After years of shopping online with Tesco using Firefox suddenly I can no longer log in to Tesco.com. Just get 'Access Denied. You do not have permission to access------etc' I am sure that this happened after the last update of Firefox ! Tesco say its not their problem and the problem is with my Firefox browser. Please advise.

I want to find to get rid of this or find the source of this so I can delete it.

In "about:policies" there are 2 Active Policies: "DisableTelemetry", and "DisableDefaultBrowserAgent" Also, in "about:policies" I'm not sure if it's related, but there is a long list of policies there too.

I can't seem to access one website that I used to visit daily: www.leftwinglock.com

I have no issue with any other site that I visit daily, and my co-workers are able to access that site so it is not down.

Is there something in my settings that is preventing me from viewing this site now?

Thanks.

When going to sites such as nbcnews.com/now or https://toronto.ctvnews.ca, A/V sync is off by about a second.

This appears to be due to the volume being muted when video playback starts. Unpausing the video leads to the video freezing for a very brief moment, then the A/V sync is clearly incorrect.

This can be replicated on YouTube by loading a video, muting the video (if not muted already), refreshing the page (F5), allowing the video to play, then unmuting the video. The sync will be incorrect.

If the audio is unmuted when the video play back starts, this does not appear to happen.

Following this article has no impact: https://support.mozilla.org/en-US/kb/performance-settings, nor does setting media.hardware-video-decoding.enabled to false.

This issue does not occur on Microsoft Edge.

What can I do to prevent Firefox from keeping me out of certain websites and showing this error message: Firefox Can’t Open This Page

Firefox has been crashing multiple times per day for several weeks now. It used to be fine, hardly ever crashing. I can't think of anything I'm doing differently since before the crashes started. I can only assume that it started after a specific Firefox update. I do have a lot of windows/tabs open at once, but that was never an issue in the past. Occasionally individual pages will crash, usually several at once. The entire software crashes all at once regularly as well. Sometimes the crash seems to cause other issues, such as my computer hanging up for a bit, or my monitors going blank and the graphics system seeming to reset, before Firefox actually crashes. I don't always get a crash report dialogue when the whole thing crashes.

I keep my Windows and Firefox up to date. I tried turning off hardware acceleration, but I think that might have made it worse so I turned it back on. I cleared the caches (which took well over five minutes), and ran speedyfox a few times. I exit Firefox through File > Exit whenever I need to restart or run other heavy software.

I can log into preply.com with Chrome and Edge, but always have problems with Firefox. I was able to log in once, but after that, I can't log back in.

Recently I had to reinstall Windows, and saw the opportunity to try getting this to work. Installed Firefox, but *before* I logged into Mozilla Sync (so I'm working with a 100% fresh installation with no history of having Firefox installed) I tried to log into preply.com. It worked. Then, I log myself out and try to log in again, and once more, I can't log back in. I'm attaching a screenshot of what I see when I try. Please note -- I have no bookmarks, no extensions, no addons, no browser history. Everything is tabula rasa.

I found this page:

https://support.mozilla.org/en-US/kb/fix-login-issues-on-websites-require-passwords

and followed it to the letter, meticulously, to no avail. I still can't log into the site with Firefox. Chrome and Edge, yes. Firefox no. I only have Edge because I can't uninstall it. I only have Chrome for situations like this, where Firefox doesn't work. Firefox is my main browser, and I really, really would like to figure out what's happening. I can't understand how this problem persists when the browser is freshly installed; I haven't imported one bit of data yet from my sync account.

Can someone more experienced than me please help?

Hi,

I lost all my bookmarks because I forgot my Firefox account password and didn't realize they were in the cloud (I thought they were stored locally). I don't have any bookmarks backups, but I did recently back up my Macbook via Time Machine. Would Time Machine be able to recover my previous bookmarks? If so, how?

Thank you.

I am on Firefox Developer Edition 120.0b9 (64-bit macOS). Using sites like whatismyip and whatismyipaddress, I am seeing that I have a VPN or Proxy enabled. When I use Chrome, I don't see this. I went through all the settings and turned off anything that could even remotely be related, and still get the same results. Does Firefox have a built in VPN that I am unaware of? Is there a way to turn it off?

I have Firefox as my browser on my laptop. Today I have been getting numerous pop-up messages from McAfee (which I do not have- I use a different web defense app) saying I need to renew my subscription or virus detected. Nothing I do gets rid of these pop-ups, which keep coming back (see example below) . How can I stop this from occurring? HELP!!

When I try to login to the Tesco website I get this message: Access Denied You don't have permission to access "http://www.tesco.com/account/login/en-GB?" on this server.

Reference #18.26cc19b8.1700669440.3c27026b

I have cleared History plus cookiies and site data and cached web content

But I'm still unable yo login to this site.

