For whatever reason the Picture-in-Picture button keeps not showing up in normal places like Prime, Netflix, Hulu, etc. I can make it come back by going to the Settings turning off the Picture-in-Picture option (Which is always still active) refreshing the settings then going back to Picture-in-Picture and turning it back on and then finally refreshing the video I was trying to use, but this is kind of a lot to have to do every time it happens and it seems to be happening more and more, so I'd like to fix the root cause instead if possible. Any ideas?

I want extensions to have white/black-lists, so they're only allowed or blocked on certain pages e.g facebook container ruins instagram experience... and I can't block it on *instagram.com* Such feature would significantly enhance UX on firefox

Thanks, Rob.

Is there a way I can disable the "Pop out this video" button on the video player itself but keep the toggle present in the url bar? I have attached the pictures of what I am talking about I don't like the pop out button appearing on the video everytime I try to use my mouse around the video player but like the option of picture in picture seems like a good option for me.

Currently if I try to disable the button from the menu after right-clicking, it also disable the button present in the url bar.

Cannot prevent intrusive unwanted video on some pages; notably, CTV.ca which has an annoying widget which autoplays constantly and blockers are not effective, neither is video.autoplay.default=5 That USED to be the default no-fail go-to, now it has no effect whatsoever and I'm stymied in my attempts to block this stuff. What's next? How do i do this?

My extension is greyed out in the Extensions drop down. I have redeployed it in the Mozilla Developer Hub but to no effect. It has been down for a couple of days. What could be the reason behind it and how can I fix it?

I'm using Firefox for Windows and usually have a few set pages that appear every time I open a new window. Every now and again, I have to add, remove, or change one of these pages. The issue is that I have to see something like this whenever I want to change anything.

`https://link1.url.com/|https://link2.url.com/|https://link3.url.com/|https://link4.url.com/|https://link5.url.com/`

Naturally, whenever I open a new window in Firefox, this is automatically interpreted to open multiple pages. However, this way of displaying them is still inconvenient. I want to know if we can get something more like this.

https://link1.url.com/ https://link2.url.com/ https://link3.url.com/ https://link4.url.com/ https://link5.url.com/

Is there a way to edit the Settings UI to see a multi-line list with the ability to add, remove, or change these links individually? Thank you.

Some websites, like my bank, don’t let you paste into the password field. I don’t want to manually type in the password. I found a workaround:

1. Go to about:config
2. Search for dom.event.clipboardevents.enabled
3. Double-click it to change the value to "false"

But the problem is that pasting into a google document no longer works. I have to revert the value back to “true” to get copy-pasting working in a google document.

Is there a way to have the best of both worlds: paste in google docs and paste in sites that block pasting, like my bank?

Hi all,

Using: Firefox 119.0.1 (64-bit) on Windows 10.

I seem to having an issue with adding search shortcuts on FF, I am following this guide:

https://support.mozilla.org/en-US/kb/assign-shortcuts-search-engines

But I'm stuck at step #4 as the table seems to be disabled.

This is a personal laptop and has not policies on it.

Thanks for your time and assistance!

I have two PCs, both running the same versions of Firefox for years. A little over a year ago, after an update, a new "Private" icon appeared in my taskbar in addition to the normal Firefox icon on one of my machines, but not the other one. This presented, and functioned as two different, independent browser applications; I could just click on the private browser icon to open the private browser without opening the "regular" Firefox. I don't know where this came from, but I like it... but it never changed on my other PC, and I can't find how to apply it; is there a setting or something I'm missing? Why did it happen automatically on one machine, but not the other?

There are many cathegories to filter addons at https://addons.mozilla.org/en-US/firefox/extensions/ sadly none to sort by popularity. A popularity filter to list firefox addons would be a great feature.

Speaking of great features, addons.mozilla.org should not use google-analytics.com Mozilla on the one hand promotes privacy or atleast makes the impression of doing so, but on the other hand tracks their users by default and uses google analytics on their extensions website. There are privacy friendly alternatives to google analytics, why did Mozilla decide to use an invasive bigtech option? It is very unlikely for mozilla to quit using google analytics just because of this thread, and even if i asked on the apropriate forum or email chances are nothing will change. It's just sad mozilla uses google analytics, there's nothing else to say.

Another question, Mozilla in this article https://addons.mozilla.org/blog/firefoxs-most-popular-innovative-browser-extensions-of-2021/ claims that there have been a total of 133 million visits to addons.mozilla.org However this site https://www.similarweb.com/website/addons.mozilla.org/#overview claims that addons.mozilla.org had a total of 10.9 million visits over time, which seems incorrect since ublockorigin alone already has 7 million+ users. I've always thought that similarweb is a reputable source, or maybe not?

