Colored horizontal lines on new blank tabs?

On random new blank tabs, using FF 7.01, horizontal lines appear, taking the whole screen width and several pixels height. I have seen black lines mostly, but also light blue, gray, brown and orange. I have made a screenshot too. I tried safe mode with addons disabled, the problem still exists.

In Firefox 4 and later [http://kb.mozillazine.org/Safe_mode Safe mode] disables extensions and disables hardware acceleration.
*[http://kb.mozillazine.org/Menu_differences Tools > Options] > Advanced > General > Browsing: "Use hardware acceleration when available"
If disabling hardware acceleration works then check if there is an update available for your graphics display driver.
Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

With multiple tabs open, and selecting a new (blank) tab, RoboForm open new web page in far left tab, not the new (blank) one. How to correct this?

Problem: Firefox Browser Tabs when using RoboForm
When using Tabs in the Firefox browser (with multiple Tabs already open), I (1) click to open a new (blank) tab and then, (2) click on RoboForm to go to a new website. Instead of the new website opening in the newly opened (blank) tab it opens in the first (far left) tab. This only began happening when I installed Firefox 5.0 and RoboForm Desktop v7.3.2 at the same time.
My system: HP Pavilion Media center, Windows Vista Ultimate 64-bit, 8GB RAM, Firefox v5.0, Roboform Desktop v7.3.2

Thanks a lot. The culprit turned out to be Webmail Notifier. Unfortunately, there seems to be some problems on their end that the developer has not yet responded to, but something about the extension is screwing up tab functionality.
Thanks!

I have an iphone 4 and i'm having lot of problems:
_ my back camera is blurred although my front camera is fine and working normally
_ my biggest problem is that the screen is showing colored horizontal lines(as perhaps electrical problems). The phone did fell and I already changed its back and front but everything was normal until these problems appeared suddenly
Please can somebody help me to solve it and tell me what are the reasons?
Thx

you can try turning it off and on again, but i doubt that's gonna work, that sounds like more of a hardware issue. Your best bet may be to contact apple and seek service or replacement

Can not open new blank tab window from file, new tab.In Tools/Options/Tabs ticked open new windo w in new tab?

Can not open new blank tab window from file, new tab.In Tools/Options/Tabs I have ticked open new window in new tab?

The Ask Toolbar is probably causing that in the Firefox 3.6.13 version. Disable that extension or un-install it.

Do you mean the new tab (+) button?
Open the Customize window and set which toolbar items to display.
*"3-bar" Firefox menu button > Customize
*if missing items are in the Customize palette then drag them back from the Customize window on the toolbar
*if you do not see an item on a toolbar and in the Customize palette then click the "Restore Defaults" button to restore the default toolbar setup

Everytime I close a tab a new blank tab opens on its own.

Hi,
I'm using Firefox 6.0.2 and it's a while that I'm facing this problem. Anytime I click the little X to close the tab (sometimes I have to click it 2-3 times) it closes the tab but a new blank tab opens itself. For example when I start with 1 tab, open 3 tabs from that page so I have 4, I want to go to another site and close everything about my first site. Then Firefox gives me the new site + 4 blank tabs that can't be closed.
When I open Firefox it works well but after 10-15 minutes or I don't know maybe 1 hour or so this problem appears.
I did not install any new plugin or extension (maybe updated my existing plugins) .
It's not a virus,malware or anything. I'm using Avast home edition (Free) and it updates itself every day several times. I also scanned my system with tdsskiller (read on a forum that solves the problem, but it didn't).
I'm using firefox for years, but this problem is happening only from a week ago.