1. When I set "NEVER REMEMBER HISTORY" Firefox create an initial INVALID INITIAL http request.

GET /lipsum.html undefined <--------------------- HERE Host: myhost.com User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate, br DNT: 1 Sec-GPC: 1 Upgrade-Insecure-Requests: 1 Connection: keep-alive Sec-Fetch-Dest: document Sec-Fetch-Mode: navigate Sec-Fetch-Site: none Sec-Fetch-User: ?1 Pragma: no-cache Cache-Control: no-cache

3. This causes a NS_ERROR_NET_TIMEOUT_EXTERNAL

4. Firefox then immediately issues a 2nd HTTP Request, this time correctly.

GET /lipsum.html HTTP/1.1 <---------------------------- Host: myhost.com User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate DNT: 1 Sec-GPC: 1 Connection: keep-alive Upgrade-Insecure-Requests: 1 Pragma: no-cache Cache-Control: no-cache

I have a video of the behavior and a simple HTML file to test with. I can't upload either.

Other browsers and programs manage to use the web just fine, but lately, firefox is hanging for minutes at a time, spinning its wheels, when I try to do anything online. It happens multiple times per hour, for several minutes. No idea what is wrong. I tried everything firefox recommends. Nada. Anybuddy have a clue? About to go back to the darkside, chrome. This is maddening.

So I've scoured the Firefox community help and have done everything: disabled cookie auto-delete, make sure I have "always use private browsing mode" unchecked, make sure Firefox always saves logins/history/etc., have security set to "Standard," and have added exceptions to the Firefox security; yet, despite all this, I'm still getting logged out everytime I close the browser. I'm getting to my wit's end!

What else can be done to fix this? It's really frickin annoying having to sign back into everything, everytime I open Firefox. Thank you in advance.

Firefox just updated to version 120.0 I hadn't used youtube for a while. When I tried to play youtube videos none of them will play, only get a green screen with audio In troubleshooting mode they will play Refreshing firefox does not fix the problem

Help! I just installed the latest Firefox 120.0 and I have a huge problem:

I work a lot with the address bar. I type a few characters and choose a URL from my history that I need to work with, then modify that URL by typing or pasting, to get the address I need. Now, I can't do that. Either I accept the full URL suggested or I must type a completely new one. That's a huge obstacle for me. I absolutely need to work with, i.e. select and modify, URLs that I have previously visited.

Please tell me there is a way to do this!

I just updated to Firefox 120, and tried the new GPC setting (Tell websites not to sell or share my data). I ran into a problem when I went to the Xfinity community forums (https://forums.xfinity.com/) . It causes a banner on top showing they recognize the setting. There is an "X" in the corner, and some text that says "Hide this banner", but they are not active. Plus, I cannot make a new post or do a general reply (that weird forum software has both local replies to a particular post and general replies to the general thread.)

Is this a bug in Firefox, or a bug in their forum software? I attached a picture of the message it gives.

I'm having the exact same problem as what was originally mentioned in this post from 4 years ago.

The "chosen solution" was to exit firefox through the hamburger menu, which I find to be absolutely ridiculous. You mean to tell me that even though I close EVERY OTHER APPLICATION either using the "X" close button or a custom keybinding that I've set for my own personal convenience, firefox requires me to exit through a menu every time in order to make it behave the way I've told it to? No. Absolutely not. If I tell firefox that I don't want it to save my last session, that means I DON'T WANT IT TO SAVE MY LAST SESSION. If I've deselected the "open previous windows and tabs" option in the settings, then under no circumstances should it be trying to open my previous windows and tabs.

I've tried the suggestion to change the value of browser.sessionstore.max_resumed_crashes from 1 to 0. The problem persists, I assume because firefox considers being closed using the close button to be a "crash", which is interesting.

I the other suggestion further down in the thread was to set browser.sessionstore.resume_from_crash from true to false, which will prevent firefox from recovering a session from a crash. This is hardly an appropriate solution. I want firefox to resume my last session if there is a legitimate (key word LEGITIMATE) crash, because my session was closed against my will due to something that went wrong. Being able to recover my last session in such a situation is nice. I do not, however, want firefox to resume my last session when I explicitly closed the last session myself, which would be the difference between a crash recovery and restoring a previous session. If no crash occurred, I don't need a crash recovery, and aside from a crash, I don't want my previous session to be restored.

Are there any solutions to this at all? Because this is one of the biggest reasons why I stopped using firefox. I want to come back to firefox because everything else that's worth using is either dog shit, or Chromium-based (i.e. also dog shit). However, I find this broken feature to be somewhat of a security issue. If a bad actor somehow gains access to my system, I don't want him to be able to open firefox and have access to my last browser session because I closed firefox using a keyboard shortcut instead of closing it through a goddamned menu.
