefox, it is pre-set to 10 copies. How can I change this default single copy. Thanks for any information

    When I use the printer, in the upper left corner icon, it is automatically preset to 10 copies. I want only default copy. I can change it to one, but when opened, he's back to 10.

    Number of copies to print is not a parameter that Firefox is supposed to be saving, and I've never seen a preference for this in Firefox preferences panel hidden - about: config.

    Try of the reset described here and reset all the preferences for this printer:

    http://KB.mozillazine.org/Problems_printing_web_pages#Reset_printer
    Be sure to restart Firefox before you see if doing this reset solved your problem.

    If it solves your problem, please click the button solved it next to the answer that meets or solved your problem of Firefox support, it appears when you are connected, so this thread is marked as solved to help other users who may have this same problem.

    If that does not solve your problem, and defaults to always print 10 copies of everything through Firefox, please open help > troubleshooting... information and use the copy to the Clipboard and then paste this information into the box post an answer here.

    It's going to be a real long list, but all that I really need to see is the printing preferences, so you could paste all the information in a program such as WordPad text first, change the information that I can't see and then copy the remaining information and Paste only the information in the box to answer here.

    I wonder if there might be a pref I've ever seen, but I really doubt it. "Number of copies to print" has never been "stuck" for me on any program in Windows, on any PC I've ever used with any printer / print drivers.

    The only time I've ever seen a default "print dialog box" more than 1 copy has been with a working application where the program has been to force 2 copies of specific forms to print 2 copies all the time--one to give to the "subscribed" at the end of employment for their documents to the service call and one for the 'employee' obtain a signature at the end of employment with a fax in the Home Office for documentation of the task as completed successfully and for the purposes of the payroll while they would have paid for this service call.

  • Remote Desktop, response delayed when typing using the SHIFT key

    I have a laptop running Vista professional that I used to connect (DSL) to a desktop computer using remote desktop (XP) work.  Several months ago, I started noticing a response delayed when typing using the SHIFT key. For example my name, Garth, might get typed Garth, the text could (for example) get typed as 9 example0 and so on. The delay of the effects as well the pressed ALT key and assigns these keys on both sides of the keyboard.
    I did not used to have this problem and wonder if an automatic update to my laptop (vista) could have caused this problem. This problem does not exist when I connect the laptop using office away from my local Starbucks. My other laptop (older) doesn't have this problem at home or on the go.

    Well Garth, it seems that the problem may be with your home network if you have 'no' to this question when connecting to a local Starbucks.

    While you're at home with this laptop and connected to your DSL, it is a problem if you are 'not' connected to the desktop computer?  Or is it a problem regardless of whether you are connected or not connected to the work computer?
