I haven't been able to move tabs around for days. Not since I tried to take some 'out' to make a new window, and Firefox straight up crashed ...repeatedly. After I gave up, I noticed the tabs no longer moved.

I ignored it a few days, but its frankly very annoying! I checked for answers & found an old post from 5 yrs ago here & followed the advice. Or I tried to, but when I checked "browser.tabs.allowTabDetach" in "about:config" it was already set to "true". I even toggled it a few times (I even tried to see if it would move when set to false! ...counterintuitive, but I figured it was worth a try?)

Anyhow "browser.tabs.allowTabDetach" is still set to true, and I'm not about to go monkeying with all that :\

(fair warning, while I know how to alter a config under clear instructions ...my experience with such things starts and ends with the config files for Stardew Valley mods)

advice I found, which doesn't work/apply??- https://support.mozilla.org/en-US/questions/1302126

Autoplay (of video SOUND) is always set to OFF except in a few cases where it is set to ALWAYS ASK FIRST. Facebook reels often ignore this setting. How can I stop it. The same phone setting on my Galaxy phone covers both AUDIO and INCOMING PHONE CALLS (ringing). If I mute my phone I cannot hear it ring. If I don't Facbook blasts the entire room ... when it was never supposed to to do via the settings.

I wish to get rid of your logo when I go into Firefox and it appears on my blank screen. Very annoying. I use Firefox as my browers and have been very happy with it. I just want to get rid of the logo everytime I go into firefox. Thanks for any information you can give me.

I KEEP CHOSING "ORGINAL ACCOUNT". IT KEEPS PROMPTING ME TO ""SIGN IN"". BUT IT DOESN'T GIVE ME ANY PLACE TO SIGN IN AT. THE BROWSER IS DEAD. I'VE BEEN WORKING ON THE PROBLEM FOR HOURS. MAYBE IT IS A PERMISSION, A STARTUP SETTING, THIS LAPTOP, WINDOWS 11 OR A COMBINATION OF ALL THESE THINGS. I DOWNLOADED "BRAVE" BROWSER AND IT WORKS FINE. I DON'T KNOW WHAT TO DO. I CAN LOG INTO MICROSOFT, GOOGLE, BUT MOZILLA IS LIKE, REALLY REALLY DEAD.

ANY HELP IS OF COURSE APPRECTIATED. PHONE: [edited] MIKE

So whenever I click on new tabs, it always leads to a redirect notice asking me to confirm if I want to open those tabs.

I want it so that I don't get these notices, but the links I click on just open automatically. I have tried the following settings in about:config based on a few threads online:

accessibility.blockautorefresh

network.http.redirection-limit

A few other settings to that I have turned on and off but no difference.

A lot of the websites are also confusing because they seem to want to turn redirects ON rather than off, so potentially I am struggling to follow the correct information.

Any help appreciated.

The Alt-<number> keyboard shortcut is used to switch between tabs. However, the key event used to switch a tab seems to also propagate down to the content itself. This creates weird interactions:

- I switch to third tab - The web page running in the third tab actually uses Alt-3 to do something - After switching tabs the web page does something unexpected because the browser chrome didn't swallow the event during its tab-switching procedure.

The most irritating candidate seems to be XenForo forum software that uses Alt-<number> to go to different sections in its menubar. For example, alt-4 seems to open a search page and going there provides no new entry in the browser history. So, if I've tab-opened the forum to display new posts and then later I switch to it using Alt-4, it makes the content go to its search panel with no way to go back to new posts. Ironically, switching _away_ from the tab 4 does not register to the content so I can't even use the forum's own keyboard shortcuts to navigate back to new posts section or any other section. Having the forum in tab X will only ever let the forum see Alt-X and nothing else.

This all stems from the fact that Firefox lets the initial tab-switching key event through whereas I think it shouldn't. It maybe should if the corresponding tab is already active but it certainly shouldn't when a tab-switch actually occurs.

I've obviously disabled the content's capability to override keyboard shortcuts but it doesn't help in this because the content is not overriding anything: it seems to be just listening to a keyboard event that it shouldn't see.

