My sincerest apologies if this double posts! The first time I attempted to send, it claimed I didn't have permission to access the page.

Anyway, I've recently upgraded from Firefox 14 (portable) to Firefox 19 (also portable), and noticed that the way Fx19 handles partially loaded images is much different. I don't know if this is a setting (I've looked and found nothing) or if it's a quirk of the browser, but I need the functionality that it used to have in order to properly use the internet with the speed of connection I have. So, I'm hoping someone can help me figure out a way to make Firefox 19 behave as 14 did.

In Fx14, and the way I need it to behave, when I stopped a page that was loading, images froze how they were -- even if they weren't fully loaded. So I'd have a partial piece of some images, a frozen frame on some gifs, but enough to figure out what I was looking at and whether I wanted to right click > reload image to see the full thing or scroll on past and save my bandwidth and time. (Since I view image-heavy sites such as tumblr, this is actually quite necessary for me!)

Now, if I stop a page while it's loading, any images that aren't fully loaded blink out of existence and become empty boxes. This is completely useless to me and very frustrating. But I'd greatly prefer if there's an extension or setting or about:config trick in there somewhere to bring back the old functionality. (To me, it almost seems like it might be a bug, that it's turning so many things into placeholders now.) I'd rather not have to downgrade just to get this important feature back, especially since Firefox 19 runs far more smoothly than Firefox 14 did, but it's something that I can't do without due to how I browse the internet.

Before I changed internet service providers, I could type my search queries into the url bar and receive search results from Google. After I switched ISPs, my queries typed into the url bar are put into my new ISP's horrible search engine. How do I change it back?

I've already tried going to about:config and changing the value of the keyword.URL preference to "http://www.google.com/search?ie=UTF-8&oe=UTF-8&q=" but that didn't fix my problem.

New information since creation of the post:

My ISP is Optimum. I have opted out of DNS Assistance and still have seen no change.

When my search term is two words or more, I am directed to Google search results. If my search term is only one word, however, I am still directed to Optimum's search results.

In newer versions of FF the bookmarks toolbar is off by default, as described here: https://support.mozilla.org/en-US/kb/customize-firefox-controls-buttons-and-toolbars?esab=a&as=aaq

I know how to re-enable it manually, which I have to do every single time I start FF. How can I change the default to "on"?

The c-suckers here have blocked access to download page for firefox. every link on the mozilla.org pages just takes you back to the blocked download page. Is there a trusted ftp site where I can download the current version? I've even tried to download the beta version. the installer loads an runs, but the connection is always reset.

I have a number of documents I want to embed in webpages for easy access. These are PDFs generated with pdftex locally under MikTeX. They use Adobe Minion Pro font. They render flawlessly in Adobe Reader, Sumatra, PDFXchange, and in Chrome (with its built-in viewer). They are also fine in APV PDF Viewer (MuPDF library) and PDF to GO (Documents to Go) on Android . . . you get the idea. But in Firefox they render interspersed with random characters. Example pdf and screen captures available (I don't see a way to post them).

In the meantime I've replaced the PDF.js with the Adobe Plug-in which fixes the issue for me. I'm concerned about others who may visit the site with Firefox as the default setting leaves these documents all but unreadable. Must I alter them to use a different font in order to preserve compatibility with pdf.js? Minion is widely distributed and well regarded (and not cheap) it would require significant adjustment to the formatting as well . . . Please advise.

I used to be able to choose from all folders when bookmarking a site. I was able to click on 'Choose' and all folder would drop down. After a firefox update yesterday, only 5 folders show up, along with the 'Choose' option. When I click on 'Choose' it takes me to to 'UnSorted Bookmarks'. Has this happened to anyone else and how do I get out of this?

Firefox used to delete history just fine, before the recent update. I have my history settings to "never remember history" and clear my history after signing out of any website. Firefox also used to log me out of all sites with the click of the "clear all history" button, but it now remains signed in. This is really annoying and troublesome and a waste of time for me to always have to sign in and out of every one of my accounts. I also cleared my history and still have youtube videos in the "recommended for you" section after I signed out and cleared my history, meaning it didn't actually clear it. When I open the "history" tab, it does not show any history.

I just got notice this morning about this new version of Firefox but I'm hesitant to install until I know that my Norton toolbar will work. Can you provide some information? Thanks!

