Firefox Community Forum

I am running Firefox on Kubuntu, which means it comes pre-installed as a Flatpak.

I was having problems with various web sites so I decided to try using the version of Firefox installed with the file found here - https://www.firefox.com/en-US/thanks/

There were no problems with the install. This version of Firefox showed the same issues as the Flatpak version, so I blame the web sites.

Now I have two versions of Firefox. I would like to remove this second version but all the methods I've found do not remove it. I can certainly disable it by renaming the directory created in my user directory /Firefox. Trouble is, shortcuts I created to web sites always launch this version rather than the Flatpak version and I can't find a way to get the shortcuts to use the Flatpak version.

When using the built-in Firefox AI sidebar and clicking the "Summarize page" button, I consistently get the error: "431 Request Header Fields Too Large" from chatgpt.com.

Cookies were cleared multiple times Extensions (including AdGuard) were disabled The issue persists

Previously, changing a privacy setting temporarily helped: switching from "block all cross-site cookies" to "block cross-site tracking cookies and isolate other cross-site cookies". After that, the feature started working.

However, after restarting the browser today, the issue returned, and changing this setting no longer helps.

I would also like to note that currently there is no way to disable or hide the "Summarize page" button, even though I did not need it initially. I tried to configure things so it would work properly, but was unable to do so.

Steps to reproduce:

Open any webpage Open the Firefox AI sidebar Click "Summarize page" Observe error 431

Expected behavior: Page summary should be generated successfully.

Actual behavior: The request fails with HTTP 431 error.

I've recently had a bit of a strange problem. I use on-line banking. When I wanted to print off the latest transactions, I proceeded as usual. Then, when I clicked 'print', the list of transactions was overwritten by an (apparent) HSBC document headed 'Reactivate your unclaimed account'. I could still print my transactions, but only at a much larger font size.

I phoned HSBC and could not get any help. It was suggested I took the printed pages into a local branch (fine suggestion with all the branches that have closed!). I did. I also took my pinpad into the bank so I could sign in on their computer. Surprise, surprise, the strange document didn't appear. The bank said that it must be my browser at fault and suggested I update the version. However, they were able to confirm that all my accounts were fault and trouble-free, with no suspicious activity.

This evening, I tried to do just that. Nowhere could I find any way of updating Firefox, so I deleted the entire app and reloaded it, using Edge. Once set up, I tried again. I still get the document. If I try using Edge, I don't get the document. Now I'm completely puzzled. What makes me even more suspicious is that this strange document shows all of my HSBC accounts, with the correct figures, but at the foot of the first page, in large letters, is the line "Are you sure you want to redirection?". Very odd language. At the head of the second page is another line "You will be token to a new page to login an view your credit card details". More odd language.

This problem has only occurred on Windows 11 - it never occurred when I was using Windows 10. My anti-virus software (Bitdefender) reports my system is clean. The problem also does not occur when using any other web browser.

My conclusion is that there is a problem between Firefox, Windows 11 and the HSBC online app.

Please can this be investigated. Many thanks, John Jesson

Firefox update did not fully complete. All bookmarks have been lost. I did not have a back up file. Can I still get them back? It's still asking to finish setup and has not completed.

What happened, All my important bookmarks are missing. I have had to log into every account I have, No saved passwords. Really upset. I need help to restore all this information that I need

vary unhappy with the new update. never have had issues with fire fox like this. when going to zillow.com i get this message: upstream connect error or disconnect/reset before headers. reset reason: connection termination. I noticed this is only the fire fox browser having this issue. i have already disabled ad blocker and vpn reset fire fox lost all my tabs! reset the computer and nothing still, i get the same message. i have used fire fox since it was a thing and recommending it always. getting a different browser right now to do my house buying, i don't feel safe using fire fox for this adventure any longer. my apologies if this seems like an emotional decision but i see this in everything that gets to big they lose the plot its an infection that is embedded in everything now, windows, home and car pricing. major changes to os and how its used. company's hate there customers anymore and were noticing.

I don't know which topic describes my question. I want to put the New York Times as a short cut on my firefox home page and it won't do it. For a bit of history, I USED to have the short cut and one day it was removed by Firefox when it re-arranged things.

I've disabled HTTPS only mode. When i enter a local http://server.localdomain server Firefox upgrades that to https://server.localdomain. How do I disable that?

Someone seems to have messed with the search tab. For better or worse, I use Google most of the time, The search tab used to default to Google. If I occasionally want a different search tool, e.g. Wikipedia, I would use the dropdown list. Now it seems to default to the last used search tool. How can I get rid of this "improvement"?

It seems that most times Firefox does an update, it deletes the Amazon UK search tool and does not provide any option to put it (or any Amazon tool) back. Where is it on the list of search tools?
