Firefox is having problems with certain web sites, but IE is ok

Top of page is present in IE but not in latest Firefox.

Is it a safe assumption that website is your's? 
What difference does it make which browser '''''you''''' use? Isn't your website for client's or potential clients?
That said, I don't have a problem with that web page on Firefox 2.0.0.20, 3.0.19, 3.5.16, 3.6.13, or the 4.0b9 nightly - it looks the same as in IE8 on 32-bit WinXP SP3, with an AMD 64-bit processor.
The problem shown in your screenshot is with your own Firefox installation. It's like all the "styling" is turned off.

What good is a 64-bit browser without 64-bit plugins? 
Adobe still hasn't released a 64-bit version of Flash, although they do have a "preview" version available.

''BTW, Mozilla does have a Windows 64-bit version of the Firefox 4.0 betas that is being tested now, but it is not going to be released in Jan / Feb when Firefox 4.0 is released. It will probably be released later in 2011 with one of the 4.# versions, I suspect right after Adobe has a 64-bit Flash release version.''

TimeMatters Adobe plugin causes problems with certain Web sites

During a recent upgrade of Adobe professional (6.0 to 8.0) on a Windows 2000 TS we discovered that a program called TimeMatters had installed a couple of plugins to IE 6 including an Adobe plugin. The Adobe plugin caused certain Web sites to be inaccessible. Once we removed the TimeMatters Adobe plugin we were able to access the sites we previously could not access.

Good to know. Both useful pieces of knowledge for others if something similar happens to them - Adobe plug-ins not necessarily from Adobe.

2 days ago I started having problems with some web sites that previously worked fine. They still work fine on other browsers. What happened & can you fix it?

On the Times newspaper site I was using December 19 some of the features stopped working. Has Firefox made an update? I tried downloading Firefox 9.0 but the problems persist. At the end of the news articles is a comments section but this no longer displays in Firefox. There is a SuDoku feature in the Puzzles section which is no longer accessible by Firefox.

Safari problems with certain web pages dowloading a page instead of display

on some sites when i click a link to go to or open a page, it downloads the link. this happens with ebay for example where when i click on a link, it downloads ebay.dll instead (i know, weird). and now, ebay.com isnt even opening - i just get a blank page. it happens with .asp pages and .js pages too. everything seems to work fine in firefox. i was also having problems with gmail which would not allow me to click on links and if i typed, it would jump to another field on the screen if i typed a non-alpha character (i know, weird). that seems to be fixed now and i can use gmail.
not sure what the problem is. any ideas?

You would have to remove (uninstall) or reinstall the Georgia font if it is currently corrupted.
You can use the System File Checker to check for missing and corrupted font files.
It needs to be run from an Elevated Command Prompt.
Open a cmd.exe window as Administrator:
Start, click Programs, click Accessories
Right-click Command Prompt, and choose "Run as administrator"
Click past the UAC Screen
After the cmd.exe prompt, type: sfc.exe /scannow and press Enter

Firefox is having problems with google and google calendars

Two things: can't keep two separate google accounts functioning, one being their calendar used by a client to which we have access (client A), and the other a gmail inbox (client B).
The two accounts are unrelated but accessed from the same computer. When trying to refresh after appt setting for client A, google defaults to client B's calendar and logs me out of their gmail account.
Second hassle, incoming messages to the gmail inbox activates the scroll bar and takes me to the bottom of whatever page I am viewing on the net, or if I'm typing an email hangs the machine so I can't use the keyboard or swap between tabs.
I also have trouble with plugins so wonder where the problem lies?

