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.

hi, does anyone know where could i find installed extension to work, because where ever i find FE(search by image) it's look like extension setting environment. or any info abt how can i add option to contextual menu sub menu....! thank you in advanced 🙏🙏🙏🙏

does anyone know how to alphabetize the Simple Tab Groups drop-down list?

i have a lot of groups that are constantly changing position and it makes it a rear bear to find the specific group i need.

it says it can do this, but gives no useful instructions and i've tried every avenue i can think of. i do have this checked in the settings for this feature, but the settings don't seem to communicate with the program very well.

Thanks! wolfgang

Hello, I use the Last Pass extension. My job requires the use of multiple websites throughout the day and the extension used to stay open until I closed it. There are options in the extension to set it to not close until I log out. Right now, it is set that way, but continues to log off after 15 minutes. Here's what I've done so far to try to solve this problem. 1. Uninstalled and reinstalled the Last Pass extension. 2. Cleared all data from Firefox. This was recommended by Last Pass when I contacted them. 3. I uninstalled Firefox on my laptop. When I reinstalled it, it automatically recognized that I had previously used it and it zipped through the setup. Maybe still held on to the old settings?

Firefox and Last Pass are on the latest versions. I'm using Windows 11. Other suggestions?

Thank you, Catherine

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.

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"]}}

Hello I have Firefox 144.0 (64-bit) installed. I added Video DownloadHelper to Firefox, but its icon doesn't appear in the Firefox toolbar. I've tried using Toolbar Customization, but the Video DownloadHelper icon doesn't appear there either, so I can't drag it to the toolbar. Can you help me put the Video DownloadHelper icon on the Firefox toolbar? Thank you
