Hello, I recently used my MacBook Air to connect with a projector for a classroom presentation. The presentation was using Google Slides. I adjusted the settings to optimize the presentation--setting the navigation and bookmarks bars to hide when in full screen.

I normally use my Firefox browser in full screen mode, but have the navigation bar and tool bar visible.

I cannot figure out how to undo what I did so that my navigation bar and toolbar are visible again when I am in full screen mode. Indeed, when I move the pointer to the top of the screen to make the navigation bar and toolbar visible, I cannot move the pointer back to the navigation bar or toolbar without it disappearing again. Essentially, I need to undo full screen mode.

Thanks, jch

In the Microsoft Store there are all these updates for video extensions like "AV1 Video Extension". Should I be doing these updates? Do they make any difference to streaming video on the Firefox Browser?

A few days ago Ubuntu (22.04 LTS) showed me a message saying I can upgrade my OS (or something along those lines). I click on agree (any button that would let me proceed) and the upgrade took place (without restarting). Along with the upgrade Firefox was also updated to its latest version at the time (119.0). Since then, videos on Twitter play but without sound. On some other websites also none of the videos play. On YouTube, Firefox shows me a message saying "To play video, you may need to install the required video codecs" but the videos play fine; I haven't tried other websites but I assume all would have some issues. Google Chrome however doesn't have this issue and all videos play without any issues.

Note that I have not restarted my computer since the upgrade. I doubt this could be an issue but please let me know if you think this could be the issue.

I did the followings and restarted Firefox but none have worked so far for Twitter and some other random websites that I come across, but they resolved the issue for YouTube and now YouTube videos play, although I still get that codec message at the top of the tab:

sudo apt-get install ffmpeg sudo apt install ubuntu-restricted-extras sudo apt install libavcodec-extra

Someone told me this is because the default Firefox on Ubuntu 22 comes as a snap package and I should install the APT package manually instead so that it works. I prefer not to do this because I have lots of tabs open and have manually changed lots of the settings (including in about:config) that I want to preserve. I would also like to preserve the history of visited websites and keep the current cookies (don't really want to keep entering username/password on the same websites again). So the best way for me is to fix the issue for the default Firefox on Ubuntu 22.

Could you help me figure out what I should do to fix this issue?

I accidentally hid the menu bar and toolbars (with an accidental keyboard shortcut, I think), and when I re-enabled them, now the tab bar is above the location bar instead of right above the content windows. How do I move it back? I can't find the "browser.tabs.onTop" setting in about:config, or any check box in the View menu, settings, etc.

I'm using Firefox 119.0.1 on Ubuntu Linux.

Thanks!

Dear Friends,

Trust all is well...

PLEEZE put an end to this mystery. Can you BLOCK YOUTUBE ADS or not? If so, how is that accomplished.

Many of the extension are not safe even dangerous to use.

Thank You!

Best, Ralph

Since pretty much the beginning of the internet, pop-ups were deemed a significant annoyance, so much so it diminished and ruined the users’ browsing experience and significantly reduced efficiencies. Hence the addition of pop-up blocking settings to all browsers long ago.

However, for some unknown reason Firefox gives Google a free pass and allows their “sign-in” pop-up that pop-ups seemingly on every website you visit where you then have to then manually close the pop-up on pretty much every single website you visit - even though you have the pop-up blocker setting on ( and the only way to turn off a pop-up blocker is to specifically add a website to allow for pop-ups).

This is absolutely horrible and not acceptable. If you have the pop-up setting on, no pop-up should be allowed to get through no matter what it is or the source. If you allow one pop-up to continue then you should be allowing hundreds of thousands of other pop-ups as well. But you wouldn’t as you know this would be unacceptable, but again, somehow Firefox allows Google’s pop-up to go through and it pop-ups on pretty much every single website you visit.

Note that I selected Privacy and Security Setting as the "topic" above as that is were Firefox has it's pop-up setting (and where you can add exceptions to allow pop-ups for specific websites)

I've been trying to export my bookmarks to an external hard drive so that if something should happen to my computer I have a file of them. I'm using Windows 11.

When I export the bookmarks as an HTML file, it saves OLD bookmarks from a few years ago, not the current ones. I know this because when I go to my external hard drive and click on the file and open it up it shows the old bookmarks.

I have no idea why this is happening. Can anyone help me? Thanks.

I decided to migrate from chrome to firefox, sadly, my experience has been faced with random slow downs or partial loads even on a fresh install. It's weird but it seems that at random times some websites will refuse to fully load or even start loading, it appears that the app is just hanging. This is usually fixed after several refreshes. Oddly enough, even on a fresh install, if I attempt to load up the same website while in private browsing, it loads right away, again this is consistent even on a fresh install, the attached image was an attempt to load youtube after signing in on a fresh install without add-ons, I tried loading up youtube in private and it worked right away. Chrome wasn't presenting this problem on my computer for years. Any ideas? My computer specs are high enough where they shouldn't matter. I'm running an AMD GPU (7900 XTX) but I haven't found any know issues regarding these, to even discard that, I disabled hardware acceleration, but the issue persisted. Running up to date windows 10, installing latest version of firefox.

hi, well I deleted and distrusted a certificate. now I'm trying to import the same certificate but it doesn't work. when i add the certificate i does not show anything on the certs list.

Whenever I open the find bar while deleting the phrases and words, it shows the one word highlighted or its phrase highlighted on the find bar whenever I reopen after deleting the phrases and words. I need help for this ?

Until recently, when I entered a search request, I only received sponsored links which covered part of the screen. However now the list of sponsored links has grown so much that I am having to scroll through several screen pages before getting to the lings to the actual websites that I am looking for.

The number of sponsored links has grown out of all proportion and means that I am waisting a lot of time scrolling through items that are of no interest to me whatsoever. As an example, I recently made an enquiry about a medical condition and an Amazon sponsored links offered me a good deal on selling me that same medical condition!!!!

How can I or Mozilla reduce the high level of sponsored links. If it cannot be done then I will need to move to another browser.

I recently downloaded Firefox and attempted to create an account- TWICE! When I attempt to use the Firefox account/ app I get a page saying I should download Firefox! I ALREADY DID!!!- TWICE. Have an application support technician check it out and FIX IT!

If I can't resolve this issue within a week I'll give up & quit.

My Windows Task Scheduler contains an entry called "Firefox Default Browser Agent". If I delete it, it returns. If I disable it, it re-enables itself. Can't be modified either. How do I turn it off permanently?

I already have telemetry and automatic updates both turned off.

In about:config default-browser-agent.enabled is set to false
