Firefox Community Forum

During the last week I have had the same issue come up on two computers. When starting firefox, the previously saved windows come up blank (no tabs, no content) and nothing works (no opening new tabs or urls). I was able to get firefox back to working condition by renaming extensions folder and then copying extensions one by one back to normal extension folder. When I copied 'newtab@mozilla.org.xpi' the issue came up again. Also, the new tab extension keeps auto adding it self every other boot.

Firefox: 144.0 (64-bit) - Mozilla Firefox for Ubuntu - canonical - 1.0 OS: Kubuntu 24.04.3 LTS x86_64

I am using the (unsupported) compact mode for firefox UI density.

the manifest.json for newtab:

{"manifest_version": 2, "name": "New Tab", "description": "", "version": "145.0.20250919.173227", "browser_specific_settings": {"gecko": {"id": "newtab@mozilla.org", "strict_min_version": "142.0a1"}}, "hidden": true, "background": {"scripts": ["webext-glue/background.js"]}}

All my addd ons (Ad Blocker, DuckDuckgo privacy essentials, Sound fixer, To google translate) are all turned on but they are all disabled. Maybe since this last update?

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)

This topic was already dealt with at https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://support.mozilla.org/si/questions/1491724&ved=2ahUKEwjh3JWX1KSRAxWDyMkDHYXfDf0QFnoECBsQAQ&usg=AOvVaw2Zp2I2jgPnZ9gkSf5UgMGS. The solution given there was to change extensions.screenshots.disabled in about:config.

Unfortunately, my Mozilla Firefox (ver. 144.0 (64-bit)) doesn't have extensions.screenshots.disabled. So what now?

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.

Will the important announcement of the closure of Beijing Firefox and the termination of Firefox account services lead to the use of the clipping plugin that I previously installed in the Firefox browser

what should I do if I want to continue use clippings in my daily job

I switched from chrome to firefox, chrome has a function for extensions to work in the "background", but here I can't find this function, without it I can't switch songs with binds when something else is open

FF 142.0.1. We have used FF fir many, many years, and NEVER, that is NEVER, been able to ad an extension to our toolbar. Yes, we have read myriad posts and sundry blogs where most of the advice we see is totally useless because the things we are supposed to do not exist in our FF. We can’t add in the customise palette, the extension manger Pin to Toolba, settings, et ceteras. So, how do we add an FF extension to the toolbar in FF 142.0.1? Thank you

Before Firefox added Tabs, I added the Simple Tab Groups extension. How do I move the contents of my many STG tabs into Firefox tabs? Also, there are different colored boxes on my top bar, with my STG tabs, and hovering yields "Unnamed Group Expanded/Collapsed." are these FF tabs?

I have an extension in Firefox that automatically opens with Firefox opens. For security, how can I set it so this extension requires me to enter my password when I use it in Firefox?

Hello, I wanted to create a script that doesn't allow me to disable a certain extension. For that I thought to locate the file in which the states of extensions are put. I searched online, and the answer appears to be that such file is available in extensions folder in my profile. However, I am unable to find extensions folder under my profile.

I would appreciate the help.
