Fórum podpory Firefox

Hi all. I've been using Firefox for years on my Mac. It's my browser of choice.

A couple of days ago, my Mac installed an OS update (v13.5.2). After the reboot, I opened Firefox and discovered that it, too, had installed an update (v117.0). But when I got into Gmail and tried to turn on desktop notifications, it said this:

Note: Notifications have been disabled in this browser.

And it's right--no other sites are sending me their usual notifications, either.

My problem is, I can't figure out why notifications are disabled in Firefox suddenly. I didn't disable them. I've tried clicking the lock on gmail's site and setting its permissions to allow notifications, but they aren't coming. I've checked my Mac's preferences, and Firefox has notifications enabled there, as usual. Gmail works fine on Chrome--notifications are working. I've tried reinstalling Firefox--no change. I've tried running Firefox in troubleshooting mode--no joy. Other sites aren't even asking for permission to send notifications. Like Gmail, they appear to believe notifications are disabled in the browser.

I've searched the web for solutions, but I can't find one that tells me where the enable/disable switch is. Can some kind soul please help me out here?

Thank you SO MUCH in advance!!

Hello, once again the function of restoring recently closed windows has stopped working, it is displayed in gray and you cannot enter it I usually work on two or three windows at the same time and this function usually works, but I can't use it for the second or third time. Can I recover closed windows? I will be grateful for your help Best regards, Paweł U

Hiya. I usually have a fairly large number of tabs open on the browser. I use the Panorama View add-on for tab management. Usually this means that on any given container I have about 10-20 tabs open for a total of some 300 odd tabs. The nice thing is that Firefox doesn't usually load all my tabs so this works out for me. Recently however something weird's been going on and Firefox just refreshed ALL my tabs across all the containers. This kills my performance completely, especially given a fair number of tabs are just random youtube links. When all my tabs are open Firefox eats up like 25 GB of RAM, which is understandably not great.

I tried refreshing Firefox to no avail. Is there any way to stop this constant loading of all tabs?

I hope this applies here. I tried using the "-p" command fro Librewolf. Wiped out my sessions and settings.

Is there a way to do this in Firefox and or Librewolf?

This is a recurring problem. I have just been on to Vodafone who have tweaked my router as my speeds, download and upload, were very erratic, and upload speed often zero so connections failed. Sometimes my phone speeds were similar but not always. The Speedtest by Oopla desktop app also showed erratic results but often when they were OK the web-based test on Firefox was much worse, with upload speed zero. When I started this Firefox showed upload speed zero. Now Firefox shows upload 18Mbps. This variability keeps happening and is driving me spare, as even emails often fail to go through - I use Thunderbird. I shall see how things go tomorrow and tell you how it is going.

Hi! I was wondering why nearly every single page these days opens to the message :

"400 Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. Apache Server at canvas.instructure.com Port 80"

Nearly every link I click on a website refuses to open! It has become impossible to do school work on this browser because I can't open any link on my school website, and nearly every website struggles to open except from google. I know the links work because I copy/paste them into Google Chrome and they open immediately. Truth be told I prefer Firefox and would much rather keep using this browser! I also can't find an update for Firefox so I believe my Browser is up to date (and I know my laptop is up to date and virus free). Is there a fix coming soon? Or a setting I can change to be able to open links? Classes start this week and I'm stuck!

Thanks for your help!

I want to navigate on search results using the keyboard. I could use tab but it suggests all interactive elements such as news, images, books, videos, search settings and etc one by one. I want to press something and make active first result, then second. If such hotkeys are not provided, maybe there are any extensions with similar functionality?

When a bookmark is made, there is no option anywhere to add tags using windows 11 - I had no problem with tagging bookmarks using Firefox in windows 10, but that option is not showing up for me in windows 11. I have refreshed Firefox with no success to try to correct this situation - thanks in advance for any help you may provide – del

Hi, I'm having this problem of videos not playing in some websites for a long time now, not even sure how long anymore. It started on Twitter, where I get the error message "The media could not be played". Some time after I got it on Instagram where I get the message "Sorry, we're having trouble with playing this video. Learn More". More recently I subscribed to the Nebula service and got a message there as well "The media could not be loaded". Differently from other people I don't have this problem on Youtube, over there everything has always been fine. I have tried every workaround on this, I have seen many tutorial videos and articles and tried everything and nothing worked. Running on Windows 10

Some things I have tried: -cleared cookies and cache; -disabled all add-ons, removed them even; -checked if firefox was updated; -checked if graphics card drives were updated; -opened websites on incognito mode, nothing changed there; -started Firefox in troubleshoot mode, nothing changed there; -disabled graphics hardware acceleration in Firefox; -enabled autoplay; -reset firefox; -changed my pc actually, installed firefox, got the error and reset firefox again;

Could anyone help me with this? Is this normal?

