Cannot connect to BBC Sounds web page (https://www.bbc.co.uk/sounds). Get the following error message: "The page isn’t redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies."

Have tried with and without a VPN, have cleared the cache, and shutdown/restarted Firefox, but no luck.

Connects without issue when using alternative browsers.

I am currently trying to set up automatic backups to a local network folder. I have set browser.bookmarks.autoExportHTML and browser.bookmarks.file via the about:config page. This creates the backup on X:\bookmarks.html as desired, but only this one backup. Is there another way to create the backups with a timestamp and to keep to the maximum number via browser.bookmarks.max_backups?

Last night I had an operating system update. Before the OS update, I closed all open apps, including Firefox. In the past, the session I closed the previous evening was restored. But this morning, all my pinned tabs and other open tabs are gone, and Restore Previous Session does not appear as an option on the dropdown menu. Recently Closed Tabs is pretty random, not really helpful. Recently Closed Windows only shows one tab that I opened this morning (probably a mistake on my part). Is there any way for me to retrieve the session from yesterday?

При нажатии на ссылки некоторых сайтов выходит страница с адресом, но содержимое пустое либо белый экран окна, либо черный, в зависимости от сайта, ничего не смогла понять, другие сайты открываются отлично. Например notion открывает черной страницей, мой газ https://мойгаз.смородина.онлайн/ открывает белым, mail.ru открывает но дальше все письма внутри начинает открывать чистыми вкладками. И это происходит не зависимо от того включен VPN или нет, загружает одинаково, произошло сегодня после перезагрузки компьютера. Сайты рабочие, проверено с этого же компьютера но другими браузерами. Как решить проблему? Это малая часть сайтов которые не работают.

Subject: Request for Custom Provider Support or Grok Integration in Firefox AI Chatbot Sidebar

Detailed Description: I am exploring the new AI Chatbot sidebar feature in Firefox (Ubuntu build). As a practitioner in the deep learning field, I am particularly interested in the flexibility of the Web-view container used for these AI integrations.

Currently, the feature appears to be a curated list of providers (ChatGPT, Claude, Gemini). I would like to request the addition of Grok (by xAI), or more importantly, a Generic Provider Framework that allows users to manually configure custom endpoints.

Technical Specifics & Implementation Questions:

   Manifest Configuration: Is the sidebar AI provider list controlled via a remote settings push, or is there a local about:config or JSON manifest (e.g., within the browser resources) that can be modified to include Grok's web URL?

   Context Injection: How does the current sidebar handle DOM context for features like "Summarize this page"? If I were to manually add Grok via a side-loading method, what are the required API hooks for it to achieve parity with the built-in providers?

   User Agent & Authentication: Are there specific CORS policies or User-Agent strings enforced within the sidebar's iframe/browser-view that would prevent Grok’s X-auth or real-time streaming (SSE) from functioning correctly?

Use Case: Integrating Grok’s real-time information retrieval directly into the browser’s native sidebar would significantly optimize research workflows involving live data, which is a key differentiator from the currently supported models.

With dailyexpress.co.uk using Firefox there are two pop ups. One is breaking news on each page using right links and the other is a subscribe to read any of the site, which is recent but prevents reading the site. This does not happen using Microsoft Edge.

As of recent I increasingly have issues with accessing websites, those websites previously (yesterday) worked fine on Firefox. Version is 148.0 on Mac 26.3 (Apple M3 Silicon).

Now it has completely stopped working. Only websites using direct IP-address still work, all others fail with "Hmm. We’re having trouble finding that site.". Safari still opens the websites flawlessly.

Nothing has changed on the OS level or application level as no updates have been installed (no need, as everything is up to date). Antivirus is BitDefender with extension for Firefox enabled for already an extended time (year or so).

I tried disabling several dns.resolver settings as mentioned in https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can. No improvement whatsoever.

I quit firefox, removed the cache manually and restarted while starting a new test profile, so completely blank. Issue is still there.

DNS Servers on OS-level are correct.

Version 148 was installed last night evening and as such could be the reason for the failure since it is basically the only thing that changed.

Why can't Firefox open .mht email extensions within its default browser? It has never done so to my knowledge. They always point to Internet Explorer or Microsoft Edge.

Often an email may not display images correctly and the ability to open them in a web browser is offered, "If there are problems with how this message is displayed, click here to view it in a web browser." This is certainly a development addition when people view their Gmail from Firefox or use Outlook. Not everybody uses APPS. People who don't want Microsoft Edge watching every move they make have made effective permanent changes in removing the deep embedded PUP by Microsoft.

Firefox version: 148.0