do you have any toolbars or extensions installed in windows control panel > software or in firefox addons-manager > extensions, that might cause this behaviour? try running firefox in [[Safe Mode]] (close all other instances of firefox and open the browser while holding the shift key) and see if the problem is persisiting there to diagnose the issue...
''edit: you also have the "Fun Web Products Plugin Stub for 32-bit Windows" plugin installed, that comes bundeled with some toolbars''
from the system details you've submitted it appears that you are using a out of date version of firefox and a out of date version of the java plugin - both are a severe security issue! there were [https://www.mozilla.org/security/known-vulnerabilities/firefox.html dozens of vulnerabilities fixed] since the release of firefox 6. and java versions before 6 update 31 are vulnerable to drive-by-infections (your pc can get infected with malware by simply visiting a website), which are widely exploited in the wild.
i'd recommend that you update both programs as soon as possible: visit getfirefox.com &, java.com; and although you already have a working anti-virus software in place, i'd suggest that you run another full scan of your system with the free anti-malware tool from www.malwarebytes.org in addition (tdsskiller was just a scanner for rootkits).

New windows are like new blank tabs

When I click on a link which opens in a new window, it ends up being like a new blank tab. There's no website of the current page in the address bar, the 'favorite' button is missing, and the 'refresh' doesn't work. The only thing that woks is that it does show the site of the link that I clicked.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

It will not let me open websites, it stays on the new blank tab. It's slow. It always crashes.

I have a mac. At first the browser was really slow and the spinning circle would not go away. I forced quit. When I opened the browser most of my tabs with sites came back except a few although when I clicked on them the showed the web address that was there. So I closed them and tried re-typing and the address but it would not connect, it just stayed on the new blank tab. Firefox has been really slow over the past few months and it keeps crashing.

Please provide a crash id or stacktrace -> https://developer.mozilla.org/en/How_to_get_a_stacktrace_for_a_bug_report

FF 14.0.1: Bookmark with java-script function to build and open URL. Works unless clicked when already in a new blank tab, then does nothing. Why?

On 14.0.1 I have a bookmark which calls a java script function to prompt for input, build and call a dynamic URL. This has worked fine until last update of FF. It works fine if I right click and select Open in a New Tab, or new window. It works fine if I am in any other website and click it. It only does not work, if I open a new blank tab or window, and then click it from inside that new tab. Then it does nothing. Same happens whether the "New tab Page" is displayed or not. Same happens in safe mode.
Bookmark properties:
javascript:void(str=prompt(%22Document%20Number:%22,%22%22));if(str){location.href=%22https://somecompany.com/oip/faces/secure/km/DocumentDisplay.jspx?id=%22+escape(str).split(%22%20%22).join(%22+%22);}

I searched for a recent thread on this but couldn't find it.
This may be the result of a security restriction on some "about" pages such as about:home and about:newtab.
Did you blank the new tab page using the little button or did you actually change the new tab page to about:blank? In case you need steps for testing:
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste '''newtab''' and pause while the list is filtered
(3) Double-click the '''browser.newtab.url''' preference and enter the desired value:
''(i) Page thumbnails (default)''
browser.newtab.url = about:newtab
''(ii) Blank tab''
browser.newtab.url = about:blank
''(iii) Built-in Firefox home page''
browser.newtab.url = about:home
''(iv) Any other page''
browser.newtab.url = full URL to the page

Firefox won't let me click on a tab to open a new blank tab

Whenever i click on the last tab to open a new empty blank tab nothing happens. i downloaded the new firefox that didnt help restarted that didnt help.

Can't you use the [+] button on the Tab bar to open a new Tab? 
Right-click on any Tab and select New Tab? 
Or, you can double-click on a blank spot on the Tab bar, if you don't have many Tabs open.
If something has changed recently and you lost a feature that you once had, you need to do a little troubleshooting. 
Do you have that problem when running in the Firefox SafeMode?

Why doe s "Bing" always appear when I open a new blank tab? I want to stop this. Thanks, please advise.

Have checked history and tabs and add-ons

A new tab opens by default as a blank tab (about:blank).
If that isn't the case then an extension has changed that behavior.

