Firefox loads very slowly, other browsers run fine

Firefox has been loading webpages very slowly, whereas any other browser I use will load them much faster. I can even start loading a page in Firefox, open a different browser, load the same web page, see that it gets fully loaded in the second browser, close that browser, and swtich back to Firefox, and Firefox will not have the page visibly loaded yet. It is for this reason that I know the problem is not with my internet connection.
I use Firefox on my Windows 8 computer with no problems - it is actually one of the fastest browsers that I've used; I'm having a problem with it on a Windows 7 computer. I've tried several other fixes I've found on this site - disabling add-ons, starting Firefox in safe mode, clearing the cache, and enabling hardware acceleration. None of these have helped speed up Firefox. I'm no sure what else I could do at this point.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to install for Firefox and the plugin-container process and the updater process.

Create a new profile as a test to check if your current profile is causing the problem.

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

Firefox updated yesterday and now it won't load any webpages. Have reviewed articles on this problem and checked everything. Still won't load. All other browsers work fine.

Have checked firewall and network settings and compared to other computers running firefox. All is ok, but firefox won't load any webpages. This started immediately after it updated yesterday. No error messages.
Have been having problems with updates on serveral of our computers for a month or so. Previous problems have always been that firefox renames a file it needs by adding moz.backup to the file name and I have to search for the file and remove it. This time I'm getting no error messages.

Firefox cannot load pages that other browsers can, but the 'help' page for this issue did not fix the problem.

I am troubleshooting an issue occurring on a family member's pc. Immediately after changing their "search" settings from "Yahoo search" to "Google search", they found that Firefox was unable to load any webpages. After troubleshooting the problem, I found the "Firefox can't load websites but other browsers can" help page, and attempted each of the solutions listed. None of those solutions fixed the issue. Also, I uninstalled and re-installed Firefox; the issue persists. However, the 'new' version of Firefox remembered the tabs left open when the 'old' version was deleted, so some temporary files likely persisted.
Are there any other steps that can be taken, or is Firefox on this computer no longer an option?

Start with this;
Type '''about:preferences#advanced'''<Enter> in the address bar.
Under '''Advanced,''' Select '''Network.'''
Look for '''Configure How Firefox Connects''' and press the '''Settings''' button.
Check the settings.
Some problems occurs when your Internet security program was set
to trust the previous version of Firefox, but no longer recognizes your
updated version as trusted. Now how to fix the problem: To allow
Firefox to connect to the Internet again;
* Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
* Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see
'''[https://support.mozilla.org/en-US/kb/configure-firewalls-so-firefox-can-access-internet Configure firewalls so that Firefox can access the Internet.]''' {web link}
If there is still a problem, go to that computer and do this;
Type '''about:support''' in the address bar and press '''Enter.'''
Under the main banner, press the button; '''Copy Text To Clipboard.'''.
Then in the reply box at the bottom of this page,
do a right click in the box and select '''Paste.'''
This will show us your system details.

On CNET Downloads the Search Box won't autocomplete. This worked in versions prior to Firefox 4. Other browsers work fine. Any ideas?

If you go to the affected site and try to search (upper right hand corner of site) you will have "Suggested searches" popping up. However, with Firefox 4 and newer you are not able to select any of the possibilities. This worked fine with earlier versions of Firefox and works with other browsers. I've seen this problem elsewhere as well but can't remember the web sites. Hope you can fix it with CNET! Thank you.

Hello,
I had the same problem, i found a solution :
You have to delete the file named chromeappsstore.sqlite, which is located in C:\Users\XXXX\AppData\Roaming\Mozilla\Firefox\Profiles\xxxxxxxx.default
(where XXXX is your User name and xxxxxxxx.default is your profile name)
Then restart Firefox, it should recreate the file, and it should be working good now.
Note : Before deleting it, just rename it or make a backup, and make sure everything is working.
Hope this helps !

Iweb 09 pages load very slowly - How can I fix this?

Hi-
Just published my website to ipage.com and every page is loading very slowly despite the fact that the backgrounds and graphics are very simple (Many of the pages are text only). I'm using the "Modern theme" Blank with a gradient fill, which is what seems to be causing the slowdown. I've tried it on two computers (macbook and macbook pro), two browsers (safari and firefox) and my iphone 4 - performance is equally poor on all three. Spoke to my Web Hosting technical support (I'm using Ipage) and he says my site is only using 17 mb, which should not cause any issues. My download speeds are also very fast so it's not my computers that are causing the issue (Between 20.5 and 23.2 mbps, ping=18ms). The site address is www.jeffreyjanger.com.
Thanks,
jeff

Bonjour
the slowness is explained by the big size of gradient fill image. Your background [image|http://www.jeffreyjanger.com/JeffreyJanger/Home_files/backgroundimage_11.png] is a PNG
You've changed color opacity, that forces iWeb to create a PNG file.
if you let opacity to 100%, iWeb will create a JPEG file
In an iWeb published site, JPEG file size can be 25% smaller than PNG (and sometimes more...)

The fancybox images on the Recent Images section of the site are loading very slowly. This just started happening with Mozilla 8. Is there a fix?

The images on the fancybox on the bottom of our main page (Recent Images) are loading very slowly. This issue is only on Mozilla 8. When you browse through the images the loading begins from top to bottom.

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.
Try to decrease the value of the pref network.http.max-connections from 256 to 30 as used in Firefox 3 versions.

Since update, various sites load very slowly and some do not load until "Reload Current Page" is clicked several times.

Since Firefox update (6.0.2) many sites load very slowly and some do not load at all (green circle rotates infinitely) until "Reload Current Page" is clicked on 2 to 12 times.
Returned to version 5. No more slow load.
Automatically re-updated me to 6.0.2 and now slow again.
Returned to FF 5 again and turned off automatic update.
Downloaded 7.0.1 and the problem seems to be solved.

