I am running El Capitan and need Firefox 78. I went to a site offering 78 as a download, and version 91.5 came down. Site offering 78esr, same thing. Went to https://ftp.mozilla.org/pub/firefox/releases/ and was unable to figure out how to download 78. Clicking on 78.0 just led to more links that got me nowhere. Is it possible to download version 78 from this or any site? Thank you. heaton5

On ubuntu 20.04, the snap version of firefox can't play some videos. Some youtube videos will play but streams won't, and then I get the message "to play video, you need to install the required video codecs". On telegram web and tweetdeck I also get this message while trying to play some video.

Since it's a snap, nothing I do on my system will solve the problem, I cannot install any codecs.

It's firefox 89.0

Ever since the last update, every time I download something on Firefox this download tab pops up every time when the new download is complete. Ive tried disabling every extension, Ive tried the about:config solution I found on this page, setting it to "false" and I havent been able to find anything in tools or settings.. but nothing disables it and its getting annoying. Ive had Firefox for years and this has never happened before.

Hello. I and a friend of mine are having trouble with firefox, it seems to be using excessive ammounts of ram as pictured. I only had two tabs open and two addons installed when I took that screenshot. Any help would be appreciated, thanks in advance.

After installing Ubuntu 20.04 LTS Clicking on Firefox or Thunderbird it hangs the computer and have to switch off the computer on main switch. Reinstall Mozilla once but no difference still hangs Ubuntu. Need help on this one Thank you

Awhile back [the question was asked], however the 'solution' is not what we are after here.

Once upon a time, there was a table with the Firefox downloads. And in previous versions. That is what I am looking for. I do not care, repeat, do not care, about the form input selecting 'latest' platform, etc.

Assuming also there is a method of downloading offline installers using tools like wget.

Thank you...

I am running window 10 on my laptop and Firefox started opening today in a small window in the upper left of my screen. I have no problems with other browsers but Firefox is doing this repeatedly today. I will reboot and see if that helps.

I run FF on both a Windows machine and a MacBook Pro. On the MBP the browser does not save my tabs, despite "restore previous session" being selected. I do not have this problem on the Windows machine.

I have tried uninstalling and reinstalling the browser but it has not made a difference.

I'm running the latest version of the browser and the OS is Big Sur.

Ok so it's been a long time that i left chrome and joined the firefox community but there was always something which felt left out, so i downloaded chrome again and found what that was. It was the size of toolbar.. In chrome toolbar is smaller but in firefox it takes some space. So i want smaller toolbar here in firefox because i love every other thing here. So is there any way to do this? Thanks,.

WidevineCdm plug-in crashes everytime when I try to play disney plus or amazon prime. I fit the requirements via the disney plus site. Can anyone assist? I was streaming fine last week and now its not working.

I need to know when a visitor to my site is clicking the back or forward button. The reason is I have a "tabstrip" that hilites the currently selected tab and the target document is displayed in an iframe. If I click the back or forward buttons the page is updated with the last or next document in the iframe, but the tabstrip is not updated to reflect the change. Part of this is due to me not knowing how to update the tabstrip, but also because I don't know how to detect the back or forward buttons being clicked.

So I need to know how to detect those button clicks. Also, in researching this, I noticed that there seems to be an idea that you can't distinguish between the forward and back button, only that a button was clicked. That doesn't make sense given that each button has a specific action that is opposite of the other. I need to know the truth about this.

Finally, as much as I use only Firefox myself, I know there will be others who use other browsers. Is there any difference between detecting the back and forward buttons on other browsers compared to Firefox?

One of the pages I need this for is here

Edit 15 March 2022:

I had to fix the link because I had renamed the page when I finished the work on its layout. Also, since I asked this question I have realized another similar and sort-of related issue on a different page: https://wayneca.neocities.org/WebDesi.../TagList.html. The relation is that the back and forward buttons don't correctly reload the page. The difference is that this one is concerning named links.