Did I miss some option in about:config or do others see this as well?

Beginning today, I suddenly cannot access numerous websites when I use Mozilla Firefox 151.0.2. Examples include Amazon, and Google, et al. Attempts to do so consistently fail at the point of performing a TLS handshake, when I am advised that "secure connection failed". Kindly refer to the attached screenshots. I have no difficulty whatsoever accessing the same websites when I use other browsers, such as Google Chrome and MS Edge. I previously had Mozilla Firefox enabled as my default browser, but I have had to change this, given these "challenges". Please advise how I can fix this. Best regards and many thanks.

When following a link from a news website I keep getting this message - Secure Connection Failed - The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. It loads on my iPhone and other browsers using the same link. What setting do I need to address to get this to stop?

Current Setup: OS: Windows 11 Home (10.0.26200) Firefox Version: 151.0.2 (Build ID: 20260525130955)

Issue:

• Firefox suddenly is unable to connect to any wesbite
• All attempts to browse result in the "Secure Connection Failed" screen
• All other browsers function fine with no network connectivity issues

Exact Display Text:

Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Attempted Fixes / Things Confirmed:

• Everything mentioned in: Firefox can't load websites but other browsers can

• Relevant about:config values:

* * security.enterprise_roots.enabled -> True

• * security.ssl.enable_ocsp_must_staple -> True
• * security.ssl.enable_ocsp_stapling -> True
• * security.tls.version.max -> 4
• * security.tls.version.min -> 3

• System locale and timezone are correct
• DNS over HTTPS is set to OFF
• HTTPS-Only Mode is set to Don't enable HTTPS-Only Mode
• Restarting in Troubleshooting Mode
• Disabling the Anti-Virus (including the device Firewall)
• Disabling any VPNs or network proxies
• Clearing cache and browsing history
• Clearing certificates from the Certificate Manager in Settings
• Attempting connection with a newly created profile
• Clearing the cert9.db file for Firefox to reset certificate information
• Refreshing Firefox (resetting it completely)
• Uninstalling and reinstalling Firefox (after clearing all Mozilla related %appdata% folders)

Observations

• When trying to mess with the device timezone and see if changing it back to the correct one would "reset" something, after a few attempts of starting Firefox in the wrong timezone and then restarting it after changing to the correct one, for a single session, I was able to browse normally again. I closed Firefox to see if the problem was fixed but it went back to the "Secure Connection Failed" page. Was unable to reproduce the same behavior.

• Tried installing a portable version of Firefox (151.0.3) from Firefox Portable .

After installation, the first session works perfectly fine but after I close the session and restart Firefox, it gives the same "Secure Connection Failed" message.

• * Reinstalling the portable version in the folder, gives the error from the get-go, not even the initial post-installation session works but installing in a different folder works fine for the first session but all subsequent restarts (sessions) of the browser give the same error.

At some point recently, a 'Profiles tab has appeared in my menu bar. Presumably this arrived during an update. I don't want it, keep accidentally clicking on it instead of bookmarks & want it gone. How do I remove it?

Mozilla has been bragging about the free built-in Firefox VPN for months now. I still don't see it. I'm on the latest release (151.0.3) but I don't see any way to access it. I know they've said it would be a phased rollout but it's been a long time coming already. Am I doing somethin wrong?

cut and paste not working on one box on ebay listing page!

ebay sell an item. opened page appears with boxes of which one is called description. This week, the cut and paste will no longer work on that box. It works on every other box on that page! Ebay say its not them.

My browser was recently updated to 150.0.2, and on the new launch page after update describing new features, it prompted me that the new free mozilla vpn was available to try. When I clicked on the link to follow the steps to set it up, it said to click the vpn icon in the toolbar, but I don't see that icon there. When I go to more tools -> customize toolbar to try to find that icon to add it back, it doesn't appear among the toolbar options. Is this something I still don't have access to because it's in a limited beta, or is there some other way I should be accessing this?
