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?

I just reinstalled my operative system, and with that my Firefox settings got reset. I know there is an entry in about:config to prevent ads from opening new tabs and pop ups without authorization, even from legit websites like the login pop-up windows when doing a sign in in Google, in those cases to allow the windows it's needed to click on the lock icon next to the URL bar and allow it from there. The problem is that I don't remember the name of that setting and I have spend an hour looking for it on Google.

I've read all the articles here about importing my passwords and history, but the Import Wizard is ONLY giving me the option to import my bookmarks. Even if I can't get the browsing history I need to be able to migrate my (extensive) password list.

I've exported my Safari passwords as a .csv file, but there doesn't seem to be an option to import a .csv file.

The page here regarding it says the feature is 'disabled by default' but does not say it's unavailable and I can't find clear instructions for how to activate the feature so that I can import my passwords. Can anybody help?

Hi Mozilla Community,

Currently on version 97.0.1 of Mozilla and have not been able to download any files from Google Drive.

When I click on a files to download it just keeps loading scripts at the bottom like - docs.0k.cc.googledocs.... and nothing happens.

I have read countless of links to solve the issue and still it won't download any files - only uploads is fine.

So I have: - clear cache/cookies - disable addons like Adblock etc - privacy & security set on Standard in settings - added cookies exceptions- googlecontent, googledrive etc - turned off Enhanced Tracking Protection

What else is missing as to why it has stopped allowing me to download files? Its quite frustrating when it use to work when I enable the third cookie party and now the setup doesn't seem to accept it.

Mozilla is my default browser and prefer to use it rather always switch to Chrome for downloads.

I've contacted Google about Google Drive and they said the problem is not on their side.

So any help would be appreciated!!

In Settings/Applications, have "JNLP file" set to "Use Java(TM) Web Launcher (default)". This is used in Oracle's Agile to view documents. In previous versions of Firefox when selected, the file would open using Java to display the document from Agile. As of Firefox 97, now only "Save File" or "Cancel" options are offered. What happened that this functionality has been removed?

I have a Win7 machine, and just bought a new Win10 desktop. I followed some instructions from a YouTube solution. From the Help>Troubleshoot>Profile Folder, I copied the profile folder (onto an external drive) and pasted it (from the external drive) onto the new OS(C:) as per instructions.

It did not work, I do not have all my bookmarks and extensions, etc. on the new Firefox browser I have installed on my new machine.

I don't know what to do now. All that was selected and overwritten is still selected on "This PC>OS(C:)" I was tempted to just delete all that shows selected...maybe not a good idea.

I really just wanted to migrate all my bookmarks, but doing the full profile folder seemed like a good idea at the time.... Help Mr. Wizard?!!

It is sad, I think, that Mozilla/Firefox is willing to close/archive a thread that is not really solved or has reared its ugly head again in versions since the release of 93 (we are now at 97.0.2). I came to this site and registered because I am still having this issue as of 3/6/2022...arg!

I have tried the 3 recommended solutions, with no affect:

I have, as one article suggested, cleared my cache and cookies, started and restarted Firefox; the only thing I have not tried is removing it from my computer and using Chrome (I'm told it is a better browser anyway) as some responders have eluded to.

I hope that responders like "jscher2000, Kymber" will continue the champion this issue until Mozilla gets it "Really" fixed.

Thanks for listening, Wayne

BTW, heres what my dropdowns look like today 3/6/2022 6:17 PM Arizona time.

Firefox Destroyed Session Restore

Firefox (97.0 64 bit, windows 10) destroyed all my previous tabs (4 windows lots of tabs) when I opened it despite always having "Firefox will" set to "Remember History". It just opened one window with the Home page.

Trying to sort it out using restore all tabs and then all windows, it just made the problem worse and the restored tabs eventually stopped restoring so now I have useless json files.

The files I have in my profile are:

previous.jsonlz4 15/2/2022 18:46 recovery.baklz4 15/2/2022 19:10 recovery.jsonlz4 15/2/2022 19:10 (this file changes its name from bak to json and back to bak again, very odd) upgrade.jsonlz4-20220119190439 26/1/2022 00:23 upgrade.jsonlz4-20220126154723 29/1/2022 04:31 upgrade.jsonlz4-20220202182137 12/2/2022 17:40

Is it possible "previous.jsonlz4" may have all the windows and tabs that I lost?

If so, how could I get Firefox to use it when I next open it? (assuming if I close this browser it won't overwrite the "previous.jsonlz4" file??).

Also could I use the upgrade.jsonlz4 file to try to restore all the windows and tabs that I lost? The windows would have been much the same on 12 Feb as they were today before the destruction.

A site that I use several times every year recently wouldn't open. Response from Firefox is "Access Denied - Certificate issuer not recognized". Also kept getting bumped out of my email account and all my open tabs would close abruptly. The last may have been rectified but I still can't get into the website I want to access.

I've tried different browsers as well so I don't know if it's Mozilla only or my PC. Even if I type in https://www.(pagename).com, it displays as you don't have permission to access http://www.(pagename).com.

I changed nothing on my PC that would cause the problem.

I'm running Win10. When in FF browser the taskbar, which I have set to appear at the bottom of my screen, does not appear. I normally use "auto hide taskbar" setting in windows, and tried to turn this off to see if the taskbar would again appear while using FF. It did not. So, the taskbar seems lost when in FF. This has happened before, appears it is an intermittent issue. My windows10 is fully up to date as is my FF browser.

Hello! Just installed Ubuntu 20.04.4 on my laptop and now find that I'm not able to watch some YouTube videos on Firefox 97. It seems mainly just live streams that I can't watch. When I go to one it shows "Your browser can't play this video...Learn more" in the video window. Clicking Learn More takes me to a page that doesn't explain what the problem is. Any idea what the fix might be? The same videos play just fine on other devices on my network. Any help would be greatly appreciated.

Firefox does not print the right edge of web pages that are made in landscape mode.

I set FF to "Fit to page width" but it does not print the right edge. It's cut off.

And there is no Orientation option available. Not sure if that has any significance because it supposed to "Fit to page width" anyway.

What's the work around to fix this?

Before if I wanted to refresh a page, I could click the refresh button or right click on the tab or page and select refresh.

And if I wanted to refresh the page but also delete the back history (AKA hard refresh), I would use a shortcut command like Ctrl + F5 or Ctrl + Shift + R. I had actually created a new shortcut Alt + ` to do that. And it used to work. It would delete my back history.

But for a while now, it hasn't worked. The hard refresh just acts like a regular refresh.
