Firefox Community Forum

Hello,

When I try to visit a specific journal site that requires authentication, the browser automatically redirects me to an authentication page that I have used before. This is very annoying because every time I click a link to the journal, I’m sent to the other portal and can’t access the article. I want to stress that I haven’t installed any add‑on that would cause this redirection. I think I did that myself manually but I have no idea how. I’ve already deleted the cookies for both sites, but nothing has changed. I hope that makes sense, it’s a bit difficult to explain.

I'm using firefox 147.0, on mac Tahoe 26.2.

Thanks for the help !

On my MacBook Pro laptop, when I minimize a Firefox tab I cannot access other apps on the laptop. I can see them, but they do not respond to a click on them until I unminimize a Firefox tab.

No matter what I can not get this site from my favorite author to load. https://maxallancollins.com/ It use to work just fine. I have tried all the tricks when searching for "The page isn’t redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete.This problem can sometimes be caused by disabling or refusing to accept cookies."

I have deleted cookies, done a refresh, and done a new firefox still nothing. The page opens in Chrome. Any ideas? Thanks in advance.

For clarity, I am based in the UK trying to shop from the co-op supermarket which is based in the UK.

I am getting an access denied message with shop.coop.co.uk, but not with any other UK online shopping site.

I have tried all the usual suggestions like reboot, clear cache, remove proxy, and I do not have VPN.

I have downloaded the html of the message, and taken a screenshot of it as shown below. Looking into the html, there are references to Incapsula, which may suggest where the problem lies?

This problem started when I had to change my Virgin Media hub from Super Hub 2 to Hub 4 around July last year.

One suggestion that is often made is to delete cookies. However it is not clear which cookies may be relevant.

Any ideas on how to identify the source of this issue will be most welcome.

This has worked for me for years. It just began a few days ago when I tried to login and look at my new auto insurance policy. I've cleared the cache/cookies to no avail. I can access the web site with Edge (yuk)

Hi,

I have a personal bar with folders. When I click on a link in a folder, the folder automatically closes and if I want to open another link in the same folder, I have to reopen the folder. Is there a way to leave the folder open like Edge and Opera do?

Thanks Franky

REPEATING IMAGES involving . Macbook Air M4 Tahoe 26.2

When sliding from the primary Mac screen to another on the same computer the Firefox image (and ONLY that image) is duplicated on each additional screen image loaded making the use of multiple screens virtually useless.

Every time I try to use my camera or microphone on some websites from on firefox it says can't detect camera or microphone? It doesn't show up with the 'allow this website to access your camera/ microphone' pop up it does with other websites. I went into permissions and manually changed it myself and it said it still couldn't detect the camera/ microphone

I am trying to access certain HTTPS website and some of them show PR_CONNECT_RESET_ERROR in Firefox. This error is not present in Edge or Chrome. Any ideas on what could be the problem?

An error occurred during a connection to delta-executorr.com. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.

Here's what I've tried (none of these works):

   DNS over HTTPS turned off
   Uninstall all add-ons
   Reinstall Firefox
   Create new profile and set it as default
   Delete/rename certs.db in the Firefox profiles folder. 

I'm tired fixing errors which become more complex and solutions are written for people who have the time an knowledge to waste fixing these constant issues in FIREFOX, Time to change browser.

I don't know if this is relevant but one of the website that does not work is https://delta-executorr.com/

When attempting to sign in to my social security account I get the following message: Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

Hi, I’ve been experiencing slow startup times in Firefox, especially when I have my Time calculator web app open. The browser takes longer to load and sometimes becomes unresponsive.

I’ve tried disabling extensions and changing my home page, but the issue persists. Are there any specific settings or troubleshooting steps in Firefox that can help improve performance when using online calculators like this?

Any guidance or tips would be greatly appreciated. Thanks!

I had around 3000 tabs open I closed the browser completely today. Normally when I reopen firefox all those tabs were appearing still. This time none of the tabs restored I can see tabs in history part namede 19.01.2026 although not all my tabs are there. When ever I try to reload them from the restore history part; firefox doesnt reply and doesnt take the command.

Whenever a Firefox extension connects to a particular native application for the first time, a dialog opens that looks like the attached.

I've pressed "cancel" on this prompt.

Where are the "privacy settings" I can use to revert this ? Nothing in the "Privacy & Security" section looks like it, and there's nothing in the "about:extensions" sections either.

Lorsque j'essaie d'enregistrer une page dans un onglet, cliquer sur l'icône en forme d'étoile crée bien le lien, mais il s'affiche dans je ne sais quel onglet !!!. Il faut pourvoir le retrouver pour le mettre à la bonne place !!! Je souhaiterais pouvoir enregistrer la page où je le souhaite et créer un nouvel onglet au besoin.

When I try to save a page to a tab, clicking the star icon creates the link, but it opens in some unknown tab! I have to find it to put it in the right place! I would like to be able to save the page wherever I want and create a new tab if needed.