When you click a link in the table on the left it correctly moves the document in the right table to the point where the matching id anchor is. But when you click the back or forward button the tables do not shift back to where they were on the page as reloaded. The back and forward buttons work fine if the link anchors and id anchors are not in tables.

I have been told about the history functions, but I have found no examples of using it to correct the issue in either of the above cases. Is someone here able to point me to examples of using the history to make a selected link reset back to where it was or reload a page with the last jump point being reset correctly?

Also, why does the named link thing work without tables but not with tables?

Getting error SSL_ERROR_BAD_CERT_DOMAIN on all my sites that are signed with a SSL Cert from my internal CA since updating past version 99

This appears to be a bug starting after Firefox version 99 on Windows because after i upgraded to Firefox version 100 i started getting this on all my SSL Certs from my CA and they worked fine prior to the update. Can anyone confirm if something changed after version 100 that is causing this?

Thank you.

Following a Windows 10 update, I tried to open Firefox and the following popup message appeared. "the code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem." I have tried several times to download the latest version of Firefox, but during it's installation the same error message appears. How can I fix this problem and get Firefox to work normally.

I'm trying to take off this "Extension (Tabliss)" tag on my url. I have followed the instructions down below from another Firefox support forum: https://discourse.mozilla.org/t/make-addressbar-text-extension-name-of-the-extension-shorter-or-hide/28026/3

The instructions I followed are listed below:

"Users can apply custom style rules to modify Firefox’s toolbar area by creating a userChrome.css file. This takes about 10 minutes so when you have time to take it slowly and carefully:

(1) Set up your chrome folder and userChrome.css file following the five six steps in this article:

https://www.userchrome.org/how-create-userchrome-css.html 45

I have a boring video there if you like demonstrations.

(2) This is the code to paste into the file. You can edit the file using Notepad or a better editor. Make sure to keep it in a plain text format with a .css file extension (not .css.txt).

See improved rule down in: Make addressbar text "Extension (Name Of The Extension)" shorter or hide

/*
   Hide Extension Name in the identity area unless
   hovered for half a second (updated for Fx80)
*/
#identity-box.extensionPage #identity-icon-labels,
#identity-box.extensionPage #identity-icon-label {
  visibility: collapse !important;
  transition: visibility 250ms ease-in-out;
}
#identity-box.extensionPage:hover #identity-icon-labels,
#identity-box.extensionPage:hover #identity-icon-label {
  visibility: visible !important;
  transition: visibility 250ms ease-in-out 500ms;
}

(3) Firefox should read the file at its next startup and apply it to every extension page you load."

Edit: So, yeah, I need help getting this tag off. I'm new to Firefox so it could be something obvious I'm missing. I have also tried CTRL+SHIFT+R to reload the page for changes and also closed and reopened my Firefox entirely.

Thanks in advance.

Since I updated to Firefox v.91.0 I get this error:

Secure Connection Failed

• An error occurred during a connection to support.mozilla.org. PR_CONNECT_RESET_ERROR

• 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.

when ever I try to connect to websites via Firefox only. I've tried many things like reinstalling Firefox and I know its an issue between Firefox and my Antivirus (Kaspersky,) but this didn't happen before Firefox updated to v.19.0 though. I've tried https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can and many other things but nothing works to fix it. I've switched certificate stores and other 'fixes' I've read on this website and others to no avail. It does this with or without any extensions in Firefox.

This only started when I updated Firefox to version 91.0. It doesn't give an errors/issues on any other browser I've tried so far (MS Edge and Chrome) so must be something with the version 91.0 update?

Any ideas to fix this would be great. Thanks!

How do you remove The Firefox Title bar from my desktop? It prevents me from clicking the "Accept or Decline" buttons for example on software installs for example. on your support page I tried the "firefox menu> + customize & disable the title bar through the button in the bottom left corner of the window". There is no "customize" option.
