Hi! I was wondering why nearly every single page these days opens to the message :

"400 Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. Apache Server at canvas.instructure.com Port 80"

Nearly every link I click on a website refuses to open! It has become impossible to do school work on this browser because I can't open any link on my school website, and nearly every website struggles to open except from google. I know the links work because I copy/paste them into Google Chrome and they open immediately. Truth be told I prefer Firefox and would much rather keep using this browser! I also can't find an update for Firefox so I believe my Browser is up to date (and I know my laptop is up to date and virus free). Is there a fix coming soon? Or a setting I can change to be able to open links? Classes start this week and I'm stuck!

Thanks for your help!

So some website didn't work for me and I pressed "forget" button thinking it only removes history from a particular website (no). That's it - EVERYTHING COLLAPSED, session is lost, all tabs gone. Trying to restore from "sessionstore.backup" - no result. Trying from synced - oh sure CRAP IS TURNED OFF like always for NO reason

Thanks a lot, douchebag morons. Hope you all die + anyone suggesting to copy "sessionrestore" gets testicle/boob cancer + anyone suggesting to turn sync on can eat my crap

I'm trying to use Microsoft Teams in Firefox because the native app for Linux is abandoned and crashes, and at first sight the app is blocking Firefox on purpose. Buttons to make calls are disabled, stating that audio and video are not supported in my browser, but everything works normally if join to existing calls using e.g. links.

Is it possible to trick Teams to think I'm using Chrome? I found the "User-Agent Switcher and Manager" add-on, but I can't figure out how to possibly use it.

Any ideas why I am seeing these strange rectangles on Google maps?

Confirmed not caused by an extension as I still see them in Private window and do not see them when using Brave.

They don't stay in the same geographical location when zooming in and out.

Is spell-checking done locally on my computer, or is it done on the Mozilla website? I just found out that the Chrome and Edge browsers send my typed message to the home office, and that is where the spell-checking is done. Can I assume that this process is done locally on my own computer with Firefox?

I've been paranoid about security for many years, and every little bit of info I can add to my personal well-being lets me sleep that much better at night.

I am currently 82 years of age and have been using Firefox since it first became available, just because of its advertised security features. Quite happy with it and hope it stays on top of my needs.

And I have the same question regarding Thunderbird and its security properties.

Thank you.

Bookmarks organisation resets to unsorted regularly

Hello Firefox Community,

I've been a long-time fan of Firefox's bookmarks management system, but over the past year, I've encountered a persistent issue that's affecting my productivity. I regularly use the bookmark bar and organize my bookmarks into folders. However, any changes I make don't seem to stick and get reset after a period of time. This is especially frustrating as I heavily rely on bookmarks to keep my browsing organized. Problem Details

Here's what typically happens:

  1. I add a bookmark to a specific folder or position, either in the general list of bookmarks or on the bookmark toolbar.
  2. Sometime later, that bookmark leaves its designated position and moves to the bottom of the unsorted list of bookmarks.

Devices and Operating Systems

  • MacBook M1 2020 running macOS Monterey
  • Dell Alienware 17 r5 running Windows 10

Both devices have the latest version of Firefox installed, and I use Firefox Sync to keep my bookmarks and settings consistent across these devices. Suspicion

I suspect that this issue occurs when I make a change to bookmarks on one computer and then open Firefox on the other computer. The bookmarks seem to reset, possibly due to some issue with Firefox Sync.

Looking forward to hearing your thoughts and possible solutions!

Kind regards,

For a few weeks now, Firefox has been often freezing a webpage for 5-10 seconds during browsing. It mostly happens when going back to the previous page, but also when clicking a link or doing a google search. For those 10 seconds, you can't do anything on the page; no clicking other links or selecting text.

I've already tried: - troubleshoot mode; it still happens when all extensions are turned off - turning on/off hardware acceleration - creating new places databes - updating to the newest version

What can i do to fix this?

I'm having issues with the cursor when opening a new tab and I've tried a few different fixes and none are really working.

When I open a new tab the cursor goes immediately to the start of the homepage URL which is not helpful as if I type it just retains the URL after what I've typing(See Image). I've tried playing around with about:config to get the cursor to populate into the google search bar on the browser home screen but, it doesn't work.

I've also tried setting the new tab page to blank but, then sometimes it doesn't search google even though it says it should and says URL unrecognised(see the other images).

Why is this happening, I just want to be able to not have to manually delete the URL to search using the search bar and this seems like really basic functionality to me.

This is my second email to you....

I just switched to Firefox from Chrome, because Chrome was crashing all the time.

All I want to do is sync my computer, laptop, phone and Ipad's reading list. I want to be able to see an article on one device, add to the reading list, and have it on all devices.

I'm logged in under the same name on all, and it says sync is on, but the reading lists are different.

Can someone help me? My phone number is [removed phone# from public support forum], email is [removed email from public].

Thank you!