I am unable to login to my Prescription provider's website (which I do every day). Problem started Sunday and still persists.

I am able to login using Chrome, so I know the website is working properly.

Help - I DO NOT want to use Chrome.

Not sure when it started but nearly every attempt to play Youtube videos results in the video freezing after about 1/2 second while audio continues, then the video jumps forward randomly before freezing again. Have reloaded, restarted, cleared history, cookies, etc, and nothing helps. Mean time Chrome plays the videos flawlessly. This is a recent problem with FF and needs fixing badly as it will just not go away.

As shown in the image the tags field is missing from my bookmarks editor. Any idea how this could happen? Any options or about:config options I should check?

I've attached troubleshooting information. I'm on Arch Linux and I have two other Arch machines on the same Firefox version (Arch Linux Package) that do not exhibit this behavior.

Hello!

I recently got a new computer with Windows 11 freshly installed. I downloaded Firefox, went to take a screenshot, and the usual shortcut of Ctrl + Shift + S does not work. I can right click and Take a Screenshot, and I can use other Ctrl + Shift shortcuts, like Ctrl + Shift + T to reopen closed tabs. The only one that doesn't work is screenshots. I can also put Screenshots in my top row Toolbar and use it, just not the keyboard shortcut.

I refreshed Firefox, uninstalled and reinstalled Firefox, as well as checked the about:config extensions.screenshots.disabled preference. It has been set to false, so I have set it to true and false again hoping it would "reset" it but nothing. Thank you!

Using arch's latest version. I recently upgraded my firefox version to 117.0, and can't play any videos from different sources.

The image freezes and is in an eternal buffering state.

I tried downgrading to 116.0 and 115.0, and the issue persists, so it doesn't seem to be related to the latest Firefox version.

So far, I've confirmed the same issue in YouTube and Twitch.

On Twitch, the videos are super laggy. The image freezes, then moves to a different scene, freezes again, and then the same thing over and over.

On YouTube, it always shows as loading. If I try to move it to play a different time in the video, it works for half a second and then freezes again.

The issue still occurs if I try incognito mode, troubleshoot mode and refreshing Firefox. I already tried disabling hardware acceleration (https://support.mozilla.org/en-US/questions/1206076) and have no more ideas or options.

Thanks in advance!

From a security / QOL pov I'd like to disable an extension on some websites, and was wondering if there were any methods to do this?

I searched this question first through reddit and the support site and found similar questions with no updates asked between 4-6 years ago, wondering if there's been a method implemented yet or if it's still not possible.

Thanks!

This problem started yesterday and I cant seem to fix it where youtube is too wide for my screen without any indicator on the top of my screen saying that its zoomed in and I cant watch any videos fullscreen. This glitch isn't a problem on any other websites. I tried opening and closing the browser, I tried restarting my computer tried clearing my cache and cookies and I tried using different accounts but none of them seem to fix the problem!

Few days ago, some of our clients and few (not all) internal PC are get stucked on a PR_CONNECT_RESET_ERROR on our website. Only on 117 windows version (118 developer version and 119 nightly seems ok). We tried to repair firefox, it works on 95% but we can't ask our client to do this. It works on Chrome & Edge.

We running out of ideas : - we only accept TLS 1.2 / 1.3 - checking CSP - Both IIS and Apache are not working - Firewall are not blocking

I ran a loghttps://pastebin.com/jydVHHs0 of playing a youtube video mediaencoder? not sure if encoding issue or something else

The videos take a long time to play. I upgraded my system recently and was removing and reinstalling audio-related utilities with DNF.

Keep getting this on a number of websites. Most of them I have used for years. Can't give the websites as there are too many but some are pitchsidemanager.com, hattrick.org, skysports.com and sportinglife.com . Just four of at least 14 give the Hmm. We’re having trouble finding that site message. I use No Proxy and have my anti-virus turned off when I get the message. I have tried various other proxy settings but the same thing happens. The thing is that I have to keep refreshing the page until it does actually connect and that can take a good few minutes. Sometimes I have to restart the browser. Why is this happening since the last few updates?
