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?

In the latest Firefox update a very annoying new "feature" arrived. When you download something, an automatic drop down menu appears in the top toolbar and stays there until the file is being downloaded and closed after some seconds after the download is finished. You can click of course somewhere to make it vanish.

This is TOO ANNOYING. It also covers a portion of the main page. How can i disable this behavior and return to the old one where nothing appears automatically?

I cannot watch a video on youtube when it is in the process of being live streamed. I remember a time when I was able to, years ago, but I can't any longer. I'm not sure what has changed. I found an article that says to install the optional update called "Windows Media Pack" in apps and features, but no app with that name exists. It was only a year old solution, so I'm unsure of what changed so significantly. I just installed another optional windows update, and also updated the browser, but still doesn't work.

I'm not sure this is a problem with Firefox but I have run out of other options to look at. At first I thought it might be because the page uses a frameset (I know it's obsolete) so I created a version that uses an iframe instead. That way the html that needs to be acted on is not in a frame. It still doesn't work. I don't know why it works in stackoverflow's sandbox and jsfiddle but not on my website. Any help is appreciated.

Frameset version iFrame version

If you need to see the tabstrip code (it's virtually identical to the iFrame version): Tabstrip for frameset version

The script is supposed to hilite the selected tab with a red background. The rollover works fine (yellow background and brown text) but the selected tab color never shows up.

I like to mute all of my tabs so they don't play annoying sounds. However a very annoying mute icon appears when I hover over it and the "muted" text is shown under the name. I tried adding to my userChrome.css:

@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul); .tab-icon-overlay[muted], .tab-icon-sound[muted] {

 display: none !important;

}

This only removes the muted icon, and when I hover over a tab its favicon disappears. I also tried changing browser.tabs.showAudioPlayingIcon as suggested in [answer] but it isn't an option anymore.

How do I remove it completely without changing the context menu item?

I have set Firefox Developer Edition (Windows 10 20H2 & 21H2 and Ubuntu 18.04 & 20.04 installations, always kept up to date), to use English (United Kingdom) settings in preferences. I have installed the UK Dictionary and made it the default for spellchecking. The Windows installation is also supposed to be respecting the OS regional settings. Firefox seems to be totally disregarding the settings and always giving me US as the location and US English for the spellcheck. This has been an issue for months if not years. I understand that many pages will be US biased, that is not a problem. The problems are that my country preference is being detected as US, and that I can not seem to get Firefox to actually use the UK Dictionary. I can supply additional information as required

I'm using Firefox to save my passwords, but I'm having troubles in having a good experience with it now that lockwise is gone. And lockwise was not perfect either but still better.

If I create a new account on an app Firefox doesn't provide a way to autogenerate a password and then save the login data.

Please improve this feature because it is vital, especially if you deprecate the alternative.

Recently I upgraded my Windows 10 to Windows 11 and since doing so, I've had consistent errors while browsing the web on Firefox. Most notably the "Humm. We're having trouble finding that site." error message.

For example, when visiting, say Verizon.com, the tab will display the aforementioned error to which I press Try Again and the website loads correctly every-time. No hiccups on the refresh.

I've tried the following:

  1. I've performed a completely clean uninstall of Firefox and then reinstall
  2. Cleared all browser history/cache
  3. Removed all extensions
  4. Disabled IPv6, HTTPS Over DNS, No Proxy
  5. Ran through Firefox's troubleshooting
  6. Used Firefox Troubleshooting Mode in the Browser
  7. Tested that the problem does not happen while using Edge

I've never had a single problem on Windows 10 with Firefox. Curious if others are experiencing the same issues and if there are any fixes. Nothing else on the PC has changed.

  • Windows 11 21H2 2200.348
  • Network driver is the latest Win11 edition

I used Apple Migration Assistant to move the entirety of my wife's old iMac (the old computer won't accept updates, so her machine was not secure) to a new one. The migration operation appeared smooth and essentially perfect.

Somehow my Bookmarks have overwritten my wife's (years ago, I turned Synch = ON, was that it? Synch is OFF now). The bookmarks are still OK on the old computer, so how do I locate and move that info to the new machine "AND BE SURE TO GET IT RIGHT"? My wife is the family business manager, so her bookmarks are Insurance, Banking, Healthcare, etc.

I've done some searching, but there are thousands of posts, I can't wade through all of that.

When using the dark theme from Firefox, Google searching seems to break completely as well as some pages will not load which may be related to this.

I have already tried uninstalling Firefox, deleting all of the folders, then reinstalling with a freshly downloaded installer (Even tried the beta one) with same results. It seems potentially MAYBE related to how long ago I closed Firefox before I shut down (Like Firefox is trying to save something to a secure location and times out, then it will work but if it hasn't timed out, then it crashes... or this is my guess)

The Signature seems to change randomly for the crash between crashes.

Great news about Firefox being added to the Microsoft Store. It seems to me that method of keeping Firefox up-to-date might be more effective than the traditional Mozilla background service. However, I use the Beta channel. Is there any chance that channel will be added to MS Store? Regardless of the version I assume that you have to completely uninstall the conventional Firefox install and lose all your about:config and other settings (anything not included in Sync).
