When I try to connect to my email provider fredcazstanton@aol.com I click on my Firefox browser and type in AOL.com however; there are may sign ins and I can get 'breaking news' etc but cannot get into my emails. All I wish for is to open my computer, go the first opening page, select the short cut and get straight in to my emails can you help please??

If you're unable to access your website on Firefox desktop, try these steps: - Clear cache and cookies in Firefox to remove any outdated or corrupted data. - Disable extensions or test in Safe Mode to check for conflicts. - Ensure HTTPS usage and verify there are no mixed content issues (HTTP elements on an HTTPS site), as Firefox may block them.

I've used Google Maps in Firefox for years on a Surface PC. Over the past couple of weeks, I've found that Google Maps will select a route or routes, but they don't show up (highlighted in blue) on the page. What's happened? Is there a fix...?

Many thanks.

Best,

I had this issue a few months ago but it then seemed to resolve itself. Now it's back.

I use passkey on a few sites like Google, Youtube, Hubspot... every time I attempt to use passkey on such sites Firefox locks up and I can't select anything on the page, a different tab. It just completely locks up and I have to restart it.

I always deselect cookies.

I don't have this issue on Safari so it is the only way I have to deal with this issue.

Every document like the below one does not display in firefox esr 115:

I get an empty pdf viewer frame. Also the debugger shows the following error;

Uncaught TypeError: Promise.withResolvers is not a function

Is there some way to overcome this problem? a future release of firefox esr?

Warning: Potential Security Risk Ahead Firefox detected a potential security threat and did not continue to 172.18.100.25. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

Numerous sites, most recently Etsy, will not give me access. The message is always this or some variation: "We detected unusual activity from your device or network. Reasons may include: Rapid taps or clicks. JavaScript disabled or not working. Automated (bot) activity on your network (IP 71.217.57.171) Use of developer or inspection tools."

This happens even if I disable Ublock Origin. The only other extensions I have are 1Password, Zoom and Undo close tab. How do I fix this? The problem does not exist if I use a different browser. It is VERY frustrating!

Even though the custom folder for "downloads" has been set firefox keeps creating new one in the home folder. Nothing I've tried to do helped. From the bug reports I see this problem exists in the firefox at least for 15 years! I can't believe it is still not fixed. That's kind of behavior minor enough for the developers to take care of and major enough for the users to give up and switch browsers if it is not fixed. Crazy.

I am trying to implement the below with fire fox containers however I am not sure how you disable the option to clear cookies per container ?

See below.

I also use this extension in order to have quick access to all of my Google Voice numbers. I created a new container for each Google Voice number I own. I then logged in to the appropriate account for each container and disabled the option to clear my cookies upon exit. Today, I can launch Firefox, select the container titled with the number I want to use, and immediately place or accept a call via my desktop. I can close the browser completely when I am done. I also changed the icon and name to reflect this purpose. This has been most beneficial when I have been on a call with a financial institution and they want to call me back at a specific number which they have on file. Opening the browser and being immediately ready is better than connecting to Google Voice; opening my password manager; inserting my credentials; providing 2FA; accessing the account; allowing my microphone; and accepting the call. My device is encrypted and protected with a strong password in the event it is stolen.

Hi,

For the last 2 weeks or so Roboform task bar has not displayed on firefox. It works perfectly OK with Edge. I tried uninstalling and then reinstalling roboform without closing roboform and miraculously the task bar appeared attached to the bottom of the screen for the duration of the session. I thought the problem was fixed however, when I next restarted the PC it was again not present. Any ideas how to fix this as I do not wish to use edge.

When I used a VPN I got this message

   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

How do I check?

Or does Mozilla have a vpn I can use?

Thank you Greg