Hi. I've used Firefox as my main web browser on desktop computers for over a year now, and it's so far been the best web browser I've used.... except for one issue when it comes to major updates to the app.

I have Firefox set to open up on the tab/site I was using before I end a session and close the app. Whenever there is a new major version release, the update gets installed the next time the browser is launched before showing the browser window. But, when the window opens back up, I'm not sent back to the site/tab I was previously using. A new tab automatically opens up to a Mozilla page saying that Firefox has updated, along with a large promotion for another Mozilla service.

I then need to manually close this new tab, and find the tab I was previously using during the last session before the auto-update. This is mildly irritating since it takes some control away over how I want Firefox to start up, and the new update tabs seem to just be used as a way to promote other Mozilla products seeing how the actual "Firefox has updated" text is very small.

Is there a way to turn off these automatic new tabs after every major auto-update? Or if there isn't, could an option to change the way Firefox notifies about updates be added in a future version, such as using the OS' notification option instead of opening a new tab?

Currently running the latest version of Firefox on an iMac, with Mac OS Sonoma.

In HTML, in the head element, it is possible to specify links to external resources that are relevant to the current page. For example:

<link rel="alternate" type="application/pdf" href="mypage.pdf" title="My Page in PDF Format"> <link rel="license" href="copyright.html" title="Website License Information"> <link rel="next" href="page2.html">

Many years ago, I found an obscure setting that enabled a toolbar that would display all those document links directly in the browser. That was several computers ago, so I cannot look up the about:config setting that enabled the functionality, and my online searches have found nothing even remotely related to the subject.

What happened to that functionality? How can I turn it back on inside the latest version of Firefox?

Addendum: This functionality was not provided by any extension, add-on, or mod. It was implemented directly in the browser itself, downloaded vanilla and clean installed. It was enabled by directly editing the "about:config" page.

As for whether the cited links are intended for automated tools or not, here is the HTML standard itself:

Interactive user agents may provide users with a means to follow the hyperlinks created using the link element, somewhere within their user interface.

And just in case somebody suggests this is somehow new or novel functionality, here it is described in the HTML standard published in 1997:

Although LINK has no content, it conveys relationship information that may be rendered by user agents in a variety of ways (e.g., a tool-bar with a drop-down menu of links).

That "tool-bar with a drop-down menu of links" is almost exactly what Mozilla used to provide. I just want to know what happened to it.

It has reinstalled all my other extentions, but hasn't my password manager for some reason. Or at least I can't find it. I also can't remember the name of it, and so don't know what to search to download it again. Is there a way to see historic extentions or something?

I often see a Shortcut on my New Tab that I have never gone to, which says "sponsored" on it. I do not want these ads. I have looked up the answer: https://support.mozilla.org/en-US/kb/sponsor-privacy?as=u&utm_source=inproduct I can manually delete a sponsored shortcut once, but this does not stop them from coming onto future New Tabs. My problem is, the long-term answer simply does not work. Settings -> Home -> Firefox Home Content simply does not contain a section that says "Sponsored shortcuts" and therefore this solution is not accessable. I am on Version 120 as suggested. What is going wrong? How do I prevent these ads from appearing on the New Tab page?

I have an issue with the address bar in private windows. Normally when you click on the search bar in the new tab page, it will redirect the cursor to the address bar instead of letting you use the search bar.

I found the following solution on the forum here that works for normal windows: go to the about:config page and set browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false.

For private windows, this fix does not work. It will still go to the address bar instead of letting you use the search bar. Is there another way for me to fix this so that it will also work in private windows?

Hi, I got a new laptop recently and ever since then I've been experiencing this problem. Websites like https://tabs.ultimate-guitar.com or https://ukutabs.com offer the option to autoscroll, so that you can play your instrument without having to pause your playing and scroll further yourself. This feature hasn't been working for me ever since I got my new device and since it's various sites, I suppose the problem must be in the browser itself, I just can't figure it out. In the case of Ultimate Guitar, when I click autoscroll, it does move slightly, once, but then stops again, and you'd miss the movement if you're not paying close attention. I can switch between various speeds on this site as well, but it doesn't do anything. In case of Ukutabs, there's not even any kind of response from the site when I click the option. I tried turning on and off Firefox settings concerning autoscrolling and smooth scrolling, but nothing solved my problem.

Thank you for your time and energy, everyone!

I would like to know how I can middle click with my scroll wheel to open a bookmark in a new tab, but not be dumped straight into that new tab. I like opening multiple tabs at once before going into them.
