I don't know what causes this. I've disabled the flash player, and that solved the problem for a bit, but it's now scrolling up and down without my control. It's irritating as I can't read the pages for the scrolling.

I am running my PC with Windows XP pro SP3 (32 bit), and would like to continue doing so as long as I have a browser which can access internet for me. ie is no longer supported for internet access, and support for chrome seems to be disappearing shortly, so I have moved to Firefox. I was pleased to see you still maintain support for XP - how long might I expect to have support for my system using Firefox?

I have an embedded mp4 video background on my site. It functions properly in every browser other than Firefox.

It's not content on a page, so I can't put multiple versions in and have the browser pick.

I also can not use YouTube video as a background video -- nor am I willing to use Flash [since this requires plug-ins to work, and most people are afraid of having Flash on their systems].

Is there any solution, or will this just not work for anyone using Firefox?

Thanks.

I have been using Firefox for years and have had no issue. Tonight, when I try to go to my normal websites (AOL mail, Etsy, etc.) I receive an error message of:

This Connection is Untrusted

You have asked Firefox to connect securely to my.screenname.aol.com, but we can't confirm that your connection is secure.

Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.

What Should I Do?

If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.

my.screenname.aol.com uses an invalid security certificate.

The certificate is not trusted because it was signed using a signature algorithm that was disabled because that algorithm is not secure.

(Error code: sec_error_cert_signature_algorithm_disabled)

I have tried updating Firefox, I have run a security check, I have search the forums...I have not found a solution for this error code.

What am I able to do?

So with the FF 43 update Mozilla is again destroying my work flow. When browsing i I mostly go off of muscle memory. And the new update through up in the top most position of the url drop down the search with option. I disabled that inside of 5 minutes but now instead of that is gives me "Visit "what ever url i may be partially typing" . I'd like this new item disabled and can't seem to find an option for it.

I've never understood why the url bar got enabled for web search when there is already a dedicated search bar.

The add on, Kasperky 4.6.2.23.1 has been disabled but has been working fine until last week. I cannot believe that Kaspersky has gone through the process that Mozilla require or shouldn't they recognise established companies such as Kaspersky.

After one of latest firefox upgrades it started asking me about default browser. The check box "Always check if ... " is not clickable and browser.shell.checkDefaultBrowser is locked. So I want to unlock in order to get rid of startup question. Unfortunately there are instructions in support forums how to enable locking but not how to disable. I tried to substitute mozilla.cfg with blank file - did not help. What else ?

Hi I'm Using Java Developer Kit 8 Update 66 And Java Runtime Environment 8 Update 66 On My Windows 10 x64 Computer.

My Installed Firefox Version Is 43.0.4 x64...

I Can't Use Java. How Can I Use Java?

I found a solution to my problem, but I just wanted to make the problem/solution available to all FireFox users ... Doing "Microsoft Print to PDF" I was getting "a error occurred while printing". This error also occurred trying to do "Microsoft XPS Document Writer". Using "Process Monitor" (from Sysinternals) found "access denied" entry. This occurred even though I had total security access and ownership too. I had been using a non-default "tmp" user environment variable. I set "tmp" back to the default and the problem went away. The problem was not occurring in the other browsers IE, Edge, or Chrome. Also, reinstalling FireFox did not solve the problem since the "tmp" variable was not affected by the reinstall.

Dear Community,

Thanking you in advance for taking the time to read my question.

I have a profile backup of Firefox, which is dated 2016. It is called Old Firefox Data. I have a copy of it on a USB stick. Can any of you please tell me how I could restore this, please? I have read articles about this in the support pages, but they tell me about changing the name of the profle, and its location. This is confusing.

Please can you tell me how I could restore this old backup? Yours MAREK_WES

How can I unlock it? Ubuntu. Thanks

I have a number of HP iLO connections within my corporate network which I use FF to access so that I can control my servers. These are all HTTPS connections and firmware-based and since the servers are now around 5 years old, HP no longer is releasing updates for the iLO.