Firefox is having problems with Washington Gas web site connection for online bill payments

when I try to log on to WashGas homepage and/or its login page, a pop up window appears saying that firefox cannot certify authenticity on my connection as if there could be a problem with server connection, fraud ie a third party is trying to log in with my identity and/or other. Please help clarify problem so I may proceed with monthly payments as usual. Thanks

i have a blackberry 9300 3g and i cant seem to be able to download the new device software (os6) since i have os5 in my device already. i have tried downloading using the desktop software but i keep on recieving errors about my internet connection. there is nothing wrong with my internet connection so far. i also recieved a download link from a member of this board as a solution but the link is for OS5 and not the new link OS6. can somebody help provide another solution by way of download link to OS 6 instead of OS 5 or any other solution deemed fit by the one providing the solution.
thanks

On the Washington Post website, when I try to click on an article, I get the message, "Invalid URL". I don't have this problem with other Web sites. I recently upgraded to the secure version of Firefox.

I never had this problem before. I don't know if it's related to now having the secure (HTTPS) version of Firefox. Some WaPo links DO work, but most don't. One other thing: at least once when I Googled "The Washington Post" and clicked on the apparent result, I got a message saying that the certificate was "Not Trusted" and that legitimate Web sites did not ask me to override this issue and proceed to the site. Yet the website I'm trying to use is "www.washingtonpost.com", which I know for a fact is THE Post Website. What's going on, and how can I fix this? Thanks.

Having problems accessing certain web pages online.

I have no problem going to web pages when I bypass the airport extreme. When I connect my G4 notebook to the airport extreme it does not allow me to go to certain web pages.

I'm having the same issue too! I noticed it the night I installed Leopard, so I was thinking it was Mail and Safari 3 acting up. But tonight I unhooked the AEBS and was able to access my site and email just fine.
I've tried resetting the AEBS several times, but it hasn't helped.

Problem with viewing web site- feedback needed

I have a friend who had his site redesigned and integrated with Paypal recently.
He is a Windows user and I am a Mac user.
For some reason I am unable to view the blue Buy Now buttons on his site and if i keep trying long enough the browser will suddenly tell me that the site server cannot be found.
I was told by paypal that it was a cookie problem but i completly cleared out everything and it still does not work.
I have tried both IE and Firefox. IE will work for me sometimes, but once the problem begin happening in Firefox then IE stops working also.
I have also tried using my PC and if i use it before the Mac, i can see it fine but if the Mac starts messing things up i will no longer be able to view it on my PC. I called a friend while having this problem and he said he could see it fine on his PC (not Mac).
I am beginning to think that it is a wireless network problem since i have tried everything else i can think of.
Could some of you please view this page and just let me know if you have any problem seeing the two top Buy Now buttons?
Please also let me know what browsers you used...
The BUY NOW buttons in question should be just below the Download buttons...
Please give me some feedback. This will help me decide if it is a local issue or not.

Thanks, this would be a great help to my diagnosis 8-)

Works fine here in Safari.
I think you have a Router problem, or a Modem with a Broadcom Chipset in it.

Firefox-only connection problems with some SSL sites network-wide

I recently starting experiencing problems with sites not loading in Firefox with the error "Connection was interrupted". I've consistently seen this problem trying to load accounts.google.com. The problem exists in both versions 3.6.26 (OS X 10.4 latest available) and 10.0.1 (Windows XP/7/server2k3). In every single case, other browsers on the same system (Safari, various IE versions) can load the same URLs just fine.
I've already verified no proxy (FF and working browsers, all OSes), disabled ipv6 and preteching in network.dns, disabled all add-ons, deleted existing profiles, cleared cache, and cleared recent history. Existing articles suggest disabling DNS prefetch,

Nope. Settings are default as far as I can tell. Validate a certificate if it specifies an OCSP server is selected, connection-fails-invalid is not checked.
I resolved the issue after talking to my ISP - there was a DNS caching issue and I was getting an invalid IP for ocsp.thawte.com - but the behavior seems buggy. The OCSP server connection WAS failing (with a timeout) and per Fiddler FF just keeps issuing repeat OCSP requests before eventually giving up with the interrupted connection error. The "When an OCSP server connection fails" option doesn't seem to do what it says in this case; prior to getting the DNS issue fixed the only solution was to disable OCSP completely.
Perhaps the problem is that the OCSP connection timed out rather than being refused or unresolvable, but recognizing multiple timeouts as a connection failure might be more user-friendly.

