When opening a new website when a window is already opened I want Mozilla to add a tab and not create an entirely new window. How do I change this feature which presumably is in "settings".

So this problem keeps happening to me - I click "upload" on a website and nothing happens. For example, trying to upload photos to my website or upload files to a platform. Frustrating. To work around it I've been using a separate tab of Google chrome but it's such a pain to keep swapping back and forth. Please help!!

My sign-in ID is aaaan email that has been cancelled. As long as they don't asl me to retrieve any codes oranything it works of course. If anything is sent to that email I can not retrieve it. Usually kepping me out of Fire fox. I need to see if amyonr know how to change your sign-in ID>

Thanks Paul

Native manifests describe where native messaging browser extensions can be found, as described here:

https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Native_manifests#native_messaging_manifests

Specifically on the MSIX version of Firefox available in the Microsoft Store, what directory does Firefox look in for native manifests?

The problem I need to solve is that I need to place a native manifest in a location where Firefox can see it, specifically in the new Windows MSIX installer. This seems to be reasonably straightforward, if I can confirm where that is.

Hello support,

is there any way (other than the one plugin I found that did not work for some reason) to adjust firefox' general brightness (or that of an individual tab) ?

Also changing my monitors brightness would not work for me as I am trying to test a website I develop (using firefox to visualize it) and it is rather just the large difference between my editor (which's brightness you can not adjust) and the browser that is very unpleasent when I switch back and forth (like when trying to fix a bug).

Kindest regards.

I heard that the newest version of Firefox (which I have not upgraded to yet) has a feature that makes it easier to accidentally visit a website whose URL is on the clipboard. I googled to find out how to disable it, and the Featured Snippet said "go to about:config and change clipboard.autocopy to false." Sounded simple, so I did it, but subsequently found out that the article it quotes from is 10 years of age!

My first question, then, is: what does changing "clipboard.autocopy" to false do if it doesn't turn off the brand-new feature?

The second question is, how do I disable the new URL Paste Suggestion feature? Will setting "clipboard.autocopy" disable it? In particular, I want to make sure that the browser does not pre-load or pre-fetch the clipboard URL, and in fact, I wish to pop up a dialog box any time I do "paste and go." People often copy URLs from e-mails to research them before visiting them directly; jumping directly will increase the likelihood of visiting an imposter site.

I have Firefox 124.0.2 running on Windows 11. For some reason, I can't update Firefox. When I manually download the update file, it appears to run Ok, but the version doesn't change. If I go to settings and click on "Check for Updates" is comes back and says Failed to Check for Updates. How do I fix this?

Originally reported on April 11th /questions/1444593: I have Windows 11 and the Firefox 124.0.2 browser. I cannot update to the latest version of Firefox. I receive an error message "Failed to update". I've uninstalled and reinstalled the browser, ran the install utility selecting update, nothing seems to work. Please help

I am running Windows 10 (64-bit) Version 22H2 OS build 19045.4355 with the Firefox browser v125.0.3 and since updating to the latest Firefox version I am no longer able to load more than 17 Tradingview tabs and the Tradingview tabs I do upload take a long to to refresh or to save changes too. I do not have this issue using other browsers.

Trying to use this site: https://www.asraymond.com/mechanical-wire-springs/compression/spec-metric-compression-springs-131626/?Imperial=false

Near the top of the page on the right hand side you can switch from imperial to metric units. The link is set to metric values, but the search input is still using imperial dimensions (see this on the left side of the page as you scroll down) But it works in Chrome!

The is one a myriad of problems I have encountered with Firefox. My installation at home frequently stops searching. It won't perform a web search. Typically when I fire up Chrome in frustration to this constant event, Firefox starts working again. I have removed and reinstalled Firefox, but this did not solve the problem. It's my understanding the Google finances Firefox. Are these problems intentional?

Web cam image on web page stopped working after last update. Using win 11. Tried refresh, worked last time but not this time, checked permission security settings. Can get the camera image on a tablet but not laptop. (lenovo) Anything I might have missed?
