Rendering in Firefox bug

I'm developing a website (Joomla)-. It is still in the test stage, but it can be found on www2.kortrijkserefs.be.

There is a problem in the section of the banner. Sometimes (about 20% of the time) one of the banners is moved to the next line, sometimes the banners appear 2 by 2 (which is the goal). It seems to happen randomly, while the source of the page is the same.

I guess that the same source code would still make the same page, so I think there must be a bug.

Some additional information:

  • All banners are the same size. The images are 480 x 80, Joomla settings are also all set to 480 x 80.
  • It lies with random banners. It is not a banner that is always involved. (I tested which at length.)
  • It seems to happen at random times. It seems simply never occur on the first load of the page. (It's just a feeling, no evidence difficult.)
  • I tried with another browser (a browser with a blue logo e-shaped): no problem, the rendering is perfect.

Hi bdepaepe, I had a quick glance and I think I've experienced the error mean you and solved.

The reason why this happens from time to time, but is not always because the source code is not the same thing every time, as the ads change each update. The error only occurs when two of the < div > tags of class "banneritem" who are on top of each other have a height of 84px each rather than 80px (although even if it's the case the display problem is not always the case).

The reason that some of the 'banneritem' < div > tags have a height of 84px is inside them, there is a <>tag that contains an < img > tag and < a > tag has not been set ' display: block;'. < a > tags are inline by default, so should not be used to hold block level elements such as images, unless that include styles for the < a > tag ' display: block; ".

  • Content of UpdatePanel is not rendered in Firefox 42 after second partial publication

    I changed the values of B and C properly completed. Then I went and changed, the values of B did not update.

  • broadcasting live does not appear, and I think that its connected to the "firefox" bug, please help, new mac user!

    so far, your main problem is flash player, you must include the updates Flash Player with all the updates of firefox, oh and updated player get. It's your bug I 'think '. If it is not part of the territory firefox let me know. However, will not be broadcast live, I asked them, they had little info. including, you update your browser recently - with no answer to this question, so here I am. I don't know if the flashplayer or everything that has nothing to do with live stream or not, BUT quicktime play or help live streaming right? have no idea and the new mac user. GL

    Adobe Systems, Inc. (owner of Adobe Flash) is not related to Mozilla Org in any way. Mozilla has nothing to do with updates to the software they do not create or owned by another company.

    You have a very old version of Flash installed - Shockwave Flash 9.0 r47 - you must upgrade to the latest version available for Mac OSX 10.4.

  • Rendered inDesign error/Bug - not adding vector source causes a slight rendering problem

    Very well; This has bothered me for some time and just recently was able to identify the source of this problem.

    Sometimes, you will notice the same layouts with very small displacements, problems of weight and other adjustments case loosed. I can see these slightly in InDesign views, but it is very spectacular inside a PDF file... I noticed this slight mistake throughout the presentations all the time.

    I was able to recreate the problem and find out the reason. There was a single image, a scan of my signature, placed as a psd, that appears on my front page and not on the second page of my CV. Remove this immediately resolved image rendering problem involving displacements of the hairlines and weight problems, that I had with the cover page. Replaces the psd placed with other images didn't help.

    I replaced the image of the signature with a vector trace and Yahtzee - no bug rendering more. As much as I can say that the problem is with raster images.
    Pages with only the vector components and display of pixelated text data.

    I did not have the opportunity to play with Adobe Creative Cloud, I hope that this is no longer a problem.

    Sounds like well-known transparency rendering effects.

  • Firefox BUG 37: Cookies - "keep until: I close Firefox ' definition of BROKEN

    If you choose to customize the settings of your story and choose "Accept cookies from sites", but only "keep until: closing firefox" you'll find that cookies from http and https sites remain in Firefox after Firefox restarts.

    Please correct this immediately.

    This always works for me.

    Have you tried to delete these cookies.
    'Delete Cookies' sites causing problems:

    • Firefox/tools > Options > privacy > "Use the custom settings for history" > Cookies: "show the Cookies".

    If the deletion of cookies did not help, then it is possible that the cookies.sqlite file that stores the cookies has been corrupted.

    • Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete the other files of cookies as cookies.sqlite - journal in the profile folder of Firefox in the case where the cookies.sqlite file has been corrupted.

    You can use this button to go to the Firefox profile folder currently in use:

  • Firefox bug? McAfee SiteAdvisor 3.7.1 jams at 50% CPU useage

    Firefox 35.0.1
    In certain circumstances, Firefox starts using too much time CPU. It seems to happen when you try to do too many things at once. But, once in this state out of functions (closing all tabs) except my homepage that Firefox is still stuck using 50% of the CPU and more than 200,000 k of memory. The only way out of this should close Firefox and restart.

    After much experimenting, I found that disabling (extension) McAfee SiteAdvisor "cured" the problem. Is there an incompatibility here? Is there one fix other than to disable SiteAdvisor?

    How can I report to the mozilla developers?

    McAfee SiteAdvisor has been blocked by Mozilla several times over the years due to a large memory leak. Although not recently iirc.
    https://addons.Mozilla.org/en-us/Firefox/blocked/
    It doesn't surprise me a bit that McAfee seems to cause problems for you now.

    Overall, this extension simply duplicates the features that are built into Firefox. IMO, it adds nothing to Firefox, beyond a different data source, or even ' bells and whistles ' users to 'wow '.

  • What is the small icon of Firefox "bug" on the right side of the browser next to the menu?

    Menu to the right of the browser is a graphic or icon that appears to be connected to the combustion chamber. This icon is poorly equipped and distracting to the browser and seems to serve no purpose other than just being annoying.

    If it is displayed with the intention of Mozilla, take this comment as a complaint of dissatisfaction of your product, the Firefox browser.

    I have not yet try the Google browser, but if you're the "intuned' to the user experience, maybe it's time to give them a try.

  • Video usually rendered in FireFox on Mac?

    Hi guys,.

    This works in all browsers for me - except FireFox on Mac. The video elements make same.

    Any suggestions?

    Thank you!

    Hi KyLane,

    Firefox on Mac does not load the video because it does not support files mp4 - only formats VGO and webm video. Firefox on Windows is supported mp4 video.

    Edge of Animate CC 2014 will display a warning at the bottom of the Panel stage if your video is not a source file a mp4 and ogv/webm, advise mp4 and at least one of the other formats (ogv or webm) for wider compatibility with browsers.

  • ActionScript loading in Firefox bug problem

    Help, please.

    I'm working on a page at http://localhost/skitterskatter/gerilance/D4D/index4.html

    The page works properly in Internet Explorer on a PC. In Firefox and some mac browsers when you click on a thumbnail, the image does not display (the image is supposed to extend out of the tile at the top right of the screen). After a refresh page often miniature actions work.

    It seems that the image has to be loaded in the cache before it can move. I can't figure out how to make it work. The following actionscript code:

  • I don't want to upgrade to 5.0 until my antivirus plug-n software is compatible. How can I avoid that Firefox bugging me to upgrade every two days?

    The nag screen to get update's coming two everyday when I click on "ask me later". This is not 'later' in my book, it's going to take longer than two words for my av provider update their plug-ins, I bet.

    OK, I know in the grand scheme of things, it is not a big problem but the ffs, same Adobe can get their head round, offering you a choice of way well before you want to be harassed again. And they used to be really demanding!

    A beta version of Avast is available: http://forum.avast.com/index.php?topic=80428.0

    Or, as in the second post in this forum thread "You can also uninstall webrep of your current avast to have compatibility with FF5."

  • Some JPEG files seem to download very well, but are rendered incompletely.

    Some JPEG files seem to be well uploaded by Firefox, but they do not completely. A progressive JPEG will remain very rough and no progressive JPEG will be missing the lower part. Of all the things I tried, I think maybe it's a bug of rendering in Firefox. More precisely:

