Firefox Community Forum

I had around 3000 tabs open I closed the browser completely today. Normally when I reopen firefox all those tabs were appearing still. This time none of the tabs restored I can see tabs in history part namede 19.01.2026 although not all my tabs are there. When ever I try to reload them from the restore history part; firefox doesnt reply and doesnt take the command.

when I clicked on firefox icon today, bing browser appeared and I was not able to use firefox until I downloaded firefox again. I would like to restore the firefox I was using, I had several windows open and my passwords stored there. please advise

I have enabled the option to open the previous windows and tabs. I had one window that I always closed last as it had a lot of groups that are important for my work, so it used to open every time I started Firefox. Sometimes, even if I closed the window by mistake without closing other windows, I was able to get it back by pressing ctrl+shift+n.

But yesterday, I might have closed it by mistake and when I pressed ctrl+shift+n , it didn't come back. I wasn't able to access my window and now it's all gone. I don't see anything in recently closed windows in history.

I need those tabs back as they are very important for my work. they were a lot of tabs. I had many groups but now all are gone. I tried by using the previous.jsonlz4 in the sessionstore-backup by renaming it in the default-release profile as sesstionstore.jsonlz4 but still wasn't able to access my window.

I didn't clear my history as the tabs opened in the window still show up in the history.

Kindly help as soon as possible

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.

Starting about three weeks ago I began receiving the following message when trying to access the above website: Access Denied You don't have permission to access "http://www.kohls.com/" on this server.

Reference #18.cc1c2117.1772495056.333a13f3

https://errors.edgesuite.net/18.cc1c2117.1772495056.333a13f3

Note that the site listed in the error message does not contain the S in https. I manually typed the address with the S and received the same message. I found your correspondence with aprilbrown77 on 8/15/23 and tried all the solutions suggested with no success. I believe Kohls change something on their website 3 weeks ago. My operating system is Windows 7 - 32bit and my Firefox version is 115.33.0esr. I have contacted others using Windows 7 and they all have the same problem. Please update Firefox to resolve the Kohls website issue for the millions of us using Windows 7. Thanks.

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.

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.

Hi,

I use Firefox app in macos, android and ipados. The bookmarks across them are not synching automatically. I need to press sync manuelly to do. All apps are updated, all settings look fine. Please help me synch bookmarks across platforms. Thanks a lot.

This tab group notification seems to be bugged or something. It just keeps reminding me over and over and over and over.

Any help would be appreciated.

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.

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?

I use Firefox on a Mac to access Brightspace for my classes. I also use Grammarly. When copying text from the Grammarly widgets and pasting it into the Brightspace HTML editor, the text is stripped of hard returns, causing paragraphs to collapse without any breaks between them.

I have tried pasting as unformatted text, and the issue persists. This issue does not occur in Chrome, so I suspect it is due to how Firefox handles clipboard data. I have not found a workaround or resolution for this.

the clear option on search bar is not working i troubleshoot , restart and even reinstall the Firefox but it is not working . All other options like microphone camera all are working except clear option

Yesterday, possibly related to updating to version 148, my profile completely disappaered. My old profiles are not visible under about:profiles, but are present on disk. They can not be imported with firefox -P. How do I get my profile data back?

When I try to connect to www.qsuper.qld.gov.au, I get this message:

I have checked that javascript is enabled and I do not have Ghostery or NoScript plugins. Interesting, the "support article" was hyperlinked and I could not access that either. (https://ds.tl/help-third-party-plugins, and the message is"server not found") I have rung Qsuper who advise me that there website is fine. Please advise any strategies. Many thanks in anticipation.
