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 recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

Hello, I have issues with Firefox developer version for couple months now, when I play videos, like youtube, or other sites they constantly lag. They play for like 1min and lag, continue for another 2min then lag etc etc. (even short videos on twitter lag). It was not like that before and I don't have this problem in other browsers. Does anyone know what can be the problem here? Thanks

I have tried all of the about:config options to disable the auto-reload of the tabs. I have this working fine on my old machine macbook pro 2015 (same firefox version), but on the macbook pro 2019 i cannot get it to stop. Any help would be great as I need to switch between tabs during meetings and dont want them to keep relaoding

I recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

Hello,

Whenever I use Firefox, I end up seeing popups (necessary for school) and would like to show them as tabs so I can merge them into other windows. I have tried the solutions given in: https://support.mozilla.org/en-US/questions/1080255 and nothing seemed to work. Is there another way to make sure that popup windows cannot hide the toolbar and show tabs?

Hello.

It seems I get a problem or two almost always with a new update lately. I have been using an userChrome.css to reduce the width of sidebar but the latest version 107.0 now ignores it and have a wide width even at the narrowest. Mine currently is set as, "#sidebar {min-width:30px !important; max-width:none !important;}" This no longer works. Your support much appreciated.

Regards,

I've got a new computer I am setting up from scratch, and though I have set FF to sync settings, I'm still having to customize a lot. My bookmarks toolbar is crowded again with icons and I'd like those to go away. I don't mind other icons staying around on the tabs--that does help me navigate faster. I had this set up before, but lost the setting when I refreshed Firefox.

I first realized an issue with downloading PDFs through the Firefox viewer - I cannot. The download button does nothing, there is no prompt, no popup, and no file downloaded. I have also tried to print to pdf, that also seems to fail.

Today I realized I also cannot attach any files to an email through Gmail in Firefox, which is now leading me to believe that the software is unable to interface with my files at all.

Things I've tried include: - Turning off popup blocker - Refreshing Firefox in the ->Help->More Troubleshooting Information Menu - Starting Firefox in safe mode - Reinstalling through snap

The only way I can currently download files is through wget, and the only way I can send attachments is by installing Google Chrome, which is kind of a last resort for me.

I am running Ubuntu 22.04, this is on Firefox 106.0, though it didn't work last update either.

Thanks for any help

Edit: I have been googling for answers but after posting this question a similar thread popped up, the solution is to install the following packages:

xdg-desktop-portal xdg-desktop-portal-gtk

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.

Edition Windows 10 Home Version 21H2 Installed on ‎09-‎Jun-‎20 OS build 19044.1466 Experience Windows Feature Experience Pack 120.2212.3920.0

In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

Is there any way I can completely disable horizontal scrolling? I'm using a laptop with a trackpoint (lenovo x230, Windows 10) and it's not terribly accurate, which means scrolling whilst a youtube video is going often makes it track backwards or forwards, and another website I use uses a horizontal click to send me to the next page, which sucks. I would prefer to just be able to disable it entirely. Thanks!

I swear to god I used to have it disabled, just need to work out how again.

I had set up a userContent.css file in the past to pull up and fetch an image on my computer to display as a background on the homepage. It worked and did it's job until recently, when I had recently relocated a lot of my files around on my computer. I have redirected everything to where I want it to look, including the userContent.css file to the new location for the image I want as the background. Firefox loads the .css file correctly, and recognizes the file existing, but it won't load the image itself for some odd reason. It states it "may not load or link the file" because of a security error, and thus, can't load the image. I never had to deal with this before. How can I get Firefox to be able to load my image like I want it to? I have screenshots that I can provide, but this site doesn't want to upload them at the moment.

Hello, I would like to know how to remove 'other bookmarks' folder from the right side of bookmark toolbar that showed up suddenly on my browser, it's right after the arrows to show more bookmarks. I can't seem to find a way to delete this.

Greetings. I can't open most sites I usually visit (even google.com) via my Firefox 98.0a1. This happens since today. All error codes are SEC_ERROR_LIBRARY_FAILURE.

Tried to:

• Disable DNS-over-HTTPS.
• Disable HTTP/3.
• Disable proxy (never had it enabled anyway).
• Disable sending info to Firefox developers.
• Change settings of DNS-over-HTTPS.
• Restart the browser (after each action).

Nothing helps me... But I still can visit some websites, but most common resources are not working for me. Please help me because I can't use Microsoft Edge without getting mentally ill. :/

Hello, I can't access the home router. 192.168.1.1 results in "Secure Connection Failed" and nothing can be done. How can I solve the problem?

I'd swear that I used to be able to click on an animation/video/gif to stop at looping, but I cannot stop this one by doing that:

https://d2rdhxfof4qmbb.cloudfront.net/wp-content/uploads/20190129121540/facts-min.gif

It must've been one of those custom settings I had before I got the new computer and ran a clean install of firefox.

I have set media seamless looping to off in about:config, but I can't see what other preferences would relate to this.

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?

So, certain web pages apparently have text in white font color while also using a white background. I'd blame it on the team behind the page, but it seems that it works well on Chrome, so I'd like to know how to fix it.

I'd add images, but they take way too long to upload
