Firefox Support Forum

I am running an old computer using XP. All I want to do on this computer is view Virtual Railfan live streaming videos. When I try to view a video, it says that my browser doesn't recognize any of the video formats available. Then it points me to a html5 faq. When I click on that I go to Firefox home page and it wants me to download Firefox. I already have downloaded the latest Firefox. Is there a workaround for this?

Hi, I had Firefox on my Thinkpad T60 and it worked. I hadn't used the laptop for sometime but now Firefox didn't work, neither did iexplore or slimbrowser, they all produce the same error. I was able to find an earlier version of Forefox and it works fine but slow. Strangely when I go to goole or slimbrowser those site are found but will not find anything like amazon.com, the message from the File/properties: unknown protocal, size,connection not encrypted, address (URL): res://C:\WINDOWS\system32\shdoclc.dll/dnserror.htm#http://www.amazon.com/?_encoding=UTF8&camp=1789&creative=9325&linkCode=ur2&tag=flashpcom-20&sbSource=linksbar

The event viewer has this message: source cryp32: Failed extract of third-party root list from auto update cab at: <http://www.download.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootstl.cab> with error: Unknown cryptographic algorithm.

This laptop is 32 bit, Windows XP.

Thank you for your help....would like to update to new firefox browser.

Sometimes my wifi connection is choppy (darn that microwave popcorn!) and I hate it when I'm in the middle of reading the links in Drudge and it reloads....sometimes shifting the layout a bit or just hanging while it waits for some adserver to respond.

Is there any way to stop this from happening? Tried Freezing the tab. And for some reason, firefox is not preventing this page from automatically reloading like it does others.

Any ideas?

We've a new software which always opens a pop-up window when clicking on the Java links. The content of such a re-sizable window perfectly fits into a new tab. I'd like to force those new windows into a new tab. Pop-up blocker is active and that internal site is in the exception list. So it would be nice to have an option field for that in the general settings or in the Pop-up blocker settings. This is no bug, but could be a new feature of Firefox (like in IE). Thanks &

Kind regards, Peter Marbler

I have the latest version of Firefox running under Win 10. There is no option to allow adobe flash to run on some websites like many faq's imply. I am prompted everytime I go to the vector vest url for the daily color guard report. This problem for me started a month or more ago. How do I set firefox to stop prompting me to allow adobe flash to run permanently.

I use cryptographic module PKCS#11 to browse some sites. I load corresponding xxx.dll file : Options>advanced>Certificates>SecurityDevices>Load . The PKCS#11 device appears in the Device Manager list of devices. I can Log in this PKCS#11 reader and view data. "OK", View Certificates - I view this certificate. "OK" and quit Options menu. If I close the FF browser, these settings was lost and I have to install them manually again. How to save these settings ?

Hi Everybody, im Dr Nick. Firefox 52 is my love. i have tried younger models. but i always come back too ole faithful.

Shes got all the right shapes. sizes. and feels. but these days speed is lacking. despite my upgrading both my core2 duos. too a core2quad. and a hex core xeon. both 12gb ram They both run quite fast, but much slower than they used too. infact, they are slower than the firefox, on my pentium 3,4, and HT AND my core2duo / 4gb laptop. with the latest firefox ? wtf.

I am being throttled i tell you !!!. i have slimmed her down, and run only add blocker, and crypto mining blocker.

But its not youtube that is so slow... its everything, the whole firefox browser. [ this is the bit that bugs me ]. i run comprehensive firewall ] and not even alex jones can explain who is doing this.

is anyone doing any research too this end ?. or have any russian software too prevent it ?.

GODSPEED Mozilla !!

Adobe in Firefox application has worked for me for years, until a day or two ago. I can download the PDF file, but when opening I only see the image a second or two, then get a "Application has generated an exemption that could not be handled " message. Cannot print once error message drops in. Do i need to uncheck the use Adobe in Firefox option and use Adobe directly? I know my XP is very dated, but Windows 7 and on will not accommodate a program I use daily.

My computer is to old to upgrade. I am running firefox 52.9. Most of the time I keep getting not responding errors. I have to shut down firefox and restart computer. Sometime this works and sometimes it doesn't help.

My other computer uses Win7 and every time Firefox updates, I loose LastPass and AdBlock+. I have to open 'add-ons', click 'disable', then click 'enable' and close and reopen Firefox. today I open Firefox, it tells me all about the wonderfulness of version 67, but the add-ons are marked as 'Legacy'. When I click to get more info, it shows nothing and I have to click 'extensions' again. If I click 'disable' and close the browser, the next time it shows a button to 'enable'. But clicking and restarting the browser does no good. I tried to get help, but without LastPass, which Mozilla recommends, I can't even ask the questions.

I am running Firefox 52.9.0 (32-bit), Win XP PRO SP3 on several computers and only my desktop has this problem.

Youtube videos embedded in other pages do not work and only blank space is displayed but if I go to Youtube the videos play correctly. This only happens in one computer. In other computers running same Firefox 52.9.0 (32-bit), Win XP PRO SP3 this problem does not happen.

I guess it might be some configuration problem.

Hi, Since the add on problems, i've been trying to dowload the fix for firefox version 52.9.0 (xp32bit) How ever what ever i try, i get a message "unable to dowload due to connection failure" and tried everything, even re-installing firefox, still the same. Is there a way to dowload the fix, save in and run it as a file ? It is pretty annoying as i can't add any add ons and don't know what to do if i can't even download the fix from the website. Any help would be appreciated.

Thanks, Phil.
