Firefox Support Forum

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.

I am running Windows 7, but I am being told by Mozilla that I cannot Update FireFox because XP & Vista area No longer being Supported  ! If my Operating System is Windows 7, Why does Mozilla think I am Running XP or Vista ?

after you had that mess with the addons and the missed certificate you made an update

an AGAIN TABS are ON TOP!!!

WHY!?!?!?!?!?!?

why dont you finally recognize that the user wants to decide tabs on top or tabs on bottom himself?!?!?

i have xp here, firefox 59 something and without giving me a notice my tabs are now on top and no way to get them down again

please find a solution for that and please respect users wishes for tabs on bottom

i dont like tabs on top it is not logic, not convienient and i do not care if you think the other is better. if you think that you are free to use it. please let me and millions of users with tabs on bottom go their way

All of a sudden, I get a message that one or more installed add-ons can't be verified & has been disabled. However, they seem to still work. But I get the message shown below every time I launch Firefox. This just started happening last week.

I've shown a picture of some of the "disabled" add-ons. However, I know for sure that Roboform is still working.

How can I get rid of these messages? Thank you in advance!

For many weeks now a weird block has been placed on my computer, initially followed by "Microsoft technicians" with Indian accents calling up and offering to "help," for a fee. I managed to find a way around this block, but today they have "upped the ante" and I can't get around it. Can you help or tell me where to go for help? I suspect this is beyond Comcast help.

Within the Login security option I composed 23 websites with my user ID and password. Whenever I navigate to a website whose URL is within the Login tool, to my surprise no autofill action occurs. I've used other password tools including Roboform that does autofill as its main function and expected the same from the Firefox password tool. Hence my query on whether there is some action I need to take to launch the autofill functionality. Thanks in advance for any advice.

I'm using Windows XP. All of the desktop shortcuts I make have the Firefox icon. Is there any way to create desktop shortcuts that show the specific icon associated with the web page?

I have been running XP Pro on 2 old Dells since 2005 linked by the Synergy Pro programme and using the Firefox browser.

For some time now there has been no video functionality on the host machine and only occasional functionality on the client machine.

Both machines have Shockwave Flash, which I have uninstalled/re-installed several times with no effect, and OpenH264 (see attached screenshots for details). I also have YouTube™ Flash HTML extension which is active. YouTube check suggests that these are operative, but if I try to view a video I just get a black screen with the error message that the browser does not support any of the available formats.

Does anyone know what the "about:config" settings should be?

Trying to open a website on Firefox and I get this error message...uncaught exception: WebAssembly support is not detected in this browser. Have no idea how to resolve this issue. Is there someone who can assist me with making this correction?

I like to test my web pages as much as possible at home before uploading to a server. I do this by setting up empty drive partitions for my various sites, so that 'root level" access will work similarly on a server or from the hard drive. So, for example, a line on a page like...

<script src="/scripts/siteScripts2.js"> </script>

or

<link rel="stylesheet" type = "text/css" href="/styles/fonts/fonts.css"> <link rel="stylesheet" type = "text/css" href="/styles/spcPageStyles1.css" >

Will reference the files from the root level, as if it was on a server.This works all the time with Chrome and IE, even back to IE-8. So Mozilla Firefox must be blocking file references from local hard Drive root level. If there is a config variable or two I can set to allow it from firefox, I'd appreciate knowing about it. I'm satisfied testing with Chrome and IE, but FF is an important browser to test with.

Thanks in advance!

I'm using Firefox 52.9.0 running on Windows XP, which is no longer supported. I'm finally coming out of the dark ages and I'm buying a new computer running Windows 10. I'll be installing the latest release of Firefox and am unsure if there are compatibility issues to consider. Can I just use backup and restore to migrate the existing profile to the new computer? Thanks for any advice ...
