I'm using the AI chatbot in Firefox Developer Edition's sidebar and I was wondering if it's possible to set the web page from the active tab as the context by default for all future chats.

Is there a setting (checkbox) for this somewhere?

I have two websites of my own. I am viewing one and it is correct. When I view the other, it uses the https cert from the first one, and says my site is not secure. I have viewed the cert, and it is definitely correct. I think Mozilla is probably caching old information - the certs have been correct for most of 2025, so it is a pretty old version. Therefore, it is not actually caching the cert, but caching which cert it should use. I have tried clearing the cache, and it did not help!

Has Mozilla got some kind of cache I can't clear? Should it not re-read the cert when it loads the site, or at least the cert date, each time it reads the site (ie was not previously showing it on screen)?

Old lenovo laptop put a small dot by firefox symbol when an update was available. New lenovo isn't. Need it to keep running smoothly. Cannot find where to add that in. Could you please direct me? Thanks, Susan B Parvey

Hello-

I have an issue with secondary webpages disappearing. Occasionally, when I am on a website, particularly when I am buying something or comparing items and a pop-out page appears showing what you selected, when I go to click on that 'secondary' webpage it disappears. It's not hidden between other open browsers or appearing on the taskbar. It's just gone. When I go back to the main webpage site and open up this pop-out page again, it will reappear. But the moment I click on this pop-out page it disappears. An example is attached with a DoorDash progress order. It seems that it only happens with "secondary" pop-out pages. It does not occur if the website creates a whole separate new non-pop-out page.

I went into settings to try turning off and on pop-up to see if that does something but nothing. Thanks for your help in advance.

Here is the problem I have: I'm using Linux Mint 22.2 Cinnamon 6.4.8, which has a feature of **Dragging Maximum Window titlebar makes Window Restore Down/Unmaximum**, which also is a feature that Windows has since Vista. I don't like this feature so I disabled it on Windows, but when I tried to disable it on Linux Mint, I realize the setting was broken for a very long time. Only Window to Maximum can be prevented but not Unmaximum.

I think the Linux Mint Developer will not fix it, so what I can do is only to **Just not drag Maximum Window's Titlebar** Here is the issue: **Firefox consider toolbar/bookmark as a part of its titlebar.** When I click or drag the gaps of toolbar, it is considered as titlebar. When this happens, the Maximum Firefox Window gets unmaximum, which is very annoying.

Here is a video I recorded to explain it: <https://www.youtube.com/watch?v=_K7y7MRRKy4>

Is there a way to make the toolbar not a part of titlebar?

Every few weeks at random I have the same problem: Any action I take on tabs (e.g. close tab, open new one), as well as any typing I perform, only creates the normal effect after around 10s of delay. I can type whole sentences and nothing happens until 10s later the whole sentence starts appearing as if I had just typed it. The hamburger menu and about dialog where not impacted from this delay.

The CPU and memory load shows no signs of being a bottleneck and nothing performance hungry is happening in the rest of the system.

This happened around 2min after startup, after 5h of work, or anywhere in-between.

Workaround is a browser restart, but it is quite annoying if this occurs while I'm filling in a form and I have to start over.

Ubuntu 24.04 - snap package Once the issue occurred, I disabled all extensions (without restart), but the issue continued.

We have an enterprise web application that utilizes Primefaces for frontend UI. With a newest version of Firefox ESR 140.2.0 we noticed that input field values history is not saved. So the values are not proposed to the user wen he enters form data again. Problem is not available in Firefox ESR 128.14.0. Old input field values saved in 'formhistory.sqlite' before Firefox was upgraded to 140.2.0 are still available for the user.

Hello, I encountered this issue while trying to Ask a Question in Simplified Chinese. For example, Firefox's Chinese Simplified Language Support page.On the Simplified Chinese page (https://support.mozilla.org/zh-CN/questions/new/firefox), clicking the "Continue" option in the "Ask a Question" section redirects to https://support.mozilla.org/zh-CN/kb/%E8%8E%B7%E5%BE%97%E7%A4%BE%E5%8C%BA%E6%94%AF%E6%8C%81?exit_aaq=1. Then, clicking "GET HELP" redirects back to https://support.mozilla.org/zh-CN/questions/new/firefox. Under normal circumstances, it should redirect to the Question submission page. This feature works correctly on the English-language Mozilla Support page (https://support.mozilla.org/en-US/questions/new/firefox/form). I attempted to change the language identifier in the English page URL from "en-US" to "zh-CN," which resulted in a prompt stating: "The question forum cannot be used for Firefox in Chinese (Simplified). We have redirected you to the English question forum." And I found that none of the ask a question in Support can be used in simplified Chinese language. I tried to ask Mozilla Support, but I didn't get valid information.

How can I get the tabs back that I had open before a Firefox Update? They're not coming up using Restore History. I had a lot of things open that I want to be able to go back to.

Thanks, Bill

My bookmarks do not sync between my Android( Samsung 22 Ultra) and my Desktop( Windows). I show this issue as when I would delete and update bookmarks on my mobile. They did not update on my computer. I have tried signing out on my computer, which wiped out the bookmarks and other saved attributes. Then signing back in. This did not work. My bookmarks menu is bare. Even though in my account I have both my mobile and computer accounts connected. What can I do to fix this?

Some background, the bookmarks and other saved attributes where from chrome, I transferred them over.

Recently I am unable to pull up saved passwords when logging on to sites I use regularly. I can go to Settings, Privacy & Security & check the box "Ask to Save Passwords". The saved passwords then stay on even if I close & reopen Firefox. All is then well until the next time I restart the PC. Then it defaults back to an unchecked box. How can I set the PC so that the "Ask to Save" button stays on? Upgraded to Windows 11 about 1 month back. Thanks.

I recently installed Win 11 on a new Acer Aspire (with MSI MAG244F monitor) but the issue seems to be present on my Acer Nitro 5 with built-in monitor as well.

I don't think it's an Acer issue but I am only running Win 11 on the two Acer machines. If I open a web page with colored graphics or pictures and then drop down a menu of the browser (bookmarks, etc.) the colors of the graphics bleed through. It's annoying and somewhat obstructive. It does not occur if a window from a different app is opened on top of the browser window no matter how bright the colors are.

I attached a few edited screenshots to show the issue. The edits are only to cover personal information etc.

The issue seems to be color saturation and does not occur on my other Win 10 machines or in other browsers. Not even the same version Firefox on the Win 10 machines.

Is there a way to increase the opacity of the drop downs or lower the color saturation in the Firefox browser?

Hi, I'm a developer and I was having some issues with my service worker so I unregistered it from firefox (probably should've double checked what that did, oops) but now I can't get it to reregister again. The service worker will show up when I load the site from private browsing but that's because the origin will show private browsing. Have I just blocked my url from registering a service worker? How can I undo that?