Recently parts of the text but not all the text on a webpage has started to blur or distort. Sometimes this distortion moves to the right. If i hover my mouse over the distortion or scroll the page it disappears. This is especially annoying on Facebook ect. I have not noticed this problem in IE or Chome but i havn't used either for prolonged periods to be honest. It's hard to test what causes it because the problem is intermittent, Facebook is affected the worst but have had this problem on other websites including this form and even in the Addon menu.

I have tried, running in safe mode, disabling plugins and clearing the cache none of which have solved the problem.

here's a screenshot of the distortion: http://img5.imageshack.us/img5/2128/facebookblur.png

This has happened three times in the past two months, twice when I was opening a new tab and once when I was refreshing a tab. Firefox freezes (spinning wheel), and won't force quit when I try from the dock or from the Force Quit menu or the Activity Monitor, and it will actually freeze the Force Quit Menu and Activity Monitor as well, as well as any other program I try to quit or force quit at the time. I tried to open Terminal to kill the process, but although it's able to open up, it wouldn't give me the command line.

To clarify: I can open other programs during this time but they vary in responsiveness. I played around the third time this happened; I wanted to see if I could wait it out, because Firefox did automatically quit after two minutes or so the second time this happened, but no such luck the first or third time. I ended up having to force shut down (shut down by menu would not work).

The message "Additional plugins are required to display all the media on this page" occurs on every page of every web site. Click Install and I get message "No suitable plugins were found". V 19.0.2 Windows 8

I wonder if anyone knows the way to roll back from an update in Firefox? I do not wish to remove and re-install if it's possible just to roll back. I am using Windows 7 Pro and the "about Firefox" says I have 19.0 installed. The update causing the problem went in on 19/03/2013. Hope someone can help. Regards. G

When I watch a video with Mozilla Firefox on sites like YouTube, Google Video or Bing Video in full screen the taskbar shows at the bottom of my screen and doesn't disappear like it does in Internet Explorer. How do I watch videos in full screen without the taskbar showing? It's not a website problem, it's not a Windows problem, it only does this on Mozilla Firefox's browser. All three websites play perfect full screen video on the Internet Explorer browser with no taskbar showing at the bottom..

Update history says version 20.0.1 was installed on April 11, but Help About Firefox says I have version 19.0.2. Since I'm on the release channel, with updates automatic, I should be current.

Thank you, Pete Reque

While trying to track down which Add-On is hammering my CPU, I found another odd behaviour while trying to disable plug-ins one-by-one: With certain plug-ins (specifically Flash, Foxit Reader, and Silverlight), the next time I restart Firefox, they are enabled again. After disabling them a few times, they finally stay disabled on restart, but then I can't re-enable them. (Same thing happens, but in reverse; I enable them, but they return to disabled on restart.)

At one point I was trying to disable Foxit and Silverlight and re-enable Flash. Each time I restarted, Foxit and Silverlight would be enabled again and Flash disabled again. After about five or six attempts over two days, suddenly it worked.

Has anyone else noticed this behaviour? I don't recall ever having problems disabling unwanted plugins before.

Note: This is about plug-ins, not extensions. And this isn't about permanently disabling or removing plugins.

Sorry folks, I have asked the writer but just want to keep options open.

"Net usage item 1.2.337.1" It used to work. Now it constantly just gives a red circle with a white cross in it.

But, if I RMB in it, and "visit ISP usage page" it works.

So if it opens the link and can show me on a page, SOMETHING has changed, but where? Anyone else have this error?

P.S. My ISP is bigpond.

I am Firefox user since its verson2.

I am using windows 7, Firefox was working correctly but few days back when my system engineer installed Symantec end point protection and domain. My Firefox start freezing very frequently (It is not crashing). But it is too irritating to work now.

I want to use same in future. Please help me to resolve the same.

When in Yahoo mail, the OPEN WEB LOCATION box opens for each letter I try to type in in the "To" line and/or the "Subject" line of any new e-mail to someone. I type a letter, the Box opens, and I cannot type anything in the e-mail window anywhere until I close the box. I close the box, type another letter, and the OWL Box open gain. It takes forever to type anything. This started when I updated Firefox to the new 21 version. I Uninstalled and reinstalled Firefox. No help. I uninstalled 21 and re-installed 19 (I was using 19 with no problems until today). No help. The problem will not go away. I note that others have complained of this problem. Is there a fix yet? I have been forced back to IE in the meantime.