Flickering horizontal lines on new MacBook Pro

I took a ~3 month old MacBook Pro into a store yesterday for some flashing horizontal lines. Upon inspection, the Genius technician told me was from a cracked LCD. I was told the repair is apparently not covered by our AppleCare coverage and could not be a defect, but that it had to be due to an impact coming from the lower right front of the display (above the keyboard). Yet, this is a new machine that doesn't leave my daughter's desk.

Hi
I had something similar about a year ago.
Book a visit to an Apple Store / Genius bar.
My problem was an overheated chip.
Solution new mother board Very expensive.
Good Luck

Horizontal lines on new PowerBook display

Here is my experience with the new PowerBook display/horizontal lines issue. Please post any constructive advice you have that I can try - either to eliminate the problem or to pinpoint the cause more accurately.
I used to own a 15" Powerbook from about 12 months ago, a 1.33GHz model. The display on this was fine. Much better, in terms of brightness and clarity, than my other HP & Dell Windows laptops. When the PowerBook was stolen, one of the main reasons for immediately buying a new replacement PowerBook was the superior display quality.
At the start of November the replacement PowerBook arrived - a 15" hi-res 1.67GHz model. The faint grey horizontal lines covering the whole display were immediately visible. The display is substandard compared to both the previous PowerBook model and my Dell laptop.
Apple Care telephone helpline suggested an NVRAM reset and a PMU reset. Neither of these made any difference.
The PowerBook was then sent back for replacement and a week or so later the new replacement arrived. This also had exactly the same problems.
Apple Care helpline this time said that they could not find any problems with the PowerBook and I should first try the PowerBook connected to an external monitor and secondly take it to an Apple Dealer to show the problem.
I tried it on an external monitor, but unfortunately this is only an old Nokia 15" CRT monitor and though the lines appeared to not be there, the quality of the monitor makes the result inconclusive.
Next up, I will take the PowerBook to the Apple Store. At the same time I have copied "Aqua Blue.bmp" onto my Dell laptop. With the two laptops side by side showing the same image, the defect in the PowerBook display is clearly visible. I hope to be able to take both machines to the Apple Store later this week. I will let the forum know the results...
So, are there any other tips/advice from users as to other tests I can run or other methods to improve the issue?
Many thanks!
It seems obvious, but please don't contravene the Terms of Use for this forum. If you want to complain to Apple, please do it elsewhere - locked posts will get us nowhere

n2o2,
I don't know what let you think that you will eventually receive an AluBook without stripe : Apple Care let you think that ???????.
I have been reading the stripes topics each day since I ordered my new powerbook, late october. I did not see one single post proving that a "free line" 15" powerbook does exist.
The real evidence would come from someone describing the difference between a "non affected" new powerbook sitting besides an affected one, coming from the same PB generation and with exactely the same LCD profile and screen / Colorsync settings.
I did not see a single story like that among the hundred(s) of posts related to horizontal lines.
I have read one post stating that the screen is "crystal clear" and "sharp". The one I received today could be described like that, but it displays those lines, except from the 8 or 10 upper rows of pixels on the menu bar.
The pb15_problems.png file is a very interesting one to me, as it demonstrates that the lines could clearly be attenuated using a single filter without compromising the sharpness/Brightness of the image.
If I compare side by side my 3months old previous generation powerbook and the new one, I must say that (except for the stripes) there is not much difference in daylight in terms of brightness but a perceptible better brightness in the complete darkness.
Well, if someone could prove that some of the new powerbook do not display this "feature", this would certainly push me to return mine. But, seeing how it is difficult to get this organized, I may not want an exchange but a refund, or an upgrade for a 17".
Please tell us quick if you win this battle.

How do I change what I see when I open a new (blank) tab?

I always get "MyStart" by intellibar and I do not want that when I first open a blank tab. How do I go back to what I used to have?

When Firefox 5.0 starts, it automatically adds a new blank tab. How can I stop that?

When I launch Firefax 5.0, a second blank tab automatically launches. How can I stop that from happening, as it reduces visible display area and I then have to close the tab?