Same here, only that updating to 7.0 or 7.0.1 doesn't seem to solve this issue. Seems to have something to do with loading images (e.g: adobe.com stops loading when "wwwimages.adobe.com" is being loaded. imdb.com, on the other hand, seems to load images very slowly and not all of them).
Safe-mode. disabling add-ons, clearing cache and cookies and checking for malware doesn't help.

Why when I open multiple tabs in Facebook, the tabs load very slowly and most times don't load at all?

How do you stop 'Transferring Data from...' in toolbar on first page of a website - eventually stops but takes a minute then loases some images on a site when complete - other browsers are fine.

Only happens on index page of website - Firefox repeatedly says 'connecting to site/transfering data from site in the status bar for about a minute before finally 'done', then some images on the index page are missing. All other browsers are fine - how do you turn off this problem in Firefox - there is nothing to download on the index page, already displayed but can't continue unless you jump to another page in the site. Searched web and many references to this but no definate answer. Code is same on all pages of site, just the index page which hangs.

You can check for recently installed suspicious or unknown extensions.

Named destination not working in Firefox 3.6.3, other browsers are ok

I've added several named destinations to a PDF. Links to the named destinations within the PDF are working correctly in IE8, Safari and Chrome, but not Firefox 3.6.3. (PC/Windows 7)
With Firefox all the links to named destinations take you to the first page of the PDF instead of to the named destination within the PDF. I've tried changing the format of the links (a href="http://www.anysite.com/mypdf.pdf#location1") instead of (a href="http://www.anysite.com/mypdf.pdf#nameddest=location1"). No success with Firefox. Other browsers are fine.
I'd be interested if anyone else has had a similar issue and whether there are any successful workarounds/solutions.
Thanks a bunch.

The PDF contaning the named destinations was created with Acrobat 9.3.2 Professional.
Since the links to the named destinations are working fine with IE, Chrome and Safari, I'd tend to think this is a Firefox issue, but welcome other ideas.

IBooks Author: in exported file, one page loads very slowly...

iBooks Author: in exported file, one page loads very slowly and drags when scrolling through pages, almost stopping the scroll. I have never seen this problem before with photo pages. Normally they scroll just as smoothly as text pages.
I have tried rebuilding the page with more compressed files to no avail. The image files used on the page are not any bigger than others I have used previously without any problem.
I have tried restarting my iBook.
I am using a template that I have modified quite a bit. The templates currently offered by Apple and third parties are not even close to what I am looking for in terms of layout, so I have to rip almost everything out of the page and start with a blank page, most of the time. I tried modyfying the layouts to save time and then saved as a new template. Apple really needs to add a module to create your own template at the beginning of a project. Or they need to create one very open template, without much on the pages.

I finally solved the problem by using an unmodified template. I would still like to know how my modifications to the other template caused the problem, but for now it remains a mystery. Thanks for your ideas.
Next I will try modifying the template without saving it as a template (merely saving it as a file) to see if I can get away with my modifications. Also I will make fewer modifications.
Slowly but surely I am learning this program by trial and error. Each time I try a few formatting variations, output an iBooks file, and open it on my iPad. I have probably done 20 of these tests, so far. Once I work out every detail of the design and structure, I will build the final book. I am lucky to have a beautiful PDF of the hardcover version, generously provided by my publisher. This not only sets a high bar for me, but also allows me to use some of their design elements via screen capture.
iBooks Author has great potential, but I along way to go to get there. One feature I would really like to see in the next update: the ability to add a hidden caption to a photo. The reader would tap the image and the caption would appear. Tap again and it disappears.

Web pages loading very slowly.

It doesn't matter if my Mac is connected with an ethernet cable or wireless, web pages are loading very slowly. I'm sure there's an easy fix for this but I'm clueless. Can anyone offer a suggestion? Thanks...

Try clicking safari> reset safari.this should speed things up a bit. also click preferences, cookies, and clear some unwanted cookies.

Movies on itunes will not load or load very slowly and freeze on my apple tv.

Movies on itunes will not load or load very slowly and freeze on my apple tv. both the computer and apple tv are wired connections on my home network. Checked the network speed and it is between 0 and 1 ms response. This problem just started last week. Only new software introduced recently was update to Norton 360.
Thanks

I know very little about windows but security software is notorious for causing the type of problem you have, you may want to contact Symentec and ask them which settings you need to change.

Website loads very slowly in Safari....

I have had my website for quite a while and all of a sudden, when I try to view it in Safari, it loads very slowly and each time the welcome page loads, there are pictures missing. I have not done anything different to my site. Is this a problem with Mobileme or iWeb or both?? My site is captured4u.com
Thanks

I can't speak for past performance, but any page that is over a MB in size does take longer to load. A problem with your page is that you have an idea of how to add pictures and make the layout how you want it to look, but there is a price the viewer has to pay to download all of those graphics, including some of the text that are being converted to graphics by iWeb (which means Google can't read some of your categories for their index).
I don't find that iWeb does a very good job of optimizing graphics for the web. They work, but dedicated graphics programs like Photoshop or even Photoshop Elements will do much better when the files are resized and saved for web properly.
You would probably do better to simplify the home page with larger single graphics for each category that are used to point to other pages with more related photo's and descriptions. Remember, even the fancy picture frame outlines are more graphics the viewer has to load, and you need to be aware of when iWeb is going to convert your text into graphics either because you are not using standard web safe fonts, are rotating the text or adding other fancy attributes.
Design and optimization are always a compromise. iWeb is not always smart about optimization, and mobileme is not the best solution for speed. They're fairly easy to use, but go easy on them...
