I installed the Multi-Account Container Extension and it worked fine until I added the fifth container. Now the window does not shot the Manage Container button at the bottom, and I can not add anymore containers. I've removed the extension, and restarted Firefox, re-installed the extension, and still the issue remains.

I do not know where to go from here. And if this feature is so difficult to use, or has bugs that I can get corrected so I can use the feature. I will remove it and not even waste my time. I've been using Firefox for over 20 years, but I am not going to continue if the extensions or other features fail to live up to the standards I think Firefox should hold.

I tried taking a screenshot of coping the extension window but could not figure out how to do that. So suffice with the fact that the Manage Account or container button that was at the bottom of the window no longer is there.

What version of Firefox actually allows you to add extensions? I'm running the most current version of Tumbleweed that ships with 144.0. Attempts to add extensions just sit there doing nothing until I close the tab. This sort of worked some time ago (I forget the version) but the inability of Firefox to allow add-ons/extensions is getting to be a joke. There are other browsers out there, ya know.

Hi,

I noticed this on facebook in particular but I want to prevent this behaviour on ALL websites.

I noticed that when I focus away from and back from a facebook tab, sometimes it will blank and reload the page.

I DETEST this behaviour, sometimes the content changes, sometimes it fails and hangs !

Even if it worked properly I NEVER want a webpage to be allowed to do that.

How can I make a page unable to tell when I give it attention.

Here are a couple solutions I would like to see

A toggle button PER TAB, where I can PAUSE script execution entirely. I want the page to load and then all scripting to freeze until I press the unpause button (except for whitelisted pages). For this I found the addon "Scriptsafe" but it doesn't have a per-tab setting.

Another solution is, no awareness allowed to the page about losing or gaining focus. This is also abused by youtube to detect screen shutdown, so I never want pages to know they have lost or regained focus. I want to make them believe they are ALWAYS focused.

How can I do either of these things ?

1. y extensions do not appear at the top of my browser window even though they are enabled. 2. My url field now goes almost all the way across my window!! Moving the window requires careful cursor placement on the edge. 3. When I click the Firefox name on the top of my computer it only offers me the option to open a private window.

I've been using the "Show shortcut when selecting text" feature in Firefox, where clicking the AI ​​icon after selecting text gives me quick options like "Quiz me," "Explain this," etc.

But I've run into a issue: after a certain FireFox update, when I select text and pick one of those options, Firefox does open the Copilot AI sidebar (which I've set as my default), but it doesn't actually do anything after that—it just shows the Copilot new task screen without sending the selected text or performing the action.

（I don't know why Firefox recognized my system as Windows 10, but in fact my system is Windows 11.） Firefox version: 144.0 (64-bit)