    • The images are downloaded properly. The page loading stalls not but join immediately. If I click with the right button on the image and click "View image", he appears completely. If I open the media dialogue information Page tab and look at the picture, it appears quite as well. More curiously, if I use the eyedropper color tool and hover where the rest of the image * should * be, it displays the actual image pixels in the raster and also returns the value of the color of the image in pixels, while the main browser window always makes these regions as being transparent. I added a snapshot of the species to this post. Therefore, the problem also doesn't seem to be a problem of CSS/layout of the page (the Page Inspector shows the img block correctly).
    • Clears all data cache and cookies, then by restarting Firefox in safe mode does not make a difference. I even installed a vanilla Firefox to a new virtual machine and had the same problem when opening these pages. Other browsers (tested: Opera, Chrome, IE) do not show the same problem.
    • Reload with forced renewal cache (Ctrl + Shift + R) most often does not change the rendering of the image, but will rarely showing either more or less incomplete than before.
    • I can see the issue going on with two images on two separate pages. I re-encoded them using different software and different settings, but the problem persists, then it doesn't seem to be a problem of corrupted images.
    • I created an example of a toy to try to reproduce the problem: a same page with a different image, created specifically to try to trigger the problem. What I've found, is that the issue is triggered when the JPEG file above a certain minimum size (somewhere between 15 and 40 KB). What seems to be the rendering of the image in the main window stops after the reading of the image up to a certain length. Once again, the image seems well to be loaded into the cache and memory completely as evidenced by the display when you use the view image, or information Page.

    I made three versions of the test page to try to reproduce the problem. Image of the first page is 11KO and always seems to go completely. Images of the second and third page are respectively 102 kB and 107 KB in size and will be usually incompletely. The image on page 2 use the progressive encoding, so the image will end up blurred. The image on page 3 use straight coding, so the image will eventually be rendered with the bottom part missing.

    So far, I'm not sure why only, I encountered this problem on a specific Web site pages. Something must be the trigger, but it doesn't seem to be a problem with the server, the page or images.

    Update: I introduced the site at Browsershots, asking for Firefox 35.0 renderings and a previous version for each of the Windows, Linux and Mac. Unfortunately, the renditions for Mac failed. As for the others, none of the versions pre-35, 0 present the display problem, and it is not present in Firefox on Ubuntu 12.04 LTS 35.0, but appears on Firefox on Windows 2008 R2 35.0.
    Here is the URL of the test pages where you want to check yourself: (darkened circles be transparent)

    http://www.abgase.org/firefox_debug.html (11kB, no problem)
    http://www.abgase.org/firefox_debug2.html (Progressive 102KO)
    http://www.abgase.org/firefox_debug3.html (no progressive 107KO)

    (Do Ctrl + Shift + R repeatedly if the question does not seem to show, to be sure. If by any chance I can get it to render properly, it will fail again after that 2-3 charging at the most.

    I did have a lot of time lately to make studying more. However, since the upgrade to Firefox 36 a few days ago, I can reproduce is no longer the question. This was confirmed during the audit on all my other Windows systems running Firefox: image rendering is usually interrupted when loading pages on Firefox 35.x, but still fine finishes after upgrade to Firefox 36.x.

    This problem can be considered resolved, that the bug seems to have been given to v35 only.

    I couldn't find anything relevant in the changelog of 36 of Firefox, but also found two Bugzilla reports that could have described the same problem, both claim that the problem goes away when you use v34 and/or v36:

    #1125789: image full size is only partially displayed
    #1126707: Firefox 35, MAC and PC image rendering problems

  • After update Ubuntu 12.04, address/search in Firefox 29,0 bar behaves strangely. Clues?

    I see that some users complain their upgrade 29,0 Firefox Mozilla having questions about the address/search bar, but in my case the update 29,0 Firefox itself ran smoothly and flawless until the last Ubuntu 12.04 automatic update triggered by the net. The 'cat/proc/version' returns:
    "Linux version 3.8.0 - 39-generic (buildd@phianna) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3 - 1ubuntu5)) #57 ~ precise1-Ubuntu SMP Wed Apr 1 20:04:50 UTC 2014."
    I'm guessing that the build of 29,0 Firefox itself is not exactly the villain here, hard...
    Clues? Advice? Conclusions?

    Hello again,

    There is a dashboard for this report: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1316250. So I hope that there will be progress in the resolution of this bug.

    A quick fix that worked for me is:
    Firefox in 29: type about: config [Enter] - promise to be careful - in the search type gfx.xrender.enabled bar - make a right click (F12) and toggle to make new fake - exit Firefox - Firefox open.

    Voila.
