Visual glitch (vertical lines after the first tab) with 33 FF

Since Firefox 33.0, I have this glitch visual - a few random vertical lines that appear somewhere near first tab if only one tab is open. I tried different versions and it began with FF 33.0 and in all versions of 33. Now I test 34.0b7 FF and it seems that is not there. So I hope that its does not pop up when 34 goes stable.
Here are a few screenshots:

To make believe that I have to open two tabs, and then close the other, and this is when it appears.
These lines are blinking / moving according to the place where my mouse, for example, move the mouse over the address bar allows you to change.

Hello

What happens if you disable graphics hardware acceleration? You will have to perhaps restart Firefox for it to take effect, so save any work first (e.g. you compose mail, documents online that you are editing, etc.).

  1. Click the menu button

    then select Options Preferences on Mac or Linux, or Windows.

  2. In the window of Firefox Options (or preferences), click on the Advanced tab, and then select general.
  3. You will find in the list of parameters, the checkbox use hardware acceleration when available . Clear this check box.
  4. Now restart Firefox and see if the problems persist.

In addition, please check the updates for your graphics driver by following the steps in the following knowledge base articles:

  • Go to the first tab Alt - 1 does not

    This problem only happens "Alt - 1', Alt-2 and thus now work as expected."

    I guess the Linux operating system has supported the shortcut Alt + 1, and it is not Firefox.

  • Flashing of the vertical lines in the tab bar?

  • Firefox will open 4 or 5 thin legs, but then do not load any other sites after the first 4 or 5 or you can update one of these first tabs - including: config and the addon page

    Firefox 5 worked well. I installed Firefox 7, and when I ran, tabs just say «connecting to...» "and hang up. Rebooting did not help. Sites Web open correctly in IE and Chrome. Disabled all firewalls and antivirus, nothing helped. Uninstalled and reinstalled Firefox 5, everything has worked again. It was using Vista 64-bit.

    Upgrading to Windows 7, uninstalled Firefox 5, installed Firefox 7, had the same problem. Uninstalled Firefox 7 completely (including profile information, I saved this information in another file), restarted the computer and installed Firefox 7 using a clean profile. Do not install add-ons, checked to make sure that all plug-ins were updated and updated plugins up-to-date.

    Now when I run Firefox, I can load 3 or 4 or 5 tabs very well - after these first tabs bit are open, I can not open or refresh all other tabs - with about: config and the add-on Manager - I have to restart Firefox. The hangup does not appear to be associated with what websites I try to open, but it seems that the number is the problem. I ran through all the procedures of the FAQ, including changing the maximum number of connections to 48, and the problem does not seem to go away.

    As a side note, I had this same problem when I tried to go from version 5 to version 6 more. Version 5 is the latest version which worked on my system.

    The default value of the pref Network.http.Max - connections has been increased from 30 up to 256 in versions of Firefox 6 +.

    Try to decrease the value of the pref Network.http.Max - connections from 255 to a setting like 30 such as used in versions of Firefox 3.

  • Firefox does not open a link after the first; Open ok in new tab front.

    In the last week or two, for reasons not clear to me, Firefox does not open the new links after the first; It is used to open a new connection in new tabs (according to my preference) without problems in the past. Now it does not blink again.

    Over time, I've added new applications and others removed, and, of course, I can't exclude from their role in the problem that I have now. I would appreciate some help to solve this problem.

    You have this problem when running in Firefox SafeMode?

  • Tecra S1 - vertical lines on the screen

    Hello people,

    IM new to this forum so first all the Hi everybody ;-).

    My girlfriend bought a Tecra S1 second hand and after a few vertical lines of the month displayed on the screen. When I asked around the power button pressure lines have disappeared. But after a few minutes, the lines are back. So I thought that it was probably a problem of video and e - bay, I bought a second hand motherboard. I installed it and now after a few months I get vertical lines again. (It also happens on an external monitor).
    I opened the laptop and with only the motherboard in front of me I plugged it to a monitor outside, put a little pressure on 1 side of the motherboard and the lines where go! Would that be the case?

    I know that on ebay and other sites where they offer second-hand computers laptops MANY people have the same problem.

