Firefox Community Forum

My problem is as described in the subject line: I'm getting multiple instances of Firefox opened when I click links from email or web pages.

This just started happening within the last couple of days. In the past, whenever I opened a link a new window was opened in the already open instance of Firefox. Somehow some setting has been changed (a guess) that has caused a change in behavior.

Firefox is my default browser, but I do keep Chrome open for some testing of HTML/CSS I'm writing. Chrome is NOT my default browser.

I did some searching without finding anything I understood well enough to implement.

I would appreciate any help with this issue as having multiple instances of the app running is driving my octogenarian brain nuts.

When I enable a theme, it doesn’t apply properly. Instead, the color that appears is just the default color of the browser. Sometimes the theme applies, but when I open a new browser window, the theme I enabled disappears. Why is this happening? Tysm :)

I am trying to inspect dom to see the content of a dropdown for my selenium test and I am facing the following issue:

1. Click on a drop down select (ex Language) 2. It adds a list of language divs to the dom 3. Open Inspector to see them 4. List of languages is is not visible in the dom as it is collapsed in the inspector by default 5. Click to expand the list in the dom 6. That triggers a "click away" event and code removes the list of languages from the dom 7. Back to point 1 :(

Is there any way to break this dead loop? 1. Expand all nodes in the inspector by default 2. Disable any dom manipulation events

Thank you!

My Bookmarks do not not show when I open Firefox. I have enabled Bookmarks under View > Sidebars but they don't show and I have to manually make the visible every time I us Firefox.

the right click menu used to be matte and used my windows accent color. now its transparent with a frost effect on top, kinda like the right click menu in windows 11. how do i get the old one back

i'm on an old macbook air running Ubuntu 24.04.2 LTS. i exported my chrome bookmarks into an html file, and tried importing them into firefox. firefox says "577 bookmarks imported", but not a single one shows up anywhere in the firefox bookmarks. what am i missing? Thanks, Nilesh

Typically, I have about 6 windows open at a time with about 20 tabs in each window. Previously, I was able to shut down my computer and all of them would reopen again. But, today is the second day in a row that that hasn't worked even though I have Open Previous Tabs & Windows checked off in the settings.

I would appreciate figuring this out as it's a pain in the ass opening everything again.

• I just noticed that Firefox is supposed to open automatically. This doesn't happen either.

I'm using a LG laptop running Windows 11.

After the last couple of Firefox updates, my settings have been automatically changed. This has not happened until recently How can I stop Firefox from changing my settings when it updates? OS is Windows 11. TYIA!

When I am trying to upload a file to any website in Firefox the right click context menu options are all missing. I have tried a new profile, troubleshoot mode, seems like nothing fixes it. Other browsers work like intended so I know it is Firefox internal

There is no way I can make my FF into a default browser and showing some old exe files from old FF's leaves me with no comprehension to do anything. I follow the three steps properly ending with the FF icon in the browser box. That does nothing - unless I need to acknowledge its done, but where do I do that?

It nags me, that I ain't asked if I want the AI function, you just force it over me without giving me any choice, if I want it..

SO, how to COMPLETELY remove the AI function in Firefox and Linux Ubuntu..

AI scare me and I definitely don't want ANY of it!!!
