Hello Mozilla, FireFox in my default browser, but since you last update to 150.0, now my outlook won't open the hyper links from e-mail with them. It worked just fine between the two before. Now I get a message " this operation has been cancelled due to restrictions in effect on this compute. Please contact your system administrator." I am the administrator! anybody else report this issue since? I've tried all the internet advised fixes of changing the regedit registers from FIREFOXhtml to just htmlfile, but no joy. Any help with this would be greatly appreciated. Kind Regards Edward England, UK

I'm using Firefox on Fedora 43 Linux, fully updated, and have it set up to use four desktops on the same monitor, using the Xfce DE and Compiz. For the last several months, any time I click in a link in Thunderbird, instead of switching to the desktop with Firefox on it, it pulls Firefox to Thunderbird's desktop and covers Thunderbird. This has continued through several updates of Firefox and at least one upgrade of Fedora. I don't know if Firefox or Xfce is the issue, but if it's Firefox, where do I look?

When I open email links in Firefox, it opens my mail app (proton) but not a new email message. I’ve been in contact with proton support and they said this is only an issue with Firefox and not other browsers. This take works fine on safari and brave on my end, so it seems like a Firefox specific issue. Is this a bug or is there a setting I can fix on my end?

When I click a link in Firefox sometimes it will open up the new window in Chrome, how can I stop this? I don't want to make Firefox my default browser, as I use Chrome for that.

bold textI have my Windows 11 and Firefox updated as of 4/3/2026. I have two ongoing problems with Firefox. 1. No link works. I keep getting redirected back to my original location. I have used your troubleshoot feature to restart, but it doesn't stay fixed. 2. I have AdBlock Plus Premium and everytime I close the browser it logs me out of my AdBlock account. It is a real irritating problem. I pay to have ads blocked and if I can't keep it from blocking unwanted ads, then I guess I will quit using Firefox.

Google browser keeps popping up in my browserwhen Firefox is my default browser in my setting and downloaded & installed from my Google playstore. I don't like Google and what it does but I feel trapped because I have so much important data on their Gmail and other Google apps. I am a senior with traumatic brain injury and have no tech knowledge or experience to have other options.

I'm a fairly heavy shortcuts user, and recently within the last couple weeks, they've stopped navigating to the intended page. When you click them the shortcuts and the iOS keyboard close, but the browser does not navigate. How can I fix this?

Whenever I search something and there is a youtube video included in the search results, all links direct to that video. In the example image it show me hovering over a website link and in the bottom left hand corner it instead tries to open a youtube link at the bottom of the page.

I used to be able to clink on an image link prior to a Firefox update (I don't know which one) to go to that site. Firefox gives me that it cannot find the server. What can I do to correct this problem?

Investigate why Firefox is not opening links from third-party apps. Firefox is my default web browser but this issue is making my experience difficult as I have to copy the link and use a different browser.

Links don't work reliably in Firefox. For example, I can't pay with PayPal when making a purchase because clicking the "PayPal" link doesn't open the PayPal page.

Is there a Firefox setting I need to change, or do I need to switch to a different browser?