    Did someone had an idea? I hope that I can fix it!

    Thanks for your time and sorry for my English.

    Greetz Mark

    Hey Mark,

    I doubt that people often have this problem. I put t read often about this problem, as far as I know it s thread the first on this subject.

    In any case, I think that it s not unusual. I mean you bought a motherboard of second hand on eBay, so who knows how old she had and often it was used in the book. Second hand spare parts that s another story in my opinion. You're more or less luck with these parts.

    I would recommend so buy a new mainboard with a provider of services authorized. It seems that you can change it yourself and so you can save a lot of money. On the Toshiba site, you can find a list of ASP.

    Good luck! :)

  • CC of 2015 rubber-band layers and vertical lines in the timeline

    Greetings,

    Like many others, I feel many troubling issues with AE and first in this CC 2015 was last updated. I have a lot of problems with friction audio, audio response slow keyboard, wacky playback with a loop and being insensitive to the entrance and these preview. All of you who are on the known issues page.

    Another question I had is when I make keyframe adjustments or time to layer (by clicking and dragging them forwards or backwards in time on the timeline) they will often leap after releasing the mouse button. I can't get this repeat with regularity, but it happens... every few minutes or sometimes several times in a row. Sometimes when the timeline panel displays a different portion of the timeline, as if I did scroll up with the mouse and then wheel jumps to what I was working on a second later.


    I also have a problem with vertical lines in the timeline on playback. In this case most of the time.

  • Qosmio G10 has vertical lines on the screen

    I have a G10 which I use for the last 15 months since I bought it.
    However, there are now 4 vertical lines on the screen, 2 Purple (magenta?), 1 yellow and 1 cyan. Other than these lines there are no other problems, it never fell down or something like that.

    The lines are still there, they do not change in any way and are always in the same place. They appear on the screen at first power up, before the Qosmio logo lights up.

    They have not all appear at the same time, they all appeared individually in the past two months. I've seen the last of them disappear briefly, then stay on.

    I guess that my screen is dying slowly, I guess to be an expensive item.

    Any advice thrown my way would be greatly appreciated!

    I took a picture of the screen you will find at:

    Note: the photo was taken with Media Player full screen on a black image, just to clearly show the lines)

    Hello

    I suggest you connect an external display to check if it's a graphics card or a display problem. If cela pipes appears also on the external screen then it could also be a problem with the graphics card.
    If these lines do not appear on the external display while the display of the laptop has a malfunction.
    However, this does not change your situation. I recommend you contact the Toshiba ASP to solve this problem.

    Any response will be useful,

    thanx

    Hello

    First of all, you should check if you have the same problem on an external monitor. So you can check if the problem is the graphics card or screen.

    However, I think that the motherboard or display needs to be replaced. To do this, you can go to an authorized service provider.

    Is it possible that an extension is causing the problem?

    Try to start Firefox in safe mode to disable all extensions to see if that fixes the problem. If it does, try disabling an extension at a time to see which one is causing the problem, and then turn it off for good and contact its author for support.

  • HP 8740: Vertical lines, while the scanning & photocopies

    I bought a new HP8740 about three weeks ago and everything worked well until today.

    Now I have black vertical lines down the scan or photocopy.

    First of all, I turned off the printer for 30 seconds and put the plug directly into the wall.  It did not work.

    I turned off - unplugged for 5 minutes - but still has the black lines.

    Can someone please suggest something else I can try.

    Hello @gouldian, thank you very much for your answer.

    The only difference between the analysis of the dumpster and using the ADF is where scanning occurs. Uses of the ADF Strip glass (1 "wide) toward the left side of the pane of glass for analysis. Cleaning if ideally white scanner ADF lid and glass ADF scanner should have solved the problem.

    I suggest you to do a blank copy on ADF, keep the page in front of you and carefully clean the place, you get the line in the band scanner & the white plastic strip.

    If the issue is always I suggest you to clean the ADF mechanism itself. You can watch a video of HP http://hp.care/2bYt7Qu that will help you to do this. The video is made using the Officejet 8600 printer, but it's the same for your printer as well.

    Please let me know what happens. Thank you!

    See you soon
