I cannot login into a website because they complain that I have an old version of PHP. Is that already included in Firefox? I am using Firefox Vers. 143.0.4 on a MacBook Air with MacOS Big Sur, Vers. 11.7.10 Shall I go to the PHP website and download PHP?

I opened Firefox on one of my computers as usual today but the whole performance changed. Used to go to my home tab and select various news sites to see what was happening. First, when I scroll down the bookmarks, I would hit the "news" and click on it so all the sub items would stay in the scroll, but instead of that, it wanted to open every item as a new tab. When I finally started opening the various news outlets, it opened them in new tabs, it had always opened in the same tab. Then, I couldn't close the various tabs it had opened. I would go to the tab and hit the "X" but it didn't close the tab. I had to use a drop down menu to close a tab. And when in a site, I used the scroll button on the mouse, instead of scrolling, it made the page larger or smaller instead of going up or down. What could make such a change in behavior? I opened up the 'settings' on it and looked at 'tabs' and they were the same as the ones that are on this computer that works as expected. Both computers have it set to open all previous windows and tabs. Both have the same settings for 'tabs' and 'browsing'. I don't get it. Both are version 143.0.3 (64-bit) I have Ubuntu OS.

Is there away to prevent the auto-unhide of the menu bar in full screen mode when the cursor moves to the top of the screen? I have searched for answers to this and found some old posts about creating a userChrome.css file but I couldn't get it to work.

Here's my use case. I access a remote desktop through Citrix for work. I use a browser via Citrix Lite instead of Citrix Workspace because the desktop will dynamically adjust to the window size when I don't need it in full screen which Citrix Workspace will not do. However, the auto-unhide feature of menu bar when the browser is in full screen mode also causes the desktop to dynamically adjust when it drops down and again when disappears. This forces me pause when trying to work because it happens often since I'm using a a large monitor with multiple applications open with tool bars on the top rows. I know that I can not hide the menu and address bar but don't want to lose the extra screen real-estate. I would much rather have a keyboard shortcut to reveal the menu bar or some other option.

In version 143 there is no rollup window option that allows a linux system to roll the window up out of the way. The icon is a caret located in the top right corner of the window.

I am using version 143 for Linux and it is suppose to have improved fingerprinting protection. But when I go to https://coveryourtracks.eff.org i still see a result that says "your browser has a unique fingerprint"

Is there a parameter I should be enabling ?

Hello..

Trying to make the Firefox as my default but... the Web browser" is not visible in Settings.

PLEASE guide me to the right link..

At this time the Microsoft Edge is selected permanently.

Any suggestion is welcome.

When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.

Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):

• github.io (many subdomains)
• purdue.edu (many subdomains)
• iu.edu
• ebay.com
• cbsnews.com
• iwm.org.uk
• home.cern
• celestrak.org

Any help in resolving this is appreciated.

When I type in a Google search in Firefox, a red dotted line (not the wavy red line from Firefox's spell check; spell check is disabled) appears. What exactly is this red dotted line? Can I show or hide it in settings? Can I change the setting in about:config? Please help. It's very annoying.

My problem is the following. The website of my favorite football club regularly embeds videos within their pages. Clicking of the video within the club webpage shows the video without leaving the webpage. Recently opening the club site with mozilla stopped enabling me to see the embedded videos. An example of what I see on my screen now when using mozilla is in the first image uploaded below - instead of showing the embedded video, all I see is a small red rectangle with a "play" button in it. If I press the play button, the video starts, but shows within the extremely small rectangle and I cannot watch it.

This is not so when I use Edge or Chrome, as shown on the second image uploaded below, showing the exact same webpage (the address is https://levski.bg/video/%f0%9f%94%b5-%d0%bb%d0%b5%d0%b2%d1%81%d0%ba%d0%b8-31-%d0%b1%d0%b5%d1%80%d0%be%d0%b5-%d0%b3%d0%be%d0%bb%d0%be%d0%b2%d0%b5-%d0%b5%d0%bc%d0%be%d1%86%d0%b8%d0%b8-%d1%80%d0%b5%d0%bf%d0%be/ ). The embedded video is clearly seen in its full size within the page, and when I click the play button it starts showing the video normally within the webpage without leaving the site and sending me to youtube, for example.

My question is, what is wrong and what can I do to start seeing the embedded videos normally again?

Thank you, Georgy Ganev

My passwords are apparently lost today after updating Firefox.

What went wrong? How could that happen? Why, Why Why?

Anyway to get them back? Are they hidden somewhere?

Anyone else suffering from this update too?

Any help or insights as to why would be greatly appreciated.

I have no idea how 100k people can review an extension labeled ICLOUD PW EXTENSION and you guys can't either remove it for the scam it is or show it has your approval as an extension up to FireFox security standards. 2.7 stars 100k reviews looks like a scam. Simply my feedback. Can't tell if I should trust so I'll never trust it until it's sufficient enough.

Two QNAP NAS displayed readable web pages this morning. Early afternoon I updated Firefox with a reset and the admin pages on both servers are unusable. How can I roll back Firefox or recover the earlier version?

When I use on line banking and I want to look at a check, I can not get Firefox to render a check image. Also I downloaded tickets to an event and FF would not render the Q-code on the tickets. I what to know what settings to change in order to do online banking. BTW it works in Chromium Browser, but I do not use it and have little knowledge about Chromium, I just have it on my laptop for troubleshooting.

I restarted my computer and Firefox has deleted my profile, including all bookmarks, settings, history, and add-ons. I had to make a new account using this email and google account which is the same email and google account I had on my old profile. Is there any way to retrieve my old profile?
