How do I remove the scam pop-up that won't let me access firefox on my iphone? The pop-up says "your apple iphone is severely damaged." I can't open a new tab or delete the current tab.

When I play a video in fullscreen, there is a strange black border that appears around the video which makes the content smaller than it would otherwise be. This border does not display in Safari or Chrome, just in Firefox. It also occurs in every media player I've tested, including YouTube and Netflix.

Annoyingly, I can't get this to show up in a screenshot. It seems like Firefox guesses the aspect ratio or resolution wrong when it puts media in fullscreen, and it has the effect of downsizing the actual interactive part of the display. Meaning, I can't move my mouse into the border area to take a screenshot of it.

I'm on an ARM Macbook running MacOS 13.5, if that matters.

Is this a bug, and/or is there a way to fix this?

After Firefox upgraded from 114.02 to 115 menu and tabs background color changed:

FF 114: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2023-07-05-17-00-30-1a3adf.png FF 115: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2023-07-05-17-00-34-cba7e0.png

These are screenshots of active window. When window of v115 becomes inactive, background color changes to lighter, but still no visible horizontal line between menu and tabs. I don't use any additional themes, "System theme — auto" is selected.

From release notes for FF 115: For users with a Firefox Colorways built-in theme, the theme will be automatically migrated to the same theme hosted on addons.mozilla.org for Firefox profiles that have disabled add-ons auto-updates. This will allow users to keep their Colorways theme when they are later removed from Firefox installer files. I guess it is relevant somehow, but i never installed Colorways and don't know what is it.

How to make FF 115 look like it was in 114? I can see changes in `browser/themes/` in sources between 114.02 and 115. Is it possible to "extract" default theme from 114 and install/apply it to 115?

I use Firefox under Fluxbox window manager in Arch Linux, if it matters.

I have my Firefox Firefox Privacy & Security History settings set to 'Always Use Private Browsing Mode.' Yet every time I open Firefox and visit the History tab, 'Recently Closed Tabs' shows a history of the websites I've visited. How do I disable this feature?

Hello. I recently moved from windows to Linux Mint, and noticed the behavior of the Picture in Picture window is different when resizing. On windows, the aspect ratio is kept. while on Linux, it is free form, making these black bars around the video, so I have to resize it very carefully to not show any black bars.

How can I make the PiP on Linux behave like on Windows? That means resizing keeping the aspect ratio.

Attached are the comparisons between Windows and Linux Mint.

Thank you very much!

I've been searching for a solution on HOW to edit HTML files (for websites) on my new laptop. I used to use IE11 (Internet Explorer 11), on Windows XP / 7 (32 bit), which worked spot on, the steps were as follows: (I write websites from scratch most of the time) 1) Click on, say, index.html 2) IE11 shows the actual page 3)Click on View/ Source 4)The source code shows up in Notepad 5) Edlt the code, Save and click Reload the webpage. You can straightaway see the changes.

Currently my new laptop runs Win 11 pro, Microsoft does NOT support IE11 anymore, I can however run IE11 as a add-on, BUT it does not work very well . I also tried a couple of free dedicated editing programs also, BUT they are exceedingly clumsy to use and can't equate to the old IE11 at any level. Somewhere I read that Firefox ( i have v115) can emulate what IE11 could do, hence I am on this forum posing the question, as i can't find the solution,

Anyone in the same boat?

Please share your ideas, Many thanks

I noticed that someone else had this question, but instead of answering it, it just got archived.

When browsing Youtube, the browser Back Button doesn't work. For example, if I start on the Youtube main page, then click on a video, it will show the video. But then, when I click the browser's "Back" navigation buttion, it does not take me back to the main page. The URL in the address bar will be the main page, but it will continue to display the video I just watched instead.

This only seems to happen on Youtube. It's been a problem for a while - possibly as much as 2 years or even more. And it doesn't happen every single time. However, it has been happening a lot more frequently lately.

It's almost as if Firefox just doesn't want to refresh.

I've tried clearing the cache. The problem persists. I've dried disabling all add-ons. It still happens. I've tried running it in troubleshooting mode. Still a problem.

I've tried to duplicate this in Microsoft Edge; it doesn't seem to happen there.

When I launch Firefox (version 115.0.1), it establishes and maintains multiple connections to '*.googleusercontent.com' until I close Firefox. This is bull shit is totally unacceptable. I have been using Firefox since version 1.0.6 but I will dump Firefox for another web browser if this problem cannot be fixed.