For most of the iLO connections I'm getting the following error in FF:

Secure Connection Failed

An error occurred during a connection to bkp4.systems.aims.my. SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message. (Error code: ssl_error_weak_server_ephemeral_dh_key)

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

I then have to open up IE to get to the site to do my work and this is very frustrating that I cannot bypass this bug.

I also have supplier portals which we use for our backups and other stuff and I get the same error there and have to use IE to get into those sites.

Is there a fix to this problem or do I have to ditch FF for IE just to get my daily work done??

I used to have a drop down for previously closed tabs now I don't! I am talking about when you accidentally close a tab and then want it back. Can't do that anymore. WHY?

I know where the Firefox map is (C:\Users\MyName\AppData\Roaming\Mozilla\Firefox\Profiles\e8sn4xgq.default) - here I find a map Bookmarkbackups but I cannot find the actual Bookmarks. My problem is that I have all my data on a seperate partition. I now and then make images of my C partition and sometimes need to return to an earlier image. I just now discovered that I loose all Firefox Bookmark changes when I do that.

I also know how to export the bookmarks to an html file an my D partition. But I need to remember doing that regularly.

With Internet Explorer it is possible to change the location of the bookmarks. Whenever I return to an earlier image of my C partition my Favourites stay unchanged on D Couldn't this be done with Firefox?

On Firefox 42, Flash was working properly but after updating to 43.0 some websites give me an error that the Flash plugin failed to load. For example the following site: http://www.roosterteeth.com/episode/rwby-season-3-volume-3-chapter-6-fall

Also, when I go to this adobe site, the Flash video that plays only if Flash is working doesn't play https://www.adobe.com/software/flash/about/

I tried going to the above Adobe site on my other computer which still had Firefox 42.0 and it loaded the video properly but upon updating to 43.0, the video stopped loading on my other computer as well.

I've tried to fix the problem by doing the following with no success: 1. Restarted Firefox 2. Uninstalled and reinstalled Flash 3. Restarted Windows 4. In the list of Firefox plugins at about:addons I made sure that Shockwave Flash was set to "Always Activate" 5. Deleted the Firefox cache and restarted Firefox

I'm using Windows 10 64-bit

I have done EVERYTHING as instructed. Nothing works! Windows Vista Home Premium 32 bit.

All previous versions have been uninstalled. Downloaded via ADOBE DIRECT LINK. No RUN box appears. Nothing happens.

I updated to the newest 44 version. It sent my browser to default with tabs on top. I did a system restore to roll it back to have my toolbars and tabs just like I want them-not what firefox wants. Tell me how to get my tabs back on bottom again.

For this web site: http://ulsterhabitat.org/ in the post Ulster Habitat News (facebook) (third image, first small one), the link to the facebook page will only open if: I right click on it and choose "open in new tab" (It does not matter if I give focus to the new tab or not), then I left click on the link and it works. If I left click on the link first, nothing happens. (link says "Ulster Habitat Facebook").

What I have done: run in safe mode, refreshed Firefox, reinstalled Firefox 43.0.3 (with all profile data removed - as clean as could be) with no extensions, altered settings or add-ons. Behavior is always the same.

System is Windows 7 Pro, latest up-to-date version, but Firefox also does this on a W7 Home system, and a W10 Home system, both with latest Firefox. No Firefox extensions or add-ons on the W10 machine.

Bonus: Chrome 47.0.2526.106 does not do this (it opens the link immediately). IE 11.0.26 does just what Firefox does. It would seem to me that the link should either work or not work, but not depend on opening in a new tab first. Fascinated by this. Thank you. Tim

Hi, I have been searching through the internet for a resolution, but each mention of an add-on or such for firefox leads to no-longer working pages it seems.

When I visit a website that has,for example, a list of 12 tips on a subject, (like 12 ways to annoy your cat ;)), it might show he first one, then i am supposed to click the forward arrow to see the next tip. However, i often find that it will not advance, unless i first refresh the page, then re-click the arrow, every single timei want to advance!

Is there a fix for this, or a good, updated add-on to auto-refresh?

Thanks for any help!