How many of us are having problems with accessing web pages?

For five days I have been having problems accessing web pages, constantly getting the message
Safari can't connect to server etc. etc. It takes me ages just to get to one page without permanently returning to the previous one & trying again. I have tried to use these support pages & find it increasingly difficult to just open a page let alone post anything. If this works I'll be amazed!
I have checked with my ISP - British Telecom. who say there have been a lot of "worms" & 'viruses" across the internet in the last week. Has Safari been contaminated or is it just the www that is the problem? Has anybody at Apple investigated this problem?
I am getting increasingly frustrated by the whole thing as nobody seems to come up with a viable answer. Even if Safari is at fault it would be nice to know where we stand & that somebody is trying to do something about it!

Thanks for that suggestion petitbjs. I think all is OK now. It started without warning, I hadn't changed anything, I just tend to use everything on the computer as it came, I'm a bit chicken to change anything incase I mess it up!!
Starman et al,
I had to phone BT this evening when I found my internet wireless phone wasn't connecting when I dialled out, it was the same yesterday evening but as I was trying to phone my son in Rio & was expecting him to move house at any time, I thought he might have had the phone disconnected, or it was just something wrong their end as I had the dialling tone OK & assumed the phone was fine. I have been using the landline, both of which go through the Home Hub, all through the last week without any problems.
Eventually the BT man had me unplugging the Hub from the mains whilst holding down the Wireless Association button, after which it was OK, however during all this (apart from when it was unplugged, obviously) I still had uninterrrupted internet service as I had to log into the BT website to check the configuration or something, & the chap seemed to think the phone's hub problem would have had nothing to do with my internet problem over the past few days.
Anyway, things seem to be fine now, I'll just hope it stays that way but at least I can try the unplugging trick if I have similar problems in the future.
Once again, thank you all for your help & suggestions, it is a great comfort to me knowing that I have these boards to call on for assistance on virtually any problem I have with my Mac. Before he moved to Rio I could cry "Help" to my son too, hopefully once they move & get set up with an internet connection next week we will be able to video chat (the whole reason I bought the new Mac!).
Many thanks to all,
Carol.

Video play: having problems with certain files.

I am unable to play certain videos on my Macbook.
I have installed flip4mac, and it shows as a plugin on Safari.
I have installed WMV 9.
I have installed JAVA.
I have all current OSX and Quicktime updates installed.
An example of a video that I want to play, from tv station KWTX.COM, looks like this:
javascript:playVideo('1245766',%20'Heart%20Health%2002.15.07',%20'v',%20'Health' ,%20'95167',%20'Health',%20'fvCatNo=&backgroundImageURL=',%20'ww2.KWTX.com');
I'm stumped. I don't know what to try next.
Any help appreciated.

Matthew
I believe this forum is appropriate for your question.
Your symptoms sound like an issue with negotiation of segment size and fragmentation. Path MTU Discovery is generally used in setting up a TCP connection to discover the largest frame that can be sent without requiring fragmentation. However there are things that can prevent PMTUD from working properly. Most especially there are some networks that block the ICMP response of Fragmentation Required but DF Set. So the end stations do not find the optimum frame size. If the end station sends a maximum frame size (as most would) and somewhere along the path the frame needs fragmentation, then the packet will be dropped.
Your symptoms sound like in trying to go to those sites you open the TCP connection, the first several frames are relatively small and succeed, so you see the initial message from the site, but then are sending large frames which get dropped.
One way around this is to configure ip tcp adjust-mss and set a smaller size. I have encountered symptoms like yours, have set the size to something around 1360, and had things work very well. I suggest that you give this a try and let us know if it helps.

I am having problems with certain pages on our churches website. It is the pages where pictures are posted. Any ideas what can cause this?

Our church website has 2 links with pictures. I am not able to click on the link and see them. This is the only site I have a problem with. I have tried to change my settings but nothing seems to help.

Do you ave ad-blocking software or use an extension like Adblock Plus?
If a link has '''ads''' (uplo'''ads''') in the file path then that is the first to check.
