Hello, After installing Firerfox on a new computer and some use of firefox the browser cannot find queerie's any more. Refreshing via 'Help' and 'More problem solutions help until after restarting the computer. Than again nothing is found. Microsoft edge can find things an other computers as well. Is there a reason why this happens and what can I do to solve it? Please your help. grtz Jan

I have four active Firefox windows, each with quite a few tabs. I have been closing and re-opening Firefox with no issue until today. Earlier this week I updated my Mac OS to Ventura 13.5, and Firefox was still operating normally after the installation (closing and re-opening with all windows and tabs intact).

Today however, when I restarted Firefox, no windows opened automatically. I closed and restarted a few times, and finally one window opened intact; however the other three windows (still dispalyed on the "Windows" menu) refuse to open. When I look at my Firefox app on my iPhone, it also shows all the tabs intact.

What can I do to get these to open? I am running Firefox version 115.0.3.

When trying to access a business web site I get: Logo

Access Denied

You do not have sufficient rights to access the requested location.

How do I fix this?

Hello there, I'm getting following warnings when I set report-to directive.

Content-Security-Policy: Couldn’t process unknown directive ‘report-to’ Content-Security-Policy: This site (http://puvipavan.local) has a Report-Only policy without a report URI. CSP will not block and cannot report violations of this policy.

These are the passed headers:

Am I missing something? I'm using the latest version of Firefox as of July-31-2023(115.0.3 (64-bit))

Hey every time i go to Facebook it keeps going super slow and continues to display the prompt bar where it says this page is slowing your browser down. to speed up your browser stop this page.... well its every single page. and this is happening to me on a couple of computers. I have cleared cache and cookies. I've turned off enhanced tracking. I've also tried opening in a private window and still the same thing.

https://forum.skylords.eu/uploads/stronghold_bombardment.mp4 This file can not be played with error message "Video can't be played because the file is corrupt.", and there is not even an option to download the file. Same file works fine in Chrome, Edge, VLC media player, ...

Their homepage says - "Firefox’s most recent update (v.115) is having issues playing the livestream. NPR Digital and Firefox have stated they are investigating the issue. In the meantime, we recommend listening with another browser (e.g. Chrome) or device (e.g. mobile app)." Will there be a fix???

Since the last upgrade Firefox regularly crashes. It becomes very slow then none of my tabs I may have open will load. Task manager tells me I have up to 27 firefox items running sometimes using huge amounts of CPU

I'm getting the message Device simulation changes require a reload to fully apply. Automatic reloads are disabled by default to avoid losing any changes in DevTools. You can enable reloading via the Settings menu.

I've looked through all the settings, searched for reload and still found no way to enable this. Googling it brings up answers from years ago that are clearly out of date. Where can I currently find this setting?

After removing elements from a website with another add-on, I'm left with a considerable white gap at the top.

I can manually change (pointless) the margin-top property to -100px, but how do I do this with the Stylus add-on?

Stylus doesn't like negative values:

margin-top -100px

10:20 Expected "{" but found "-100px".

Is there a lighter/simpler alternative to Stylus?

I think my firefox is infected in some way. I am constantly getting phishing pop-ups on the lower right hand corner of my screen when using the Firefox browser. They claim to be from McAfee, Windows and other legitimate places and tell me things like viruses have been detected, but scans of my computer do not detect any. They all come from something called 5qlql.azure.net or something similar to that.

My computer recently crashed. The technician that restored my computer downloaded a different version of Firefox . The version I had before had a sidebar with all of my bookmarks. The version I have now shows some the bookmarks across the top of the screen. I would like to have the other version. kfm1939@att.net Please help. Ken

Hi I have re-installed my Windows and all data have been backed up in my Firefox account. I have a problem with history and bookmarks which are not restored in my new windows but my password restored.
