Every time, but only in the last two days, I try to click through to anything related to American Partisan.org, get a "bad request"error message. I have never had this problem in many years of visiting this site and clicking various linked articles on site. I am still receiving email from this site daily with no problems, but cannot click from the email to the site itself. I am not very computer savvy having grown up using a dial telephone in another millennium. I hope the solution is simple. I have no such problems with the site in question on the same email account on my cell phone. I have no similar problems with any other sites on my computer. Here is the message:

Often when I do an internet query, I get content back in some foreign language...URL: zhihu.com ..... I want to block this URL from my computer. How can I do this?

They [rimary password quit woking so changed it in mozzzila account which I'm logged into the browser, but it will not allow me to change the primary password in the browser or access a lot of stuff, . I updated the Password in the Mozzilla account, and since doing that the browser fails to sync.

I cannot figure out how to fix this in a lenovo laptop running stupid windows 11

I've used firefox for quite awhile, recently, incognito mode stopped deleting the sites visited while it's in use. It appears that none of the settings have changed. I'm told there is a box to check if you want your history while in the mode to be erased. I do not remember ever having this before and it seems counter intuitive.

Hi. Awhile back alot of stuff was going to Spam that shouldn't have, never did before and it was frustrating. It just started out of the blue. I have a few email addresses and it happened to all of them.

Then I've noticed over the past couple of weeks that the spam folders have disappeared. Don't know why. Of all things, I want my spam folders back so I can see if I'm missing something important. If I don't have spam folders, and I'm getting false spams, where are they?

Did TB delete my spam folders in some update?

I have used FireFox for years now and I am happy but... yesterday after I synced my info across two computers and my Android phone, suddenly my wallpaper selection on my laptop disappeared.

I had a photograph and instead of seeing it? I have a white background and the photographer's name who took the photo but the photo is no longer showing as my wallpaper..

BUT I went to edit the wallpaper and selected a color but it doesnt appear. no item I select from the menu of wallpaper items actually appears on my browser

Please help if you can! Firefox on my other computer is working fine in this regard and this one WAS working fine until yesterday after I synced the devices.

thanks, Keith

Since buying a windows 11 laptop, text on websites on my remote monitor usually appears to be roughly "printed" and lightly "inked", but will temporarily become darker and normal appearing at intervals from 5-30 second, but will soon revert to nearly unreadable. Text appears normal on my connected laptop monitor. The remote monitor text appears and stays normal when I run in firefox troubleshoot mode, but reverts after I turn troubleshoot mode off. I've refreshed firefox, replaced the xulstore.json file. Nothing has helped except running in troublehoot mode. Help!

When I let thunderbird compress the inbox and other folders, the not read flags on all new emails get reset as if I have read all of the new emails. Compressing the inbox and other folders should have no effect on the flags showing a message has not yet been read. That only makes sense. The not read flags getting reset started happening several versions before 145.

What does the icon that shows (for a while) against the SUBJECT line of messages indicate?

After some time, or perhaps following my general activity within the application or some other trigger, it seems to disappear for reasons I have yet to understand.

I attach a screen clip showing four of these icons ("2025 - STILL TO REVIEW" is one of my user-created folder names.)

Secondly, is the answer to the above question available already in online help for Thunderbird? If so, and since I haven't found it yet, I would be grateful to be pointed towards the relevant article. As a new user, I expect it would tell me other things that will be useful for me to learn!

I am using version 146.0.1 (64-bit).

Firefox is showing a badge on its dock icon. It's a flower. I think! But I have no idea what it means. What does it mean?

(No topic best described my question, so I picked one at random.)

Hello Firefox Support,

I am experiencing a consistent and disruptive performance issue that occurs immediately after certain complex web pages (particularly those with heavy scripting or dynamic content) have fully loaded.

The symptom is a temporary but complete freeze of the Firefox window, often lasting between 5 to 10 seconds, during which time the browser is completely unresponsive. This freeze is accompanied by a significant spike in CPU usage (often reaching 90-100%, according to Task Manager/Activity Monitor).

Details:

Trigger: The freeze reliably occurs right after the page status changes from "Loading" to "Done." I suspect it is related to post-load scripting execution or rendering finalization.

Impact: Any ongoing user interaction is halted until the spike subsides.

Tested Scenarios: I have replicated this on multiple sites, including heavy news aggregators, social media feeds, and complex web applications.

Troubleshooting: This issue persists even after:

Clearing cache and cookies.

Running Firefox in Safe Mode (disabling all extensions).

Creating a new, clean Firefox profile.

This severely degrades the browsing experience, especially when quickly navigating between tabs or starting a session.

Could you please investigate potential issues within the core rendering engine or script execution scheduler that might be causing these severe post-load processing bottlenecks?

Thank you.

my delete history has not been working since yesterday. I have not changed anything to my knowledge in settings so please help in correcting this. I have looked at settings and not sure if something changed or ?

I have not used private settings at all.

Firefox is my default browser. The problems have arisen from around December 27th 2025. Till then everything worked smoothly. The first problem is that if I go to google.com then search for say , “Wordle”. The search output is displayed on the screen but when I click on the search result, it does not go anywhere- nothing happens.

The second issues, is till the problem cropped up, I had set google.com as the custom url for home page and windows through settings, home, and had used an extension, “ New tab override” available from Firefox, to set every new tab to open as google.com The url for the webpage works but the new tab override does not. I have tried removing the extension but problem 1 persists.

The third issue is that I have subscriptions to newspapers and had set up the logins. These newspapers are in my bookmarks. When I click on the bookmark the main page opens but the login area is missing. It tells me to get a subscription. e.g., among others, NY times, Uniqlo gb, the Turnitin of my university will not load although I am logged in to the university. I have cleaned all cookies, removed all extension including Ad blockers to fix the problem, tried resetting all to default setting but nothing works. Would appreciate any help you can provide. Thank you.

In order to connect to Amazon using Firefox on my PC, I am required to scan a QR code with my phone and then, presumably, connect via Firefox or Amazon apps (instructions woefully unclear). It NEVER works. It's no big deal, but it is annoying, particularly since I want to use Firefox as my default browser. I can always connect via Google or Edge. For those of us who aren't tech savvy, why don't you add standard two-factor authentication or Windows Hello as an option?

When I try to log in to my account with Amazon Prime, Firefox freezes as soon as I hit the Continue button after entering the username and password. I can't open or close tabs or do anything. I don't have this problem with the Amazon account in any other browser.

Any ideas why this happens and how to fix it?