How do I stop these connections being made?

After removing elements from a website with another add-on, I'm left with a considerable white gap at the top.

I can manually change (pointless) the margin-top property to -100px, but how do I do this with the Stylus add-on?

Stylus doesn't like negative values:

margin-top -100px

10:20 Expected "{" but found "-100px".

Is there a lighter/simpler alternative to Stylus?

I get this when trying to get my email from Comcast:

Secure Connection Failed

Error code: PR_CONNECT_RESET_ERROR

If you have multiple tabs open and you hit Ctrl-T to open a new one, it opens it at the end of the tabs, and the cursor focus moves to the URL bar so you can start typing in an address/search.

If you right-click on any of those tabs, it opens a new tab to the right of that tab, instead of at the end (which is what I want, as right-clicking on a specific one to open a new tab, to me, means you are linking those tabs in layout and want them together) BUT the cursor focus DOES NOT move to the URL bar.

This seems pretty counter-intuitive, and means that so many times I right-click, Open New Tab, and start typing a URL and then see that I have to stop typing, click in the URL bar, and start typing all over again.

Is there an about:config to force the focus to the URL bar, or is this a bug? If there's no setting for this, I would definitely consider this a bug because you have 2 different behaviors for New Tabs.

My community association uses Constant Contact for its documents, notices, etc. When I get an email message from them, it often contains several links beginning with https://r20.rs6.net. When I try to access one of those links, Firefox tells me "Hmm. We’re having trouble finding that site. We can’t connect to the server at r20.rs6.net." Chrome and Edge do not give the same error - they can access the requested page. Is there some setting in Firefox that I need to change to fix this problem? Firefox has been my default browser for years, but I also like to read notices from my community association.

Any extensions I install suddenly don't show up in my toolbar or the customization menu anymore, so I also can't drag them there manually.

Deleting the extensions and re-installing them didn't work, neither did deleting the extensions folder itself.

Does anyone know how I can fix this? I've attached a screenshot of the customization menu and extensions menu below.

Thanks :)

So I'm using firefox on my old PC and want to export the login data to my new PC. Firefox has export passwords to CSV but there is no import CSV in firefox on the new PC. There's import HTML but... firefox exported to CSV not HTML so I'm really confused, why would it export to a format that cannot be import?

I am currently running Firefox on High Sierra 10.13.6 and have been advised that that OS will soon no longer be supported. I did have an option to do an update to ESR 115.1 in my Firefox app, however I was not home for a few days and when I returned planning to do the update it was no longer available. Now it just says my Firefox is up to date with 115.0.2... how can I get the update to the ESR 115.1? Thanks!

Hi all, I use to update Firefox with my Linux distribution package: I build the new package then upgrade it on the system. Anytime at the first launch of the new Firefox just installed version, it opens a new blank profile instead of my usual profile. I can set my usual profile as default by launch Firefox Profile Manager. So after update I launch from command line terminal or through launcher bar:

firefox -p

And It starts up profile manager, then I choose my usual profile and check it as default one. After that, when I open Firefox again, it uses my usual profile as expected.

Now the question: - is there a way to automate this procedure so I have not to repeat it anytime after I update the browser?

PS. I noticed my "profiles.ini" file is populated with a lot of profiles sections, likely maybe anytime I update, a new one is added in here. I don't know if it is a regular behavior or not.

So, whenever I open Firefox it will act normally and then after a second close by itself and when I reopen it, it will be in remote mode. I know how to fix this via about:config and do this every time, but I would much prefer a permanent fix, nothing else on Firefox or my computer indicates something else is going on, its just this. I've even at one point uninstalled and reinstalled Firefox and it didn't help.

Whenever I type something in the URL bar that starts with the word "amazon," instead of getting a Google search for what I typed, I get redirected to Amazon.com with whatever I typed as a product search. For example, if I type "amazon sucks" in Firefox's URL bar, instead of getting a Google search for the phrase "amazon sucks," I get an Amazon page with the word "sucks" pre-filled in Amazon's product search (and a screen full of socks).

I don't have a search keyword for "amazon" in my Firefox settings. As far as I can tell, no other magic word does the same thing. (For example, if I type "yahoo sucks" or "walmart sucks," I get the desired Google searches. I don't get redirected to a Yahoo or Walmart page.

How do I turn this behavior off?
