Firefox Community Forum

Suddenly I can no longer connect to gmail or googlemail on mozilla. It works fine everywhere else. At present I'm having to use Microsoft Edge for emails. Everything else on Mozilla seems to work fine. I don't get any messages to say why. The input just sits there with the fullstop going left and right. Any ideas ?

I have no idea what Firefox did with the update but it made navigating my Substack a royal pain in the neck. I cannot post, cannot edit, cannot share posts. Very infuriating. I have had to go back to Edge to get these features to work. Dashboard link does not work. Share link does not work. Cannot post comments. Infuriating.

Hey there,

Whenever I use the picture in picture feature on Firefox to watch something while doing other things,it has randomly gained these black bars on the side of the image and I can't work out what is different? If this is a quick fix, I haven't been able to find it, sorry!

Thank you in advance!

Hi, I need help with an issue related to how my website https://forganica.com/ loads in Firefox. The site works fine on Chrome and mobile browsers, but in Firefox some elements are not rendering correctly and the layout shifts on scroll. Is there a recommended way to debug layout or CSS rendering issues specifically in Firefox? And is there any Firefox-specific setting or developer tool I should check to understand why my site behaves differently?

I am currently using Windows 11 and Firefox 145.0.2 on my desktop computer. Firefox is set as my default browser. Since the latest Firefox upgrade, the "Downsize/Minimize/Exit" toolbar does not appear upon opening and the only way I can close the program is to go to File<Exit, but I still have no way to downsize to share my screen with other applications. I sometimes have to open and close the program a couple of times before the Minimize toolbar appears. I already tried Firefox "Refresh" but the issue is still happening. </p>

Dear Community: What settings can I use so that the sites I continually use recognize me. I have to sign into my email many times a day and also to the New York Times Games which I subscribe to. Is there a way to allow these sites to recognize me without having to go through signing in each time. Even if I log out and a minute later I need to go back on. I have to go through the rigamarole of signing in yet again.

I do not have to do this on my phone as the sites recognize me. I used to be able to do this on this computer also now I can no longer do it. I believe there is something in Firefox settings that is causing this but I don't know what it is or how to change the settings that are causing this.

I’ve developed a Firefox extension similar to the RankingsFactor SEO Chrome Extension, which analyzes on-page SEO elements such as meta tags, headings, links, and canonical tags.

The core functionality works fine in Chrome, but when I ported it to Firefox using the WebExtensions API, I’m facing permission issues while trying to access or read the page content (DOM).

Here’s what I’m trying to do:

Inject a content script to read <meta> tags, headings, and links.

Display this extracted data inside my extension popup.

However, in Firefox, the script doesn’t seem to have proper access to the page DOM — even though I’ve included "permissions": ["activeTab", "tabs", "<all_urls>"] in manifest.json.

I’d like to know:

Are there any additional permissions required in Firefox to read page content?

Does Firefox handle activeTab or content_scripts differently than Chrome?

Is there a specific event or user action needed to grant temporary permissions?

Any help, code examples, or guidance on fixing these permission restrictions would be appreciated.
