I opened Firefox (V 145.0.2) on my Windows 11 laptop today and noticed that the starting window was the only one open, while I have had at least five windows open for quite some time. The "History|Recently closed windows" option is greyed out. I have closed and restarted Firefox dozens of times and my windows always came back until today. Is that window/tab history stored somewhere where I could recover it?

Thinking about backups of the browser state, I looked for my profile folder and discovered that it is empty - \Users\<username>\AppData\Roaming\mozilla is empty except for a file named vpn.moz. I then discovered that my profile seems instead to be stored under \Users\<username>\AppData\Local\Packages\Mozilla.Firefox_n80bbvh6b1yt2\LocalCache\Roaming\Mozilla\Firefox\Profiles with the folder name e5di8bjy.default-release I now learned that this location is standard for installation via the Microsoft store - the so-called MSIX version. But it is wrong that the "About"profiles" page shows that my profile is in the AppData\Roaming, not the Packages, location. When I try to open that profile folder, I get a message telling me that it is not available on this computer. It seems like the profile info should be aware of the actual location?

I have been dealing with an issue in Firefox on Windows 11 for several weeks now hoping for a fix soon but it has not come yet. When I am browsing on eBay, it will lock up and I have to identify the thread in Task Manger and kill it (just the runaway thread, not the entire program). I can then continue of eBay for a short time before it happens again. This only happens on eBay while just browsing, not bidding/buying. Is anyone else having this issue?

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.

When i try to insert a screenshot through the clipboard on google or yandex image search, the original image is corrupted. Even i try to upload an image via classic upload-button the same problem reproduise. On other sites there is no similar problem, as well as trying to insert the same image but inside the application windows.

In attachement: yandex/google and default image i was trying to upload.
